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.
