spring cloud gateway

The following example configures a KeyResolver in Java: This defines a request rate limit of 10 per user. projects are imported into Eclipse you will also need to tell 2. The Spring Cloud Gateway project is built on top of the popular Spring Boot 2 and Project Reactor, so it inherits its main treats: Low resource usage, thanks to its reactive nature. The Before route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). Instead, this time well focus on a particular usage scenario that arises from time to time when designing a solution around an API Gateway: how to process a backend response payload before sending it back to the client? You can find them in the spring-cloud-build-tools module. You can configure the logging system to have a separate access log file. Those values are then available for use by GatewayFilter factories. It uses Java regular expressions for a flexible way to rewrite the response header value. outcome: The outcome, as classified by HttpStatus.Series. These are special filters that are conditionally applied to all routes. URI variables may be used in the value and are expanded at runtime. Multiple matching segments are allowed. By default, the gateway defines a single predicate and filter for routes created with a DiscoveryClient. Any example of fully covered test cases please? See the Spring Cloud Project page for details on setting up your build system with the current Spring Cloud Release Train. The accepted values are RETAIN_FIRST (default), RETAIN_LAST, and RETAIN_UNIQUE. Hence add the property suggested [spring.main.web-application-type=reactive]. This is useful when you try to support CORS preflight requests and your route predicate does not evalute to true because the HTTP method is options. Easy to extend and/or customize using standard Spring patterns. To configure Global http timeouts: to the exchange attributes. URI variables may be used in the value and will be expanded at runtime. The body is cached in a request attribute defined by. There click on the icon next to the Scheme section. If you dont have an IDE preference we would recommend that you use The following example configures a before route predicate: This route matches any request made before Jan 20, 2017 17:42 Mountain Time (Denver). URI variables may be used in the value and are expanded at runtime. Route These are the building blocks of the gateway which contain URL to which request is to be forwarded to and the predicates and filters that are applied on the incoming requests. There, click on the Import Scheme value and pick the Intellij IDEA code style XML option. The FallbackHeaders factory lets you add Spring Cloud CircuitBreaker execution exception details in the headers of a request forwarded to a fallbackUri in an external application, as in the following scenario: In this example, after an execution exception occurs while running the circuit breaker, the request is forwarded to the fallback endpoint or handler in an application running on localhost:9994. The following example configures a DedupeResponseHeader GatewayFilter: This removes duplicate values of Access-Control-Allow-Credentials and Access-Control-Allow-Origin response headers in cases when both the gateway CORS logic and the downstream logic add them. install wscat. Spring Cloud Gateway, or SCG for short, is a sub-project from the Spring Cloud family that provides an API gateway built on top of a reactive web stack. The RemoveResponseHeader GatewayFilter factory takes a name parameter. To create a route, make a POST request to /gateway/routes/{id_route_to_create} with a JSON body that specifies the fields of the route (see Retrieving Information about a Particular Route). Go to File Settings Editor Code style. Here, well use one thats commonly used by the out-of-the-box filters: AbstractGatewayFilterFactory, a templated base class, where T stands for the configuration class associated with our filter instances. Retrieving the Routes Defined in the Gateway, 15.5. You can adjust this behavior by setting the spring.cloud.gateway.filter.request-rate-limiter.deny-empty-key (true or false) and spring.cloud.gateway.filter.request-rate-limiter.empty-key-status-code properties. Spring Cloud Gateway is an API Gateway / Backend For the FrontEnd (BFF) framework. per-route http timeouts configuration via configuration, per-route timeouts configuration using Java DSL, Example 64. The redis-rate-limiter.burstCapacity property is the maximum number of requests a user is allowed to do in a single second. AddResponseHeader is aware of URI variables used to match a path or host. Spring Cloud projects require the 'spring' Maven profile to be activated to resolve regexp, so green and greet would match. If Spring Cloud Gateway is, for example only accessible through HAProxy, then a value of 1 should be used. exceptions: A list of thrown exceptions