根据 vuex 的 this.$store.dispatch() 返回值处理逻辑

1. App.vue

        const ret = await this.$store.dispatch('userLogin', {
          username: this.curUserName,
          password: this.curPassword
        })
        if (ret && ret.info) {
          this.$message.success(ret.info)
          await this.$store.dispatch('controlLoginDialog', false)
        } else {
          this.$message.warning(ret)
        }

2. vuex/store/action.js

  async userLogin ({commit}, account) {
    let userInfo = {}
    return new Promise((resolve, reject) => {
      requestUserLogin(account).then(response => {
        if (response.status === 200) {
          if (response.data.data) {
            userInfo = response.data.data
            userInfo.userName = userInfo.name
            userInfo.isLogin = true
            resolve({
              info: userInfo.userName + ' 登录成功，欢迎进入百度云智学院实验平台'
            })
          } else if (response.data.fail) {
            userInfo.userName = ''
            userInfo.isLogin = false
            myConsole('response.data.fail')
            resolve(response.data.fail)
          }
        } else {
          userInfo.userName = ''
          userInfo.isLogin = false
        }

        commit(USER_LOGIN, {userInfo})
      }).catch(err => {
        myConsole(err)
        reject(err)
      })
    })
  },
