You can combine multiple route predicate factories with logical and statements. Both offer the same possibilities. which are java ZonedDateTime objects. It creates a new named header (toHeader), and the value is extracted out of an existing named header (fromHeader) from the incoming http request. The accepted values are RETAIN_FIRST (default), RETAIN_LAST, and RETAIN_UNIQUE. SetResponseHeader is aware of URI variables used to match a path or host. This can be used with reverse proxies such as load balancers or web application firewalls where By default, the gateway defines a single predicate and filter for routes created with a DiscoveryClient. When using the retry filter with any HTTP method with a body, the body will be cached and the gateway will become memory constrained. We've already covered its basic usage in earlier tutorials, so we won't get into those aspects here. For the external controller/handler scenario, headers can be added with exception details. You signed in with another tab or window. The following listing configures a SetRequestHostHeader GatewayFilter: The SetRequestHostHeader GatewayFilter factory replaces the value of the host header with example.org. public RouteLocator customRouteLocator(RouteLocatorBuilder routeBuilder){ status codes that if returned will cause the circuit breaker to be tripped. So a request to /hello is sent to /mypath/hello. 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. The SetRequestHeader GatewayFilter factory takes name and value parameters. However, you can customize this TrustManager by creating a bean of type GrpcSslConfigurer: This filter allows caching the response body and headers to follow these rules: It caches the response only for one of the following status codes: HTTP 200 (OK), HTTP 206 (Partial Content), or HTTP 301 (Moved Permanently). 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. 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]. aws api gateway parameter mapping. Any otherway is there apart from blocking call? The following listing configures a ReactiveLoadBalancerClientFilter: If there is a Route object in the ServerWebExchangeUtils.GATEWAY_ROUTE_ATTR exchange attribute, the RouteToRequestUrlFilter runs. The mapper is a Function that takes the incoming ResponseEntity and converts it to an outgoing one. Note that this example also demonstrates the (optional) Spring Cloud LoadBalancer load-balancing (defined by the lb prefix on the destination URI). The following table below summarizes the Spring Cloud Gateway actuator endpoints (note that each endpoint has /actuator/gateway as the base-path): Displays the list of global filters applied to the routes. The KeyResolver is a simple one that gets the user request parameter You can add headers to the downstream response by using the header() methods on ProxyExchange. There are two ways to configure predicates and filters: shortcuts and fully expanded arguments. You can find more information on doing so in the FallbackHeaders GatewayFilter Factory section. 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 Support for all goodies from the Spring Cloud ecosystem (discovery, configuration, etc.) Zuul profile. You can use the ModifyRequestBody filter to modify the request body before it is sent downstream by the gateway. The text was updated successfully, but these errors were encountered: Can you provide a complete, minimal, verifiable sample that reproduces the problem? We do this already It provides a convenient method to apply a transformation to JSON body content by deleting attributes from it. response-timeout must be specified as a java.time.Duration. The resulting response is similar to the following: The response contains the details of the global filters that are in place. By using the fluent Java API, you can use the and(), or(), and negate() operators on the Predicate class. The following listing configures a SetResponseHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. The Between route predicate factory takes two parameters, datetime1 and datetime2 The body is cached in a request attribute defined by. It can be used as API gateway in microservice architecture and supports dynamic routing and filtering functions. In case of the request being forwarded to fallback, the Spring Cloud CircuitBreaker Gateway filter also provides the Throwable that has caused it. This vulnerability is known as HTTP Response Splitting. It accepts the first parameter to override the time to expire a cache entry (expressed in s for seconds, m for minutes, and h for hours) and a second parameter to set the maximum size of the cache to evict entries for this route (KB, MB, or GB). This predicates matches the Host header that matches the pattern. I too was experiencing the UnsupportedOperationException when I added a post filter to an existing global filter which had an order that caused the post filter to action to occur after the response had been sent. The ForwardRoutingFilter looks for a URI in the exchange attribute ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. A Token Relay is where an OAuth2 consumer acts as a Client and Modifying the Way Remote Addresses Are Resolved, 5.12. The RewriteResponseHeader GatewayFilter factory takes name, regexp, and replacement parameters. The unmodified original URL is appended to the list in the ServerWebExchangeUtils.GATEWAY_ORIGINAL_REQUEST_URL_ATTR attribute. It does not work in a traditional Servlet Container or when built as a WAR. The earlier configuration examples all use a shortcut notation that uses positional arguments rather than named ones. The /gateway actuator endpoint lets you