npm install axios --save-dev 或者 cnpm install axios --save-dev
修改 Main.js
新增
var axios = require('axios')
axios.defaults.baseURL = 'http://localhost:8888/api'
//将API方法绑定到全局
Vue.prototype.$axios = axios
import Vue from 'vue'import VueRouter from 'vue-router'
import router from './router'
var axios = require('axios')
axios.defaults.baseURL = 'http://localhost:8888/api'
//将API方法绑定到全局
Vue.prototype.$axios = axios
// 导入 ElementUI
import ElementUI from 'element-ui'
import 'element-ui/lib/theme-chalk/index.css'
import App from './App'
// 安装路由
Vue.use(VueRouter);
// 安装 ElementUI
Vue.use(ElementUI);
new Vue({
el: '#app',
// 启用路由
router,
// 启用 ElementUI
render: h => h(App)
});
修改config/index.js
