最佳實踐

Question

我試圖抓住WCF sercue所有的異常有/無SSL/TLS或終點，這樣的事情：

try 
     { 
      ServiceReference.ServiceClient serviceClient = new ChartLogicServiceClient(); 
      serviceClient.Open(); 
      serviceClient.Login("", "", ""); 
     } 
     catch (SecurityNegotiationException negotiationException) 
     { 
      // Could not establish trust relationship for the SSL/TLS secure channel with authority 'localhost'. 
      throw; 
     } 
     catch (ArgumentException argumentException) 
     { 
      // transport wrong config : The provided URI scheme 'https' is invalid; expected 'http'. 
      //if (argumentException.Message == "The provided URI scheme 'http' is invalid; expected 'https'.\r\nParameter name: via") 
      throw; 
     } 
     catch (MessageSecurityException messageSecurityException) 
     { 
      // transport wrong config: The HTTP request was forbidden with client authentication scheme 'Anonymous'. 
      //- HTTP Request Error 
      if (messageSecurityException.InnerException.Message == "The remote server returned an error: (403) Forbidden.") 
      { 
       throw; 
      } 
      else if (messageSecurityException.InnerException.Message == "The remote server returned an error: (404) Forbidden.") 
      { 
       throw; 
      } 
     } 
     catch (EndpointNotFoundException endpointNotFoundException) 
     { 
      // no endpoint was found or IIS on server was turned off 

     } 

我可以檢查可用的WCF服務，而無需調用任何方法（我試過打開（）但不工作）？不知道我是否從WCF服務中捕獲了所有例外情況？我的目的是，如果客戶端通過SSL/TSL或無端點獲得了wcf異常，我應該運行一個小型的實用程序控制臺來修復客戶端上的app.config，以便與wcf端點映射。 我真的需要你的建議。謝謝

您可以隨時嘗試連接到服務的URL並檢查響應代碼。也許不是最好的方式，但它應該工作。例如

GET mysite/myservice.svc 

並檢查HTTP狀態碼。
