Package com.networknt.handler

Class RequestInterceptorInjectionHandler

java.lang.Object

com.networknt.handler.RequestInterceptorInjectionHandler

All Implemented Interfaces:

LightHttpHandler, MiddlewareHandler, io.undertow.server.HttpHandler

public class RequestInterceptorInjectionHandler
extends Object
implements MiddlewareHandler

This is the middleware used in the request/response chain to inject the implementations of RequestInterceptorHandler interface to modify the request metadata and body. You can have multiple interceptors per application; however, we do provide a generic implementation in request-transform module to transform the request based on the rule engine rules.
