POST请求

GET请求

子线程中调用

必须在子线程中调用

new Thread(new Runnable() {
                    @Override
                    public void run() {

                        HttpConnection.connectGET("111","222");
                       // HttpConnection.connectionPost("111","222");
                    }
                }).start();
