axios 實現 get 請求，這是一段很簡單但很實用的代碼。
console.log('i have a dream !')
let banner = Math.floor(Math.random() * 1000)
let api = `http://mock.xunsu.online/mock/index/get/arg/` + banner
let msg = ''
axios.get(api).then((response) => {
if (response.data.code == 0) {
console.log(response.data.data)
msg = "歡迎光臨！"
} else {
msg = "網絡異常！"
}
alert(msg)
})
接口說明：
http://mock.xunsu.online/mock/index/get/arg/xxx
接口是在線的，代碼可以不用修改直接執行。
再分享一個在線的調試示例，可以在瀏覽器開發者模式觀察請求。

在使用前記得引入 axios 庫。
比如可以用這個庫：
http://mock.xunsu.online/lib/axios/axios.min.js
引入只要在請求代碼之前就可以。比如：
<script src="/lib/axios/axios.min.js"></script>
<script src="/d/demo_index.js?v=0.0.1.200426"></script>
這裏，demo_index.js是我們的業務代碼，只要在這之前引入 axios 就可以。
下面貼一下網頁完整的html代碼，供參考
