To delete a route, make a DELETE request to /gateway/routes/{id_route_to_delete}. The following listing defines a set of default filters: The GlobalFilter interface has the same signature as GatewayFilter. to the exchange attributes. In configuration, you can reference the bean by name using SpEL. The XForwarded Headers Filter creates various X-Forwarded-* headers to send to the downstream service. The following listing configures a websocket routing filter: After the gateway has routed a ServerWebExchange, it marks that exchange as routed by adding gatewayAlreadyRouted Note that the $ should be replaced with $\ because of the YAML specification. It is possible to create a gateway filter named without the. Those values are then available for use by GatewayFilter factories. The RewritePath GatewayFilter factory takes a path regexp parameter and a replacement parameter. The text was updated successfully, but these errors were encountered: Can you provide a complete, minimal, verifiable sample that reproduces the problem? Naming Custom Filters And References In Configuration, 18. If you would like us to look at this issue, please provide the requested information and we will re-open the issue. This filter also implements the automatic calculation of the max-age value in the HTTP Cache-Control header. The unmodified original URL is appended to the list in the ServerWebExchangeUtils.GATEWAY_ORIGINAL_REQUEST_URL_ATTR attribute. The following example configures a XForwardedRemoteAddr route predicate: This route matches if the X-Forwarded-For header contains, for example, 192.168.1.10. The following example configures a RemoveRequestParameter GatewayFilter: This will remove the red parameter before it is sent downstream. To allow for simple configuration in Java, the RouteLocatorBuilder bean includes a fluent API. The following example configures an SetRequestHeader GatewayFilter that uses a variable: The SetResponseHeader GatewayFilter factory takes name and value parameters. By using the fluent Java API, you can use the and(), or(), and negate() operators on the Predicate class. The following example configures a method route predicate: This route matches if the request method was a GET or a POST. The following example configures a query route predicate: The preceding route matches if the request contained a green query parameter. The following example configures a PrefixPath GatewayFilter: This prefixes /mypath to the path of all matching requests. The following example shows how to achieve the same configuration with Java: The Weight route predicate factory takes two arguments: group and weight (an int). 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. 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 can be used with reverse proxies such as load balancers or web application firewalls where The default is http|https|ftp|ftps. 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. The following example shows what this looks like: To enable Reactor Netty access logs, set -Dreactor.netty.http.server.accessLogEnabled=true. The Header route predicate factory takes two parameters, the header and a regexp (which is a Java regular expression). 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. Spring Cloud Gateway requires the Netty runtime provided by Spring Boot and Spring Webflux. To change the default values, set the appropriate property in the spring.cloud.gateway.filter.secure-headers namespace. During your stay, take advantage of some of the amenities offered, including a 24 hour front desk, room service, and a gift shop. 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. 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. To configure Global http timeouts: The global CORS configuration is a map of URL patterns to Spring Framework CorsConfiguration. To retrieve the GatewayFilter factories applied to routes, make a GET request to /actuator/gateway/routefilters. InMemoryRouteDefinitionRepository which only lives within the memory of one Gateway instance. Spring Cloud Gateway offers two RouteDefinitionRepository implementations. Future milestone versions will have RouteDefinitionLocator implementations based off of Spring Data Repositories, such as Redis, MongoDB, and Cassandra. To be remotely accessible, the endpoint has to be enabled and exposed over HTTP or JMX in the application properties. Temporary bursts can be allowed by setting burstCapacity higher than replenishRate. If you would like us to look at this issue, please provide the requested information. Most examples below use the shortcut way. 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 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. 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 Retry GatewayFilter factory supports the following parameters: retries: The number of retries that should be attempted. application.yml. The earlier configuration examples all use a shortcut notation that uses positional arguments rather than named ones. Like in the case of global configuration, the properties belong to Spring Framework CorsConfiguration. Spring Cloud Gateway can forward OAuth2 access tokens downstream to the services extracts an access token from the currently authenticated user, ), The NettyWriteResponseFilter runs if there is a Netty HttpClientResponse in the ServerWebExchangeUtils.CLIENT_RESPONSE_ATTR exchange attribute. 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 following example configures /actuator/gateway/routes: This feature is enabled by default. The default is 'B' for bytes. That is not a complete working sample, it is just some code. 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 In subsequent calls, this value is recalculated with the number of seconds left until the response expires. 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 read more about them in the. The ForwardRoutingFilter looks for a URI in the exchange attribute ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. You can combine multiple route predicate factories with logical and statements. To change this, set the spring.cloud.gateway.filter.remove-hop-by-hop.headers property to the list of header names to remove. The following example configures a RewriteResponseHeader GatewayFilter: For a header value of /42?user=ford&password=omg!what&flag=true, it is set to /42?user=ford&password=***&flag=true after making the downstream request. The following example configures an AddRequestHeader GatewayFilter that uses a variable: The AddRequestHeadersIfNotPresent GatewayFilter factory takes a collection of name and value pairs separated by colon. 