Essence: Use the official document and call

$wechatObj->valid();

instead of, after commenting, call:

$wechatObj->responseMsg(); Regarding the solution to the "Your service failed to respond correctly to Token verification" error on the WeChat public platform valid(); 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 = " %s 0 "; 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; } } } ?> The above is an example of the interface file officially provided by Tencent. Solving the problem is actually very simple. It seems that the WeChat document is not written (or I can't find it==):
Use when verifying the token: $wechatObj->valid(); When you need to reply to user messages in the formal production environment, use: $wechatObj->responseMsg();
Problem solved.

The above introduces the solution to the "Your service failed to respond correctly to Token verification" error on the WeChat public platform, including the relevant content. I hope it will be helpful to friends who are interested in PHP tutorials.