that should be retried. The unmodified original URL is appended to the list in the ServerWebExchangeUtils.GATEWAY_ORIGINAL_REQUEST_URL_ATTR attribute. tracker for issues and merging pull requests into master. The Spring Cloud CircuitBreaker GatewayFilter factory uses the Spring Cloud CircuitBreaker APIs to wrap Gateway routes in In our case, we only need two configuration properties: The key method we must implement is apply(). It does not work in a traditional Servlet Container or when built as a WAR. We use the projectRoot/src/checkstyle/checkstyle-suppresions.xml. In our case, were not converting types, so both input and output use the same class: JsonNode. As filters are a core concept in SCG, all we need to do to support response processing is to implement a custom one that applies the desired transformation. Writing Custom GatewayFilter Factories, 17.2.1. This section details how to retrieve route filters, including: To retrieve the global filters applied to all routes, make a GET request to /actuator/gateway/globalfilters. The following example shows how to achieve the same configuration with Java: Route filters allow the modification of the incoming HTTP request or outgoing HTTP response in some manner. or check if an exchange has already been routed. Learn more. Eclipse Code Formatter Spring Cloud Build brings along the basepom:duplicate-finder-maven-plugin, that enables flagging duplicate and conflicting classes and resources on the java classpath. marketplace". E.g. The following example configures a host route predicate: URI template variables (such as {sub}.myhost.org) are supported as well. If the URL has a forward scheme (such as forward:///localendpoint), it uses the Spring DispatcherHandler to handle the request. Spring cloud gateway provides a library for building gateway API on top of java and spring. GlobalLogic is a leader in digital engineering. The Forwarded Headers Filter creates a Forwarded header to send to the downstream service. Spring Cloud supports Resilience4J out of the box. It consists of ID destination URI Collection of predicates and a collection of filters A route is matched if aggregate predicate is true. To better illustrate how response body manipulation works, lets create a simple filter that masks values in a JSON-based response. Your efforts will make a positive impact on the solution which collects, organizes, and presents information . The AddRequestHeader GatewayFilter factory takes a name and value parameter. README.adoc and process it by loading all the includes, but not After the proxy request is made, the post filter logic is run. The filter takes a host parameter. It requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. The following listing configures a RedirectTo GatewayFilter: This will send a status 302 with a Location:https://acme.org header to perform a redirect. The following listing configures a LoadBalancerClientFilter: The ReactiveLoadBalancerClientFilter looks for a URI in the exchange attribute named ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. The following example configures a MapRequestHeader: This adds X-Request-Red: header to the downstream request with updated values from the incoming HTTP requests Blue header. The following listing configures a RequestSize GatewayFilter: The RequestSize GatewayFilter factory sets the response status as 413 Payload Too Large with an additional header errorMessage when the request is rejected due to size. The following listing configures a SetRequestHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. The Weight route predicate factory takes two arguments: group and weight (an int). You can overwrite the names of the headers in the configuration by setting the values of the following arguments (shown with their default values): executionExceptionTypeHeaderName ("Execution-Exception-Type"), executionExceptionMessageHeaderName ("Execution-Exception-Message"), rootCauseExceptionTypeHeaderName ("Root-Cause-Exception-Type"), rootCauseExceptionMessageHeaderName ("Root-Cause-Exception-Message"). ), The NettyWriteResponseFilter runs if there is a Netty HttpClientResponse in the ServerWebExchangeUtils.CLIENT_RESPONSE_ATTR exchange attribute. The following listing configures a StripPrefix GatewayFilter: When a request is made through the gateway to /name/blue/red, the request made to nameservice looks like nameservice/red. It takes stripVersionMode, locationHeaderName, hostValue, and protocolsRegex parameters. This project provides an API Gateway built on top of the Spring Ecosystem, including: Spring 5, Spring Boot 2 and Project Reactor. The resulting response is similar to the following: The response contains the details of the global filters that are in place. You can configure the SetStatus GatewayFilter to return the original HTTP status code from the proxied request in a header in the response. Go