How to reference vue in .js file

Methods to reference vue in js files: 1. Define a variable context to receive vue, and then execute the initContext method exported by http.js; 2. Create a main.js export vue instance, and then use it in the Just introduce the example into js.

Refer to the vue instance in the js file

The first method:

1. First, in http.js: define a variable context for Receive vue, then set the parameter passed in to the initVue method to be vue, and export this method.

import axios from 'axios'
const TIME_OUT_MS = 60 * 1000 // 默认请求超时时间
let context = null // 定义一个变量，用来代替this（vue）
function handleResults (response) {
    context.$router.push('/login') 
    return result
}
export default {
  // 写一个此文件引入vue的方法，然后export导出去
    initContext (vue) {
        context = vue
    },
    post (url, data, response, exception) {
      
    },

2. Then in main.js: execute the initContext method exported by http.js

var vue = new Vue({
    el: '#app',
    router,
    components: {App},
    template: ''
})
Vue.prototype.http = http
//挂载http的时候执行引入vue的方法
Vue.prototype.http.initContext(vue) // 传入vue实例
