soap服务的代理服务

公司项目需要通过soap请求ERP软件获得返回数据,但是目前存在一个问题,当请求ERP次数过多的时候,ERP服务器会拒绝访问,以至于后续业务进行不下去.
联系过ERP机房的人无疾而终.
后来发现,通过不同的端口又可以访问ERP服务器.
国哥做了一个ERP访问代理服务,当第一方案不通的时候,采用第二方案.

先来看ERP请求的方法

    public function requestGetRecordSet($aCmdText)
    {
        //soap初始化
        $this->connect();
        //加密salt
        $aCheckCode = $this->cryption->encrypt($this->checkSalt . $this->cryption->checkCode($aCmdText));
        //开启代理走代理,没开启走之前
        if ($this->proxy->isProxy()) {
            //魔术方法将方法名和参数传入代理服务
            $rawData = $this->proxy->getRecordSet($aCmdText, $aCheckCode);
        } else {
            $rawData = $this->client->getRecordSet($aCmdText, $aCheckCode);
            if (empty($rawData)) {
                throw new SoapException(SoapException::E_401);
            }
        }
        return $this->formatRecordSetData($this->formatXMLData($rawData));
    }

上面提到的代理服务是怎么接收方法名和参数的呢?
其实代理客户端除了初始化的基本逻辑外什么方法都没有,都是通过__call将外部服务的方法和参数存储起来

class SoapProxy
{

    protected $proxyState = false;

    protected $erpConf;

    protected $auth = 'yRsIx480yhptRVR4VKaXFJgNcjMfxYZ0';
    
    //代理要访问的服务器地址
    protected $proxyUrl = 'https://boshi.unionglasses.com:8081/Soap/';

    public function setErpConf($erpConf)
    {
        if (isset($erpConf['proxy'])) {
            if (is_string($erpConf['proxy'])) {
                if (stripos($erpConf['proxy'], 'http') === 0) {
                    $this->enableProxy();
                    $this->proxyUrl = $erpConf['proxy'];
                }
            } elseif (is_bool($erpConf['proxy'])) {
                $this->enableProxy();
            }
        }
        $this->erpConf = [
            'domain' => $erpConf['domain']
        ];
    }

    public function enableProxy($enable = true)
    {
        $this->proxyState = $enable;
    }

    public function isProxy()
    {
        return $this->proxyState;
    }

    //魔术方法获得方法名和参数
    public function __call($method, $args)
    {
        $postData = [];
        $postData['soapInf'] = $method;
        $postData['soapParam'] = $args;
        $postData['access_token'] = $this->auth;
        $postData['erpConf'] = $this->erpConf;
        return $this->request($postData);
    }

    //curl请求带入方法名和参数,获得返回值后,返回给外部服务
    public function request($postData)
    {
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $this->proxyUrl);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);
        curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
        curl_setopt($ch, CURLOPT_HEADER, FALSE);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
        curl_setopt($ch, CURLOPT_POST, 1);
        curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($postData));
        $res = curl_exec($ch);
        curl_close($ch);
        $rawData = '';
        if (! empty($res)) {
            $res = json_decode($res, true);
            if (isset($res['errcode']) && $res['errcode'] === 0 && isset($res['rawData'])) {
                $rawData = $res['rawData'];
                if (empty($rawData)) {
                    throw new SoapException(SoapException::E_401);
                }
            }
        }
        if (empty($rawData)) {
            throw new SoapException(SoapException::E_402);
        }
        return $rawData;
    }
}
