根据这个 https://developers.weixin.qq.com/doc/oplatform/Mobile_App/WeChat_H5_Launch_APP.html
我已成功配置 wx.config，并且H5上成功显示 “<wx-open-launch-app>" 按钮，点击按钮可以打开App，代码如下：
<wx-open-launch-app
id="launch-btn"
appid="wx4fc78bcc171981ff"
extinfo="请问H5页面上的参数怎么传给Universal link，然后再打开指定的页面？"
>
<script type="text/wxtag-template">
<style>.btn {padding: 22px; background-color:#C62849; font-size:25px; border-style: solid; color:#fff}</style>
<span class="btn">点击进入App</span>
</script>
</wx-open-launch-app>
extinfo 填写什么内容？怎么把内容传给UniversalLink，然后打开指定的页面？
Xcode的 AppDelegate.m file怎修改来接受extinfo的内容，然后传给Universal Link？
谢谢!
想问一下。你通过这套代码能拿到extinfo的值么。。我都进不到onreq里面。可否留个联系方式 想请教一下
文档上说格式自定义了，传的时候传字符串，打开什么页面app里面根据传参判断咯
