main.js调用

import { fetch, post, patch, put } from '@/util/fetch'

Vue.prototype.get = fetch
Vue.prototype.post = post
Vue.prototype.patch = patch
Vue.prototype.put = put

视图页面使用 

export default {
  name: 'login',
  data () {
    return {
      mobile: '',
      password: ''
    }
  },
  components: {
    XInput,
    XButton,
    Group,
    Box
  },
  methods: {
    handleLogin () {
      let params = {}
      params.username = this.mobile
      params.password = this.password
      this.post('/api/driver/index', params).then((data) => {
        console.log(data)
      }).catch((error) => {
       console.log(error)
      })
    }
  }
}
