本篇文章主要讲述的是PHP实现微信公众号图文消息回复与access_token,具有一定的参考价值,感兴趣的朋友可以了解一下。
//代码如下 <?php class IndexAction extends Action { public function __construct(){ } public function index(){ //获得参数 signature nonce token timestamp echostr $nonce = $_GET['nonce']; $token = 'imooc'; $timestamp = $_GET['timestamp']; $echostr = $_GET['echostr']; $signature = $_GET['signature']; //形成数组,然后按字典序排序 $array = array(); $array = array($nonce, $timestamp, $token); sort($array); //拼接成字符串,sha1加密 ,然后与signature进行校验 $str = sha1( implode( $array ) ); if( $str == $signature && $echostr ){ //第一次接入weixin api接口的时候 echo $echostr; exit; }else{ $this->reponseMsg(); } } // 接收事件推送并回复 public function reponseMsg(){ //1.获取到微信推送过来post数据(xml格式) $postArr = $GLOBALS['HTTP_RAW_POST_DATA']; //2.处理消息类型,并设置回复类型和内容 /*<xml> <ToUserName><![CDATA[toUser]]></ToUserName> <FromUserName><![CDATA[FromUser]]></FromUserName> <CreateTime>123456789</CreateTime> <MsgType><![CDATA[event]]></MsgType> <Event><![CDATA[subscribe]]></Event> </xml>*/ $postObj = simplexml_load_string( $postArr );