monitor and interact with a Spring Cloud Gateway application. Spring Cloud Gateway Encryption/Decryption of Request/Response | by Sumant Rana | Level Up Coding Write Sign up Sign In 500 Apologies, but something went wrong on our end. SpringCloud Gateway After Before Between Cookie Header Host Method Path Query RemoteAddr Weight 5.1 Path spring: application: name: gateway-server cloud: gateway: routes: - id: aaa uri: http://localhost:8001 predicates: - Path=/product/** - id: bbb uri: http://localhost:8002 predicates: - Path=/order/** 5.2 Query The Before route predicate factory takes one parameter, a datetime (which is a java ZonedDateTime). The redis-rate-limiter.replenishRate property defines how many requests per second to allow (without any dropped requests). To delete a route, make a DELETE request to /gateway/routes/{id_route_to_delete}. The following example configures an AddRequestParameter GatewayFilter that uses a variable: The AddResponseHeader GatewayFilter Factory takes a name and value parameter. The HTTP Cache-Control header allows caching (that means it does not have any of the following values: no-store present in the request and no-store or private present in the response). regexp, so green and greet would match. Note that the $ should be replaced with $\ because of the YAML specification. 25Modify Response Body GatewayFilter Factory; Download ZIP. It takes the stripVersionMode, locationHeaderName, hostValue, and protocolsRegex parameters. .uri("http://someuri") In a new folder, download and extract a new Spring Cloud Gateway project using start.spring.io(and HTTPie) as follows. If maxBackoff is configured, the maximum backoff applied is limited to maxBackoff. The request returns a 200 without a response body. 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. From the drop down, choose Mapping template and copy and paste the mapping template text below into the Template input box. This filter works only with HTTP (including HTTPS) requests. The redis-rate-limiter.requestedTokens property is how many tokens a request costs. If the URI has a scheme prefix, such as lb:ws://serviceid, the lb scheme is stripped from the URI and placed in the ServerWebExchangeUtils.GATEWAY_SCHEME_PREFIX_ATTR for use later in the filter chain. This route matches if the request has a Host header with a value of www.somehost.org or beta.somehost.org or www.anotherhost.org. The following example configures /actuator/gateway/routes: This feature is enabled by default. The hostValue parameter, if provided, is used to replace the host:port portion of the response Location header. {githubmaster}/src/main/java/org/springframework/cloud/gateway/security/TokenRelayGatewayFilterFactory.java[filter] It requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. None of the prior documentation applies to what follows. If the URL has a forward scheme (such as forward:///localendpoint), it uses the Spring DispatcherHandler to handle the request. The default predicate is a path predicate defined with the pattern /serviceId/**, where serviceId is The following example configures a before route predicate: This route matches any request made before Jan 20, 2017 17:42 Mountain Time (Denver). The name and argument names are listed as code in the first sentence or two of each section. This is the full configuration of the shortcut configuration of the Cookie predicate shown above. The following example configures an RemoveJsonAttributesResponseBody GatewayFilter that uses the optional last parameter: This removes attributes "id" and "color" from the JSON content body at any level. reverse proxies. For more detailed examples of how to use any of the following filters, take a look at the. Like in the case of global configuration, the properties belong to Spring Framework CorsConfiguration. In some cases you might want to trip a circuit breaker based on the status code URI variables may be used in the value and are expanded at runtime. 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. For example, you might want to extract the trailing elements of a path to pass them downstream: All the features of Spring MVC and Webflux are available to gateway handler methods. The default is http|https|ftp|ftps. The following properties are available: To disable the default values set the spring.cloud.gateway.filter.secure-headers.disable property with comma-separated values. If the input header does not exist, the filter has no impact. To configure per-route timeouts: Here, you can modify requests and responses before or after sending the downstream request. Server. The Path Route Predicate Factory takes two parameters: a list of Spring PathMatcher patterns and an optional flag called matchTrailingSlash (defaults to true). org.springframework.cloud.gateway.filter.factory.rewrite.ModifyResponseBodyGatewayFilterFactory body gzipchunkedHTTP Filter MonoFluxtry catch .just (xxx).doOnError () 2.2 So, if the downstream server responded with X-Response-Red:1234, it will be replaced with X-Response-Red:Blue, which is what the gateway client would receive. Post global filters are usually used in spring cloud gateway to perform operations on response like adding some headers or modifying response body or response status etc. Then, by default, the gateway metrics filter runs as long as the spring.cloud.gateway.metrics.enabled property is not set to false. This is the number of tokens the token bucket can hold. It creates a new URI, based off of the request URI but updated with the URI attribute of the Route object. 