在 VueJS 组件中,将 vuex getter 映射到不同的名称不起作用

In VueJS component mapping vuex getters to a different name not working

computed: {
  ...mapGetters('global/train_ticket', [
    { ticketTypeForTrain: 'getTicketType' },
    { ticketFareForTrain: 'getTicketFare' },
  ]),
},
mounted() {
  console.log(this.ticketTypeForTrain + ' ' + this.ticketFareForTrain)
},

在上面的代码中,我已经明确命名了 getter。当我试图在 mounted 钩子中获取它们时,我得到 undefined undefined

如果我不明确命名它们,我可以获取如下值

computed: {
  ...mapGetters('global/train_ticket', [
    'getTicketType', 'getTicketFare'
  ]),
},
mounted() {
  console.log(this.getTicketType+ ' ' + this.getTicketFare)
}

为什么命名 getter 不起作用?

谢谢

docs 中所示:

如果要将 getter 映射到其他名称,请使用对象

因此您的代码应该使用对象而不是数组,如下所示:

computed: {
  ...mapGetters('global/train_ticket', {
     ticketTypeForTrain: 'getTicketType',
     ticketFareForTrain: 'getTicketFare',
  }),
},
mounted() {
  console.log(this.ticketTypeForTrain + ' ' + this.ticketFareForTrain)
},
