Java http方式提交短信到短信网关

URL url = new URL("短信网关url"); 一般短信内容需要用URLEncoder.encode()编码一下
HttpURLConnection httpCon = (HttpURLConnection) url.openConnection();
httpCon.connect();
BufferedReader in = new BufferedReader(new InputStreamReader(httpCon.getInputStream()));
String line = in.readLine();
System.out.println(" </p>result:" + line);
int i_ret = httpCon.getResponseCode();
String sRet = httpCon.getResponseMessage();
System.out.println("sRet is:" + sRet);
System.out.println("i_ret is:" + i_ret);
