在Web API身份验证过滤器中捕获请求IP地址 [英] Capture request IP Address in Web API Authentication Filter

问题描述

我想捕获调用我的Web API服务的客户端的IP地址.我试图在我创建的自定义身份验证过滤器中捕获该IP地址.

I would like to capture the IP Address of the client that calls my Web API service. I am trying to capture that IP address in a custom Authentication Filter that I have created.

请求IP地址是否可以从 HttpActionContext 获得?

Is the request IP address available from the HttpActionContext ?

我似乎找不到它.

身份验证过滤器在捕获发出请求的客户端IP地址的位置错误吗?

Is the Authentication Filter the wrong place where to capture the IP address of the client making the request ?

推荐答案

我最近找到了以下扩展方法:

I recently found the following extension method for that:

public static string GetClientIpAddress(this HttpRequestMessage request)
{
    if (request.Properties.ContainsKey("MS_HttpContext"))
    {
        return IPAddress.Parse(((HttpContextBase)request.Properties["MS_HttpContext"]).Request.UserHostAddress).ToString();
    }
    if (request.Properties.ContainsKey("MS_OwinContext"))
    {
        return IPAddress.Parse(((OwinContext)request.Properties["MS_OwinContext"]).Request.RemoteIpAddress).ToString();
    }
    return null;
}

您现在可以致电:

HttpActionContext.Request.GetClientIpAddress();
