PHP SOAP数组错误

我试图使用一个方法，但它返回登录失败的消息，但在SOAPUI中它工作正常

我想错误在我发送的数组中

与XML相比，这是我的数组吗

XML:

返回：

Fatal error:  Uncaught SoapFault exception: [s:Client] Login Failed. in /var/www/html/Consume.php:85

函数类Cosume：

public function Product(){

    $client = new SoapClient( $this->wsdl_url, array( "trace" => 1 ) );
    $params = $this->xmlArray;
    $response = $client->Product($params);
    return $response;

}

Fatal error:  Uncaught SoapFault exception: [s:Client] Login Failed. in /var/www/html/Consume.php:85

public function Product(){

    $client = new SoapClient( $this->wsdl_url, array( "trace" => 1 ) );
    $params = $this->xmlArray;
    $response = $client->Product($params);
    return $response;

}
