PHP代码

if ( strpos($_SERVER['HTTP_USER_AGENT'], 'MicroMessenger') !== false ) { return ‘WeiXin’;}//判断是不是支付宝if (strpos($_SERVER['HTTP_USER_AGENT'], 'AlipayClient') !== false) { return "AliPay";}

JS判断

function WxOrAli(){ var ua = window.navigator.userAgent.toLowerCase(); //判断是不是微信 if ( ua.match(/MicroMessenger/i) == 'micromessenger' ) { return "WeiXIN"; } //判断是不是支付宝 if (ua.match(/AlipayClient/i) == 'alipayclient') { return "Alipay"; } //哪个都不是 return "false";}
