用代码向网站提交数据

用代码向网站提交数据

左直拳

可以用代码模拟浏览器向网站提交数据：

string sUrl = "http://。。。。";//目标网址

Uri target = new Uri(sUrl);

HttpWebRequest req = (HttpWebRequest)WebRequest.Create(target);

req.ReadWriteTimeout = 10000;

req.Timeout = 10000;

req.MaximumAutomaticRedirections = 5;

req.MaximumResponseHeadersLength = 5;

req.AllowAutoRedirect = true;

//装扮成一个浏览器，欺骗那个网址

req.UserAgent = "Mozilla/6.0 (compatible; MSIE 6.0; Windows NT 5.1)";

req.Method = "POST";

req.ContentType = "application/x-www-form-urlencoded";

string postData = "voteid=15196&markinfo=0&checktype=2&op=69884";//传递的数据

byte[] arPostData = Encoding.UTF8.GetBytes(postData);

req.ContentLength = arPostData.Length;

Stream newStream = req.GetRequestStream();

newStream.Write(arPostData, 0, arPostData.Length);

newStream.Close();

如果目标网址需要输入验证码，则死翘翘。
