Class HiddenHttpMethodFilter
java.lang.Object
org.springframework.web.filter.reactive.HiddenHttpMethodFilter
- All Implemented Interfaces:
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.
