    data
  })
}

组件部分

//我是login组件
<template>
  <div class="login">

  },
  methods: {
    async register () {
      let { status, message } = await this.$store.dispatch('register', this.$qs.stringify({'mobile': this.form.mobile, 'password': this.form.password}))//把mobile和password输入的值传给actions
      if (status === 'fail') {
        console.log(message)
        return false
      } //固定写法
      this.uid = sessionStorage.getItem('uid') //本地存储uid
