RequestDispatcher是否会转发原始请求的HTTP方法? [英] Does a RequestDispatcher forward maintain the original request's HTTP method?

问题描述

我想使用RequestDispatcher拦截请求，然后将请求转发到另一个servlet-像这样:

I want to intercept a request using the RequestDispatcher, and then I want to forward the request along to another servlet -- something like this:

RequestDispatcher dispatcher = request.getRequestDispatcher("/servlet/some.ThirdPartyServlet" + "?" + "param_name=" + "somevalue");
dispatcher.forward(request, response);

如果传入的请求是POST，请求分派器将采用我的新参数，并将其包含在消息正文中，还是现在转发成为GET?

If the incoming request were a POST, will the request dispatcher take my new parameters, and include them in the message body, or does this forward now become a GET?

推荐答案

它保留原始请求，而不更改它.

It retains the original request, without changing it.

因此，如果它是POST，它将保留为POST.

So, it will remain POST if it was POST.
