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>
