下载好后代码如下:
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 = $GLOBALS["HTTP_RAW_POST_DATA"];
//extract post data
if (!emptyempty($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(!emptyempty( $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, SORT_STRING);
$tmpStr = implode( $tmpArr );
$tmpStr = sha1( $tmpStr );
if( $tmpStr == $signature ){
return true;
}else{
return false;
}
}
}
?>其中:TOKEN 修改为你自己想要的 然后在 开发者中心也要写一样的,在验证的过程中 $wechatObj->valid(); 这段代码不能去除这个是验证,验证成功后 我们就可以把 这段 $wechatObj->valid(); 这个注释掉了,然后使用 $wechatObj->responseMsg(); 来进行测试
注意:在开发的时候需要把 $wechatObj->valid(); 给注释掉,不然在手机测试的时候 会没有显示什么.
