okhttp中简单的过滤器添加头部信息

public class HeaderInterceptor implements Interceptor {

    @NotNull

    @Override

    public Response intercept(@NotNull Chain chain) throws IOException {

        //通过chain.request();拿到一个request

         Request request = chain.request();

        //得到当前request构造的对应的Builder对象

         Request newrequest = request.newBuilder()

                .addHeader("author", "hyx_interceptor")

                .build();

        return chain.proceed(newrequest);//proceed继续往下的意思

    }

}

然后在okhttp的

OkHttpClient.Builder()

.addInterceptor(new HeaderInterceptor())

.build();

来添加
