C#自动登录Sina

 

public static CookieContainer Get_SinaLogin()
        {
            CookieContainer cc = new CookieContainer();
            string FormURL = "http://my.blog.sina.com.cn/login.php?index=index&type=new";                //处理表单的绝对URL地址
            string FormData = "loginname=yourname&passwd=yourpassword";    //表单需要提交的参数，注意改为你已注册的信息。

            Encoding encoding = Encoding.UTF8;                        
            byte[] data = encoding.GetBytes(FormData);         

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(FormURL);
            request.Method = "POST";    //数据提交方式
            request.ContentType = "application/x-www-form-urlencoded";
            request.ContentLength = data.Length;
            request.UserAgent = "Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.1; SV1; .NET CLR 1.1.4322)";
            //模拟一个UserAgent
            Stream newStream = request.GetRequestStream();
            newStream.Write(data, 0, data.Length);

            newStream.Close();

            request.CookieContainer = cc;

            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            cc.Add(response.Cookies);
            Stream stream = response.GetResponseStream();
            string WebContent = new StreamReader(stream, System.Text.Encoding.UTF8).ReadToEnd();
            return cc;
        }

 

 

在需要登录的按钮事件里
private void button1_Click(object sender, EventArgs e)
        {
            //调用以上的方法来获取需要登录才能查看的内容。    
            CookieContainer cc = new CookieContainer();
            cc = GetHtml.Get_SinaLogin();        //获取登录Cookies

            string PhotoClassURL ="http://control.blog.sina.com.cn/admin/article/article_add.php";
            HttpWebRequest Myrequest = (HttpWebRequest)WebRequest.Create(PhotoClassURL);
            Myrequest.CookieContainer = cc;
            HttpWebResponse Myresponse = (HttpWebResponse)Myrequest.GetResponse();
            cc.Add(Myresponse.Cookies);
            Stream Mystream = Myresponse.GetResponseStream();
            string sHtml = new StreamReader(Mystream, System.Text.Encoding.UTF8).ReadToEnd();
            //sHtml即为你登录之后看到的内容.
            MessageBox.Show(sHtml);
        }