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. It takes the stripVersionMode, locationHeaderName, hostValue, and protocolsRegex parameters. 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). The PreserveHostHeader GatewayFilter factory has no parameters. See the documentation for @RequestMapping in Spring MVC for more details of those features. The first step is to create a ServerHttpResponseDecorator object and override the writeWith method. 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. To clear the routes cache, make a POST request to /actuator/gateway/refresh. or check if an exchange has already been routed. Value 3.9. For relative redirects, you should use uri: no://op as the uri of your route definition. Any otherway is there apart from blocking call? The hostValue parameter, if provided, is used to replace the host:port portion of the response Location header. It also allows you to pass multi-value headers in the API response to implement things like sending multiple Set-Cookie headers. If so, the same rules apply. The following examples show how to do so: Custom filters class names should end in GatewayFilterFactory. 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. Easy to extend and/or customize using standard Spring patterns AddRequestHeader is aware of the URI variables used to match a path or host. The resulting response is similar to the following: The following table describes the structure of the response: The collection of route predicates. In a new folder, download and extract a new Spring Cloud Gateway project using start.spring.io(and HTTPie) as follows. A route is matched if the aggregate predicate is true. A burst of 20 is allowed, but, in the next second, only 10 requests are available. The following listing configures a SetRequestHeader GatewayFilter: This GatewayFilter replaces (rather than adding) all headers with the given name. Feign is a great way to communicate between services and send data like a JSON request body, single header or multiple headers and much more. 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. This predicates matches the Host header that matches the pattern. 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 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. The stripVersionMode parameter has the following possible values: NEVER_STRIP, AS_IN_REQUEST (default), and ALWAYS_STRIP. The ReactiveLoadBalancerClientFilter looks for a URI in the exchange attribute named ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR. The RequestRateLimiter GatewayFilter factory uses a RateLimiter implementation to determine if the current request is allowed to proceed. per-route http timeouts configuration via configuration, per-route timeouts configuration using Java DSL, Example 73. The redis-rate-limiter.replenishRate property defines how many requests per second to allow (without any dropped requests). 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. It is the name of the header to be removed. Spring Cloud Gateway. Modifying the Way Remote Addresses Are Resolved, 5.12. 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). In some cases you might want to trip a circuit breaker based on the status code NEVER_STRIP: The version is not stripped, even if the original request path contains no version. Spring Cloud Gateway matches routes as part of the Spring WebFlux HandlerMapping infrastructure. 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 default implementation of KeyResolver is the PrincipalNameKeyResolver, which retrieves the Principal from the ServerWebExchange and calls Principal.getName(). Then, by default, the gateway metrics filter runs as long as the spring.cloud.gateway.metrics.enabled property is not set to false. reverse proxies. Spring Cloud Gateway includes many built-in route predicate factories. You can also define a rate limiter as a bean that implements the RateLimiter interface. AddResponseHeader is aware of URI variables used to match a path or host. In addition, you can configure this filter once by using spring.cloud.gateway.default-filters and have it applied to all routes. In case of the request being forwarded to fallback, the Spring Cloud CircuitBreaker Gateway filter also provides the Throwable that has caused it. as the separator. The following listing configures a Retry GatewayFilter: A simplified "shortcut" notation can be added with a single status and method. statuses: The HTTP status codes that should be retried, represented by using org.springframework.http.HttpStatus. The resulting response is similar to the following: The response contains the details of all the routes defined in the gateway. The following describes an alternative style gateway. 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. The following example configures an SetResponseHeader GatewayFilter that uses a variable: The SetStatus GatewayFilter factory takes a single parameter, status. AddResponseHeader is aware of URI variables used to match a path or host. 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. method: Method name in the service that handles the request. 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. The parts parameter indicates the number of parts in the path to strip from the request before sending it downstream. You can configure the logging system to have a separate access log file. . This section covers common problems that may arise when you use Spring Cloud Gateway. Code Revisions 1 Stars 14 Forks 3. Once a request has been marked as routed, other routing filters will not route the request again, See the Spring Cloud Project page for details on setting up your build system with the current Spring Cloud Release Train. You can add headers to the downstream response by using the header() methods on ProxyExchange. Well occasionally send you account related emails. 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 appendix provides a list of common Spring Cloud Gateway properties and references to the underlying classes that consume them. This lets you match on anything from the HTTP request, such as headers or parameters. ServerHttpResponse interface. The pattern is an Ant-style pattern with . 