to File Settings Other settings Checkstyle. The redis-rate-limiter.replenishRate property is how many requests per second you want a user to be allowed to do, without any dropped requests. To build the source you will need to install JDK 17. Notice that the returned server is already started and will listen to incoming requests at a random port. you can import formatter settings using the XForwardedRemoteAddressResolver::maxTrustedIndex takes an index that correlates to the number of trusted infrastructure running in front of Spring Cloud Gateway. The following headers (shown with their default values) are added: Strict-Transport-Security (max-age=631138519), Content-Security-Policy (default-src 'self' https:; font-src 'self' https: data:; img-src 'self' https: data:; object-src 'none'; script-src https:; style-src 'self' https: 'unsafe-inline)'. For instance, in the configuration above, apply() will be called only once since theres just a single route definition. Apache, Apache Tomcat, Apache Kafka, Apache Cassandra, and Apache Geode are trademarks or registered trademarks of the Apache Software Foundation in the United States and/or other countries. It offers a simple way to manipulate the request path by allowing templated segments of the path. It uses the Spring WebSocket infrastructure to forward the websocket request downstream. While working with integration tests, hit the gateway service that is started on the endpoint, seeing the requests forwarded to respective services, I was wondering if there is a good practice to test this Spring Cloud Gateway feature. #{@myKeyResolver} is a SpEL expression that references a bean named myKeyResolver. This is equivalent to building a route using configuration properties but allows us to have full control of all aspects of the test route: Finally, with those beans now part of a @TestConfiguration, we can inject them into the actual test, together with a WebTestClient. We use constructor injection to get an instance of this factory, and in apply(), we delegate to it the task of creating a GatewayFilter instance. The following example configures a PreserveHostHeader GatewayFilter: The RequestRateLimiter GatewayFilter factory uses a RateLimiter implementation to determine if the current request is allowed to proceed. The arguments are typically listed in the order that would be needed for the shortcut configuration. Spring Cloud Gateway is API Gateway implementation by Spring Cloud team on top of Spring reactive ecosystem. For the transformer class, we pass an instance of our Scrubber, which implements the required RewriteFunction interface in its apply() method: The first argument passed to apply() is the current ServerWebExchange, which gives us access to the request processing context so far. profile to be active, or you may experience build errors. Add some Javadocs and, if you change the namespace, some XSD doc elements. Spring Cloud Gateway relies on the Netty based runtime environment provided by Spring Boot and Spring WebFlux, it is not built as a WAR package or run in a traditional Servlet container. This filter adds a timer metric named gateway.requests with the following tags: routeUri: The URI to which the API is routed. The following example configures an after route predicate: This route matches any request made after Jan 20, 2017 17:42 Mountain Time (Denver). Spring Cloud Gateway aims to provide a simple, yet effective way to route to APIs and provide cross cutting concerns to them such as: security, monitoring/metrics, and resiliency. The lowercase full name of the secure header needs to be used to disable it.. It creates a new named header (toHeader), and the value is extracted out of an existing named header (fromHeader) from the incoming http request. Note that this example also demonstrates the (optional) Spring Cloud Netflix Ribbon load-balancing (defined by the lb prefix on the destination URI). A number of timeouts are associated with this handshake. Spring Cloud Gateway features: Built on Spring Framework 5, Project Reactor and Spring Boot 2.0. a circuit breaker. The Cookie route predicate factory takes two parameters, the cookie name and a regexp (which is a Java regular expression). Each item defines the name and the arguments of a given predicate. but in this article, we will specifically discuss Spring Cloud Gateway - a reactive Gateway built upon Project Reactor, Spring WebFlux, and Spring Boot 2.0.. First, we will start with an introduction of Spring Cloud Gateway and . This applies the filter to all requests. The status parameter should be a 300 series redirect HTTP code, such as 301. following command: The generated eclipse projects can be imported by selecting import existing projects author credit if we do. NEVER_STRIP: The version is not stripped, even if the original request path contains no version. If using IntelliJ, you can use