VUE系列三：实现跨域请求(fetch/axios/proxytable)

// 1. 模板：html结构 有且只有一个根标签
<template>
<div id="app">
<!-- 使用路由实现跳转 注意：to里面写的是路由的名字 -->
<ul>
<li><router-link to="/">home</router-link></li>
<li><router-link to="/Users">Users</router-link></li>
</ul>
<!-- 进入首页默认加载的路由 -->
<router-view></router-view>
</div>
</template>//2. 行为：处理逻辑
<script>export default {
name: 'App',//组件App.vue的名字
data () {
return { }
},
//实现跨域请求
created(){
//fetch实现跨域请求
fetch("/apis/test/testToken.php",{
method:"POST",
headers:{
token:"f4c902c9ae5a2a9d8f84868ad064e706" },
body:JSON.stringify({username:"lgs",password:"123"})
}).then(result=>{
// console.log(result)
//解析数据
return result.json()
}).then(data =>{
//打印数据
console.log(data);
}) }
