復制代碼 代碼如下:

private string GetHTMLTCP(string URL)
{
string strHTML = "";//用來保存獲得的HTML代碼
TcpClient clientSocket = new TcpClient();
Uri URI = new Uri(URL);
clientSocket.Connect(URI.Host, URI.Port);
StringBuilder RequestHeaders = new StringBuilder();//用來保存HTML協議頭部信息
RequestHeaders.AppendFormat("{0} {1} HTTP/1.1/r/n", "GET", URI.PathAndQuery);
RequestHeaders.AppendFormat("Connection:close/r/n");
RequestHeaders.AppendFormat("Host:{0}/r/n", URI.Host);
RequestHeaders.AppendFormat("Accept:*/*/r/n");
RequestHeaders.AppendFormat("Accept-Language:zh-cn/r/n");
RequestHeaders.AppendFormat("User-Agent:Mozilla/4.0 (compatible; MSIE 6.0; Windows NT 5.2; SV1; .NET CLR 1.1.4322; .NET CLR 2.0.50727)/r/n/r/n");
Encoding encoding = Encoding.Default;
byte[] request = encoding.GetBytes(RequestHeaders.ToString());
clientSocket.Client.Send(request);
//獲取要保存的網絡流
Stream readStream = clientSocket.GetStream();
StreamReader sr = new StreamReader(readStream, Encoding.Default);
strHTML = sr.ReadToEnd();
readStream.Close();
clientSocket.Close();
return strHTML;
}

復制代碼 代碼如下:

///
/// 獲取html源碼
///
///
///
///
static string GetHTML(string url, string param)
{
try
{
Uri uri = new Uri(url);
HttpWebRequest myReq = (HttpWebRequest)WebRequest.Create(uri);
myReq.Headers.Add("Accept-Encoding", "gzip,deflate");//sdch
byte[] byData = Encoding.Default.GetBytes(param);
myReq.Method = "post";
myReq.ContentLength = byData.Length;
Stream reqStrem = myReq.GetRequestStream();
reqStrem.Write(byData, 0, byData.Length);
reqStrem.Close();
HttpWebResponse result = (HttpWebResponse)myReq.GetResponse();
Stream recStream = result.GetResponseStream();
//如果是Gzip方式則需要解壓
recStream = new GZipStream(recStream, CompressionMode.Decompress);
StreamReader redStream = new StreamReader(recStream, System.Text.Encoding.Default);
string strHTML = redStream.ReadToEnd();
redStream.Close();
recStream.Close();
result.Close();
return strHTML;
}
catch (Exception)
{
return "";
}
}
