中继在asp.net请求（转发请求） [英] Relaying a request in asp.net (Forwarding a request)

问题描述

我有两个不同的Web应用程序之间进行通信的Web应用程序（一个接收器和一个发送器，发送器与我的应用程序进行通信，而我的应用程序与两个通信）。

I have a web application that communicates between two different web applications (one receiver and one sender, the sender communicates with my application, and my application communicates with both).

一个经常的情况是，发送方发送一个HTTPRequest，我的应用程序，我接受它在一个HttpHandler。这反过来将HttpContext的一些businesslogic做一些水管。

A regular scenario is that the sender sends a HttpRequest to my application, and I receive it in an HttpHandler. This in turn sends the HttpContext to some businesslogic to do some plumbing.

我的商业课程完成存储数据之后（一些日志记录等），我想传达了同样的要求与所有的标头，形成到接收器的应用数据等。这必须从类中发送，而不是HttpHandler的

After my business classes are finished storing data (some logging etc), I want to relay the same request with all the headers, form data etc to the receiver application. This must be sent from the class, and not the HttpHandler.

真正的问题是 - 我怎么可以把一个HttpContext对象，并转发/只继电器完全相同的请求修改从 http://myserver.com/ URL来 HTTP：// receiver.com 。

The question is really - how can I take a HttpContext object, and forward/relay the exact same request only modifying the URL from http://myserver.com/ to http://receiver.com.

在任何最好的代码示例C＃将是伟大的！

Any code examples in preferable c# would be great!

推荐答案

其实，像这样行之有效

HttpRequest original = context.Request;
HttpWebRequest newRequest = (HttpWebRequest)WebRequest.Create(newUrl);

newRequest .ContentType = original.ContentType;
newRequest .Method = original.HttpMethod;
newRequest .UserAgent = original.UserAgent;

byte[] originalStream = ReadToByteArray(original.InputStream, 1024);

Stream reqStream = newRequest .GetRequestStream();
reqStream.Write(originalStream, 0, originalStream.Length);
reqStream.Close();


newRequest .GetResponse();

编辑：ReadToByteArray方法只是使从流

edit: ReadToByteArray method just makes a byte array from the stream
