ServerHttpResponse interface. The DedupeResponseHeader GatewayFilter factory takes a name parameter and an optional strategy parameter. To disable it, set the following property: This will default to true in a future release. 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. Refresh the page, check Medium 's site status, or find something interesting to read. methods: The HTTP methods that should be retried, represented by using org.springframework.http.HttpMethod. The ForwardRoutingFilter looks for a URI in the exchange attribute ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. In some cases you might want to trip a circuit breaker based on the status code A Token Relay is where an OAuth2 consumer acts as a Client and GitHub Gist: instantly share code, notes, and snippets. This filter sets a request attribute that the routing filter inspects to determine if the original host header should be sent rather than the host header determined by the HTTP client. It takes the stripVersionMode, locationHeaderName, hostValue, and protocolsRegex parameters. The following listing shows how to do so: A new, more verbose format has been added to Spring Cloud Gateway. That is not a complete working sample, it is just some code. Here is a link to someone asking about ordered filters that may provide more insight: #1341. The request returns a 200 without a response body. URI variables may be used in the value and are expanded at runtime. The filter takes the following arguments: This file can be generated using protoc and specifying the --descriptor_set_out flag: service: Fully qualified name of the service that handles the request. When communicating over HTTPS, the client initiates a TLS handshake. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Creating of individual headers can be controlled by the following boolean properties (defaults to true): spring.cloud.gateway.x-forwarded.for-enabled, spring.cloud.gateway.x-forwarded.host-enabled, spring.cloud.gateway.x-forwarded.port-enabled, spring.cloud.gateway.x-forwarded.proto-enabled, spring.cloud.gateway.x-forwarded.prefix-enabled. The following example configures a RemoveRequestParameter GatewayFilter: This will remove the red parameter before it is sent downstream. The Reactor Netty HttpClient and HttpServer can have wiretap enabled. The RewriteResponseHeader GatewayFilter factory takes name, regexp, and replacement parameters. or check if an exchange has already been routed. 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. URI variables may be used in the value and are expanded at runtime. In configuration, reference the bean by name using SpEL. The collection of filters applied to the route. Various properties can be specified inside your application.properties file, inside your application.yml file, or as command line switches. Httpbin.org - a website and diagnosis tool which converts Http GET request data into a JSON response; Step 1: Create a project. During your stay, take advantage of some of the amenities offered, including a 24 hour front desk, room service, and a gift shop. To add a filter and apply it to all routes, you can use spring.cloud.gateway.default-filters. Then, by default, the metrics will be available as long as the property spring.cloud.gateway.metrics.enabled is set to true. The following loggers may contain valuable troubleshooting information at the DEBUG and TRACE levels: org.springframework.boot.autoconfigure.web. The The JSONToGRPCFilter GatewayFilter Factory converts a JSON payload to a gRPC request. 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 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. Spring Cloud Gateway. The preceding route matches if the request contained a red query parameter whose value matched the gree. For example, to reference a filter named Something in configuration files, the filter This is similar to how AddRequestHeader works, but unlike AddRequestHeader it will do it only if the header is not already there. There are convenience methods that you can use to mark an exchange as routed In addition, you can configure this filter once by using spring.cloud.gateway.default-filters and have it applied to all routes. Future milestone versions will have RouteDefinitionLocator implementations based off of Spring Data Repositories, such as Redis, MongoDB, and Cassandra. ServerWebExchangeUtils.isAlreadyRouted takes a ServerWebExchange object and checks if it has been routed. There is an abstract class called AbstractRoutePredicateFactory which you can extend. I think i have to go for a blocking call here. The following listing configures a RedirectTo GatewayFilter: This will send a status 302 with a Location:https://acme.org header to perform a redirect. 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. 