name can contain a space-separated list of header names. Removes an existing route from the gateway. This type of Repository is not suited to populate Routes across multiple Gateway instances. 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). The path part of the request URL is overridden with the path in the forward URL. The XForwarded Remote Addr 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). If maxBackoff is configured, the maximum backoff applied is limited to maxBackoff. The KeyResolver is a simple one that gets the user request parameter The filter takes a maxSize parameter. Retrieving the Routes Defined in the Gateway, 15.5. Spring Cloud supports Resilience4J out of the box. it is proxying. This is the value of the Location header. This may not match the actual client IP address if Spring Cloud Gateway sits behind a proxy layer. Add a response header named X-Request-Foo with a value of Bar to the original response. AddRequestHeader is aware of the URI variables used to match a path or host. The gateway can listen for requests on HTTPS by following the usual Spring server configuration. The Retry GatewayFilter factory supports the following parameters: retries: The number of retries that should be attempted. (There is also an experimental WebClientWriteResponseFilter that performs the same function but does not require Netty.). You can configure the logging system to have a separate access log file. The Gateway is defined with a number of routes, each with Predicates to match the request to the route. Additionally, to set a multi-valued header, use the header name multiple times like AddRequestHeadersIfNotPresent=X-Request-Color-1:blue,X-Request-Color-1:green. 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. If the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a ws or wss scheme, the websocket routing filter runs. httpStatusCode: The HTTP Status of the request returned to the client. 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 . The following example configures a before route predicate: This route matches any request made before Jan 20, 2017 17:42 Mountain Time (Denver). backoff: The configured exponential backoff for the retries. The mapper is a Function that takes the incoming ResponseEntity and converts it to an outgoing one. It creates a new URI, based off of the request URI but updated with the URI attribute of the Route object. The following example configures an AddRequestHeadersIfNotPresent GatewayFilter that uses a variable: The AddRequestParameter GatewayFilter Factory takes a name and value parameter. It should be available as a GitHub (or similar) project or attached to this issue as a zip file. In this situation, the SetRequestHostHeader GatewayFilter factory can replace the existing host header with a specified value. 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. Route filters allow the modification of the incoming HTTP request or outgoing HTTP response in some manner. Spring Cloud Gateway can forward OAuth2 access tokens downstream to the services 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 listing configures a SetResponseHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. After the proxy request is made, the post filter logic is run. It may be the integer value 404 or the string representation of the enumeration: NOT_FOUND. If the new named header already exists, its values are augmented with the new values. Each item defines the name and the arguments of a given predicate. This lets you match on anything from the HTTP request, such as headers or parameters. The RemoveRequestParameter GatewayFilter factory takes a name parameter. if you intend to modify a JSON response body prior to returning to the client, the above gist will not work (i know because i tried). It also allows you to pass multi-value headers in the API response to implement things like sending multiple Set-Cookie headers. It requires the use of the spring-boot-starter-data-redis-reactive Spring Boot starter. 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. InMemoryRouteDefinitionRepository which only lives within the memory of one Gateway instance. privacy statement. responseCode; responseHeaderTransformations; responseMessage; type; . This strips the service ID from the path before the request is sent downstream. The datetime2 parameter must be after datetime1. 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. }) Naming Custom Filters And References In Configuration, 18. To change the default values, set the appropriate property in the spring.cloud.gateway.filter.secure-headers namespace. Tripping The Circuit Breaker On Status Codes, 12.4.1. This predicate extracts the URI template variables (such as sub, 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. status codes that if returned will cause the circuit breaker to be tripped. Modifying the request body is a common requirement. The predicates defined by RouteDefinitionLocator beans are combined using logical and. HttpHeadersFilters are applied to the requests before sending them downstream, such as in the NettyRoutingFilter. reverse proxies. To delete a route, make a DELETE request to /gateway/routes/{id_route_to_delete}. The ServerHttpResponse instance is used to . Sign up for a free GitHub account to open an issue and contact its maintainers and the community. It must be a Java System Property, not a Spring Boot property. When setting the This combined filter chain is sorted by the org.springframework.core.Ordered interface, which you can set by implementing the getOrder() method. I think i have to go for a blocking call here. GitHub Gist: instantly share code, notes, and snippets. For each factory there is a string representation of the corresponding object (for example, [[emailprotected] configClass = Object]). In this case, the rate limiter needs to be allowed some time between bursts (according to replenishRate), as two consecutive bursts results in dropped requests (HTTP 429 - Too Many Requests). It is possible to create a gateway filter named without the. 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. It is the permissible size limit of the request defined in bytes. This predicate matches requests that happen after datetime1 and before datetime2. response Header Transformations: . If the URL has a forward scheme (such as forward:///localendpoint), it uses the Spring DispatcherHandler to handle the request. Fork 3. The RequestRateLimiter is not configurable with the "shortcut" notation. . By default, the RemoteAddr route predicate factory uses the remote address from the incoming request. You can configure the gateway to create routes based on services registered with a DiscoveryClient compatible service registry. 2016-10-05: 4.3: CVE-2016-6426 CISCO This predicates matches the Host header that matches the pattern. The ReactiveLoadBalancerClientFilter looks for a URI in the exchange attribute named ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. 