我在WCF一個初學者,創建了一個稱爲訂單處理器RESTful服務有三種操作:路由在WCF的業務合同
bool IsClientActive(string token);
Order ProcessOrder();
string CheckStatus(Guid orderNumber);
我需要在與同一服務幾點建議和反饋: 1.屬性路由:我知道像的WebAPI,屬性路由是不是在WCF可能的,但我想創建具有以下URL的API: http://localhost :{portnumber}/OrderProcessor/IsClientActive/{token} - POST request for IsClientActive() method http://localhost :{portnumber}/OrderProcessor/ProcessOrder - GET request for the ProcessOrder() method http://localhost :{portnumber}/OrderProcessor/CheckStatus/{orderNumber} - POST request for the CheckStatus() method
所以,我定義爲服務的接口和實現如下:
個 合同 - 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);
}
實現 - 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;
}
}
的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>

</system.serviceModel>
問題: 我已經實現了所有的代碼,但是當我嘗試使用Visual Studio運行它(在瀏覽器中查看),我無法訪問上面定義的URL。例如,我想查詢的網址: http://localhost:4723/OrderProcessor/api 它拋出以下錯誤:
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.
我試圖尋找這個錯誤,有人建議把 「[ServiceBehavior(AddressFilterMode = AddressFilterMode.Any) ]「在實施,智力班,但錯誤仍然在這裏[AddressFilter mismatch at the EndpointDispatcher - the msg with To。有人可以建議一種像WebAPI一樣使用URL的方法嗎?
正如@Mukesh Modhvadiya所建議的那樣,我一直在爲IsClientActive()保留相同的UriTemplate,和CheckStatus()方法。解決方案是指定不同的名稱,它的工作。 –
