您如何确定有效的SoapAction?
我正在使用NuSoap PHP library呼叫webservice. webservice似乎使用.NET；每次调用它时，都会出现有关使用无效的SoapAction header的错误.正在发送的标头是一个空字符串.如何找到服务器期望的SoapAction?
I'm calling a webservice using the NuSoap PHP library. The webservice appears to use .NET; every time I call it I get an error about using an invalid SoapAction header. The header being sent is an empty string. How can I find the SoapAction that the server is expecting?
通过查看服务的WSDL，可以看到正在调用的服务操作期望的SoapAction.对于.NET服务，您可以通过打开Web浏览器访问服务的URL并在末尾附加?wsdl来访问WSDL.
You can see the SoapAction that the service operation you're calling expects by looking at the WSDL for the service. For .NET services, you can access the WSDL by opening a web browser to the url of the service and appending ?wsdl on the end.
在WSDL文档中，您可以看到在操作"节点下(在绑定"下)定义的SoapActions.例如:
Inside the WSDL document, you can see the SoapActions defined under the 'Operation' nodes (under 'Bindings'). For example:
<wsdl:operation name="Execute">
<soap:operation soapAction="http://tempuri.org/Execute" style="document" />
找到要尝试调用的操作的操作节点，然后将在其中找到所需的Soap Action.
Find the operation node for the operation you're trying to invoke, and you'll find the Soap Action it expects there.
