初识php——微信消息处理

 <?php

 $test = new weixin();
 $test->Message();

 class weixin{
     public function Message(){
         $postStr = $GLOBALS["HTTP_RAW_POST_DATA"];
         if (!empty($postStr)){
             $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
             $fromUsername = $postObj->FromUserName;
             $toUsername = $postObj->ToUserName;
             $createTime = trim($postObj->CreateTime);
             $createtime = date('Y/m/d H:i:s', $createTime);
             $msgType = trim($postObj->MsgType);
             $result = "FromUserName(来自)：{$fromUsername}\r\n"
             ."ToUserName(发送至)：{$toUsername}\r\n"
             ."CreateTime(时间)：{$createtime}\r\n"
             ."MsgType(消息类型)：{$msgType}\r\n";
             switch ($msgType){
                 case "event":
                     $result = $result.$this->receiveEvent($postObj);
                     break;
                 case "text":
                     $result = $result.$this->receiveText($postObj);

             }
             echo "原始消息\r\n";
             echo $postStr ;
             echo "\r\n\r\n解析结果\r\n";
             echo $result;

         else{

     private function receiveEvent($postObj){
         $event =  $postObj->Event;
         $eventKey = $postObj->EventKey;
         $result = "Event(事件)：{$event}\r\n"
         ."EventKey(事件值)：{$eventKey}";
         return $result;
     }

     private function receiveText($postObj){
         $keyword = trim($postObj->Content);
         $msgId = $postObj->MsgId;
         $result = "Content(文本内容)：{$keyword}\r\n"
         ."MsgId(文本消息标识号)：{$msgId}";
         return $result;
     }
