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?
推薦答案
通過查看服務(wù)的 WSDL，您可以看到您正在調(diào)用的服務(wù)操作期望的 SoapAction.對于 .NET 服務(wù)，您可以通過在 Web 瀏覽器中打開服務(wù)的 URL 并在末尾附加 ?wsdl 來訪問 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 文檔中，您可以看到在操作"節(jié)點下(在綁定"下)定義的 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" />
找到您嘗試調(diào)用的操作的操作節(jié)點，您會在那里找到它期望的 Soap Action.
Find the operation node for the operation you're trying to invoke, and you'll find the Soap Action it expects there.
