没有pojo的改造和GSON

Question

我在应用程序中使用黑客新闻api。 我想使用gson工厂转换器进行改造调用，但是我无法将响应转换为pojo，因为它只是整数列表。

以下是api调用和响应

Answer 1

PoJo代表Plain Old Java Objects，如果您得到一个整数数组作为响应，请在改造接口中对其进行解析，

像这样的东西：

@GET(... you url)
Call<List<Integer>>getHackerNews()

期望有一个整数数组或列表。

Answer 2

首先创建这样的界面....

public interface GitHubService {
        @GET("v0/topstories.json")
        Call<List<Long>> listRepos();
    }

并在这样的活动中使用.....

        Retrofit retrofit = new Retrofit.Builder()
                .baseUrl("https://hacker-news.firebaseio.com/").addConverterFactory(GsonConverterFactory.create())
                .build();

        GitHubService api = retrofit.create(GitHubService.class);

        api.listRepos().enqueue(new Callback<List<Long>>() {
            @Override
            public void onResponse(Call<List<Long>> call, Response<List<Long>> response) {
                if (response.isSuccessful()) {

                    // do operations here 
                    String number = "";
                    for (int i = 0; i < response.body().size(); i++)
                        number += response.body().get(i) + ", ";

                    ((TextView) findViewById(R.id.number)).setText(number);
                } else
                    Toast.makeText(MainActivity.this, response.errorBody().toString(), Toast.LENGTH_LONG).show();
            }

            @Override
            public void onFailure(Call<List<Long>> call, Throwable t) {
            Toast.makeText(MainActivity.this, t.getMessage().toString(), Toast.LENGTH_LONG).show();
            }
        });

并在您的gradle中使用这种关系...

>    compile 'com.squareup.retrofit2:retrofit:2.3.0'
>     compile 'com.squareup.retrofit2:converter-gson:2.+'

Answer 3

请确保将响应包装在ResponseBody中，如下所示：

@GET(your url param)
Call<ResponseBody>getNews();

上面的Responsebody将返回响应，然后您可以使用下面的Statement使用此ResponseBody将其转换为JSONArray或JSONObject

JSONArray jsonArray=new JSONArray(ResponseBody.body().String())
