点击"我知道了"按钮,调用封装_getuserinfo的请求
新建config.js,在config封装请求

vuex存储登录态的方法


import Vue from 'vue'
import Vuex from 'vuex'

Vue.use(Vuex)

const store = new Vuex.Store({
  state: {
    hasLogin: false,
    userinfo: {},
    ppid: '',
  },
  mutations: {
    // 登录
    login(state,res) {
      state.hasLogin = true
      state.userinfo = res
      uni.setStorage({
        key: 'userinfo',
        data: res
      })
      // console.log(state.userinfo)
      // console.log(state.hasLogin)
    },
    // 二维码ppid
    saveppid(state,ppid) {
      state.ppid = ppid
      uni.setStorage({
        key: 'ppid',
        data: ppid
      })
      // console.log(state.ppid)
    },
  },
})

export default store