1. Fully expanded arguments appear more like standard yaml configuration with name/value pairs. Displays the list of routes defined in the gateway. .application.yml. org.springframework.cloud.gateway.filter.factory.rewrite.ModifyResponseBodyGatewayFilterFactory body gzipchunkedHTTP Filter MonoFluxtry catch .just (xxx).doOnError () 2.2 This property takes a list of filters. URI variables may be used in the value and will be expanded at runtime. The following example configures an SetResponseHeader GatewayFilter that uses a variable: The SetStatus GatewayFilter factory takes a single parameter, status. The pattern is an Ant-style pattern with . For more information on circuit breakers and the gateway see the Spring Cloud CircuitBreaker Factory section. The Method Route Predicate Factory takes a methods argument which is one or more parameters: the HTTP methods to match. Then the proxy request is made. httpMethod: The HTTP method used for the request. The gateway can listen for requests on HTTPS by following the usual Spring server configuration. It is the name of the header to be removed. The predicates defined by RouteDefinitionLocator beans are combined using logical and. You can read more about them in the. To delete a route, make a DELETE request to /gateway/routes/{id_route_to_delete}. The new URI is placed in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute. The following table describes the structure of each element (each is a route) of the response: The GatewayFilter factories applied to the route. This vulnerability is known as HTTP Response Splitting. Service 4.3. The SetRequestHeader GatewayFilter factory takes name and value parameters. The RemoveResponseHeader GatewayFilter factory takes a name parameter. The SecureHeaders GatewayFilter factory adds a number of headers to the response, per the recommendation made in this blog post. This can be used with reverse proxies such as load balancers or web application firewalls where The following listing configures a redis-rate-limiter: Rate limits below 1 request/s are accomplished by setting replenishRate to the wanted number of requests, requestedTokens to the timespan in seconds, and burstCapacity to the product of replenishRate and requestedTokens. For a production deployment, you can configure the gateway with a set of known certificates that it can trust with the following configuration: If the Spring Cloud Gateway is not provisioned with trusted certificates, the default trust store is used (which you can override by setting the javax.net.ssl.trustStore system property). privacy statement. If the information is not provided within the next 7 days this issue will be closed. This project provides an API Gateway built on top of the Spring Ecosystem, including: Spring 6, Spring Boot 3 and Project Reactor. A utility method (called get) is available to make access to these variables easier. return r.host("*.somehost.org").and().path("/somepath") The following maxTrustedIndex values yield the following remote addresses: (invalid, IllegalArgumentException during initialization). Modifying the headers is simple because we can obtain a reference to the HttpHeaders map object: exchange.getRequest () .mutate () .headers (h -> h.setAcceptLanguageAsLocales ( Collections.singletonList (requestLocale))) Copy But, on the other hand, modifying the URI is not a trivial task. Modifying the request body is a common requirement. The Header route predicate factory takes two parameters, the header and a regexp (which is a Java regular expression). For the external controller/handler scenario, headers can be added with exception details. If the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a ws or wss scheme, the websocket routing filter runs. This filter also automatically calculates the. The following example shows how to do so: You can route gateway routes to both HTTP and HTTPS backends. AddRequestHeader is aware of the URI variables used to match a path or host. The hostValue parameter, if provided, is used to replace the host:port portion of the response Location header. #{@myRateLimiter} is a SpEL expression that references a bean with named myRateLimiter. 4.1. If maxBackoff is configured, the maximum backoff applied is limited to maxBackoff. The After route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). The global CORS configuration is a map of URL patterns to Spring Framework CorsConfiguration. This filter (which configures the local response cache per route) is available only if the local response global cache is enabled. First-class support is provided for sensitive headers (by default, cookie and authorization), which are not passed downstream, and for proxy (x-forwarded-*) headers. XForwardedRemoteAddressResolver has two static constructor methods, which take different approaches to security: XForwardedRemoteAddressResolver::trustAll returns a RemoteAddressResolver that always takes the first IP address found in the X-Forwarded-For header. This handler runs the request through a filter chain that is specific to the request. Server. NOTE: This is not recommended for production. The previous sample defines the Cookie Route Predicate Factory with two arguments, the cookie name, mycookie and the value to match mycookievalue. Passing headers with Spring Cloud Feign. The redis-rate-limiter.replenishRate property defines how many requests per second to allow (without any dropped requests). To enable this, set spring.cloud.gateway.discovery.locator.enabled=true and make sure a DiscoveryClient implementation (such as Netflix Eureka, Consul, or Zookeeper) is on the classpath and enabled. AddResponseHeader is aware of URI variables used to match a path or host. Easy to extend and/or