推荐答案

创建HttpRequest对象时，有一个属性允许您提供凭据。如果您尝试下载的资源需要身份验证，则应使用用户名和密码创建 NetworkCredential 的实例。



这样的事情：

When you create an HttpRequest object, there is a property to allow you to supply credentials. You should create an instance of NetworkCredential with the username and password if the resource you are trying to download requires authentication.

Something like this:

HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("http://some.web.site/some.resource.ext");
NetworkCredential nc = new NetworkCredential("user", "password");
request.Credentials = nc;

private void AutoLogin()
        {
            string appURL = "http://zl.qq.com/server/webLogin.shtml";
            //string strPostData = String.Format("userName={0}&password={1}",
            //"71444468", "0113,,@tom..com");
            NetworkCredential nc = new NetworkCredential("user", "password");

            // Setup the http request.      
            HttpWebRequest wrWebRequest = WebRequest.Create(appURL) as
            HttpWebRequest;
            wrWebRequest.Method = "post";
            //wrWebRequest.ContentLength = strPostData.Length;
            //wrWebRequest.ContentType = "application/x-www-form-urlencoded";
            wrWebRequest.Credentials = nc;

            CookieContainer cookieContainer = new CookieContainer();
            wrWebRequest.CookieContainer = cookieContainer;

            // Post to the login form.      
            StreamWriter swRequestWriter = new StreamWriter(wrWebRequest.GetRequestStream());
            swRequestWriter.Write(nc);
            swRequestWriter.Close();
            // Get the response.      
            HttpWebResponse hwrWebResponse = (HttpWebResponse)wrWebRequest.GetResponse();
            // Read the response      
            StreamReader srResponseReader = new
            StreamReader(hwrWebResponse.GetResponseStream());
            string strResponseData = srResponseReader.ReadToEnd();
            srResponseReader.Close();

            
            //Response.Write(strResponseData);
            //return cookieContainer;
        }
