通过code，有重定向下载文件？ [英] Download file through code that has a redirect?

问题描述

我在数据库中有一些网址。这个问题是存在的URL是重定向到我想要的网址。

I have some urls in the database. The problem is there urls are urls that redirect to what I want.

我有这样的事情

http://www.mytestsite.com/test/test/?myphoto=真正的

现在，如果我去这个网站它会做一个重定向到的照片，以便该URL将最终被

now if I go to this site it would do a redirect to the photo so the url would end up being

http://www.mytestsite.com/test/myphoto.jpg

是否有可能以某种方式刮（下载）到C＃，然后把它重定向，并得到真正的URL，这样我可以下载图片？

Is it possible to somehow scrape(download) through C# and then have it redirect and get the real url so I can download the image?

推荐答案

我觉得你是在<一个href="http://msdn.microsoft.com/en-us/library/system.net.httpwebrequest.allowautoredirect.aspx">HttpWebRequest.AllowAutoRedirect属性。该属性获取或设置一个值，该值指示请求是否应跟随重定向响应。

I think you are after the HttpWebRequest.AllowAutoRedirect Property. The property gets or sets a value that indicates whether the request should follow redirection responses.

示例从MSDN采取

HttpWebRequest myHttpWebRequest=(HttpWebRequest)WebRequest.Create("http://www.contoso.com");    
myHttpWebRequest.MaximumAutomaticRedirections=1;
myHttpWebRequest.AllowAutoRedirect=true;
HttpWebResponse myHttpWebResponse=(HttpWebResponse)myHttpWebRequest.GetResponse();
