PHP JS判断浏览器，微信浏览器

微信内置浏览器的 User Agent

如何判断微信内置浏览器，首先需要获取微信内置浏览器的User Agent，经过在 iPhone 上微信的浏览器的检测，它的 User Agent 是：

Mozilla/5.0 (iPhone; CPU iPhone OS 6_1_3 like Mac OS X) AppleWebKit/536.26 (KHTML, like Gecko) Mobile/10B329 MicroMessenger/5.0.1

所以通过识别 MicroMessenger 这个关键字来确定是否微信内置的浏览器了。

js判断

function is_weixin(){
    var ua = navigator.userAgent.toLowerCase();
    if(ua.match(/MicroMessenger/i)=="micromessenger") {
        return true;
     } else {
        return false;
    }
}

PHP判断

<?php

 $agent =  $_SERVER[‘HTTP_USER_AGENT‘]    

if( strtopos( $agent, ‘MicroMessenger‘) {

  echo ‘微信浏览器‘;

}else if( strpos($userAgent,"iPhone") || strpos($userAgent,"iPad") || strpos($userAgent,"iPod") || strpos($userAgent,"iOS") ) {

echo ‘苹果设备‘;

 } else if( strpos($userAgent,"Android") ) {
echo ‘android 设备‘;

}

?>

当在手机端判断到微信浏览器之后，可以使用微信的分享js脚本对其进行处理,大家可以参考微信的官方文档，这里提供一个案例，了解下大概流程和思路

<script type="text/javascript" src="/jslib/wx_share.js"></script>
        <script>
            //分享链接时给其重写分享的标题、缩略图、链接、简介等
            var imgUrl = ‘<?php echo base_url(‘/images/per.png‘); ?>‘;
            var lineLink = ‘http://www.baidu.com/‘;
            var shareTitle = ‘我来给你送钱了‘;
            var descContent = ‘折射率，你知道是啥？‘;
            var timeline_title = ‘timeline_title‘;
            var appid = ‘‘;
        </script>
        <script>
            function onBridgeReady() {
                WeixinJSBridge.call(‘showOptionMenu‘);
            }
        </script>
        <script>
            if (typeof WeixinJSBridge == "undefined") {
                if (document.addEventListener) {
                    document.addEventListener(‘WeixinJSBridgeReady‘, onBridgeReady, false);
                } else if (document.attachEvent) {
                    document.attachEvent(‘WeixinJSBridgeReady‘, onBridgeReady);
                    document.attachEvent(‘onWeixinJSBridgeReady‘, onBridgeReady);
                }
            } else {
                onBridgeReady();
            }
        </script>
</head>
