如何在翻新Android中使用get方法傳遞json數組

Question

我是新手，不知道如何使用改造傳遞此json並在我的應用中顯示。下面是我的json，MainActivity和模型類。但是知道它拋出異常“除了begin_object但找到begin_array”。請幫我。

[
    {
        "userId": 1,
        "id": 1,
        "title": "sunt",
        "body": "sdfdsf"
      },
      {
        "userId": 1,
        "id": 2,
        "title": "qui est esse",
        "body": "jhmjk"
      }]

MainActivity.java

Retrofit retrofit = new Retrofit.Builder()
                .baseUrl(BASE_URL)
                .addConverterFactory(GsonConverterFactory.create())
                .build();
        ApiInterface apiService = retrofit.create(ApiInterface.class);
        // ApiInterface apiService = ApiClient.getClient().create(ApiInterface.class);
        Call<ModelClass> call = apiService.getLogin();
        // Call<LoginResponse> call = apiService.loginWithCredentials(new LoginRequest(email_enter, md5pass));
        call.enqueue(new Callback<ModelClass>() {
            @Override
            public void onResponse(Call<ModelClass> call, Response<ModelClass> response) {
                Log.i("REGISTRATION --->", "Registered" + response);
            }

            @Override
            public void onFailure(Call<ModelClass> call, Throwable t) {
                Log.i("REGISTRATION --->", "Throwable" + t.toString());
                // Intent i = new Intent(MainActivity.this,SecondActivity.class);
                // startActivity(i);
            }
        });
    }

ModelClass.java

public class ModelClass {
    class Model{
        public List<ObjectModel> getObjectmodel() {
            return objectmodel;
        }

        public void setObjectmodel(List<ObjectModel> objectmodel) {
            this.objectmodel = objectmodel;
        }

        List<ObjectModel> objectmodel;
    }

    class ObjectModel{
        String userId;
        String id;

        public String getTitle() {
            return title;
        }

        public void setTitle(String title) {
            this.title = title;
        }

        public String getUserId() {
            return userId;
        }

        public void setUserId(String userId) {
            this.userId = userId;
        }

        public String getId() {
            return id;
        }

        public void setId(String id) {
            this.id = id;
        }

        public String getBody() {
            return body;
        }

        public void setBody(String body) {
            this.body = body;
        }

        String title;
        String body;
    }
}

Answer 1

創建自定義模型並在改造API中傳遞相同模型。

class Model{
   List<ObjectModel> objectmodel;
 }

class ObjectModel{
   String userId;
   String id;
   String title;
   String body;
}

在改造界面中綁定值並傳遞Model對象。

要么

@GET("json")
Call<JsonObject> youmethode(@Query("key") String value);

希望這會有所幫助。 謝謝

要傳遞json請求，您必須使用post方法。
