HiddenHttpMethodFilter (Spring Framework 5.2.12.RELEASE API)

java.lang.Object
- org.springframework.web.filter.reactive.HiddenHttpMethodFilter

所有已实现的接口:
WebFilter
```
public class HiddenHttpMethodFilter
extends Object
implements WebFilter
```
Reactive WebFilter that converts posted method parameters into HTTP methods, retrievable via HttpRequest.getMethod(). Since browsers currently only support GET and POST, a common technique is to use a normal POST with an additional hidden form field (_method) to pass the "real" HTTP method along. This filter reads that parameter and changes the HttpRequest.getMethod() return value using ServerWebExchange.mutate().
The name of the request parameter defaults to _method, but can be adapted via the methodParamName property.