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. The Reactor Netty HttpClient and HttpServer can have wiretap enabled. It seems the response header cannot be modifed in post filter,the following is my code,please tell me a way to solve this problem. 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. The following example configures an RemoveJsonAttributesResponseBody GatewayFilter: This removes attributes "id" and "color" from the JSON content body at root level. 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. .route("test1", r -> { When a request is made through the gateway to /json/hello, the request is transformed by using the definition provided in hello.proto, sent to com.example.grpcserver.hello.HelloService/hello, and the response back is transformed to JSON. To use the ProxyExchange, include the right module in your classpath (either spring-cloud-gateway-mvc or spring-cloud-gateway-webflux). When using the retry filter with any HTTP method with a body, the body will be cached and the gateway will become memory constrained. There are convenience methods that you can use to mark an exchange as routed It creates a new named header (toHeader), and the value is extracted out of an existing named header (fromHeader) from the incoming http request. To remove any kind of sensitive header, you should configure this filter for any routes for which you may want to do so. status codes you want to trip the circuit breaker you can either use an integer with the status code The following example shows such an errorMessage: There are certain situation when the host header may need to be overridden. If you would like us to look at this issue, please provide the requested information. 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. Then, by default, the metrics will be available as long as the property spring.cloud.gateway.metrics.enabled is set to true. You signed in with another tab or window. 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 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). You can use it inside a regular Spring web handler as a method parameter. 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 following example shows how to do so: You can route gateway routes to both HTTP and HTTPS backends. This appendix provides a list of common Spring Cloud Gateway properties and references to the underlying classes that consume them. 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. 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. A utility method (called get) is available to make access to these variables easier. By clicking Sign up for GitHub, you agree to our terms of service and . You must use $\ to mean $ because of the YAML specification. There should be no reason why a filter cannot modify a response header. Modify request body. 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. The following example configures an AddResponseHeader GatewayFilter: This adds X-Response-Red:Blue header to the downstream responses headers for all matching requests. if. The PreserveHostHeader GatewayFilter factory has no parameters. The RemoveResponseHeader GatewayFilter factory takes a name parameter. 4.1. There are two ways to configure predicates and filters: shortcuts and fully expanded arguments. The following example shows how to do so: The SetPath GatewayFilter factory takes a path template parameter. If none of these parameters are configured but the global filter is enabled, by default, it configures 5 minutes of time to live for the cached response. Spring cloud gateway response body modification. 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. application.yml. application.yml. While a Gateway is running you can use kubectl scale to modify the number of replicas. the ID of the service from the DiscoveryClient. The redis-rate-limiter.replenishRate property defines how many requests per second to allow (without any dropped requests). To add this functionality to the gateway, you need to add the TokenRelayGatewayFilterFactory like this: and it will (in addition to logging the user in and grabbing a token) The default filter is a rewrite path filter with the regex /serviceId/?(?. The earlier configuration examples all use a shortcut notation that uses positional arguments rather than named ones. For example, you can match on the path segment of the URL or the HTTP method of the request. If matchTrailingSlash is set to false, then request path /red/1/ will not be matched. This applies the filter to all requests. Policy to specify how to modify the response code, body and headers. Once a request has been marked as routed, other routing filters will not route the request again, To enable the Spring Cloud CircuitBreaker filter, you need to place spring-cloud-starter-circuitbreaker-reactor-resilience4j on the classpath. This is the full configuration of the shortcut configuration of the Cookie predicate shown above. 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). /resource). 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. Route filters are scoped to a particular route. To configure per-route timeouts: The following example configures an SetResponseHeader GatewayFilter that uses a variable: The SetStatus GatewayFilter factory takes a single parameter, status. The RemoveRequestHeader GatewayFilter factory takes a name parameter. }, 4. .filters(f -> f.addRequestHeader("header1", "header-value-1")) XForwardedRemoteAddressResolver::maxTrustedIndex takes an index that correlates to the number of trusted infrastructure running in front of Spring Cloud Gateway. The primary scenario is to use the fallbackUri to define an internal controller or handler within the gateway application. 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. This predicate matches requests that happen before the specified datetime. outcome: The outcome, as classified by HttpStatus.Series. To enable this for Spring Cloud Gateway add the following dependencies, org.springframework.boot:spring-boot-starter-oauth2-client. The default predicate is a path predicate defined with the pattern /serviceId/**, where serviceId is The default is http|https|ftp|ftps. 