Vue axios 承诺范围未绑定到当前组件

Vue axios promise scope is not binding to current component

如何在方法对象中绑定函数。我相信如果我使用箭头函数,它应该会自动绑定当前对象。但是,它有自己的范围。因此,我无法在 http get 请求后更新数据变量。

这是我的客户组件。

 import axios from 'axios';

  export default {
    data () {
      return {
        customers: 'temp ',
        loading: 'false',
        error: null,
      }
    },
    created () {
      console.log(this)//this is fine 
      this.getCustomerList()
    },
    watch: {
      '$route': 'getCustomerList'
    },

    methods: {
      getCustomerList: () => {
        console.log(this)
        axios.get('/api/customers')
        .then((res)=>{
          if(res.status === 200){
          }
        })
      }
    }
  }

这是 console.log(this)..

的结果

这是我的 app.js 文件

import Vue from 'vue'
import VueRouter from 'vue-router'
Vue.use(VueRouter)

import Customers from './components/Customers/Customers.vue'

const router = new VueRouter({
  mode: 'history',
  base: __dirname,
  history: true,
  routes: [
    { path: '/customers', component: Customers }
  ]
})

new Vue ({
  router
}).$mount('#app')

尝试以下操作:

methods: {
  getCustomerList () {
    console.log(this)
    var that = this
    axios.get('/api/customers')
    .then((res)=>{
      if(res.status === 200){
          //use that here instead of this
      }
    })
  }
}
