Question

Microsoft MSDN将请求回复操作的最通用服务合同描述为

[ServiceContract]
public interface IUniversalRequestReply
{
    [OperationContract(Action="*", ReplyAction="*")]
    Message ProcessMessage(Message msg);
}

如果我使用basicHttp绑定签订类似下面的合同，那么它将不符合WS-I（使用SOAPUI合规性检查）。

[OperationContract]
Message SomeOperation(Message msg);

我认为最普遍的合同也是最具互操作性的合同。

有人可以解释为什么它不符合WS-I标准吗？更重要的是 - 使用Message类会使服务对Java客户端的消耗更少吗？

感谢使用Message类的任何经验。

编辑在第一次回答后：

这是显示服务合同和运营合同的完整WSDL。

WSI合规性测试失败的原因不是缺少服务合同，而是消息输入本身：

Name of message that failed: {http://tempuri.org/}IUniversalRequestReply_SomeOperation_InputMessage
Message: name={http://tempuri.org/}IUniversalRequestReply_SomeOperation_InputMessage
Part: name=msg
typeName={http://schemas.microsoft.com/Message}MessageBody

因此，使用此Message类不符合WS-I的原因。

Answer 1

原因是服务不是投诉，因为它没有定义任何服务合同。通用意味着此服务可以使用由调用它的任何客户端生成的soap消息。它不会尝试反序列化soap消息，因为它从未定义自己的合同。 WS-I合规性要求服务定义可以用WSDL表示的静态契约。

WCF通用服务合同和WS-Interoperability合规性