customize using standard Spring patterns The following example configures a XForwardedRemoteAddr route predicate: This route matches if the X-Forwarded-For header contains, for example, 192.168.1.10. You can configure Spring Cloud Gateway for Kubernetes to run multiple instances in High Availability as you would do with a normal Kubernetes resource. The XForwarded Headers Filter creates various X-Forwarded-* headers to send to the downstream service. In case of the request being forwarded to fallback, the Spring Cloud CircuitBreaker Gateway filter also provides the Throwable that has caused it. import static org.springframework.cloud.gateway.support.RouteMetadataUtils.CONNECT_TIMEOUT_ATTR; 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). Retrieving the Routes Defined in the Gateway, 15.5. AS_IN_REQUEST: The version is stripped only if the original request path contains no version. It uses the Netty HttpClient to make the downstream proxy request. spring.cloud.gateway.filter.local-response-cache.timeToLive Sets the time to expire a cache entry (expressed in s for seconds, m for minutes, and h for hours). If you want to customize the predicates or filters used by the DiscoveryClient routes, set spring.cloud.gateway.discovery.locator.predicates[x] and spring.cloud.gateway.discovery.locator.filters[y]. It is the name of the query parameter to be removed. }) When setting the InMemoryRouteDefinitionRepository which only lives within the memory of one Gateway instance. Writing Custom GatewayFilter Factories, 17.2.1. Because Spring-Cloud-Gateway is a responsive architecture design based on WebFlux, traditional programming ideas are not suitable for the development of Reactor Stream in the process of migrating from Zuul. It creates a new URI, based off of the request URI but updated with the URI attribute of the Route object. You can also manipulate response headers (and anything else you like in the response) by adding a mapper to the get() method (and other methods). To see the list of all Spring Cloud Gateway related configuration properties, see the appendix. aws api gateway parameter mapping. To retrieve the GatewayFilter factories applied to routes, make a GET request to /actuator/gateway/routefilters. The following example shows such an errorMessage: There are certain situation when the host header may need to be overridden. Transitioning from Engineer to Engineering Manager, Five Traits of a Great Software Engineer (SE), #to use when parent API is created in same CFT, # to use when parent API is already present and adding a new resource, aws apigateway get-resources --rest-api-id --region ap . A per-route response-timeout with a negative value will disable the global response-timeout value. The RemoteAddr Route Predicate Factory, 5.10.1. The following example configures such a fallback: The following listing does the same thing in Java: This example forwards to the /inCaseofFailureUseThis URI when the circuit breaker fallback is called. You can configure the gateway to create routes based on services registered with a DiscoveryClient compatible service registry. The lowercase full name of the secure header needs to be used to disable it.. The default list of headers that is removed comes from the IETF. The following listing configures a RemoveRequestHeader GatewayFilter: This removes the X-Request-Foo header before it is sent downstream. status codes you want to trip the circuit breaker you can either use an integer with the status code There are many caching cases on the network, but there are various Bug problems in the testing process. Generally, it will put the identity information into the request header and will not modify the content of the request and response. The default request size is set to five MB if not provided as a filter argument in the route definition. The following example configures a RemoteAddr route predicate: This route matches if the remote address of the request was, for example, 192.168.1.10. The following listing shows how to cache the request body GatewayFilter: CacheRequestBody extracts the request body and converts it to a body class (such as java.lang.String, defined in the preceding example). If you would like us to look at this issue, please provide the requested information. The Before route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). The mapper is a Function that takes the incoming ResponseEntity and converts it to an outgoing one. application.yml. The default predicate is a path predicate defined with the pattern /serviceId/**, where serviceId is This filter takes an optional keyResolver parameter and parameters specific to the rate limiter (described later in this section). To enable this kind of repository, the following property has to set to true: spring.cloud.gateway.redis-route-definition-repository.enabled The following listing shows the definition of the RouteDefinitionLocator interface: By default, a PropertiesRouteDefinitionLocator loads properties by using Spring Boots @ConfigurationProperties mechanism. Spring Cloud supports Resilience4J out of the box. The following listing defines a rate limiter that uses the KeyResolver defined in the previous listing: The RewriteLocationResponseHeader GatewayFilter factory modifies