How to add Authorization header with Retrofit2 + RxJava

Question

I want to perform request using Retrofit2 and RxJava

public static Observable<Post> getPostsAround(Location location, int offset, int limit) {
    if(api==null) {
        new RestService();  //initialize API in constructor
    }
    return api.getPostsAround(location.getLatitude(),location.getLongitude(),offset,limit)
            .flatMapIterable(posts -> posts);   //transform Observable<List<Post>> to Observable<Post> which emits posts onNext
}

I tried @Headers("Authorization: code) annotation, but I don't know how to change "code" in runtime.

我找到了答案： 可以使用@Header注释动态更新请求标头。必须为@Header提供相应的参数。如果该值为null，则将省略标头。否则，将在值上调用toString，并使用结果。

@GET("user")
Call<User> getUser(@Header("Authorization") String authorization)
