get方法呼叫演示

UserEntity 是使用者實體，這裡就不給出了

url連結如果不是http開頭，那麼會使用httpBase裡面的url地址

public class LoginHttp extends HttpBase {
//使用時呼叫此方法
    public void login(Handler handler, String username, String password) {
        String url = "/api/user/login?username="+username+"&password="+password;
        super.HttpGet(url, handler, 0x200);
    }
//處理返回資料
    @Override
    public void sendMessage(String reStr) {
        UserEntity userEntity = new UserEntity();
        try {
            JSONObject jsonObject = new JSONObject(reStr);
            int code = jsonObject.getInt("code");
            userEntity.setCode(code);
            userEntity.setMsg(jsonObject.getString("msg"));
            if (code == 1000) {
                userEntity.setUsername(jsonObject.getString("username"));
                userEntity.setPhone(jsonObject.getString("phone"));
            }

        } catch (JSONException e) {
            e.printStackTrace();
        }
        super.messages(userEntity);
    }
}
