使用WCF客户端访问RESTful服务时访问HTTP状态代码

感谢此答案，现在，我可以使用WCF客户端成功调用JSON RESTful服务.但是该服务使用HTTP状态代码来通知结果.我不确定如何访问这些状态代码，因为我在调用服务时仅在客户端收到异常.即使该异常也不具有HTTP状态代码属性.它只是埋在异常消息本身中.

Thanks to this answer, I am now able to successfully call a JSON RESTful service using a WCF client. But that service uses HTTP status codes to notify the result. I am not sure how I can access those status codes since I just receive an exception on client side while calling the service. Even the exception doesn't have HTTP status code property. It is just buried in the exception message itself.

问题是，在调用服务时如何检查/访问响应的HTTP状态代码.

So the question is, how to check/access the HTTP status code of response when the service is called.

推荐答案

作为一个捷径，您可以访问状态代码，如下所示:

As a quick win, you can access the status code in the exception like this:

try { client.DoSomething(); // call the REST service } catch (Exception x) { if (x.InnerException is WebException) { WebException webException = x.InnerException as WebException; HttpWebResponse response = webException.Response as HttpWebResponse; Console.WriteLine("Status code: {0}", response.StatusCode); } }

也许有一个带有消息检查器的解决方案.但是我还没有弄清楚.

Maybe there's a solution with a message inspector. But I haven't figured it out yet.