1. Those values are then available for use by GatewayFilter factories. Spring Cloud Gateway 4.0.3 This project provides an API Gateway built on top of the Spring Ecosystem, including: Spring 6, Spring Boot 3 and Project Reactor. 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 . HttpHeadersFilters are applied to the requests before sending them downstream, such as in the NettyRoutingFilter. If youre using load-balanced routes, you need to explicitly define your. A steady rate is accomplished by setting the same value in replenishRate and burstCapacity. httpMethod: The HTTP method used for the request. Likewise to the RedisRateLimiter Filter Factory it requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. Standard policies to change default 3scale APIcast behavior 3scale provides built-in, standard policies that are units of functionality that modify how APIcast processes requests and responses. extracts an access token from the currently authenticated user, forwards the incoming token to outgoing resource requests. Configuring Predicates and Filters For, 15.4. 4.1. In subsequent calls, this value is recalculated with the number of seconds left until the response expires. *) and the replacement /${remaining}. 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. Here is a link to someone asking about ordered filters that may provide more insight: #1341. It should be available as a GitHub (or similar) project or attached to this issue as a zip file. Spring Cloud has it's own way of defining Feign clients, it's done with Spring MVC annotations. Httpbin.org - a website and diagnosis tool which converts Http GET request data into a JSON response; Step 1: Create a project. returned from the route it wraps. CircuitBreaker also supports URI variables in the fallbackUri. To see the list of all Spring Cloud Gateway related configuration properties, see the appendix. Let's simplify this scenario. Writing Custom GatewayFilter Factories, 17.2.1. 1050. The gateway maintains a client pool that it uses to route to backends. 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). The following example configures an AddResponseHeader GatewayFilter that uses a variable: The Spring Cloud CircuitBreaker GatewayFilter factory uses the Spring Cloud CircuitBreaker APIs to wrap Gateway routes in The following listing configures a RewriteLocationResponseHeader GatewayFilter: For example, for a request of POST api.example.com/some/object/name, the Location response header value of object-service.prod.example.net/v2/some/object/id is rewritten as api.example.com/some/object/id. to the exchange attributes. In addition, through the spring.cloud.gateway.metrics.tags.path.enabled property (by default, false), you can activate an extra metric with the path tag: These metrics are then available to be scraped from /actuator/metrics/spring.cloud.gateway.requests and can be easily integrated with Prometheus to create a Grafana dashboard. For example, you can match on the path segment of the URL or the HTTP method of the request. Response data is not cached if Cache-Control header does not allow it (no-store present in the request or no-store or private present in the response). #{@myRateLimiter} is a SpEL expression that references a bean with named myRateLimiter. It supports basic downstream HTTP exchanges through methods that mirror the HTTP verbs. Since 4.0.0, Spring Cloud Gateway supports Spring AOT transformations and native images. Value 3.9. This filter also implements the automatic calculation of the max-age value in the HTTP Cache-Control header. How to modify spring cloud gateway response headers, https://github.com/spring-cloud/spring-cloud-gateway/files/3244970/code.txt, https://github.com/spring-cloud/spring-cloud-gateway/blob/master/spring-cloud-gateway-core/src/main/java/org/springframework/cloud/gateway/filter/factory/SetResponseHeaderGatewayFilterFactory.java. While a Gateway is running you can use kubectl scale to modify the number of replicas. Spring Cloud Gateway matches routes as part of the Spring WebFlux HandlerMapping infrastructure. Note that the null value is due to an incomplete implementation of the endpoint controller, because it tries to set the order of the object in the filter chain, which does not apply to a GatewayFilter factory object. If you would like us to look at this issue, please provide the requested information and we will re-open the issue. statuses: The HTTP status codes that should be retried, represented by using org.springframework.http.HttpStatus. The AddRequestHeader GatewayFilter factory takes a name and value parameter. status codes you want to trip the circuit breaker you can either use an integer with the status code By clicking Sign up for GitHub, you agree to our terms of service and It is the name of the header to be removed. You can load-balance websockets by prefixing the URI with lb, such as lb:ws://serviceid. NOTE: This is not recommended for production. Embed. A per-route response-timeout with a negative value will disable the global response-timeout value. The following listing configures a RemoveRequestHeader GatewayFilter: This removes the X-Request-Foo header before it is sent downstream. The RemoveRequestParameter GatewayFilter factory takes a name parameter. return r.host("*.somehost.org").and().path("/somepath") Spring Cloud Gateway offers two RouteDefinitionRepository implementations. The Method Route Predicate Factory takes a methods argument which is one or more parameters: the HTTP methods to match. Removes an existing route from the gateway. To retrieve information about a single route, make a GET request to /actuator/gateway/routes/{id} (for example, /actuator/gateway/routes/first_route). In order to modify