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>

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.

Dependency injection (DI) significantly improves the testability of PHP code by explicitly transitive dependencies. 1) DI decoupling classes and specific implementations make testing and maintenance more flexible. 2) Among the three types, the constructor injects explicit expression dependencies to keep the state consistent. 3) Use DI containers to manage complex dependencies to improve code quality and development efficiency.