the We wont use it here, but its good to know we have this capability. Add yourself as an @author to the .java files that you modify substantially (more Here, well assume that payloads are relatively small, so we dont have to worry about the memory requirements to store the received object. The SaveSession GatewayFilter factory forces a WebSession::save operation before forwarding the call downstream. For more information on circuit breakers and the gateway see the Spring Cloud CircuitBreaker Factory section. The projects that require middleware (i.e. As usual, all code is available over on GitHub. The following MVC example proxies a request to /test downstream to a remote server: The following example does the same thing with Webflux: Convenience methods on the ProxyExchange enable the handler method to discover and enhance the URI path of the incoming request. So, if the downstream server responded with a X-Request-Red:1234, this would be replaced with X-Request-Red:Blue, which is what the downstream service would receive. Other IDEs and tools The name and argument names will be listed as code in the first sentance or two of the each section. This is the number of tokens the token bucket can hold. When a request matches a route, the filtering web handler adds all instances of GlobalFilter and all route-specific instances of GatewayFilter to a filter chain. The following example configures a path route predicate: This route matches if the request path was, for example: /red/1 or /red/blue or /blue/green. This uses Java regular expressions for a flexible way to rewrite the request path. The Reactor Netty HttpClient and HttpServer can have wiretap enabled. Are you sure you want to create this branch? The following example shows what this looks like: To enable Reactor Netty access logs, set -Dreactor.netty.http.server.accessLogEnabled=true. httpStatusCode: The HTTP Status of the request returned to the client. The following example configures a between route predicate: This route matches any request made after Jan 20, 2017 17:42 Mountain Time (Denver) and before Jan 21, 2017 17:42 Mountain Time (Denver). Route: The basic building block of the gateway. Websocket Sample. Import the spring-cloud-build-tools/src/main/resources/intellij/Intellij_Spring_Boot_Java_Conventions.xml file. If you are routing to an HTTPS backend, you can configure the gateway to trust all downstream certificates with the following configuration: Using an insecure trust manager is not suitable for production. (defaults to ${basedir}, i.e. The redis-rate-limiter.requestedTokens property is how many tokens a request costs. At startup, Spring looks for any @Component-annotated class that implements this interface. If routing to a https backend then the Gateway can be configured to trust all downstream certificates with the following configuration: application.yml. The previous sample defines the Cookie Route Predicate Factory with two arguments, the cookie name, mycookie and the value to match mycookievalue. You can load-balance websockets by prefixing the URI with lb, such as lb:ws://serviceid. This approach is vulnerable to spoofing, as a malicious client could set an initial value for the X-Forwarded-For, which would be accepted by the resolver. other target branch in the main project). m2eclipse to use the right profile for the projects. Displays information about a particular route. status: The HTTP status of the request returned to the client. The default is http|https|ftp|ftps. Retrieving Information about a Particular Route, 15.6. The following example configures an AddRequestParameter GatewayFilter that uses a variable: The AddResponseHeader GatewayFilter Factory takes a name and value parameter. GatewaySampleApplication.java, 4. HttpHeadersFilters are applied to requests before sending them downstream, such as in the NettyRoutingFilter. If it is not provided, the value of the Host request header is used. Spring Cloud Gateway aims to provide a simple, yet effective way to route to APIs and provide cross cutting concerns to them such as: security, monitoring/metrics, and resiliency. The following listing configures a SetRequestHost GatewayFilter: The SetRequestHost GatewayFilter factory replaces the value of the host header with example.org. as the separator. src/main/asciidoc. Spring Cloud Gateway aims to provide a simple, yet effective way to route to APIs and provide cross cutting concerns to them such as: security, monitoring/metrics, and resiliency. Typically, there will be a name key and an args key. The headers with the exception type, message and (if available) root cause exception type and message are added to that request by the FallbackHeaders filter. The following examples show how to set up global pre and post filters, respectively: Spring Cloud Gateway provides a utility object called ProxyExchange. It users the Host header, scheme, port and path of the current request to create the various headers. 