Android中的Http通信doPost和doGet方式

//得到关于Android系统相关信息例如 file encodeing=utf-8
Properties property = System.getProperties();
property.list(System.out);

private void doPost() {

            OutputStream out = conn.getOutputStream();
            String content = "name=" + name + "&age=" + age ;
            //Android系统自动编码
            out.write(content.getBytes());
            BufferedReader reader = new BufferedReader(new InputStreamReader(conn.getInputStream()));
            StringBuffer sb = new StringBuffer();
