HTTP_USER_AGENT of WeChat browser

On iPhone, return

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)

Under Android, return

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)

It is not difficult to find that the WeChat browser is MicroMessenger and has a version number. You can also determine whether the phone type is iPhone or Android

If you want to do hotlinking

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 judgment

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

After identifying the WeChat browser on the mobile phone, you can use WeChat’s sharing js script to process it. You can refer to WeChat’s official documentation. Here is a case to understand the general process and ideas

<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 = '<&#63;php echo base_url('/images/per.png'); &#63;>';
      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>