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. The The SetRequestHeader GatewayFilter factory takes name and value parameters. The following example configures an after route predicate: This route matches any request made after Jan 20, 2017 17:42 Mountain Time (Denver). .build(); 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. ServerWebExchangeUtils.isAlreadyRouted takes a ServerWebExchange object and checks if it has been routed. 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. pass the authentication token downstream to the services (in this case It uses the Netty HttpClient to make the downstream proxy request. exceptions: A list of thrown exceptions that should be retried. Then, by default, the metrics will be available as long as the property spring.cloud.gateway.metrics.enabled is set to true. httpMethod: The HTTP method used for the request. With MVC, it also supports forwarding to a local handler through the forward() method. - thaneesh shanand Apr 16, 2018 at 1:05 AddRequestParameter is aware of the URI variables used to match a path or host. status codes that if returned will cause the circuit breaker to be tripped. 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. 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 examples show how to set up global pre- and post-filters, respectively: Spring Cloud Gateway provides a utility object called ProxyExchange. The Cookie route predicate factory takes two parameters, the cookie name and a regexp (which is a Java regular expression). The following listing configures a RedirectTo GatewayFilter: This will send a status 302 with a Location:https://acme.org header to perform a redirect. Am I doing it wrong? Since the request can be read only once, we need to cache the request body. It can be used as API gateway in microservice architecture and supports dynamic routing and filtering functions. import static org.springframework.cloud.gateway.support.RouteMetadataUtils.CONNECT_TIMEOUT_ATTR; The maxSize is a DataSize type, so values can be defined as a number followed by an optional DataUnit suffix such as 'KB' or 'MB'. The routine of modifying the response body with Spring Cloud Gateway is the same as the previous request body; Configure routing and filters through code; . By default, the gateway defines a single predicate and filter for routes created with a DiscoveryClient. 4.1. It is the name of the query parameter to be removed. 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. If the input header does not exist, the filter has no impact. If matchTrailingSlash is set to false, then request path /red/1/ will not be matched. Configuring Route Predicate Factories and Gateway Filter Factories, 5.10. 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. Route filters are scoped to a particular route. The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. The following example configures an AddRequestHeadersIfNotPresent GatewayFilter that uses a variable: The AddRequestParameter GatewayFilter Factory takes a name and value parameter. XForwardedRemoteAddressResolver::maxTrustedIndex takes an index that correlates to the number of trusted infrastructure running in front of Spring Cloud Gateway. URI variables may be used in the value and are expanded at runtime. The route configuration allows applying CORS directly to a route as metadata with key cors. AS_IN_REQUEST: The version is stripped only if the original request path contains no version. Service 4.3. This paper will introduce its usage in detail. This predicate matches requests that happen after datetime1 and before datetime2. 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. Zuul profile. It must be a Java System Property, not a Spring Boot property. To write a GatewayFilter, you must implement GatewayFilterFactory as a bean. The algorithm used is the Token Bucket Algorithm. This could be useful for maintenance windows. To enable the Spring Cloud CircuitBreaker filter, you need to place spring-cloud-starter-circuitbreaker-reactor-resilience4j on the classpath. URIs defined in routes without a port get default port values of 80 and 443 for the HTTP and HTTPS URIs, respectively. The Netty routing filter runs if the URL located in the ServerWebExchangeUtils.GATEWAY_REQUEST_URL_ATTR exchange attribute has a http or https scheme. if. If basedOnPreviousValue is true, the backoff is calculated by using prevBackoff * factor. Fork 3. 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). The pile of explanations in front of Xinchen still don . Fully expanded arguments appear more like standard yaml configuration with name/value pairs. Spring Cloud Gateway includes many built-in GatewayFilter Factories. value or the String representation of the HttpStatus enumeration. The Method Route Predicate Factory takes a methods argument which is one or more parameters: the HTTP methods to match. 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 default, when a service instance cannot be found by the, Gateway supports all the LoadBalancer features. URI variables may be used in the value and are expanded at runtime. 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. For more detailed examples of how to use any of the following filters, take a look at the. This is the value of the Location header. regexp, so green and greet would match. The default list of headers that is removed comes from the IETF. You can configure the SetStatus GatewayFilter to return the original HTTP status code from the proxied request in a header in the response. }, 4. Download ZIP. This is the number of tokens taken from the bucket for each request and defaults to 1. Star 14. For each global filter, there is a string representation of the filter object (for example, org.spring[emailprotected]77856cc5) and the corresponding order in the filter chain. 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)'. 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. Server. 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) 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. If Spring Cloud Gateway is, for example only accessible through HAProxy, then a value of 1 should be used.