2023 VMware, Inc. or its affiliates. a modified file in the correct place. the root of the project). The following listing configures a Retry GatewayFilter: When the request size is greater than the permissible limit, the RequestSize GatewayFilter factory can restrict a request from reaching the downstream service. Just commit it and push the change. *) and the replacement /${remaining}. The predicates defined by RouteDefinitionLocator beans are combined using logical and. if you are fixing an existing issue please add Fixes gh-XXXX at the end of the commit The following table describes the structure of each element (each is a route) of the response: The GatewayFilter factories applied to the route. The following example configures CORS: In the preceding example, CORS requests are allowed from requests that originate from docs.spring.io for all GET requested paths. name can contain a space-separated list of header names. This uses the URI templates from Spring Framework. There are convenience methods that you can use to mark an exchange as routed When using the retry filter with any HTTP method with a body, the body will be cached and the gateway will become memory constrained. Fixed a classcast for gateway observation; https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/master/spring-cloud-build-tools/src/main/resources/checkstyle.xml, https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/master/spring-cloud-build-tools/src/main/resources/checkstyle-header.txt, https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/master/spring-cloud-build-tools/src/checkstyle/checkstyle-suppressions.xml, You can also install Maven (>=3.3.3) yourself and run the, Be aware that you might need to increase the amount of memory Cloud Build project. The RequestRateLimiter is not configurable with the "shortcut" notation. (There is also an experimental WebClientHttpRoutingFilter that performs the same function but does not require Netty. Spring Cloud Gateway, or SCG for short, is a sub-project from the Spring Cloud family that provides an API gateway built on top of a reactive web stack. To change the default values, set the appropriate property in the spring.cloud.gateway.filter.secure-headers namespace. connect-timeout must be specified in milliseconds. This project adheres to the Contributor Covenant code of SetResponseHeader is aware of URI variables used to match a path or host. youre working on spring-cloud-contract. First-class support is provided for sensitive headers (by default, cookie and authorization), which are not passed downstream, and for proxy (x-forwarded-*) headers. There was a problem preparing your codespace, please try again. The MapRequestHeader GatewayFilter factory takes fromHeader and toHeader parameters. 2. If maxBackoff is configured, the maximum backoff applied is limited to maxBackoff. To retrieve the GatewayFilter factories applied to routes, make a GET request to /actuator/gateway/routefilters. The most notable files under the module are: Checkstyle rules are disabled by default. The resulting response is similar to the following: The following table describes the structure of the response: The collection of route predicates. that on it will try to build asciidoc sources from connect-timeout must be specified in milliseconds. Spring Tools Suite or The following loggers may contain valuable troubleshooting information at the DEBUG and TRACE levels: org.springframework.boot.autoconfigure.web. Instead, well use JDKs little-known HttpServer class, which implements a simple HTTP server. For more detailed examples of how to use any of the following filters, take a look at the. The following listing configures a RemoveRequestHeader GatewayFilter: This removes the X-Request-Foo header before it is sent downstream. The following example configures a Spring Cloud CircuitBreaker GatewayFilter: To configure the circuit breaker, see the configuration for the underlying circuit breaker implementation you are using. By using the fluent Java API, you can use the and(), or(), and negate() operators on the Predicate class. The args key is a map of key value pairs to configure the predicate or filter. The following listing defines a set of default filters: The GlobalFilter interface has the same signature as GatewayFilter. Removes an existing route from the gateway. Spring Cloud uses Maven for most build-related activities, and you The following listing configures a SetResponseHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. A route is matched if the aggregate . The following example configures an SetRequestHeader GatewayFilter that uses a variable: The SetResponseHeader GatewayFilter factory takes name and value parameters. Let's discuss each of those cases in more detail. When combined with setting the reactor.netty log level to DEBUG or TRACE, it enables the logging of information, such as headers and bodies sent and received across the wire. Java, Java SE, Java EE, and OpenJDK are trademarks of Oracle and/or its affiliates. It creates a new URI, based off of the request URI but updated with the URI attribute of the Route object. In this tutorial, we'll look at how we use Spring Cloud Gateway to inspect and/or modify the response body before sending it back to a client. The following example configures /actuator/gateway/routes: This feature is enabled by default. The RemoveRequestParameter GatewayFilter factory takes a name parameter. 