如何在 Retrofit2 中使用 jsonapi？

Question

我需要在改造 2 中使用 jsonapi。我尝试使用moshi-jsonapi，但我无法使用 moshi ConverterFactory。

TokenModel.java

@JsonApi(type = "tokens")
public class TokenModel extends Resource {
    @Json(name = "cell_phone")
    public String cellPhone;
}

TestService.java：

public interface TestService {
    @POST("token")
    Call<TokenModel> newOtp(@Body TokenModel tokenModel);
}

TestProvider.java：

public class TestProvider {
    private TestService testService;

    public TestProvider() {
        OkHttpClient httpClient = new OkHttpClient();
        Retrofit refRetrofit = new Retrofit.Builder()
                .baseUrl(ClientConfigs.BASE_URL)
                .client(httpClient)
                .addConverterFactory(MoshiConverterFactory.create())
//                .addConverterFactory(????????????????????????????)
                .build();
        testService = refRetrofit.create(TestService.class);
    }

    publicTestService getTestService() {
        return testService;
    }
}

如果我使用MoshiConverterFactory 会报错Unable to create converter for class com.xxx.xxx.model.TokenModel！

使用改造：

TsetProvider testProvider = new TestProvider();
TestService testService = testProvider.getTestService();

TokenModel tokenModel = new TokenModel();
tokenModel.cellPhone = "121212129999";

Call<TokenModel> call = testService.newOtp(tokenModel);
call.enqueue(new Callback<TokenModel>() {
    @Override
    public void onResponse(Call<TokenModel> call, Response<TokenModel> response) {
    }

    @Override
    public void onFailure(Call<TokenModel> call, Throwable t) {
    }
});

从moshi-jsonapi 文档中，您需要将库工厂添加到 moshi 实例：

// First create the factory
JsonAdapter.Factory jsonApiAdapterFactory = ResourceAdapterFactory.builder()
  .add(TokenModel.class)
  .build();

// Create a custom moshi instacne
Moshi moshi = new Moshi.Builder()
  .add(jsonApiAdapterFactory)
  .build();

// Add the custom moshi instance to Retrofits Converter Factory
Retrofit refRetrofit = new Retrofit.Builder()
  .baseUrl(ClientConfigs.BASE_URL)
  .client(httpClient)
  .addConverterFactory(MoshiConverterFactory.create(moshi))
  .build();

这应该可以解决问题。
