UriTemplate WCF

Question

是否有一種簡單的方法可以在同一個定義中擁有多個UriTemplates。

[WebGet(UriTemplate = "{id}")] 

例如，我希望/ API/{id}和/ API/{id} /調用相同的東西。如果最後有/沒有，我不希望它重要。

Answer 1

我發現要做到這一點的最簡單的方法是超載功能as explained here。

Answer 2

不是很簡單，但您可以在您的行爲中使用操作選擇器去除尾部的「/」，如下例所示。

public class StackOverflow_6073581_751090 
{ 
    [ServiceContract] 
    public interface ITest 
    { 
     [WebGet(UriTemplate = "/API/{id}")] 
     string Get(string id); 
    } 
    public class Service : ITest 
    { 
     public string Get(string id) 
     { 
      return id; 
     } 
    } 
    public class MyBehavior : WebHttpBehavior 
    { 
     protected override WebHttpDispatchOperationSelector GetOperationSelector(ServiceEndpoint endpoint) 
     { 
      return new MySelector(endpoint); 
     } 

     class MySelector : WebHttpDispatchOperationSelector 
     { 
      public MySelector(ServiceEndpoint endpoint) : base(endpoint) { } 

      protected override string SelectOperation(ref Message message, out bool uriMatched) 
      { 
       string result = base.SelectOperation(ref message, out uriMatched); 
       if (!uriMatched) 
       { 
        string address = message.Headers.To.AbsoluteUri; 
        if (address.EndsWith("/")) 
        { 
         message.Headers.To = new Uri(address.Substring(0, address.Length - 1)); 
        } 

        result = base.SelectOperation(ref message, out uriMatched); 
       } 

       return result; 
      } 
     } 
    } 
    public static void Test() 
    { 
     string baseAddress = "http://" + Environment.MachineName + ":8000/Service"; 
     ServiceHost host = new ServiceHost(typeof(Service), new Uri(baseAddress)); 
     host.AddServiceEndpoint(typeof(ITest), new WebHttpBinding(), "").Behaviors.Add(new MyBehavior()); 
     host.Open(); 
     Console.WriteLine("Host opened"); 

     WebClient c = new WebClient(); 
     Console.WriteLine(c.DownloadString(baseAddress + "/API/2")); 
     Console.WriteLine(c.DownloadString(baseAddress + "/API/2/")); 

     Console.Write("Press ENTER to close the host"); 
     Console.ReadLine(); 
     host.Close(); 
    } 
}

這只是部分有幫助的，但新的WCF Web API庫有一個屬性上HttpBehavior稱爲可以設置爲忽略或重定向TrailingSlashMode。
