UserNamePasswordValidator中的客户端IP地址

Question

我有一个WCF REST休息服务,由Windows服务托管.它使用自定义UserNamePasswordValidator身份验证.

我想在验证时获取客户端IP地址:

ublic static string GetClientIPAddress()
    {
        try
        {
            var context = OperationContext.Current;
            var prop = context.IncomingMessageProperties;
            var endpoint = prop[RemoteEndpointMessageProperty.Name] as RemoteEndpointMessageProperty;
            return endpoint.Address;
        }
        catch (System.Exception exc)
        {
            Debug.Assert(false,exc.Message);
            return string.Empty;
        }
    }

但它抛出异常,因为在这种情况下上下文为空.我怎么解决这个问题？注意,大多数建议的asp.net兼容模式不是一个选项,我的服务由WIndows服务托管,而不是由IIS托管.

谢谢!

嘿，尝试一下应该有效的解决方案。

private string GetClientIp(HttpRequestMessage request)
{
    if (request.Properties.ContainsKey("MS_HttpContext"))
    {
        return ((HttpContextWrapper)request.Properties["MS_HttpContext"]).Request.UserHostAddress;
    }
    else if (request.Properties.ContainsKey(RemoteEndpointMessageProperty.Name))
    {
        RemoteEndpointMessageProperty prop;
        prop = (RemoteEndpointMessageProperty)this.Request.Properties[RemoteEndpointMessageProperty.Name];
        return prop.Address;
    }
    else
    {
        return null;
    }
}
