微信支付涉及了很多场景,例如web端时我们调用的是二维码支付、若到了微信浏览器中我们则可以直接调取微信内部支付模块。
最近遇到一个场景,当用户在PC端打开微信客户端,并打开对应的H5页面,进入支付页面,此时若只判断MicroMessenger则会发现,用户在当前页面无法唤起微信内部支付模块。必须在移动端才能正常使用。
所以当遇到该类情况,建议通过下列方式判断。
/** * //判断是否手机设备 * @return boolean */ function isMobileRequest(){ $_SERVER['ALL_HTTP'] = isset($_SERVER['ALL_HTTP']) ? $_SERVER['ALL_HTTP'] : ''; $mobile_browser = '0'; if(preg_match('/(up.browser|up.link|mmp|symbian|smartphone|midp|wap|phone|iphone|ipad|ipod|android|xoom)/i', strtolower($_SERVER['HTTP_USER_AGENT']))) $mobile_browser++; if((isset($_SERVER['HTTP_ACCEPT'])) and (strpos(strtolower($_SERVER['HTTP_ACCEPT']),'application/vnd.wap.xhtml+xml') !== false)) $mobile_browser++; if(isset($_SERVER['HTTP_X_WAP_PROFILE'])) $mobile_browser++; if(isset($_SERVER['HTTP_PROFILE'])) $mobile_browser++; $mobile_ua = strtolower(substr($_SERVER['HTTP_USER_AGENT'],0,4)); $mobile_agents = array( 'w3c ','acs-','alav','alca','amoi','audi','avan','benq','bird','blac', 'blaz','brew','cell','cldc','cmd-','dang','doco','eric','hipt','inno', 'ipaq','java','jigs','kddi','keji','leno','lg-c','lg-d','lg-g','lge-', 'maui','maxo','midp','mits','mmef','mobi','mot-','moto','mwbp','nec-', 'newt','noki','oper','palm','pana','pant','phil','play','port','prox', 'qwap','sage','sams','sany','sch-','sec-','send','seri','sgh-','shar', 'sie-','siem','smal','smar','sony','sph-','symb','t-mo','teli','tim-', 'tosh','tsm-','upg1','upsi','vk-v','voda','wap-','wapa','wapi','wapp', 'wapr','webc','winw','winw','xda','xda-' ); if(in_array($mobile_ua, $mobile_agents)) $mobile_browser++; if(strpos(strtolower($_SERVER['ALL_HTTP']), 'operamini') !== false) $mobile_browser++; // Pre-final check to reset everything if the user is on Windows if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']), 'windows') !== false) $mobile_browser=0; // But WP7 is also Windows, with a slightly different characteristic if(strpos(strtolower($_SERVER['HTTP_USER_AGENT']), 'windows phone') !== false) $mobile_browser++; if($mobile_browser>0) return true; else return false; } /** * //判断是否微信浏览器 * @return boolean */ function isWeChat{ $user_agent = $_SERVER['HTTP_USER_AGENT']; if(strpos($user_agent, 'MicroMessenger') !== false){ return true; } return false; }
上列两个方法,isMobileRequest(用于判断是否移动端);isWeChat(用于判断是否微信浏览器)。
将两个方法结合使用,可以避免在PC端的微信浏览器中因判断不齐而导致无法支付。