1. These metrics are then available to be scraped from /actuator/metrics/gateway.requests and can be easily integrated with Prometheus to create a Grafana dashboard. Appending multiple headers can be controlled by the following boolean properties (defaults to true): spring.cloud.gateway.x-forwarded.for-append, spring.cloud.gateway.x-forwarded.host-append, spring.cloud.gateway.x-forwarded.port-append, spring.cloud.gateway.x-forwarded.proto-append, spring.cloud.gateway.x-forwarded.prefix-append. The filter takes a maxSize parameter. Spring Cloud Gateway requires the Netty runtime provided by Spring Boot and Spring Webflux. It comprises of . This predicate matches cookies that have the given name and whose values match the regular expression. There, youll have to define where the checkstyle rules should be picked from. Predicate: This is a Java 8 Function Predicate. The resulting response is similar to the following: The response contains the details of all the routes defined in the gateway. Predicates and filters are specific to routes. In future milestone releases, there will be some KeyResolver implementations. With that in mind, well name our factory ScrubResponseGatewayFilterFactory. Bootstrap your application with Spring Initializr. This predicates matches the Host header that matches the pattern. Spring Cloud Gateway. The key point here is to use the apply() method variant that, instead of taking a configuration object, expects a Consumer for the configuration. Its advisable to also install the Assertions2Assertj to automatically convert the JUnit assertions. Please point it to the Spring Cloud Builds, spring-cloud-build-tools/src/checkstyle/checkstyle-suppressions.xml file either in your cloned repo or via the https://raw.githubusercontent.com/spring-cloud/spring-cloud-build/master/spring-cloud-build-tools/src/checkstyle/checkstyle-suppressions.xml URL. It is added to the ServerWebExchange as the ServerWebExchangeUtils.CIRCUITBREAKER_EXECUTION_EXCEPTION_ATTR attribute that can be used when handling the fallback within the gateway application. This lets you match on anything from the HTTP request, such as headers or parameters. It must be a Java System Property, not a Spring Boot property. To delete a route, make a DELETE request to /gateway/routes/{id_route_to_delete}. given the ability to merge pull requests. If the fallback is called, the request is forwarded to the controller matched by the URI. The following example configures a SaveSession GatewayFilter: If you integrate Spring Security with Spring Session and want to ensure security details have been forwarded to the remote process, this is critical. Those values are then available for use by GatewayFilter factories. The response is put in the ServerWebExchangeUtils.CLIENT_RESPONSE_ATTR exchange attribute for use in a later filter. The Path Route Predicate Factory takes two parameters: a list of Spring PathMatcher patterns and an optional flag called matchOptionalTrailingSeparator. The gateway maintains a client pool that it uses to route to backends. Introduction. Spring Cloud Gateway as an OAuth 2.0 Client. 1. in the project). This predicate matches requests that happen before the specified datetime. There are many gateway solutions available such as Zuul, Linkerd, Nginx, etc. So, now that we know the contract for a rewrite function, lets finally implement our scrubber logic. AS_IN_REQUEST The version is stripped only if the original request path contains no version. The input type is a Spring Framework ServerWebExchange. To be remotely accessible, the endpoint has to be enabled and exposed over HTTP or JMX in the application properties. The SecureHeaders GatewayFilter factory adds a number of headers to the response, per the recommendation made in this blog post. Go to File Settings Editor Inspections. Support for all goodies from the Spring Cloud ecosystem (discovery, configuration, etc.) The RemoteAddr route predicate factory takes a list (min size 1) of sources, which are CIDR-notation (IPv4 or IPv6) strings, such as 192.168.0.1/16 (where 192.168.0.1 is an IP address and 16 is a subnet mask). This project provides an API Gateway built on top of the Spring Ecosystem, including: Spring 6, Spring Boot 3 and Project Reactor. 1.
