我用PHP编写了soap客户端和soap服务器:
Server.php
// Initializing code is omitted
$server = new SoapServer('http://wsdl.localhost:8888/calculator_service.wsdl');
$server->setClass('CalculatorGateway');
$server->handle();
Client.php
// Initializing code is omitted
$request = new Request();
$request->data = new DataObject();
$request->data->sourceValue = 10;
$request->data->modifyBy = 5;
$client = new SoapClient(
'http://wsdl.localhost:8888/calculator_service.wsdl',
['soap_version' => SOAP_1_2, 'classmap' => [
'Response' => 'Response'
]]
);
// $argv[1] must be one of "add" or "sub"
$response = $client->$argv[1]($request);
echo 'Result: ' . $response->result;

我的问题:无论我请求什么操作，总是第一个，它在绑定部分声明，将被执行。例如，在这种情况下，即使我请求"sub"，也会执行"add"操作。作为实验，我可以像这样改变顺序:
<binding name="CalculatorServiceBinding" type="tns:CalculatorServicePortType">
<operation name="sub">
<!-- sub operation used to be on the second place -->
</operation>
<operation name="add">
<!-- add operation used to be on the first place -->
</operation>
</binding>
现在"sub"操作一直在执行。
有什么问题吗?装订部分我说错了吗?
解决方法很简单。Style属性必须出现在soap:binding元素中。这样的:
<soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http" />
