添加标题到所有请求与改造2

问题描述

说：

它可以可以使用以前的版本轻松完成，中没有 RequestInterceptor 了。 Retrofit的文档指向我们，我不太明白如何使用它

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？

How can I do this?

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();
