扫二维码自动识别安卓苹果端

作者: SYOL | 来源:发表于2016-03-19 00:42 被阅读957次

    相信很多朋友都遇到过这样的一种情况吧，老板要求一个二维码集成2个链接（安卓和苹果），手机一扫就可以自动识别安卓机和苹果机了。但是怎么实现又犯难了吧，百度了很多都找不到合适的答案，我特此在这写那么一篇关于这要求的文章，希望可以帮助到你。
    思路：
    二维码就无非是一个URL，所以根据这个思路是需要一个页面，承载这个URL，在这个页面中进行处理识别安卓机和苹果机，但是微信的安全性做了限制，一般都会屏蔽来源不是腾讯的 APK,所以需要在用户扫二维码之后给用户一个提示，让他去跳转。这就和HTML有关系了。
    步骤：
    新建一个网页（HTML）
