PHP SoapClient - _SoapCall 必须将参数包装在方法名称中

Question

我有以下肥皂网络服务：

<soap:Envelope xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
   <soap:Body>
     <Customer_Get xmlns="http://example.com/">
       <token>string</token>
       <customerId>string</customerId>
     </Customer_Get>
   </soap:Body>
</soap:Envelope>

以下调用不起作用：

$soap = new SoapClient('link/to/.wsdl');
$result = $soap->__soapCall('Customer_Get', ['token' => 'asdad', 'customerId' => 1]);

但是，当我将参数数组包装在带有方法名称的数组中时，它可以工作：

$soap = new SoapClient('link/to/.wsdl');
$result = $soap->__soapCall('Customer_Get', ['Customer_Get' => ['token' => 'asdad', 'customerId' => 1]]); 

为什么我需要将参数包装在方法名称中？

Answer 1

因为这个电话

$result = $soap->__soapCall('Customer_Get', ['Customer_Get' => ['token' => 'asdad', 'customerId' => 1]]);

是这里调用的简写（带有“参数”）：

$result = $soap->__soapCall('Customer_Get', ['parameters' => ['Customer_Get' => ['token' => 'asdad', 'customerId' => 1]]]);
