vue3引入axios

在使用vue add axios后，项目中会出现一个plugins文件夹，里面有一个axios.js
在main.js中挂载axios到全局

import { createApp } from 'vue'
import App from './App.vue'
import router from './router'
import store from './store'
import axios from "axios";

const app = createApp(App)
app.config.globalProperties.$axios = axios
app.use(store)
app.use(router)
app.mount('#app')

使用时：

created() {
      this.$axios.get('http://localhost:8080/xxx')
      .then(res => {
        console.log(res);
      });
    }
