HTTP在C＃插座 [英] HTTP over C# sockets

问题描述

我试图发送HTTP请求，并从该服务器在C＃插座收到的反响，我用新的这种语言。

I am trying to send HTTP request and recieve responce from the server over C# sockets, and i'm new with this language.

我已经写了下面的代码（IP正确解析）：

I've wrote following code (IP resolved correctly):

IPEndPoint RHost = new IPEndPoint(IP, Port);
Socket socket = new Socket(AddressFamily.InterNetwork, SocketType.Stream, ProtocolType.Tcp);
socket.Connect(RHost);

String HTTPRequestHeaders_String = "GET ?q=fdgdfg HTTP/1.0
Host: google.com
Keep-Alive: 300
Connection: Keep-Alive
User-Agent: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/534.16 (KHTML, like Gecko) Chrome/10.0.648.205 Safari/534.16
Referer: http://google.com/";

MessageBox.Show(HTTPRequestHeaders_String, "Request");

byte[] HTTPRequestHeaders = System.Text.Encoding.ASCII.GetBytes(HTTPRequestHeaders_String);
socket.Send(HTTPRequestHeaders, SocketFlags.None);

String Response = "";
byte[] buffer = new byte[(int) socket.ReceiveBufferSize];

int bytes;
do
{
    // On this lane program stops to react
    bytes = socket.Receive(buffer);
    // This line cannot be reached, tested with breakpoint
    Response += Encoding.ASCII.GetString(buffer, 0, bytes);
}
while (bytes >= 0);

MessageBox.Show(Response, "Response");

我究竟做错了什么？我只需要加载页面的完整HTML，或响应至少几个字符（我不能做，即使这一点）。

What am i doing wrong? I need just to load full HTML of page, or at least few characters from response (i cant do even this).

推荐答案

// WWW：如果你想这样做原材料， HTTP我会建议寻找到协议本身。 w3.org/Protocols/HTTP/1.0/spec.html#Request

I would suggest looking into the protocol itself if you want to do this raw, http://www.w3.org/Protocols/HTTP/1.0/spec.html#Request

和尝试发送CRLF终止请求;）

And try sending the CRLF to terminate the request ;)
