无法通过代理提出请求

Question

我想通过代理提出请求。这没有代理，工作正常：

Socket sock = new Socket("example.com", 80);
OutputStream oStream = sock.getOutputStream();

//Writing headers to send to the proxy

String request = rType + " " + uri + " HTTP/1.0";
oStream.write(request.getBytes());
oStream.write(endOfLine.getBytes());

String cmd = "host: "+ header.get("host");
oStream.write(cmd.getBytes());
oStream.write(endOfLine.getBytes());
System.out.println(cmd);

//............................

但是，使用代理服务器，这种情况并不顺利，它会挂起：

Proxy prx = new Proxy(Proxy.Type.SOCKS, new InetSocketAddress("my proxy ip address", 1234)); // predefined ip and port
sock = new Socket(prx);
sock.connect(new InetSocketAddress("example.com", 80)); //hangs here
oStream = sock.getOutputStream();

//............................

该怎么做？

正如@MrSimpleMind已说明：使用Proxy.Type.HTTP代替Proxy.Type.SOCKS。
