最佳实践

Question

我试图抓住WCF sercue所有的异常有/无SSL/TLS或终点，这样的事情：

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 

     } 

我可以检查可用的WCF服务，而无需调用任何方法（我试过打开（）但不工作）？不知道我是否从WCF服务中捕获了所有例外情况？我的目的是，如果客户端通过SSL/TSL或无端点获得了wcf异常，我应该运行一个小型的实用程序控制台来修复客户端上的app.config，以便与wcf端点映射。 我真的需要你的建议。谢谢

您可以随时尝试连接到服务的URL并检查响应代码。也许不是最好的方式，但它应该工作。例如

GET mysite/myservice.svc 

并检查HTTP状态码。
