微信开放平台-小程序权限结婚-全网发布-返回api消息错误解决方案

首先有2个地址：

授权事件接收URL  处理接收  ticket，授权【authorized】，取消授权【unauthorized】等一些检查   返回success即可

公众号消息与事件接收URL：处理  返回api消息  的验证

1，获取微信服务器推送过来的消息，并且解密

function wxapp_decrypt_msg()
    {
        $encryptMsg =    file_get_contents('php://input');//微信推送过来的内容

        $xml_tree     =     new DOMDocument();
        $xml_tree->loadXML($encryptMsg);


        $ToUserName =     $xml_tree->getElementsByTagName('ToUserName');
        $ToUserName =     $ToUserName->item(0)->nodeValue;

        $array_e     =     $xml_tree->getElementsByTagName('Encrypt');//解密内容
        $encrypt     =     $array_e->item(0)->nodeValue;

        $timeStamp  =     empty($_GET['timestamp']) ? ""    : trim($_GET['timestamp']) ; 
        $nonce      =     empty($_GET['nonce']) ? ""    : trim($_GET['nonce']) ; 
        $msg_sign   =     empty($_GET['msg_signature']) ? ""    : trim($_GET['msg_signature']) ;
        $format     =     "<xml><ToUserName><![CDATA[toUser]]></ToUserName><Encrypt><![CDATA[%s]]></Encrypt></xml>";
        $from_xml     =     sprintf($format, $encrypt);
        $pc         =     new WXBizMsgCrypt(TOKEN, AESKEY, WXOPENAPPID);//开放平台的参数
        $errCode     =     $pc->decryptMsg($msg_sign, $timeStamp, $nonce, $from_xml, $msg);

        return array($errCode, $msg, $pc);//返回解密的内容
    }

 

2，获取 QUERY_AUTH_CODE 并且给客服发送消息

$errCode     =     wxapp_decrypt_msg();
        $msg         =    $errCode['1'];//解密的内容
        
        $xml_tree     =     new DOMDocument();
        $xml_tree->loadXML($msg);

        $Content     =    $xml_tree->getElementsByTagName('Content');
        $Content     =    $Content->item(0)->nodeValue;//微信发送的内容 包含 QUERY_AUTH_CODE:*****

        $openid     =    $xml_tree->getElementsByTagName('FromUserName');
        $openid     =    $openid->item(0)->nodeValue;//微信发送者的openid  给微信发送消息的时候 使用
        if(stripos($Content, 'QUERY_AUTH_CODE:') !== false)
        {
            echo '';
            $AuthCode     =    str_replace('QUERY_AUTH_CODE:', '', $Content);
            $wxapp         =    wxapp_get_info($AuthCode, 1);//通过authcode 获取微信授权测试小程序授权给开放平台的token
            $returnMsg     =    $AuthCode.'_from_api';//返回给微信的内容 $authCode.'_from_api' 后面_from_api 固定值
            $token         =    $wxapp['authorization_info']['authorizer_access_token'];
            $url         =    'https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token='.$token;
            $pushMsg     =    '{"touser":"'.$openid.'","msgtype":"text","text":{"content":"'.$returnMsg.'"}}';
            $pushJson     =    _public_http_curl_post($url, $pushMsg);
            exit;
        }
