How to do a user authentication using the standard API Gateway ? I've read a lot of articles but I do not find a code example using Web API 2 and the ones I saw using the net core in> only does the first authentication of the user, that is, as it is the context of the user logged in the "internal" microservices , follows scenario:
- Sales Microservice
- Inventory Microservice
Imagine that users can access both microservices and each user has an account identified with a Guid, my question is how "Api Gateway" authenticates the user and mounts the context of it that the internal microservices can identify which resources it has access to.
