问题描述
Retrofit 2 的文档 说:
可以使用 OkHttp 拦截器指定需要添加到每个请求的标头.
Headers that need to be added to every request can be specified using an OkHttp interceptor.
使用以前的版本可以轻松完成，这里是相关的QA.
It can be done easily using the previous version, here's the related QA.
但是使用改造 2，我找不到类似 setRequestInterceptor 或 setInterceptor 方法可以应用于 Retrofit.Builder 对象.
But using retrofit 2, I couldn't find something like setRequestInterceptor or setInterceptor method that can be applied to Retrofit.Builder object.
另外，OkHttp 中似乎没有 RequestInterceptor 了.Retrofit 的文档将我们引向 Interceptor 我不太明白如何使用它目的.
Also it seems that there's no RequestInterceptor in OkHttp anymore. Retrofit's doc refers us to Interceptor that I didn't quite understand how to use it for this purpose.
我该怎么做?
推荐答案
OkHttpClient.Builder httpClient = new OkHttpClient.Builder();
httpClient.addInterceptor(new Interceptor() {
@Override
public Response intercept(Chain chain) throws IOException {
Request request = chain.request().newBuilder().addHeader("parameter", "value").build();
return chain.proceed(request);
}
});
Retrofit retrofit = new Retrofit.Builder().addConverterFactory(GsonConverterFactory.create()).baseUrl(url).client(httpClient.build()).build();
