PHP / Laravel看起来在制作soapcall时我们没有XML文档

I am trying to do a soap call and I keep getting the following error:

looks like we got no XML document

EDIT error message

here's an example that works fine in my SOAP UI

Here's my array that I send to my soapCall:

$params = [
    'id' => '0000002721',
    'options' => [
                    'returnAttachments' => 'false',
                    'returnPictures'    => 'false',
                    'returnContract'    => 'false'
                 ]
];

Here is the code how I make the soap call

try {
    $options = array(
        'ssl' => array(
            'verify_peer' => false,
            'verify_peer_name' => false,
            'allow_self_signed' => true
        )
    );

    $context = stream_context_create($options);

    $soapClient = new SoapClient(__DIR__ . '/Soap.wsdl', [
        'stream_context' => $context,
        'login' => 'login',
        'password' => 'password',
        'trace' => 1,
            'exceptions' => true,
    ]);

    $soapClient->__setLocation('url');

    $this->soapClient = $soapClient;
} catch (\SoapFault $e) {
    var_dump($e); exit;
}

try {
    $result = $this->soapClient->__soapCall('getMaintenanceObject', $params);
} catch (\SoapFault $e) {
    var_dump($e); exit;
}

SoapClient can be not very expressive when it comes to displaying the errors, add this:

var_dump($this->soapClient->__getLastRequestHeaders()); var_dump($this->soapClient->__getLastResponseHeaders());
