 * 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.
