OkHttpClient 如何添加Header；如果在header添加token

1、代码

OkHttpClient client = new OkHttpClient().newBuilder()
                .build();
        Request request = new Request.Builder()
                .url(url)
                .method("GET", null)
                .addHeader("Authorization", token)
                .addHeader("Accept", "application/json;odata=verbose")
                .build();
