php 微信开发平台开发小测验

<?php /*** wechat php test*///define your tokendefine("TOKEN", "weixin");//此时你的微信公众平台的token即为weixin$wechatObj = new wechatCallbackapiTest();$wechatObj->valid();class wechatCallbackapiTest{public function valid(){$echoStr = $_GET["echostr"];//valid signature , optionif($this->checkSignature()){echo $echoStr;exit;}}public function responseMsg(){//get post data, May be due to the different environments$postStr = $GLOBALS["HTTP_RAW_POST_DATA"];//extract post dataif (!empty($postStr)){$postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);$fromUsername = $postObj->FromUserName;$toUsername = $postObj->ToUserName;$keyword = trim($postObj->Content);$time = time();$textTpl = "<xml><tousername></tousername><fromusername></fromusername><createtime>%s</createtime><msgtype></msgtype><content></content><funcflag>0</funcflag></xml>";if(!empty( $keyword )){$msgType = "text"; （PS：^_^不错的php学习交流群：276167802，验证：csl，有兴趣的话可以加入进来一起讨论）$contentStr = "Welcome to wechat world!";$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;}}}?>

创建新版本成功后如图所示，此时应用创建成功：
