php企业微信通讯录同步设置接收事件服务器

第一步登陆企业微信pc端管理后台设置好信息,先不要点击保存,会提示失败

随后根据填写的URL编写接口,接口代码如下:

		//就是第一步图中的token
        $token = 'xxx';
        //就是第一步图中的EncodingAESKey
        $encodingAESKey = 'xxx';
        //企业微信corpid,前往我的企业->企业ID 内查看
        $receiveid= 'xxx';
        
        $signature = $_GET('msg_signature');

        $timestamp = $_GET('timestamp');

        $echostr = $_GET('echostr');

        $nonce = $_GET('nonce');



        $key = base64_decode($encodingAESKey . '=');

        $iv = substr($key, 0, 16);

        $array = array($echostr, $token, $timestamp, $nonce);

        sort($array, SORT_STRING);

        $str = implode($array);

        $decryptSignature = sha1($str);

        if ($signature != $decryptSignature){

            return false;

        }

        $decrypted = openssl_decrypt($echostr, 'AES-256-CBC', $key, OPENSSL_ZERO_PADDING,$iv);

        $pad = ord(substr($decrypted, -1));

        $result = substr($decrypted, 0, (strlen($decrypted) - $pad));

        //拆分

        $content = substr($result, 16, strlen($result));

        $len_list = unpack('N', substr($content, 0, 4));

        $xml_len = $len_list[1];

        $xml_content = substr($content, 4, $xml_len);
        
	 	$from_receiveId = substr($content, $xml_len+ 4);
		if($from_receiveId  != $receiveid){
				return false;
		}
        //返回验证内容

        echo $xml_content;

第三步返回pc端界面点击保存,设置回调服务器成功
