what is going wrong?
On some forums people discussed this matter and said it could be resolved by adding
<wsdl:fault>
in wsdl but in my case fault is already present in wsdl.
回答1:
Add the following code to your bindings
<wsdl:fault name="fault">
<soap:fault use="literal" name="fault" />
</wsdl:fault>
Just make sure that name of the fault is changed to whatever is your custom fault name is
