出了什么问题?

在一些论坛上，人们对此问题进行了讨论，并表示可以通过添加

On some forums people discussed this matter and said it could be resolved by adding

<wsdl:fault>

在wsdl中，但就我而言，wsdl中已经存在故障.

in wsdl but in my case fault is already present in wsdl.

推荐答案

将以下代码添加到绑定中

Add the following code to your bindings

<wsdl:fault name="fault">
  <soap:fault use="literal" name="fault" />
</wsdl:fault>

只需确保将故障名称更改为您的自定义故障名称为

Just make sure that name of the fault is changed to whatever is your custom fault name is
