Retrofit 2/Rxjava - retrieve headers from response

Question

@GET("/city/{cityId}/category/all")
Observable<MyDictionary> getDictionaries(@Path(value = "cityId", encoded = true) String cityId, @HeaderMap Map<String, String> headers);

Call method to retrieve data:

service.getDictionaries(cityId, headersMap)
                .subscribeOn(Schedulers.io())
                .observeOn(AndroidSchedulers.mainThread())
                .subscribe(resp ->
                {
                     /*...............*/

                }, throwable ->
                {
                     /*...............*/
                });

I can get reposne eaisly. But I also need to know response headers. How to access them in my code? Any tips? I'm getting only body, how to get headers also?

Answer 1

You can get response headers this way:

Set response type as Observable<Response<MyDictionary>> as following:

In Service Interface:

@GET("/city/{cityId}/category/all")
Observable<Response<MyDictionary>> getDictionaries(@Path(value = "cityId", encoded = true) String cityId, @HeaderMap Map<String, String> headers);

and while calling api: you would be able to get headers by :

response.getHeaders() method.
