ForwardedHeaderTransformer (Spring Framework 5.2.12.RELEASE API)

java.lang.Object
- org.springframework.web.server.adapter.ForwardedHeaderTransformer

所有已实现的接口:
Function<ServerHttpRequest,ServerHttpRequest>
直接已知子类:
ForwardedHeaderFilter
```
public class ForwardedHeaderTransformer
extends Object
implements Function<ServerHttpRequest,ServerHttpRequest>
```
Extract values from "Forwarded" and "X-Forwarded-*" headers to override the request URI (i.e. HttpRequest.getURI()) so it reflects the client-originated protocol and address.
Alternatively if removeOnly is set to "true", then "Forwarded" and "X-Forwarded-*" headers are only removed, and not used.
An instance of this class is typically declared as a bean with the name "forwardedHeaderTransformer" and detected by WebHttpHandlerBuilder.applicationContext(ApplicationContext), or it can also be registered directly via WebHttpHandlerBuilder.forwardedHeaderTransformer(ForwardedHeaderTransformer).