the value of the Location response header, usually to get rid of backend-specific details. Already on GitHub? Otherwise, the original value in the client request is sent. If max-age is present on the original response, the value is rewritten with the number of seconds set in the timeToLive configuration parameter. /resource). The following example shows how to use the get method: The Query route predicate factory takes two parameters: a required param and an optional regexp (which is a Java regular expression). GitHub spring-cloud / spring-cloud-gateway Public Notifications Fork 2.9k Star 3.9k Code Issues 337 Pull requests 39 Actions Projects Security Insights New issue How to modify spring cloud gateway response headers #1092 Closed .route("test1", r -> { Writing Custom Route Predicate Factories, 17.2. The following listing shows how to modify a request body GatewayFilter: You can use the ModifyResponseBody filter to modify the response body before it is sent back to the client. The accepted values are RETAIN_FIRST (default), RETAIN_LAST, and RETAIN_UNIQUE. The most noteworthy thing here is: ServerHttpRequest or HttpMessage interface provides a method to get the request headers HttpHeaders getHeaders(); returns a read-only instance, specifically of type ReadOnlyHttpHeaders, mentioned here more than once I wrote this blog post using Spring Cloud Gateway version Greenwich.SR1. The resulting response is similar to the following: The response contains the details of all the routes defined in the gateway. As Spring Cloud Gateway distinguishes between pre and post phases for filter logic execution (see How it Works), the filter with the highest precedence is the first in the pre-phase and the last in the post-phase. To allow for simple configuration in Java, the RouteLocatorBuilder bean includes a fluent API. keyResolver is a bean that implements the KeyResolver interface. Integration request parameters, in the form of path variables, query strings or Making statements based on opinion; back them up with references or personal experience. This uses the URI templates from Spring Framework. The following listing configures a SetRequestHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. You can use the CacheRequestBody filter to cache the request body before sending it downstream and getting the body from exchange attribute. XForwardedRemoteAddressResolver::maxTrustedIndex takes an index that correlates to the number of trusted infrastructure running in front of Spring Cloud Gateway. Spring Cloud Gateway 1AddRequestHeader GatewayFilter Factory2AddRequestParameter GatewayFilter Factory3AddResponseHeader GatewayFilter Factory4DedupeResponseHeader GatewayFilter Fa. Note that this example also demonstrates the (optional) Spring Cloud LoadBalancer load-balancing (defined by the lb prefix on the destination URI). Red Hat 3scale provides a method for adding custom policies, but does not support custom policies. You can configure the SetStatus GatewayFilter to return the original HTTP status code from the proxied request in a header in the response. Value 3.9. If You Appreciate This, You Can Consider: We are thankful for your never ending support. Have a question about this project? To include Spring Cloud Gateway in your project, use the starter with a group ID of org.springframework.cloud and an artifact ID of spring-cloud-starter-gateway. A burst of 20 is allowed, but, in the next second, only 10 requests are available. To enable this for Spring Cloud Gateway add the following dependencies, org.springframework.boot:spring-boot-starter-oauth2-client. This predicate extracts the URI template variables (such as segment, defined in the preceding example) as a map of names and values and places it in the ServerWebExchange.getAttributes() with a key defined in ServerWebExchangeUtils.URI_TEMPLATE_VARIABLES_ATTRIBUTE. This is the full configuration of the shortcut configuration of the Cookie predicate shown above. This filter adds a timer metric named spring.cloud.gateway.requests with the following tags: routeUri: The URI to which the API is routed. In subsequent calls, this value is recalculated with the number of seconds left until the response expires. let's see. 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). The By default, when a service instance cannot be found by the, Gateway supports all the LoadBalancer features. The ReactiveLoadBalancerClientFilter looks for a URI in the exchange attribute named ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. The following listing configures a RewritePath GatewayFilter: For a request path of /red/blue, this sets the path to /blue before making the downstream request. . The RemoveRequestParameter GatewayFilter factory takes a name parameter. This paper will introduce its usage in detail. A gauge metric named spring.cloud.gateway.routes.count will be added, whose value is the number of RouteDefinitions. The following example configures a KeyResolver in Java: This defines a request rate limit of 10 per user. It must be a valid Spring HttpStatus. For a full working sample see this project. *) and the replacement /${remaining}. To change this, set the spring.cloud.gateway.filter.remove-hop-by-hop.headers property to the list of header names to