單個WCF .svc，連接多個客戶端

Question

我創建了一個帶有多個接口的WCF服務。這一次爲多個用戶提供服務。

我是否需要更改ServiceContract或ServiceBehaviour中的任何內容以確保兩個客戶端之間沒有「交叉」？

的的ServiceContract留空，但在我的.svc的ServiceBehaviour是像這樣：

<ServiceBehavior(InstanceContextMode:=InstanceContextMode.PerCall, AutomaticSessionShutdown:=True, 
      ConcurrencyMode:=ConcurrencyMode.Single, IncludeExceptionDetailInFaults:=True)> 

任何幫助是極大的讚賞。

Answer 1

那麼幾個小時的挖掘後，以迫使它在每次調用進行身份驗證，因此不能與其他情況下進行干預，我把這個綁定：

<message clientCredentialType="UserName" 
algorithmSuite="TripleDesSha256Rsa15" 
establishSecurityContext="false" /> 

重要的是establi shSecurityContext =「false」，默認值爲true，因此它會記住上次建立的登錄，當您將其設置爲false時，它會在每次調用時重新進行身份驗證。爲了提高效率，您需要驗證代碼才能保持光滑。
