上传到服务器，微信验证(wx_sample.php)

说明

第一次验证，调用valid方法，之后就可以切换成responseMsg方法进行自动回复了

判断事件类型：text为发送文本事件，event为触发事件

<?php//定义你的验证tokendefine("TOKEN", "weixin");$wechatObj = new wechatCallbackapiTest();//$wechatObj->valid();$wechatObj->responseMsg();class wechatCallbackapiTest { public function valid() { $echoStr = $_GET["echostr"]; if($this->checkSignature()){ echo $echoStr; exit; } } private function checkSignature() { if (!defined("TOKEN")) { throw new Exception(‘TOKEN is not defined!‘); } $signature = $_GET["signature"]; $timestamp = $_GET["timestamp"]; $nonce = $_GET["nonce"]; $token = TOKEN; $tmpArr = array($token, $timestamp, $nonce); // use SORT_STRING rule sort($tmpArr, SORT_STRING); $tmpStr = implode( $tmpArr ); $tmpStr = sha1( $tmpStr ); if( $tmpStr == $signature ){ return true; }else{ return false; } } public function responseMsg() { $postStr = $GLOBALS["HTTP_RAW_POST_DATA"]; if (!empty($postStr)){ $postObj = simplexml_load_string($postStr, ‘SimpleXMLElement‘, LIBXML_NOCDATA); $MsgType = trim($postObj->MsgType); //判断是发送文本事件还是触发事件 switch ($MsgType) { case "text": $resultStr = $this->receiveText($postObj); break; case "event": $resultStr = $this->receiveEvent($postObj); break; default: $resultStr = ""; break; } echo $resultStr; }else { echo ""; exit; } } private function receiveText($object) { $funcFlag = 0; $key=$object->Content; if($key==‘房客‘){ $contentStr[] = array("Title" =>"房客指南", "Description" =>"查看恋家房客指南", "PicUrl" =>"http://www.test.com/img/1.jpg", "Url" =>"http://www.test.com/tg.php"); $resultStr = $this->transmitNews($object, $contentStr); }else{ $key=intval($key); if($key){ $contentStr[] = array("Title" =>‘推送框标题‘, "Description" =>‘推送框说明‘, "PicUrl" =>‘http://www.test.com/img/‘.$key.‘.jpg‘,//显示图片 "Url" =>"http://www.test.com/room/$key");//点击后跳转页面 $resultStr = $this->transmitNews($object, $contentStr); }else{ //返回文本 $contentStr = "请输入正确内容（数字）"; $resultStr = $this->transmitText($object, $contentStr, $funcFlag); } } return $resultStr; } private function receiveEvent($object) { $contentStr = ""; switch ($object->Event) { //关注微信事件 case "subscribe": $contentStr = "欢迎关注恋家网"; //取消关注事件 case "unsubscribe": break; //点击事件 case "CLICK": switch ($object->EventKey) { //如果点击按钮接收关键词为mtr case "mtr": $contentStr[] = array("Title" =>"神秘房客报名", "Description" =>"恋家神秘房客报名享大礼", "PicUrl" =>"http://www.test.com/img/mtr.jpg", "Url" =>"http://www.test.com/mtr.php"); break; //如果点击按钮接收关键词为lg case "lg": $contentStr[] = array("Title" =>"房东指南", "Description" =>"查看恋家房东指南", "PicUrl" =>"http://www.test.com/img/lg.jpg", "Url" =>"http://www.test.com/lg.php"); break; //如果点击按钮接收关键词为tg case "tg": $contentStr[] = array("Title" =>"房客指南", "Description" =>"查看恋家房客指南", "PicUrl" =>"http://www.test.com/img/tg.jpg", "Url" =>"http://www.test.com/tg.php"); break; //其他点击事件 default: $contentStr[] = array("Title" =>"默认菜单回复", "Description" =>"您正在使用的是恋家网的自定义菜单测试接口", "PicUrl" =>"http://www.test.com/img/default.jpg", "Url" =>"http://www.test.com/img/default.php"); break; } break; //其它事件 default: break; } if (is_array($contentStr)){ $resultStr = $this->transmitNews($object, $contentStr); }else{ $resultStr = $this->transmitText($object, $contentStr); } return $resultStr; } private function transmitText($object, $content, $funcFlag = 0) { $textTpl = "<xml> <ToUserName><![CDATA[%s]]></ToUserName> <FromUserName><![CDATA[%s]]></FromUserName> <CreateTime>%s</CreateTime> <MsgType><![CDATA[text]]></MsgType> <Content><![CDATA[%s]]></Content> <FuncFlag>%d</FuncFlag> </xml>"; $resultStr = sprintf($textTpl, $object->FromUserName, $object->ToUserName, time(), $content, $funcFlag); return $resultStr; } private function transmitNews($object, $arr_item, $funcFlag = 0) { //首条标题28字，其他标题39字 if(!is_array($arr_item)) return; $itemTpl = "<item> <Title><![CDATA[%s]]></Title> <Description><![CDATA[%s]]></Description> <PicUrl><![CDATA[%s]]></PicUrl> <Url><![CDATA[%s]]></Url> </item>"; $item_str = ""; foreach ($arr_item as $item) $item_str .= sprintf($itemTpl, $item[‘Title‘], $item[‘Description‘], $item[‘PicUrl‘], $item[‘Url‘]); $newsTpl = "<xml> <ToUserName><![CDATA[%s]]></ToUserName> <FromUserName><![CDATA[%s]]></FromUserName> <CreateTime>%s</CreateTime> <MsgType><![CDATA[news]]></MsgType> <Content><![CDATA[]]></Content> <ArticleCount>%s</ArticleCount><Articles> $item_str</Articles> <FuncFlag>%s</FuncFlag> </xml>"; $resultStr = sprintf($newsTpl, $object->FromUserName, $object->ToUserName, time(), count($arr_item), $funcFlag); return $resultStr; }}?>
