1:用jdk连接
String action = "xxxxxxxxxxx";
URL url = new URL(action);
HttpURLConnection http = (HttpURLConnection) url.openConnection();
http.setRequestMethod("POST");
http.setConnectTimeout(0);
http.setInstanceFollowRedirects(true);
http.setRequestProperty("Content-Type",
"application/x-www-form-urlencoded");
http.setDefaultUseCaches(false);
http.setDoOutput(true);
String queryString = "";
PrintWriter out = new PrintWriter(http.getOutputStream());
out.print(queryString);//传入参数
out.close();
http.connect();//连接
InputStream in = httpURLConnection.getInputStream();
