Token:这个值可以随便写。
打开文件wx_sample.php,修改下面的内容
define("TOKEN", "weixin"); //修改成自己填写的token
填写之后,就可以提交了!
验证成功之后,我们可以写一个小例子测试一下,如下代码:
responseMsg();class 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(); $textTpl = ""; if(!empty($keyword)) { $msgType = "text"; $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; } }}?> %s 0
最简单的回复消息完成了!
