retrofit没有得到JSON对象的id

它成功获得名称,状态和登录信息。但它将0分配给u_id(用户ID),它应该是4.也许它可以将Id作为Json的字符串获取?我不知道整数的正确JSON格式。

JSON:

{
  "id": "4",
  "name": "nuku",
  "status": "1",
  "login": "sucess"
}

POJO: 公共类LoginModel {

    @Expose
    public static int id;

    @Expose
    public String name;

    @Expose
    private String status;
    @Expose
    private String login;
...}

接口:

   String url = "http://192.168.10.5/tourist/v1";
    @FormUrlEncoded
    @POST("/login")
    void Login(@Field("email") String email,
               @Field("pass") String pass, Callback<LoginModel> cb);
}

改装功能调用:

RestAdapter adapter = new RestAdapter.Builder().setEndpoint(RestInterface.url).build();

                    //Creating Rest Services
                    final RestInterface restInterface = adapter.create(RestInterface.class);

                    //Calling method to get check login
                    restInterface.Login(email.getText().toString(), pass.getText().toString(), new Callback<LoginModel>() {
                        @Override
                        public void success(LoginModel model, Response response) {

                            //finish();
                            //startActivity(getIntent());

                            email.setText("");
                            pass.setText("");

                                 int id = model.getUserId();
                            if (model.getStatus().equals("1")) {  //login Success

                                SharedPreferences sharedPreferences = getSharedPreferences("MyLogin.txt", Context.MODE_PRIVATE);
                                SharedPreferences.Editor editor = sharedPreferences.edit();
                                editor.putBoolean("FirstLogin", true);
                                editor.commit();



                                Toast.makeText(LoginActivity.this, "Login In SuccessFully"+model.getUserId(), Toast.LENGTH_SHORT).show();

                                manager.setPreferences(LoginActivity.this, "status", "1");
                                String status=manager.getPreferences(LoginActivity.this,"status");

                                Intent i = new Intent(LoginActivity.this,MainActivity.class);


                                String name = model.getUser_name();
                                i.putExtra("username", name);
                               // String image = p.getPlace_image();
                               // i.putExtra("Thumbnail", image);
                                i.putExtra(MainActivity.EXTRA_USER,"username");
                                startActivity(i);



                              //  String nameStr = email.getText().toString();

                                // i.putExtra("text1", nameStr);
                                //startActivity(i);

                            } else if (model.getStatus().equals("0"))  // login failure
                            {
                                Toast.makeText(LoginActivity.this, "Invalid UserName/Pass ", Toast.LENGTH_SHORT).show();
                                Intent i = new Intent(LoginActivity.this, LoginActivity.class);
                                startActivity(i);

                            }
                        }

                        @Override
                        public void failure(RetrofitError error) {
                            finish();
                            startActivity(getIntent());
                            String merror = error.getMessage();
                            Toast.makeText(LoginActivity.this, merror, Toast.LENGTH_LONG).show();
                        }
                    });
                }

您的LoginModel不正确或发送JSON的人没有正确执行。 JSON中的ID是字符串,而不是整数(注意双引号)

您必须在LoginModel中将ID类型更改为String,但是,IMO,更好的解决方案是将其作为整数接收。

这是一个带有Integer的JSON示例:

{
 "email":"some@email.com",
 "age":25,
 "man":true,
 "password":"123456"
}

我尝试将Id作为字符串,但改装为其分配了null,因此我只使用此echo json_encode将我的JSON转换为整数($ output,JSON_NUMERIC_CHECK);它工作了!
