使用HttpURLConnection发送短信

public int sendMobile(String receiveMobile, String content) {
/**设置短信参数**/
String msg_ip = "";

String msg_company_id = "";

msg_ip = Config.MSG_IP;
msg_user_id = Config.MSG_USER_ID;
msg_company_id = Config.MSG_COMPANY_ID;
    msg_pwd = Config.MSG_PWD;
    msg_key = Config.MSG_KEY;
    
/**发动短信动作**/
try {
content =  URLEncoder.encode(content+msg_key, "utf-8"); 
System.out.println(content);
String url  = msg_ip+"corporateid="+msg_company_id+"&userid="+msg_user_id+"&password="+msg_pwd+"&mobile="+receiveMobile+"&content="+content+"&schtime=&subcode=";
URL urls = new URL(url); 
HttpURLConnection connection = (HttpURLConnection) urls.openConnection();

connection.connect(); 
BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream(),"utf-8"));//
String lines; 
    while ((lines = reader.readLine()) != null){ 
        //lines = new String(lines.getBytes(), "utf-8");
