/// <summary>
/// Post数据到网站
/// </summary>
/// <param name="posturl">网址</param>
/// <param name="postData">参数</param>
/// <returns></returns>
public string GetPage(string posturl, string postData)
{
Stream outstream = null;
Stream instream = null;
StreamReader sr = null;
HttpWebResponse response = null;
HttpWebRequest request = null;
Encoding encoding = System.Text.Encoding.GetEncoding("UTF-8");
byte[] data = encoding.GetBytes(postData);
// 准备请求...
try
{
// 设置参数
request = WebRequest.Create(posturl) as HttpWebRequest;
CookieContainer cookieContainer = new CookieContainer();
request.CookieContainer = cookieContainer;
request.AllowAutoRedirect = true;
request.Method = "POST";
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = data.Length;
outstream = request.GetRequestStream();
outstream.Write(data, 0, data.Length); ---- body
outstream.Close();
//发送请求并获取相应回应数据
response = request.GetResponse() as HttpWebResponse;
//直到request.GetResponse()程序才开始向目标网页发送Post请求
instream = response.GetResponseStream();
sr = new StreamReader(instream, encoding);
//返回结果网页（html）代码
string content = sr.ReadToEnd();
string err = string.Empty;
return content;
}
catch (Exception ex)
{
string err = ex.Message;
return string.Empty;
}
}
