单HTML文件集成Vue2+axios的使用
1、下载vue2.js和axios.js到本地
2、建一个HTML文件，内容如下：
<html>
<head><meta charset="UTF-8"><script src="./js/vue2.js"></script><script src="./js/axios.js"></script>
</head><body><div id="app"><p>vue2+axios</p><div>{{ info }}</div><button @click="getInfo">getInfo</button></div><script>new Vue({el: "#app",data:{info:''},methods: {getInfo() {that = thisaxios.get("https://127.0 0.1/getInfo").then(response => {console.log(response.data)that.info=response.data}).catch( error => {console.log(error)});}}})</script>
</body></html>
