使用 IDispatchMessageInspector 获取请求的远程地址
我正在尝试关注此博客文章： http://blogs.msdn.com/b/carlosfigueira/archive/2011/04/19/wcf-extensibility-message-inspectors.aspx
我的目标是以某种方式获取远程地址传入请求的地址，但由于某种原因，该地址要么在任何参数中都看不到，要么为空。
这是我正在实现的接口：
public interface IDispatchMessageInspector
{
object AfterReceiveRequest(ref Message request, IClientChannel channel, InstanceContext instanceContext);
void BeforeSendReply(ref Message reply, object correlationState);
}
我尝试获取远程地址的方法是 AfterReceiveRequest。我检查了参数 request 和 channel。另外，channel.RemoteAddress 似乎是它应该在的位置，但由于某种原因该属性为 null。 request 参数也为 null，但我猜这是因为我正在执行 GET 而不是 POST。
下面是我调用来测试这一点的方法的签名。
[OperationContract, WebGet( UriTemplate = "{*path}", ResponseFormat = WebMessageFormat.Json)]
string[] GetList(string path);
I'm trying to follow this blog post: http://blogs.msdn.com/b/carlosfigueira/archive/2011/04/19/wcf-extensibility-message-inspectors.aspx
My aim is to somehow get the remote address of the incoming request, but for some reason the address either is nowhere to be seen in any of the parameters, or is null.
Here's the interface I'm implementing:
public interface IDispatchMessageInspector
{
object AfterReceiveRequest(ref Message request, IClientChannel channel, InstanceContext instanceContext);
void BeforeSendReply(ref Message reply, object correlationState);
}
The method I'm trying to get the remote address in is AfterReceiveRequest. I've checked both parameters request and channel. Also, it seems that channel.RemoteAddress is where it should be, but that property is null for some reason. The request parameter is also null, but I'm guessing that's because I'm doing a GET and not a POST.
Below is the signature of the method I'm invoking to test this out.
[OperationContract, WebGet( UriTemplate = "{*path}", ResponseFormat = WebMessageFormat.Json)]
string[] GetList(string path);

使用
OperationContext.Current.IncomingMessageHeaders.From< /a>或
(OperationContext.Current.IncomingMessageProperties[RemoteEndpointMessageProperty.Name] as RemoteEndpointMessageProperty).Address或
HttpContext.Current.Request.UserHostAddress（请注意，这需要设置Use
OperationContext.Current.IncomingMessageHeaders.FromOR
(OperationContext.Current. IncomingMessageProperties[RemoteEndpointMessageProperty.Name] as RemoteEndpointMessageProperty).AddressOR
HttpContext.Current.Request.UserHostAddress(BEWARE this one requires setting<serviceHostingEnvironment aspNetCompatibilityEnabled="true"/>)使用来自
IDispatchMessageInspector实现的代码：Use this from
