微信公眾平台開發，外部調用介面傳參，然後把參數以圖文形式回複

公眾平台開發，外部調用介面以URL形式傳參，然後寫使用者關注後以圖文形式回複，圖片的url就是傳過來的參數
。但是我關注後沒有獲得參數。

http://xxx.duapp.com/wechat/api.php?id=http://203.111.111.111:1212/img/635932895447623934.png  代碼如下：

• wechat php test
*/
//define your token

$imgurl = $_GET['id'];

define("TOKEN", "weixin");
$wechatObj = new wechatCallbackapiTest();
$wechatObj->responseMsg();

1. wechatCallbackapiTest
{

    public function valid() { $echoStr = $_GET["echostr"]; //valid signature , option if($this->checkSignature()){ echo $echoStr; exit; } } public function responseMsg() { //get post data, May be due to the different environments $postStr = $GLOBALS["HTTP_RAW_POST_DATA"]; //extract post data if (!empty($postStr)){ $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA); $fromUsername = $postObj->FromUserName; $toUsername = $postObj->ToUserName; $keyword = trim($postObj->Content); $time = time(); $imgurl = $_GET['id']; $textTpl = " %s %s %s %s %s 0 "; $ev = $postObj->Event; if ($ev == "subscribe") { $PicUrl = $imgurl; $Url = $imgurl; $textTpl = " %s %s %s news 1  <![CDATA[歡迎加入貝海科技]]> 貝海科技魔鏡 {$PicUrl} {$Url}     "; 

    $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time); echo $resultStr; } if(!empty( $keyword )) { $msgType = "text"; switch ($keyword) { case "1"; $contentStr = "公司簡介!"; break; case "2"; $contentStr = "最新優惠!"; break; case "3"; $contentStr = "圖片連結如下:".$_GET['id']; break; default; $contentStr = "歡迎光臨!"; } $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr); echo $resultStr; }else{ echo "Input something..."; } }else { echo ""; exit; } } private function checkSignature() { $signature = $_GET["signature"]; $timestamp = $_GET["timestamp"]; $nonce = $_GET["nonce"]; $token = TOKEN; $tmpArr = array($token, $timestamp, $nonce); sort($tmpArr); $tmpStr = implode( $tmpArr ); $tmpStr = sha1( $tmpStr ); if( $tmpStr == $signature ){ return true; }else{ return false; } }

   }
