微信扫二维码调用外部浏览器打开指定页面

需求分析

将打包好的apk/ios文件部署到服务器，把下载页面的URL通过二维码编辑器或根据URL代码生成一个二维码，然后通过二维码进行微信推广已经成为很多用户惯用的方式。但微信会对含apk/ios文件的链接进行了屏蔽，所以导致微信扫码打不开下载链接。理想的状态是安卓自动下载，苹果点击左上角按钮前往Safari下载。那么究竟该如何处理才能达到理想的结果呢？

我们知道 js 可以通过 window.navigator.userAgent 来获取浏览器的相关信息，比如：Mozilla/5.0 (Windows NT 5.1) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/33.0.1750.154 Safari/537.36，那么我们也可以通过该方法来获取微信内置浏览器的相关信息：Mozilla/5.0 (iPhone; CPU iPhone OS 7_1_1 like Mac OS X) AppleWebKit/537.51.2 (KHTML, like Gecko) Mobile/11d201 MicroMessenger/5.3。根据关键字 MicroMessenger 来判断是否是微信内置的浏览器。从而实现安卓自动下载或跳转到浏览器打开下载链接，苹果会提示点击右上角的按钮前往Safari下载。
