vue判断微信登录公众号退出登录

微信公众号退出问题
1、判断是否是微信端登录

main.js 

Vue.prototype.isWx = () => {
  let ua = navigator.userAgent.toLowerCase()
  return (/micromessenger/.test(ua))
}

2、退出按钮

logout () {
  let vm = this
  this.$http.get(this.base + 'logout?token=' + this.$store.getters.get_token).then(res => {
    if (res.data.code === 200) {
      if (vm.isWx()) {
        this.$store.commit('set_token', '')
        location.assign('https://')  // 微信登录地址
        this.showOut = false
      } else {
        this.$store.commit('set_token', '')
        this.$router.push('/')
        this.showOut = false
      }
    } else {
    }
  }).catch(err => {
    console.log(err)
  })
}
