微信浏览器的HTTP_USER_AGENT
在iPhone下,返回
Mozilla/5.0 (iPhone; CPU iPhone OS 5_1 like Mac OS X) AppleWebKit/534.46 (KHTML, like Gecko) Mobile/9B176 MicroMessenger/4.3.2)
在Android下,返回
Mozilla/5.0 (Linux; U; Android 2.3.6; zh-cn; GT-S5660 Build/GINGERBREAD) AppleWebKit/533.1 (KHTML, like Gecko) Version/4.0 Mobile Safari/533.1 MicroMessenger/4.5.255)
不难发现微信浏览器为 MicroMessenger ,并且有版本号,也可以判断手机类型为iPhone还是Android
如果要做盗链
if(strpos($_SERVER["HTTP_USER_AGENT"],"MicroMessenger"))
echo "Welcome to wechat word";
else
echo "http/1.1 401 Unauthorized";
public function is_weixin(){
if ( strpos($_SERVER['HTTP_USER_AGENT'], 'MicroMessenger') !== false ) {
return true;
}
return false;
}
if($this->is_weixin()){
}else{
echo "请使用微信访问本网址。";
}
js判断
function is_weixin(){
var ua = navigator.userAgent.toLowerCase();
if(ua.match(/MicroMessenger/i)=="micromessenger") {
return true;
} else {
return false;
}
}
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>
