retrofit2：添加 RequestInterceptor

Question

伙计们，请尝试从 retrofit 1 升级到 retrofit 2，但是我很难为所有请求添加请求拦截器. 在 retrofit 1 中，我通过这样做实现了它；

public static <S> S createService(Class<S> serviceClass, final String token) {
    RestAdapter.Builder builder = new RestAdapter.Builder()
            .setEndpoint(Constant.APP_URL);
    builder.setRequestInterceptor(new RequestInterceptor() {
        @Override
        public void intercept(RequestFacade request) {
            request.addHeader("token", token);
        }
    });
    RestAdapter adapter = builder.build();

    return adapter.create(serviceClass);
}

但我无法在 retrofit 2 中解决这个问题...请问有人能解决我的问题吗？

Answer 1

在你的依赖块中添加：

compile 'com.squareup.okhttp3:logging-interceptor:3.2.0'

在您的 Retrofit 服务中 class 添加：

    HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
    interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
    OkHttpClient client = new OkHttpClient.Builder()
            .addInterceptor(interceptor)
            .build();

然后添加：

    Retrofit retrofit = new Retrofit.Builder()
            .baseUrl(URL)
            .client(client) // this is the line you care about
            .addCallAdapterFactory(RxJavaCallAdapterFactory.create())
            .addConverterFactory(JacksonConverterFactory.create())
            .build();
