在微信公众号里访问我的H5页面，js获取到的：【Mozilla/5.0 (Linux; Android 9; CLT-AL00 Build/HUAWEICLT-AL00; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/66.0.3359.126 MQQBrowser/6.2 TBS/045131 Mobile Safari/537.36 MMWEBID/1339 MicroMessenger/7.0.13.1640(0'000D72) Process/tools NetType/WIFI Language/zh_CN ABI/arm64 WeChat/arm64】

中间我们没有做user-agent处理，怎么到我们服务端以后就只剩【Mozilla/5.0 (Linux; Android 9; CLT-AL00 Build/HUAWEICLT-AL00; wv) AppleWebKit/537.36 (KHTML, like Gecko) Version/4.0 Chrome/66.0.3359.126 MQQBrowser/6.2 TBS/045131 Mobile Safari/537.36】这一部分了，MicroMessenger丢失无法判断微信了
