我一直试图让它工作几个小时,但收效甚微。从第一次请求后的源代码中,我可以看到登录成功,但使用 cookie 访问其他人不断询问登录信息。

这是我要访问的网站:http: //gpro.net/

这是我正在使用的代码: string formUrl = "http://gpro.net/pl/Login.asp?langCode=pl&Redirect=gpro.asp"; // 注意:这是表单发布到的 URL,而不是表单的 URL(您可以在 HTML 表单标签字符串的“action”属性中找到它 formParams = "textLogin=user&textPassword=pass&Logon=Login&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();

我发现上面的代码和堆栈溢出中发布的每个类似代码有什么问题(我已经尝试过所有标记为工作)。当我使用浏览器重定向登录时工作正常,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。这导致了两个不同的 cookie 集合。我从解决登录问题的每个请求中删除了 www 前缀。
