POST（登录）后获取请求

Question

我有一个网站，我每天都会查看我的产品列表。我想为它做一个桌面程序。

我需要先登录该网站，然后才能访问网站。com/v1/ProductList 这是一个 xml 文档。我已成功使用此代码登录：

            CookieCollection cookies = new CookieCollection();
        HttpWebRequest request = (HttpWebRequest)WebRequest.Create(FirstURL);
        request.CookieContainer = new CookieContainer();
        request.CookieContainer.Add(cookies);
        //Get the response from the server and save the cookies from the first request..
        HttpWebResponse response = (HttpWebResponse)request.GetResponse();
        cookies = response.Cookies;
        string postData = "Username=x&Password=x&List=1&Submit=Submit";
        HttpWebRequest getRequest = (HttpWebRequest)WebRequest.Create(getUrl);
        getRequest.CookieContainer = new CookieContainer();
        getRequest.CookieContainer.Add(cookies); //recover cookies First request
        getRequest.Method = WebRequestMethods.Http.Post;
        getRequest.UserAgent = "Mozilla/5.0 (Windows NT 6.1) AppleWebKit/535.2 (KHTML, like Gecko) Chrome/15.0.874.121 Safari/535.2";
        getRequest.AllowWriteStreamBuffering = true;
        getRequest.ProtocolVersion = HttpVersion.Version11;
        getRequest.AllowAutoRedirect = true;
        getRequest.ContentType = "application/x-www-form-urlencoded";

        byte[] byteArray = Encoding.ASCII.GetBytes(postData);
        getRequest.ContentLength = byteArray.Length;
        Stream newStream = getRequest.GetRequestStream(); //open connection
        newStream.Write(byteArray, 0, byteArray.Length); // Send the data.
        newStream.Close();

        HttpWebResponse getResponse = (HttpWebResponse)getRequest.GetResponse();
        using (StreamReader sr = new StreamReader(getResponse.GetResponseStream()))
        {
            string sourceCode = sr.ReadToEnd();
        }

至此我登录成功了。但是在此之后，如果我为我的列表（站点。com/v1/ProductList）创建一个新的获取请求并获取请求，它会将我重定向到登录页面。

编辑：我刚刚意识到我登录后无法获得任何 cookie。它说“'enumeration yielded no results'”。

我现在不知道如何解决它。

谢谢

更改此行：

getRequest.AllowAutoRedirect = true;

对此：

getRequest.AllowAutoRedirect = false;

确保您确实将其设置为 false 而不要只是删除该行，因为默认情况下，它会设置为 true.