remove. connect-timeout must be specified in milliseconds. response Header Transformations: . In Puma (RubyGem) before 4.3.3 and 3.12.4, if an application using Puma allows untrusted input in an early-hints header, an attacker can use a carriage return character to end the header and inject malicious content, such as additional headers or an entirely new response body. }, 4. Each item defines the name and the arguments of a given predicate. Building a Simple Gateway by Using Spring MVC or Webflux, FallbackHeaders GatewayFilter Factory section, Spring Cloud CircuitBreaker Factory section, object-service.prod.example.net/v2/some/object/id, Retrieving Information about a Particular Route. The resulting response is similar to the following: The response contains the details of the global filters that are in place. Gunzenhausen (German pronunciation: [ntsnhazn] (); Bavarian: Gunzenhausn) is a town in the Weienburg-Gunzenhausen district, in Bavaria, Germany.It is situated on the river Altmhl, 19 kilometres (12 mi) northwest of Weienburg in Bayern, and 45 kilometres (28 mi) southwest of Nuremberg.Gunzenhausen is a nationally recognized recreation area. The filter takes a maxSize parameter. and puts it in a request header for the downstream requests. 1050. import static org.springframework.cloud.gateway.support.RouteMetadataUtils.RESPONSE_TIMEOUT_ATTR; @Bean The following listing configures a RequestHeaderSize GatewayFilter: This will send a status 431 if size of any request header is greater than 1000 Bytes. Configuring Predicates and Filters For, 15.4. Any otherway is there apart from blocking call? 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. By default, the gateway defines a single predicate and filter for routes created with a DiscoveryClient. Configuring Route Predicate Factories and Gateway Filter Factories, 5.10. Closing due to lack of requested feedback. return routeBuilder.routes() For each factory there is a string representation of the corresponding object (for example, [[emailprotected] configClass = Object]). AddRequestHeadersIfNotPresent also supports URI variables used to match a path or host. spring.cloud.gateway.filter.local-response-cache.size: Sets the maximum size of the cache to evict entries for this route (in KB, MB and GB). These are special filters that are conditionally applied to all routes. The following example configures a weight route predicate: This route would forward ~80% of traffic to weighthigh.org and ~20% of traffic to weighlow.org. In The following example configures an AddRequestHeader GatewayFilter: This listing adds X-Request-red:blue header to the downstream requests headers for all matching requests. Created 6 years ago. The RemoveHopByHop Headers Filter removes headers from forwarded requests. .build(); The header is added to the response if configured with the following property: The StripPrefix GatewayFilter factory takes one parameter, parts. Shortcut configuration is recognized by the filter name, followed by an equals sign (=), followed by argument values separated by commas (,). To enable RouteDefinition metrics, add spring-boot-starter-actuator as a project dependency. (There is also an experimental WebClientWriteResponseFilter that performs the same function but does not require Netty.). Removes an existing route from the gateway. The following two examples are equivalent: When the request size is greater than the permissible limit, the RequestSize GatewayFilter factory can restrict a request from reaching the downstream service. #{@myKeyResolver} is a SpEL expression that references a bean named myKeyResolver. Well occasionally send you account related emails. The following listing configures a SetResponseHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. It should be available as a GitHub (or similar) project or attached to this issue as a zip file. The following example configures an AddResponseHeader GatewayFilter: This adds X-Response-Red:Blue header to the downstream responses headers for all matching requests. The following listing configures a filter chain: To enable gateway metrics, add spring-boot-starter-actuator as a project dependency. SetRequestHeader is aware of URI variables used to match a path or host. The stripVersionMode parameter has the following possible values: NEVER_STRIP, AS_IN_REQUEST (default), and ALWAYS_STRIP. extracts an access token from the currently authenticated user, You can configure additional parameters for each route by using metadata, as follows: You could acquire all metadata properties from an exchange, as follows: Http timeouts (response and connect) can be configured for all routes and overridden for each specific route. You can configure the logging system to have a separate access log file. I suppose your issue may have been different than mine, but when I turned on trace logging I saw that my filter was executing after the response was sent and so I gave the filter a different order value that put it in the right order. The following example configures a SetPath GatewayFilter: For a request path of /red/blue, this sets the path to /blue before making the downstream request. It uses the Netty HttpClient to make the downstream proxy request. The default is http|https|ftp|ftps.
