HTTP_USER_AGENT of the browser

Under the 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)

In Android

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 browser is MicroMessenger and has a version number. You can also determine whether the mobile phone type is iPhone or Android.

If you want to perform leeching

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 "please visit this website. ";}
Js judgment

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

After the browser is determined on the mobile phone end, you can use the share js script to process it. For details, refer to the official document. Here is a case study to learn about the general process and ideas.
