我有一个 net.tcp 服务，我想让其他平台（特别是 PHP）可以访问它。为此，我正在使用 http 绑定。

我正在创建一个 http 端点：

ServiceHost svh = new ServiceHost(typeof(MyService));
var httpLocation = "http://" + address + ":4041";
svh.AddServiceEndpoint(typeof(IMyService), new WebHttpBinding(WebHttpSecurityMode.None), 
                                   httpLocation);

svh.AddServiceEndpoint(
                    ServiceMetadataBehavior.MexContractName,
                    MetadataExchangeBindings.CreateMexHttpBinding(),
                    httpLocation + "/mex"
                    );

svh.Open();

现在，当我尝试通过浏览器浏览服务时http://localhost:4041，我得到：

<Fault xmlns="http://schemas.microsoft.com/ws/2005/05/envelope/none">
<Code>
<Value>Sender</Value>
<Subcode>
<Value xmlns:a="http://schemas.microsoft.com/ws/2005/05/addressing/none">a:ActionNotSupported</Value>
</Subcode>
</Code>
<Reason>
<Text xml:lang="en-US">
The message with Action '' cannot be processed at the receiver, due to a ContractFilter mismatch at the EndpointDispatcher. This may be because of either a contract mismatch (mismatched Actions between sender and receiver) or a binding/security mismatch between the sender and the receiver. Check that sender and receiver have the same contract and the same binding (including security requirements, e.g. Message, Transport, None).
</Text>
</Reason>

我究竟做错了什么？

您是否尝试过访问http://localhost:4041/MyService.svc?wsdl？

不确定您的服务在设计上是否符合 REST，这就是您使用 WebHttpBinding 的原因。如果您的服务实际上是 REST-ful，那么它的格式应该是 http://localhost:4041/MyService.svc/MyMethod/MyData，您应该在浏览器上看到结果。基于此ASP.NET 线程，您需要附加一个WebHttpBehavior.

如果您的服务不是 REST-ful，则应BasicHttpBinding根据您的要求考虑（使用常规 SOAP 消息）或其表亲（请参阅此SO 线程）。

希望这可以帮助。

When browsing, make sure to include the full path to the .svc or .asmx along with a trailing ?wsdl.

localhost:4041/ServiceVirtualDirectory/Service.svc?wsdl
