如何在retrofit2中获取json

implementation 'com.squareup.retrofit2:retrofit:2.x.x'
implementation 'com.squareup.retrofit2:converter-gson:2.x.x'

public interface ApiService {
    @GET("your_api_endpoint")
    Call<JsonObject> getJsonData();
}

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl("your_base_url")
        .addConverterFactory(GsonConverterFactory.create())
        .build();

ApiService apiService = retrofit.create(ApiService.class);

apiService.getJsonData().enqueue(new Callback<JsonObject>() {
    @Override
    public void onResponse(Call<JsonObject> call, Response<JsonObject> response) {
        if (response.isSuccessful()) {
            JsonObject jsonData = response.body();
            // 处理获取到的JSON数据
        } else {
            // 处理请求失败的情况
        }
    }

    @Override
    public void onFailure(Call<JsonObject> call, Throwable t) {
        // 处理请求失败的情况
    }
});
