java - 改造2:添加RequestInterceptor

Question

伙计们，请尝试从retrofit 1升级到retrofit 2，但我很难为所有请求添加请求拦截器。在 retrofit 1 中，我通过做这样的事情来实现它；

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);
}

但是我在retrofit 2中无法解决这个问题...请问有人可以解决我的问题吗？

Answer 1

在您的依赖项 block 中添加:

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

在您的Retrofit服务类中添加:

    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();
