最近在做App二维码下载的功能，需要在后端判断扫描来自PC，Android手机还是苹果手机，所以将常见的浏览器User Agent记录下来。

之所以把微信的内嵌浏览器User-Agent单列出来，是因为使用微信扫码会中止跳转，需要使用“在浏览器打开”才能完成接下来的动作。

至于判断本身逻辑就比较简单了，如下：

const weixinTip = '';
app.get('/getappaddr', (req, res) => {
  let userAgent = req.headers['user-agent'];
  if (/MQQBrowser/g.test(userAgent) || /MicroMessenger/g.test(userAgent)) { // open page with weixin
    res.send(weixinTip);
  } else if (/Android/g.test(userAgent)) { // Android browser
    res.redirect('http://xxxxx/xxxx.apk');
  } else if (/Mac OS/g.test(userAgent)) { // iOS browser
    res.redirect('https://itunes.apple.com/cn/app/apple-store/idxxxxxx?mt=8');
  } else { // others (eg. pc) not support
    res.send('Request not support');
  }
});
