Front Gateway Trampling Practice
Project BackgroundIn back-end microservices, it is common to expose a unified gateway entry to the outside world, which enables the whole system services to have a unified entry and exit, and converge services. However, the front-end services which provide gateway entries and exits in a unified way are relatively rare, and often each applicatio ...
