C＃WebRequest登錄會話

Question

好吧，我昨天嘗試過問這個問題，但是我不確定是否提供了足夠的信息，我得到了答案，但是它對我沒有用。 基本上，我正在做的是用戶打開此Windows Forms應用程序並登錄。然后，他們在文本框中輸入一些文本，然后單擊“運行”。 此時，運行功能正在向需要登錄的服務器發出Web請求（登錄是他們打開程序后最初完成的登錄。出於某種原因，即使執行第二個請求，它仍看不到用戶已登錄我也不確定我在做什么錯，但是我會發布我的代碼，以便您進一步為我提供幫助。

這是用戶進入應用程序時用於登錄的功能。

private void button1_Click(object sender, EventArgs e)
{
    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();

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

    //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));
        richTextBox2.Text += cookie.Name.ToString() + Environment.NewLine + cookie.Value.ToString() + Environment.NewLine + cookie.Path.ToString() + Environment.NewLine + cookie.Domain.ToString();
    }

    if (strResponse.Contains("Log On Successful") || strResponse.Contains("already has a webseal session"))
    {
        foreach (Control cont in this.Controls)
        {
            cont.Visible = true;
        }
        loginPanel.SendToBack();
        loginPanel.Visible = false;
    }
    else
    {
        MessageBox.Show("Login failed.");
    }
}

這是用戶單擊“運行”按鈕以在消費者帳戶上啟動測試時運行的功能。

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;
}

當然這是我的cookie容器對象

public CookieContainer cookieJar = new CookieContainer();

PS：Web請求的域不同。 首先是abc.com，第二是123.com唯一的問題是，第一個域（即登錄名）是內部Web應用程序（如123.com）的全局登錄名，因此我將如何使用第一個域中的登錄會話第二個域？

能否請您幫助我弄清楚我在做什么錯。

string url = "http://www.ABC/MemberShip/Login.aspx";// HttpContext.Current.Request.Url.AbsoluteUri.ToString().Replace("AutoLogin", "Login");
CookieContainer myCookieContainer = new CookieContainer();
HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
request.CookieContainer = myCookieContainer;
request.Method = "GET";
request.KeepAlive = false;

HttpWebResponse response = request.GetResponse() as HttpWebResponse;

System.IO.Stream responseStream = response.GetResponseStream();
System.IO.StreamReader reader = new System.IO.StreamReader(responseStream, Encoding.UTF8);
string srcString = reader.ReadToEnd();

// get the page ViewState                
string viewStateFlag = "id=\"__VIEWSTATE\" value=\"";
int i = srcString.IndexOf(viewStateFlag) + viewStateFlag.Length;
int j = srcString.IndexOf("\"", i);
string viewState = srcString.Substring(i, j - i);

// get page EventValidation                
string eventValidationFlag = "id=\"__EVENTVALIDATION\" value=\"";
i = srcString.IndexOf(eventValidationFlag) + eventValidationFlag.Length;
j = srcString.IndexOf("\"", i);
string eventValidation = srcString.Substring(i, j - i);

string submitButton = "LoginButton";

// UserName and Password
string userName = "userid";
string password = "password";
// Convert the text into the url encoding string
viewState = System.Web.HttpUtility.UrlEncode(viewState);
eventValidation = System.Web.HttpUtility.UrlEncode(eventValidation);
submitButton = System.Web.HttpUtility.UrlEncode(submitButton);

// Concat the string data which will be submit
string formatString =
         "txtUserName={0}&txtPassword={1}&btnSignIn={2}&__VIEWSTATE={3}&__EVENTVALIDATION={4}";
string postString =
         string.Format(formatString, userName, password, submitButton, viewState, eventValidation);

// Convert the submit string data into the byte array
byte[] postData = Encoding.ASCII.GetBytes(postString);

// Set the request parameters
request = WebRequest.Create(url) as HttpWebRequest;
request.Method = "POST";
request.Referer = url;
request.KeepAlive = false;
request.UserAgent = "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1; WOW64; Trident/4.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; Media Center PC 6.0; InfoPath.2; CIBA)";
request.ContentType = "application/x-www-form-urlencoded";
request.CookieContainer = myCookieContainer;
System.Net.Cookie ck = new System.Net.Cookie("TestCookie1", "Value of test cookie");
ck.Domain = request.RequestUri.Host;
request.CookieContainer.Add(ck);
request.CookieContainer.Add(response.Cookies);

request.ContentLength = postData.Length;

// Submit the request data
System.IO.Stream outputStream = request.GetRequestStream();
request.AllowAutoRedirect = true;
outputStream.Write(postData, 0, postData.Length);
outputStream.Close();


// Get the return data
response = request.GetResponse() as HttpWebResponse;
responseStream = response.GetResponseStream();
reader = new System.IO.StreamReader(responseStream, Encoding.UTF8);
srcString = reader.ReadToEnd();
Response.Write(srcString);
Response.End();

我發現發生了什么事，它正在使用與登錄名相同的第二個域（123.com）重定向到一個子域。 顯然，他們擁有在多個域上構建的全局登錄系統來傳遞cookie。 上面的代碼確實可以工作，我現在也可以正常工作。 謝謝！！
