标签: laravel-5 vue.js axios

最近我完成了本教程:https://github.com/Hujjat/laravStart 在这个应用程序中,我可以成功运行vuejs应用程序和axios.then.catch.finally或this.form.then.catch.finally 但我在最近升级到laravel 5.7的旧项目中添加了npm。 在我的应用程序中,我无法最终添加功能。如果我这样做,它说:

  

未捕获的TypeError:axios.post(...)。then(...)。catch(...)。最终是   不是功能

我的app.js:

/**
 * First we will load all of this project's JavaScript dependencies which
 * includes Vue and other libraries. It is a great starting point when
 * building robust, powerful web applications using Vue and Laravel.
 */

// require('./bootstrap');
import Vue from 'vue'
window.Vue = Vue
window.axios = require('axios');
import { Form, HasError, AlertError } from 'vform'
window.Form = Form;




Vue.component(HasError.name, HasError)
Vue.component(AlertError.name, AlertError)

Vue.component('pagination', require('laravel-vue-pagination'));
//select 2
import vSelect from 'vue-select'
Vue.component('v-select', vSelect)


//sweet alert 1
import swal1 from 'sweetalert';
window.swal1 = swal1;



import swal from 'sweetalert2'
window.swal = swal;
const toast = swal.mixin({
    toast: true,
    position: 'top-end',
    showConfirmButton: false,
    timer: 3000
});
window.toast = toast;

/**
 * Next, we will create a fresh Vue ap
 *
 *
 * plication instance and attach it to
 * the page. Then, you may begin adding components to this application
 * or customize the JavaScript scaffolding to fit your unique needs.
 */

Vue.component('example-component', require('./components/ExampleComponent.vue'));
Vue.component('timetable-component', require('./components/TimetableComponent.vue'))   


/* filter active and inactive */

Vue.filter('activeInactive', function (value) {
    if(value==1){
        return 'Active'
    }else{
        return 'Inactive'
    }
  })

const app = new Vue({ 
    el: '#app',
    data:{

    },
    methods:{

    },
    mounted(){


    }





});

我认为我的app.js与表单请求的教程app.js完全相同。 另一件事是,在本教程中,他没有在任何地方使用axios import,但他使用得很流畅。但是如果没有导入,我将无法使用axios.then .... 他如何在不导入axios的情况下使用? 我如何才能最终与then.catch一起使用?

一个组件网:

loadSite() {
  axios
    .get("/api/site/list")
    .then(({ data }) => {
      console.log(data);
      this.siteList = data;
    })
    .catch(function(error) {
      console.log(error);
    }).finally(()=>{ 

    });
},

作为document,要使finally有效,您需要添加promise.prototype.finally

npm install axios promise.prototype.finally --save

然后

const axios = require('axios');
require('promise.prototype.finally').shim();

axios
  .get('http://www.example.com/user')
  .then((response) => {
    console.log(response.data);
    return response;
  })
  .finally(() => {
    console.log('this will always be called');
  });

我有同样的问题,只需添加此文件即可解决

<script src="https://polyfill.io/v3/polyfill.min.js?features=Promise.prototype.finally" defer></script>
