android - 改造 - 全局拦截响应

Question

我想拦截改造引擎收到的所有响应，并扫描 HTTP 错误代码，例如错误 403。

我知道我可以使用每个请求的失败(RetrofitError 错误)回调并检查 403，但我想全局包装响应。

我可以看到请求拦截是可能的，但我没有看到类似的响应选项。

有什么建议吗？

我能够通过向改造正在使用的 OkHttpClient 添加一个拦截器来实现这一点。

Kotlin + 改造 2.x

val clientBuilder = OkHttpClient.Builder()
clientBuilder.addInterceptor { chain ->
            val request = chain.request()
            val response = chain.proceed(request)
            if (response.code() == 403) {
                handleForbiddenResponse()
            }
            response
        }

改造 2.x:

   OkHttpClient.Builder clientBuilder = new OkHttpClient.Builder();
   clientBuilder.
            addInterceptor(new Interceptor() {
                @Override
                public Response intercept(Chain chain) throws IOException {
                   Request request = chain.request();
                   Response response = chain.proceed(request);
                   if (response.code() == 403) {
                         handleForbiddenResponse();
                   }
                   return response;
                }
            });


    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(API_BASE_URL)
            .addConverterFactory(GsonConverterFactory.create())
            .client(clientBuilder.build();)
            .build();

改造 1.x:

public class ForbiddenInterceptor implements Interceptor {

    @Override
    public Response intercept(Chain chain) throws IOException {
        Request request = chain.request();
        Response response = chain.proceed(request);
        if (response.code() == 403) {
             handleForbiddenResponse();
        }
        return response;
    }
}



OkHttpClient okHttpClient = Utils.createUnsafeOkHttpClient();
okHttpClient.interceptors().add(new ForbiddenInterceptor());

RestAdapter.Builder restAdapterBuilder = new RestAdapter.Builder()
        .setEndpoint(API_BASE_URL)
        .setClient(new OkClient(okHttpClient));
