截断查询字符串和放大器;返回清洁网址C＃ASP.net [英] Truncating Query String & Returning Clean URL C# ASP.net

问题描述

我想借原始URL，截断查询字符串参数，并返回URL的清理版本。我想它在整个应用程序出现，因此，通过执行在Global.asax将是理想的。另外，我觉得301重定向将是顺序。

I would like to take the original URL, truncate the query string parameters, and return a cleaned up version of the URL. I would like it to occur across the whole application, so performing through the global.asax would be ideal. Also, I think a 301 redirect would be in order as well.

即

在：www.website.com/default.aspx?utm_source=twitter&utm_medium=social-media

in: www.website.com/default.aspx?utm_source=twitter&utm_medium=social-media

出：www.website.com/default.aspx

out: www.website.com/default.aspx

什么是实现这一目标的最佳途径？

What would be the best way to achieve this?

推荐答案

的System.Uri这里是你的朋友。这上面有很多有用的实用程序，但是你想要的是GetLeftPart：

System.Uri is your friend here. This has many helpful utilities on it, but the one you want is GetLeftPart:

 string url = "http://www.website.com/default.aspx?utm_source=twitter&utm_medium=social-media";
 Uri uri = new Uri(url);
 Console.WriteLine(uri.GetLeftPart(UriPartial.Path));

这给出了输出： http://www.website.com/default.aspx

[Uri类确实需要的协议，HTTP：//，被指定]

[The Uri class does require the protocol, http://, to be specified]

GetLeftPart basicallys说：得到URI的最多的我指定的部分的左部。这可能是方案（只是http：//位），管理委员会（www.website.com部分），路径（/default.aspx）或查询（查询字符串）

GetLeftPart basicallys says "get the left part of the uri up to the part I specify". This can be Scheme (just the http:// bit), Authority (the www.website.com part), Path (the /default.aspx) or Query (the querystring).

假设你是一个aspx页面上，你可以再使用的Response.Redirect（NEWURL）重定向来电。

Assuming you are on an aspx web page, you can then use Response.Redirect(newUrl) to redirect the caller.
