　get方式：

 1 public static void requestNetForGetLogin(final Context context,final Handler handler ,final String username, final String password) {
 2                 //使用HttpClient请求服务器将用户密码发送服务器验证
 3                 try{
 4                 String path = "http://192.168.13.83:8080/xuexi/servlet/LoginServlet?username="+URLEncoder.encode(username,"utf-8")+"&pwd="+URLEncoder.encode(password,"utf-8");
 5         
 6                 //创建一个AsyncHttpClient对象
 7                 AsyncHttpClient asyncHttpClient = new AsyncHttpClient();
 8                 asyncHttpClient.get(path, new AsyncHttpResponseHandler() {

12                         //statusCode:状态码    headers：头信息  responseBody：返回的内容，返回的实体
13                         //判断状态码
14                         if(statusCode == 200){
15                             //获取结果
