asp.net-mvc - 如何在 ASP.NET MVC API 控制器中获取用户 IP

Question

我已经尝试过，Request.UserHostAddress;但是 API 控制器在请求中没有 UserHostAddress。

Answer 1

IP = ((HttpContextBase)request.Properties["MS_HttpContext"]).Request.UserHostAddress;

Answer 2

我正在使用以下代码，它对我有用....

string ipAddress =   System.Web.HttpContext.Current.Request.UserHostAddress;

Answer 3

据此，更完整的方法是：

private string GetClientIp(HttpRequestMessage request)
{
    if (request.Properties.ContainsKey("MS_HttpContext"))
    {
        return ((HttpContext)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;
    }
}

过去，在 MVC 3 项目（不是 API）上，我们曾经使用以下内容：

string IPAddress = Request.ServerVariables["HTTP_X_FORWARDED_FOR"];

if (String.IsNullOrEmpty(IPAddress))
    IPAddress = Request.ServerVariables["REMOTE_ADDR"];
