我已阅读有关我的问题
VUE JS 2 + WEBPACK Cannot read property 'get' of undefined VUE RESOURCE
但我的系统没有读过Vue var：（
我有一个vue组件调用app.vue，我需要使用vue-resource从我的帖子中获取数据。但错误很多次是：
TypeError: Cannot read property 'post' of undefined
at VueComponent.loadingProcess
你有想法解决它吗？
我的app.vue
<script>
var Vue = require('vue');
//Vue.use(require('vue-resource'));
//Vue.use();
export default {
data () {
return {
msg: 'Hello from vue-loader! nice!',
user: {}
}
},
mounted: function () {
this.loadingProcess();
},
methods: {
loadingProcess: function () {
var urlPost;
var answQSend = {...};
var that = this;
var jsonSend = {
"form_data": answQSend,
"prod_id": 3
};
Vue.$http.post(urlPost, jsonSend, {
"headers": {
"content-type": "application/json"
}
})
.then(function(response) {
})
...
提前致谢！

在我的main.js中，我改变了这一行

的
var VueResource = require('vue-resource');
并使用
import VueResource from "vue-resource"
然后，在我的app vue组件中，我改变了
Vue.use(VueResource);
有关
Vue.http.post
这样我们就修正了错误！

您使用的是导出默认脚本，因此您的this关键字无权访问Vue实例原始模块，而是访问导入的对象组件。最有可能的情况是，对于require，vue-resource仅对原始模块可用，因此使用来自“vue-resource”的import VueResource，使用es6语法，vue-resource库将被提升为内部模块，之后在Vue实例旁边的浏览器上进行评估和缓存。在某些情况下，人们不使用箭头功能并超出范围。 另一种方法是使用Vue实例本身而不是导出默认对象。看看http://voidcanvas.com/import-vs-require/你可能会比我做得更多。
