There is one more hint that not in this conversation  for asp net core 3 1 first add the key that you need to put it in the header  something like this  Response Headers Add  quot your-key-to-use-it-axios quot    quot your-value quot     where you define the cors policy  normaly is in Startup cs  you should add this key to WithExposedHeaders like this            services AddCors options   gt                    options AddPolicy  quot CorsPolicy quot               builder   gt  builder                  AllowAnyHeader                    AllowAnyMethod                    AllowAnyOrigin                    WithExposedHeaders  quot your-key-to-use-it-axios quot                        you can add all the keys here  now in your client side you can easily access to the your-key-to-use-it-axios by using the response result            localStorage setItem  quot your-key quot   response headers  quot your-key-to-use-it-axios quot      you can after use it in all the client side by accessing to it like this  const jwt   localStorage getItem  quot your-key quot
