如何从WCF服务应用程序获取客户端的地址？

Question

How can I get a client's address from a WCF Service Application? Also, is there an event raised when a client connects, possibly with address information?

Answer 1

In 3.0, this is quite hard; but was improved in 3.5 ( read Detect Client IP in WCF 3.5 ). I'm not aware of an event, though.

Answer 2

Which address are you looking for? The IP address?

If so, I hope you're aware of the limitations on that - it won't be accurate if the client's on the other side of a NAT device or Internet proxy.

Answer 3

If System.Web.HttpContext.Current.Request.UserHostAddress isn't null, then it has the remote address. But that might be a proxy or load balancer (the case I have in our production environment).

Answer 4

如果WCF主机提供获取服务请求者IP的方法会更容易 - 这样您就可以调用该方法来获取原始请求者。

Answer 5

您可以使用类似于OperationContext.Current.IncomingMessageHeaders.To.Host
