1、根据User-Agent判断
// Js获取User-Agent window.navigator.userAgent if(window.navigator.userAgent.match(/MicroMessenger/i) == "micromessenger") // Php获取User-Agent echo $_SERVER['HTTP_USER_AGENT']; if(strpos($_SERVER['HTTP_USER_AGENT'],'MicroMessenger')==true) // 微信内部打开获取到的User-Agent Mozilla/5.0 (Linux; U; Android 5.0.2; zh-cn; MI 2S Build/LRX22G) AppleWebKit/533.1 (KHTML, like Gecko)Version/4.0 MQQBrowser/5.4 TBS/025488 Mobile Safari/533.1 MicroMessenger/6.3.9.48_refecd3e.700 NetType/WIFI Language/zh_CN
2、Url地址判断
// 你网页正常的url是 https://forum.xxx.com/home.php?view=2015 // 使用微信打开会在url后面添加几个参数 https://forum.xxx.com/home.php?view=2015&from=timeline&isappinstalled=0
3、使用weixin-web-js判断是否是微信
