WeChat Mini Program API Data Cache

Each WeChat applet can have its own local cache, which can be set through wx.setStorage (wx.setStorageSync), wx.getStorage (wx.getStorageSync), wx.clearStorage (wx.clearStorageSync) , get and clean.

Note: localStorage is permanently stored, but we do not recommend storing all key information in localStorage to prevent users from changing devices.
