Microservices BFF Authentication (Sa-Token Authentication and Authorization)

Clients do not directly access the public APIs of the server. Instead, they call the APIs provided by the BFF layer, which then invokes the underlying services. Different clients have their own BFF layers, allowing API interfaces to be customized according to each client's requirements. With the BFF layer, clients only need to initiate a single HTTP request. The BFF layer can then call different services and return the aggregated data to the client. This reduces the number of external HTTP requests and improves response speed.
