Application and implementation of data cache mechanism for small programs

// Save data cache wx.setStorage({
  key: 'key', // The key specified in the local cache
  data: 'value', // content to be stored (supports object or string)
  success: res => {}, // callback function for successful interface call	
  fail: res => {} // callback function for interface call failure})

// Get data cache wx.getStorage({
  key: 'key', // The key specified in the local cache
  success: res => { // Callback function of successful interface call console.log(res.data)
  }, 
  fail: res => {} // callback function for interface call failure})

// pages/test/test.js
Page({
  onLoad: function(options) {
    // Save data cache wx.setStorage({
      key: 'key', // The key specified in the local cache
      data: 'value', // content to be stored (supports object or string)
      success: res => {
        // Get data cache wx.getStorage({
          key: 'key', // The key specified in the local cache
          success: res => { // Callback function of successful interface call console.log(res.data)
          },
          fail: res => { } // callback function for interface call failure})
      }, // callback function for successful interface call fail: res => {} // callback function for failed interface call })
  }
