v3.9.0

• Add mock.js to instead of easy-mock

This project originally used easy-mock to simulate data,but its official service is very unstable, and you can build your own service if you need it.

So here I use Mock.js for local emulation, it will intercept your request, so you won't see the request in the network.

If you remove ../mock it will automatically request easy-mock data.
