一个网站的入口是A.com/test.aspx?sn=xxxxxx 跳转到B.com/ts.aspx .请问怎么通过程序获取到跳转后的地址呢

[guohouchang]

  HttpWebRequest req = (HttpWebRequest)WebRequest.Create(sRequestUrl);
                req.Method = "HEAD"; req.AllowAutoRedirect = false;
          
                HttpWebResponse myResp = (HttpWebResponse)req.GetResponse();
                if (myResp.StatusCode == HttpStatusCode.Redirect)
                { string ts = myResp.GetResponseHeader("Location"); }

这样还是不行, 我想取到 B.com/ts.aspx 的结果

[娃都会打酱油了]

string url = @"http://localhost:2426/WebForm1.aspx";
HttpWebRequest req = (HttpWebRequest)WebRequest.Create(url);
var response = (HttpWebResponse)req.GetResponse();
Console.WriteLine(response.StatusCode);
Console.WriteLine(response.ResponseUri);//输出http://www.baidu.com/

做的demo跳转的百度首页，貌似没取到302那个页面

这个连接跳转之后是微信公众号文章的详情地址.而这样取到的还是搜狗的地址

[娃都会打酱油了]

你这个地址在浏览器打开提示已经过期，重新加载就到首页了

[by_封爱]

获取不了吧. 因为跳转的方式有很多 假如你在a.com.text.aspx写js跳转或者服务器跳转 对用户来说 都是跳转. 但是你不管如何请求 可能返回字符串 也可能是别的东西,..

[guohouchang]

其实我就是想通过搜狗采集微信文章的内容

哈哈同样寻求方法啊,,,,

[crystal_lz]

把 httpwebrequest 的 autoredirect 设置成false 就可以了 他就不会自动跳转了 然后 你自己去处理 或者 从 httpwebresponse 上面去最终的连接也行