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. The Cookie route predicate factory takes two parameters, the cookie name and a regexp (which is a Java regular expression). In The RequestRateLimiter GatewayFilter factory uses a RateLimiter implementation to determine if the current request is allowed to proceed. It adds the Host header, scheme and port of the current request to any existing Forwarded header. extracts an access token from the currently authenticated user, The Header route predicate factory takes two parameters, the header and a regexp (which is a Java regular expression). Refresh the page, check Medium 's site status, or find something interesting to read. The Forwarded Headers Filter creates a Forwarded header to send to the downstream service. exceptions: A list of thrown exceptions that should be retried. Star 14. Displays the list of GatewayFilter factories applied to a particular route. The following properties are available: To disable the default values set the spring.cloud.gateway.filter.secure-headers.disable property with comma-separated values. ServerWebExchangeUtils.setAlreadyRouted takes a ServerWebExchange object and marks it as routed. org.springframework.cloud.gateway.filter.factory.rewrite.ModifyResponseBodyGatewayFilterFactory body gzipchunkedHTTP Filter MonoFluxtry catch .just (xxx).doOnError () 2.2 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. spring: cloud: gateway: routes: - id: add_response_header_route uri: https://example.org predicates: - Host: {segment}.myhost.org filters: - AddResponseHeader=foo,bar-{segment} Writing Custom GatewayFilter Factories, 17.2.1. This project provides an API Gateway built on top of the Spring Ecosystem, including: Spring 6, Spring Boot 3 and Project Reactor. and puts it in a request header for the downstream requests. The lowercase full name of the secure header needs to be used to disable it.. A gauge metric named spring.cloud.gateway.routes.count will be added, whose value is the number of RouteDefinitions. 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.) Options. 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. In the next tutorial of Spring Cloud Gateway Example we will implement these theories and build an application with microservice architecture using Spring Cloud Gateway and demonstrate working examples on web filters to modify request and response body. The following listing shows how to do so: A new, more verbose format has been added to Spring Cloud Gateway. 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 In a new folder, download and extract a new Spring Cloud Gateway project using start.spring.io(and HTTPie) as follows. forwards the incoming token to outgoing resource requests. 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]. The new URI is placed in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute. Generally, it will put the identity information into the request header and will not modify the content of the request and response. You can configure the SetStatus GatewayFilter to return the original HTTP status code from the proxied request in a header in the response. 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 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. The XForwarded Remote Addr Route Predicate Factory, 6.5.1. Create a ClientResponse object that will hold both the body and the headers: Then extract the body and encrypt it using the EncryptDecryptHelper class. also note that the gist doesn't take the decoders into account from upstream like here. 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). return r.host("*.somehost.org").and().path("/somepath") The following example configures a header route predicate: This route matches if the request has a header named X-Request-Id whose value matches the \d+ regular expression (that is, it has a value of one or more digits). Displays information about a particular route. Value 3.9. When communicating over HTTPS, the client initiates a TLS handshake. Future milestone versions will have RouteDefinitionLocator implementations based off of Spring Data Repositories, such as Redis, MongoDB, and Cassandra. There is an abstract class called AbstractRoutePredicateFactory which you can extend. 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. Fully expanded arguments appear more like standard yaml configuration with name/value pairs. 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 an AddRequestHeadersIfNotPresent GatewayFilter: This listing adds 2 headers X-Request-Color-1:blue and X-Request-Color-2:green to the downstream requests headers for all matching requests. Spring Cloud has it's own way of defining Feign clients, it's done with Spring MVC annotations. Typically, there will be a name key and an args key. Any otherway is there apart from blocking call? It is a Spring Boot application with Spring Cloud stuff that can make it sit between clients and their requests and multiple services, where it offers features such as predicates for shaping. 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. - thaneesh shanand Apr 16, 2018 at 1:05 Oracle Cloud Infrastructure SDK for TypeScript and JavaScript API Reference - 2.53.1. Writing Custom Route Predicate Factories, 17.2. All of these predicates match on different attributes of the HTTP request. In the example below the call consumingServiceEndpoint/users/1 will be redirected to inCaseOfFailureUseThis/users/1. Note that this example also demonstrates the (optional) Spring Cloud LoadBalancer load-balancing (defined by the lb prefix on the destination URI). Route: The basic building block of the gateway. Some situations necessitate reading the request body. #{@myKeyResolver} is a SpEL expression that references a bean named myKeyResolver. 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. It uses the Netty HttpClient to make the downstream proxy request. Want to remove the "warning cannot modify header information" error from your WordPress website? The j_spring_security_switch_user function in Cisco Unified Intelligence Center (CUIC) 8.5.4 through 9.1(1), as used in Unified Contact Center Express 10.0(1) through 11.0(1), allows remote attackers to create user accounts by visiting an unspecified web page, aka Bug IDs CSCuy75027 and CSCuy81653. A burst of 20 is allowed, but, in the next second, only 10 requests are available. It uses the Netty HttpClient to make the downstream proxy request. From the drop down, choose Mapping template and copy and paste the mapping template text below into the Template input box. Zuul profile. 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. Since 4.0.0, Spring Cloud Gateway supports Spring AOT transformations and native images. The /gateway actuator endpoint lets you monitor and interact with a Spring Cloud Gateway application. 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. 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 The weights are calculated per group. This could be useful for maintenance windows. .build(); 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). Setting this value to zero blocks all requests. For example, when we use Spring Cloud Gateway to implement the gateway, we need to implement a function: parse the JWT stored in the request header, extract the user ID in it, and then write it to the request body. The The RemoveJsonAttributesResponseBody GatewayFilter factory takes a collection of attribute names to search for, an optional last parameter from the list can be a boolean to remove the attributes just at root level (thats the default value if not present at the end of the parameter configuration, false) or recursively (true).
