使用 Cookie 的 C# WebRequest

Question

我有一个我一直在开发的 winforms 应用程序，它对消费者帐户运行多个测试。测试需要一次性登录才能执行。

string paramaters = "authmethod=on&chkRememberMe=on&login-form-type=pwd&password=" + pw.Text + "&userid=" + uid.Text + "&username=" + uid.Text;
        string strResponse;
        HttpWebRequest requestLogin = (HttpWebRequest)WebRequest.Create("https://www.url.com/login.form");
        requestLogin.Method = "POST";
        requestLogin.CookieContainer = cookieJar;
        requestLogin.ContentType = "application/x-www-form-urlencoded";

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

        StreamReader stIn = new StreamReader(requestLogin.GetResponse().GetResponseStream());
        strResponse = stIn.ReadToEnd();
        stIn.Close();

此脚本适用于登录，问题是当我需要实际运行测试时，我需要将所有结果返回到一个字符串中(HTML 结果)。

private string runTestRequest(Uri url, string parameters)
    {
        string testResults = string.Empty;
        HttpWebRequest runTest = (HttpWebRequest)WebRequest.Create(url);
        runTest.CookieContainer = cookieJar;
        runTest.Method = "POST";
        runTest.ContentType = "application/x-www-form-urlencoded";
        StreamWriter stOut = new StreamWriter(runTest.GetRequestStream(), System.Text.Encoding.ASCII);
        stOut.Write(parameters);
        stOut.Close();
        StreamReader stIn = new StreamReader(runTest.GetResponse().GetResponseStream());
        testResults = stIn.ReadToEnd();
        stIn.Close();
        return testResults;
    }

但是它会尝试登录。我如何将之前登录请求中的 Cookie 与此以及许多其他 Web 请求一起使用？

感谢您的帮助。

编辑:

我将它添加到我的代码中，但它应该做与 BrokenGlass 所说的相同的事情，只是有点不同但仍然不起作用。

foreach (Cookie cookie in responseLogin.Cookies)
        {
            cookieJar.Add(new Cookie(cookie.Name.Trim(), cookie.Value.Trim(), cookie.Path, cookie.Domain));
            richTextBox2.Text += cookie.Name.ToString() + Environment.NewLine + cookie.Value.ToString() + Environment.NewLine + cookie.Path.ToString() + Environment.NewLine + cookie.Domain.ToString();
        }

这样的事情应该可行，我正在使用类似的代码来保存登录 cookie:

HttpWebRequest runTest;
//...do login request
//get cookies from response

CookieContainer myContainer = new CookieContainer();
for (int i = 0; i < Response.Cookies.Count; i++)
{
   HttpCookie http_cookie = Request.Cookies[i];
   Cookie cookie = new Cookie(http_cookie.Name, http_cookie.Value, http_cookie.Path);
   myContainer.Add(new Uri(Request.Url.ToString()), cookie);
}

//later:
HttpWebRequest request = (HttpWebRequest)WebRequest.Create("http://www.url.com/foobar");
request.CookieContainer = myContainer;
