Question

我一直试图让它工作几个小时而收效甚微。从第一次请求后的源代码我可以看到登录成功，但使用cookie访问其他请求登录信息。

以下是我尝试访问的网站：http://gpro.net/

以下是我正在使用的代码： string formUrl =“http://gpro.net/pl/Login.asp?langCode=pl&Redirect=gpro.asp”; //注意：这是表单POST的URL，而不是表单的URL（您可以在HTML的表单标签的“action”属性中找到它） string formParams =“textLogin = user＆amp; textPassword = pass＆amp; Logon = Login＆amp; LogonFake = Sign + in”;

        string strResponse;
        HttpWebRequest requestLogin = (HttpWebRequest)WebRequest.Create(formUrl);
        requestLogin.Method = "POST";
        requestLogin.CookieContainer = cookieJar;
        requestLogin.ContentType = "application/x-www-form-urlencoded";

        requestLogin.ContentLength = formParams.Length;
        StreamWriter stOut = new StreamWriter(requestLogin.GetRequestStream(), System.Text.Encoding.ASCII);
        stOut.Write(formParams);
        stOut.Close();

        HttpWebResponse responseLogin = (HttpWebResponse)requestLogin.GetResponse();
        StreamReader stIn = new StreamReader(responseLogin.GetResponseStream());
        strResponse = stIn.ReadToEnd();
        stIn.Close();
        sb.Append(strResponse);
        sb.AppendLine();
        sb.AppendLine();
        sb.AppendLine();
        //Add cookies to CookieJar (Cookie Container)
        foreach (Cookie cookie in responseLogin.Cookies)
        {
            cookieJar.Add(new Cookie(cookie.Name.Trim(), cookie.Value.Trim(), cookie.Path, cookie.Domain));
            sb.AppendLine(cookie.Name.ToString() + Environment.NewLine + cookie.Value.ToString() + Environment.NewLine + cookie.Path.ToString() + Environment.NewLine + cookie.Domain.ToString());
        }

        //Grab the cookie we just got back for this specifc page

        string cookies = cookieJar.GetCookieHeader(requestLogin.RequestUri);


        //put it back in the cookie container for the whole server

        cookieJar.SetCookies(new Uri("http://www.gpro.net/"), cookies);

        string testResults = string.Empty;
        HttpWebRequest runTest = (HttpWebRequest)WebRequest.Create("http://www.gpro.net/pl/RaceAnalysis.asp");
        runTest.Referer = "http://gpro.net/pl/gpro.asp";
        runTest.CookieContainer = cookieJar;
        //runTest.Method = "POST";
        //runTest.ContentType = "application/x-www-form-urlencoded";
        //StreamWriter stOut2 = new StreamWriter(runTest.GetRequestStream(), System.Text.Encoding.ASCII);
        //stOut2.Write(formParams);
        //stOut2.Close();
        StreamReader stIn2 = new StreamReader(runTest.GetResponse().GetResponseStream());
        testResults = stIn2.ReadToEnd();
        stIn2.Close();
        sb.Append(testResults);
        e.Result = sb.ToString();

我发现上面的代码有什么问题，并且堆栈溢出中发布的每个类似的代码（我已经尝试了所有标记为工作）。当我使用浏览器重定向进行日志记录工作正常时，但使用上述方法我的请求被重定向到相同的地址，但没有www前缀。这产生了两个不同的cookie集合。我从解决登录问题的每个请求中删除了www前缀。
