I'm scraping a site with HttpWebRequest, but the site is returning an error. The page works fine when I hit it from my browser. I'd like to compare them to see what may be causing the error. I know how to intercept the request from my browser to inspect the headers, but how do I view the data sent by HttpWebRequest?

推荐答案

为了比较您在代码中所做的工作以及浏览器的工作，我确定可以使用HTTP调试工具，例如

In order to compare what you do in code, and what the browser does, I am sure a HTTP debugging tool such as Fiddler, would be the easiest solution.

提琴手充当客户端和服务器之间的代理，并显示通过HTTP协议发送的所有信息.

Fiddler acts as a proxy between client and server, and displays all information sent over the HTTP protocol.

可能需要将.NET应用程序配置为使用Fiddler提供的代理.此博客文章提供了有关该主题的详细信息.

It is possible that you will need to configure your .NET app to use the proxy that Fiddler provides. This blog post provides details on the subject.
