c# - WCF 中用于操作契约(Contract)的路由

Question

我是 WCF 的初学者，我创建了一个名为 OrderProcessor 的 RESTful 服务，其中包含三个操作:

bool IsClientActive(string token);
Order ProcessOrder();
string CheckStatus(Guid orderNumber);

我需要就与同一服务相关的几点提出建议和反馈:1. 属性路由:我知道像在 WebAPI 中一样，属性路由在 WCF 中是不可能的，但我想使用以下 URL 创建 api:
<a href="http://localhost" rel="noreferrer noopener nofollow">http://localhost</a>:{portnumber}/OrderProcessor/IsClientActive/{token} - <strong>POST</strong> request for <strong>IsClientActive() method</strong>
<a href="http://localhost" rel="noreferrer noopener nofollow">http://localhost</a>:{portnumber}/OrderProcessor/ProcessOrder - <strong>GET</strong> request for the <strong>ProcessOrder() method</strong>
<a href="http://localhost" rel="noreferrer noopener nofollow">http://localhost</a>:{portnumber}/OrderProcessor/CheckStatus/{orderNumber} - <strong>POST</strong> request for the <strong>CheckStatus() method</strong>


所以，我定义了服务的接口(interface)和实现如下:
契约(Contract) - IOrderProcessor.cs

interface IOrderProcessor
{
    [OperationContract]
    [WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Xml,     ResponseFormat = WebMessageFormat.Json, UriTemplate = "/api/{token}")]
    bool IsClientActive(string token);

    [OperationContract(IsOneWay = false)]
    [WebInvoke(Method = "GET", RequestFormat = WebMessageFormat.Xml, ResponseFormat = WebMessageFormat.Json, UriTemplate = "/api")]
    Order ProcessOrder();

    [OperationContract]
    [WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Xml, ResponseFormat = WebMessageFormat.Json, UriTemplate = "/api/{orderNumber}")]
    string CheckStatus(Guid orderNumber);
}

实现 - OrderProcessor.cs

public class OrderProcessor : IOrderProcessor
    {
        public bool IsClientActive(string token)
        {
            bool status = false;
            try
            {
                if (!string.IsNullOrEmpty(token.Trim()))
                {
                    //Do db checking
                    status = true;
                }
                status = false;
            }
            catch (Exception ex)
            {
                //Log exception
                throw ex;
            }
            return status;
        }

        public Order ProcessOrder()
        {
            Order newOrder = new Order()
            {
                Id = Guid.NewGuid(),
                Owner = "Admin",
                Recipient = "User",
                Info = "Information about the order",
                CreatedOn = DateTime.Now
            };
            return newOrder;
        }

        public string CheckStatus(Guid orderNumber)
        {
            var status = string.Empty;
            try
            {
                if (!(orderNumber == Guid.Empty))
                {
                    status = "On Track";
                }
                status = "Order Number is invalid";

            }
            catch (Exception)
            {
                //Do logging
                throw;
            }

            return status;
        }
    }

Web.config

<system.serviceModel>
    <services>
      <service name="WCF_MSMQ_Service.OrderProcessor" behaviorConfiguration="ServiceBehavior">
        <!-- Service Endpoints -->
        <host>
          <baseAddresses>
            <add baseAddress="http://localhost:4723/"/>
          </baseAddresses>
        </host>

        <!-- Unless fully qualified, address is relative to base address supplied above -->
        <endpoint address="" binding="webHttpBinding" contract="WCF_MSMQ_Service.IOrderProcessor" behaviorConfiguration="Web"></endpoint>
      </service>
    </services>

    <behaviors>
      <serviceBehaviors>
        <behavior name="ServiceBehavior">
          <!-- Enable metadata publishing. -->
          <!-- To avoid disclosing metadata information, set the values below to false before deployment -->
          <serviceMetadata httpGetEnabled="true" httpsGetEnabled="true" />

          <!-- To receive exception details in faults for debugging purposes, set the value below to true.  
          Set to false before deployment to avoid disclosing exception information -->
          <serviceDebug includeExceptionDetailInFaults="false"/>
        </behavior>
      </serviceBehaviors>

      <endpointBehaviors>
        <behavior name="Web">
          <webHttp/>
        </behavior>
      </endpointBehaviors>
    </behaviors>

    <protocolMapping>
        <add binding="basicHttpsBinding" scheme="https" />
    </protocolMapping>   

    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" />
  </system.serviceModel>

问题:我已经实现了所有代码，但是当我尝试使用 Visual Studio 运行它(在浏览器中查看)时，我无法访问上面定义的 URL。例如，我试图检查 URL: http://localhost:4723/OrderProcessor/api它抛出以下错误:

In contract 'IOrderProcessor', there are multiple operations with Method 'POST' and a UriTemplate that is equivalent to '/api/{orderNumber}'. Each operation requires a unique combination of UriTemplate and Method to unambiguously dispatch messages. Use WebGetAttribute or WebInvokeAttribute to alter the UriTemplate and Method values of an operation.

我试图搜索这个错误，有人建议把“[ServiceBehavior(AddressFilterMode = AddressFilterMode.Any)]”在实现类上，但错误仍然存​​在[AddressFilter mismatch at the EndpointDispatcher - the msg with To .有人可以建议一种使用 URL 的方式，就像 WebAPI 方式一样吗？

Answer 1

对于您的以下两种服务方法，只需使用 UriTemplate 即可，

[WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Xml,     ResponseFormat = WebMessageFormat.Json, UriTemplate = "/api/{token}")]
bool IsClientActive(string token);

和

[WebInvoke(Method = "POST", RequestFormat = WebMessageFormat.Xml, ResponseFormat = WebMessageFormat.Json, UriTemplate = "/api/{orderNumber}")]
string CheckStatus(Guid orderNumber);

为了区分你可以通过在UriTemplate中添加方法名来改变它，如下所示

UriTemplate = "/api/isClientActive/{token}"

UriTemplate = "/api/checkStatus/{orderNumber}"
