我如何拦截出站和入肥皂从C＃客户端Web代理消息 [英] How Do I Intercept Outbound and Inbound Soap Messages from C# Client Side Web Proxy

问题描述

我写的UI来测试ASMX Web服务。服务器和客户端.NET。客户端代理一直使用Wsdl.exe用生成的。

I'm writing UI to test an asmx web service. Server and client are .NET. Client proxy has been generated using wsdl.exe.

我想拦截并存储传出和传入的 SOAP的字符串表示形式生成的讯息调用Web代理方法的结果，因此我可以添加一个功能，它会显示该消息只是发送/接收的用户界面。

I would like to intercept and store a string representation of outgoing and incoming SOAP messages generated as a result of calling methods on the web proxy, so I can add a feature to the UI which will show the message just sent/received.

我依稀记得有两个在哪里可以可以添加代码的扩展点对来intecept的消息，但我不记得这是怎么做的。我认为例子我在参与压缩客户端上的消息，并在服务器上反向的某些部分，即使在我的情况，我想存储而不是改变邮件的头脑。

I dimly recall there are two pairs of extension points where code can can be added to intecept the message but I cannot remember how this was done. I think the examples I have in mind involved compressing some part of the message on the client and the reverse on the server, even though in my scenario, I want to store rather than alter the message.

任何提示和帮助感激地接受。

Any hints and help gratefully received.

（我已经部分地实现了一个的SoapExtension，我不明白ChainStream方法是如何工作的，我也不太清楚如何通知SOAP消息已经被困（因为我在实例化SOAP扩展的控制又不是）的监听器。

(I've partially implemented a SoapExtension. I don't understand how the ChainStream method works, and I'm not sure how to notify a listener that a soap message has been trapped (since I'm not in control of instantiating the soap extension).'

推荐答案

您是在正确的轨道上的SoapExtension。你看到的文档和示例在这里？的 http://msdn.microsoft.com/en-us/library/system.web.services.protocols.soapextension.aspx

You're on the right track with SoapExtension. Did you see the documentation and example here? http://msdn.microsoft.com/en-us/library/system.web.services.protocols.soapextension.aspx

与ChainStream的想法是你获得通过，该请求将被写入到网络流，你必须返回一个不同的数据流的选项。所以，如果你要保存的请求的副本，返回一个MemoryStream，这对Web服务客户端将写请求进去，然后在ProcessMessage的调用可以将数据复制出来的那里，它传递给你的用户界面。

The idea with ChainStream is you get passed the network stream that the request would be written to, and you have the option of returning a different stream. So if you want to save a copy of the request, return a MemoryStream, which the web services client will write the request into, and then in the ProcessMessage call you can copy the data out of there and pass it to your UI.