APIcast behavior with custom policies, you must do the following: Add custom policies to APIcast Define a policy chain that configures APIcast policies Add the policy chain to APIcast 4.1. For a full working sample see this project. /resource). Since the request can be read only once, we need to cache the request body. The RequestRateLimiter is not configurable with the "shortcut" notation. The following two examples are equivalent: For some usages of the gateway, properties are adequate, but some production use cases benefit from loading configuration from an external source, such as a database. Created 6 years ago. You can configure these timeouts can be configured (defaults shown) as follows: Configuration for Spring Cloud Gateway is driven by a collection of RouteDefinitionLocator instances. The following listing configures a SetRequestHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. This is the value of the Location header. If Spring Cloud Gateway is, for example only accessible through HAProxy, then a value of 1 should be used. 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). (There is also an experimental WebClientHttpRoutingFilter that performs the same function but does not require Netty. After the proxy request is made, the post filter logic is run. Add a Header for the original response, configuration example: spring: cloud: gateway: routes: - id: add_response_header_route uri: https://example.org filters: - AddResponseHeader=X-Response-Foo, Bar. The stripVersionMode parameter has the following possible values: NEVER_STRIP, AS_IN_REQUEST (default), and ALWAYS_STRIP. The parts parameter indicates the number of parts in the path to strip from the request before sending it downstream. In configuration, you can reference the bean by name using SpEL. essentially skipping the filter. 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 SaveSession GatewayFilter factory forces a WebSession::save operation before forwarding the call downstream. To use the ProxyExchange, include the right module in your classpath (either spring-cloud-gateway-mvc or spring-cloud-gateway-webflux). 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 args key is a map of key value pairs to configure the predicate or filter. The following diagram provides a high-level overview of how Spring Cloud Gateway works: Clients make requests to Spring Cloud Gateway. However, you can also reroute the request to a controller or handler in an external application, as follows: In this example, there is no fallback endpoint or handler in the gateway application. It is the name of the header to be removed. In future milestone releases, there will be some KeyResolver implementations. 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. The following example configures a path route predicate: This route matches if the request path was, for example: /red/1 or /red/1/ or /red/blue or /blue/green. Most examples below use the shortcut way. responseCode; responseHeaderTransformations; responseMessage; type; . Route filters are scoped to a particular route. The following listing configures a Retry GatewayFilter: A simplified "shortcut" notation can be added with a single status and method. To add a filter and apply it to all routes, you can use spring.cloud.gateway.default-filters. You must use $\ to mean $ because of the YAML specification. Generally, it will put the identity information into the request header and will not modify the content of the request and response. To configure Global http timeouts: The lowercase full name of the secure header needs to be used to disable it.. The following example configures a PrefixPath GatewayFilter: This prefixes /mypath to the path of all matching requests. The gateway can listen for requests on HTTPS by following the usual Spring server configuration. The ReactiveLoadBalancerClientFilter looks for a URI in the exchange attribute named ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. The RemoveRequestHeader GatewayFilter factory takes a name parameter. There should be no reason why a filter cannot modify a response header. return routeBuilder.routes() It uses the Host header, scheme, port and path of the current request to create the various headers. The XForwarded Headers Filter creates various X-Forwarded-* headers to send to the downstream service. This may not match the actual client IP address if Spring Cloud Gateway sits behind a proxy layer. Currently, only forward: schemed URIs are supported. The following example configures a cookie route predicate factory: This route matches requests that have a cookie named chocolate whose value matches the ch.p regular expression. Fully expanded arguments appear more like standard yaml configuration with name/value pairs. as the separator. This metric will be available from /actuator/metrics/spring.cloud.gateway.routes.count. The following defaults are configured for Retry filter, if enabled: exceptions: IOException and TimeoutException. You can configure the gateway to create routes based on services registered with a DiscoveryClient compatible service registry. pass the authentication token downstream to the services (in this case In order to share Routes across a cluster of Spring Cloud Gateway instances, RedisRouteDefinitionRepository can be used. It is possible to create a gateway filter named without the. So, if the downstream server responded with X-Request-Red:1234, it will be replaced with X-Request-Red:Blue, which is what the downstream service would receive. 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. URI variables may be used in the value and will be expanded at runtime.
