How to get refresh token from the Identity server.

I was struggling to get refresh token along with the access token with user credential(username and password) while accessing the IdentityServer 4.Finally I could generate the successful response as a result of my hard work. If you need refresh token from the identityserver 4 you must set the below configurations to the Memory clients which are using in the application.

I know some of you have the doubt about  Memory clients😐  you are using memory client class in   ConfigureServices method in the start up file as below screenshot.

in there you have to set AllowedScopes to  IdentityServerConstants.StandardScopes.OfflineAccess as below.

Now you are finish with the configuration and you can try this using Postman(this could be your choice 😛) as below.

 Once you have the refresh token in you hand it is very easy to get access token instead of set session timeout therefore user won't feel inconvenience while using the application and finally application will be a secure to trust.

  you can set expiration to the token as your preferences.
Enjoy,
Happy coding 💪
