C#模拟登录Facebook实现发送消息、评论帖子

原作者: [db:作者] 来自: [db:来源] 收藏 邀请

由于目前电脑网页版FB实现模拟登录比较困难,本次选择了FB的手机版页面进行登录

MVC:

     private static string UserName = "用户名";
        private static string PassWord = "密码";

        public ActionResult Index()
        {
            return View();
        }

        public CookieContainer Login()
        {
            CookieContainer cookie = new CookieContainer();
            HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("https://m.facebook.com");
            //WebProxy Proxy = new WebProxy("127.0.0.1", 1080);
            //request.Proxy = Proxy;
            request.Method = "GET";
            request.CookieContainer = cookie;
            request.ContentType = "application/x-www-form-urlencoded";
            request.UserAgent = "Mozilla/5.0 (Windows NT 10.0; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.102 Safari/537.36";
            request.Accept = "*/*";
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            Stream ResponseStream = response.GetResponseStream();
            StreamReader sr = new StreamReader(ResponseStream, Encoding.UTF8);
            string html = sr.ReadToEnd();
            sr.Close();
            ResponseStream.Close();

            string li = Regex.Match(html, @"<input type=""hidden"" name=""li"" value=""(.*?)"" />").Groups[1].Value;
            string lsd = Regex.Match(html, @"<input type=""hidden"" name=""lsd"" value=""(.*?)"" autocomplete=""off"" />").Groups[1].Value;
            string m_ts = Regex.Match(html, @"<input type=""hidden"" name=""m_ts"" value=""(.*?)"" />").Groups[1].Value;
            string PostStr = "lsd=" + lsd + "&charset_test=%E2%82%AC%2C%C2%B4%2C%E2%82%AC%2C%C2%B4%2C%E6%B0%B4%2C%D0%94%2C%D0%84&version=1&ajax=0&width=0&pxr=0&gps=0&dimensions=0&m_ts=" + m_ts + "&li=" + li + "&email=" + UserName + "&pass=" + PassWord + "&login=%E7%99%BB%E5%BD%95";

            return Post(PostStr, cookie);
        }

        public CookieContainer Post(string PostStr, CookieContainer cookie)
        {
            byte[] PostData = Encoding.UTF8.GetBytes(PostStr);
            HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create("https://m.facebook.com/login.php?refsrc=https://m.facebook.com/&lwv=100&refid=8");
            //WebProxy Proxy = new WebProxy("127.0.0.1", 1080);
            //request.Proxy = Proxy;

            request.KeepAlive = true;
            request.ContentLength = PostData.Length;
            Stream RequestStream = request.GetRequestStream();
            RequestStream.Write(PostData, 0, PostData.Length);
            RequestStream.Close();
