Question

好吧我昨天试过问这个问题，但我不确定我是否提供了足够的信息，我得到了答案，但它对我没用。基本上我正在做的是用户打开这个窗体表单应用程序并登录。之后，他们将一些文本输入文本框并单击运行。此时，运行功能正在向需要登录的服务器（最初在打开程序后完成的登录）进行webrequest。由于某种原因，在执行第二个请求时仍然没有看到用户登录，即使饼干也被添加到一个cookie容器中。我不确定我做错了什么，但我会发布我的代码，以便你可以进一步帮助我。

这是用户进入应用程序时为登录执行的功能。

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.");
    }
}

这是当用户点击“运行”按钮启动消费者帐户测试时运行的功能。

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;
}

当然这是我的cookie容器对象

public CookieContainer cookieJar = new CookieContainer();

P.S。：网络请求的域名是不同的。首先是abc.com第二个是123.com唯一的问题是第一个域（即登录）是123.com等内部Web应用程序的全局登录，那么我将如何使用来自第一个域的登录会话第二个域？

请帮助我帮助我弄清楚我做错了什么。

Answer 1

我发现发生的事情是它正在重新定位到与第二个（123.com）相同的域上的子域以使用登录。显然他们有这个基于多个域的全局登录系统来传递cookie。上面的代码可以工作，我现在可以使用它。谢谢！

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();
