Asp.net Core中的UserHostAddress

Question

什么是旧的Asp.Net 5中的等价物HttpContext.Request.UserHostAddress？

我试过this.ActionContext.HttpContext但找不到UserHostAddress和ServerVariables属性.

谢谢

Answer 1

如果您有权访问HttpContext,可以从Connection属性获取本地/远程IpAddress,如下所示:

var remote = this.HttpContext.Connection.RemoteIpAddress;
var local = this.HttpContext.Connection.LocalIpAddress;

Answer 2

自最初的答案发布以来,这已经发生了变化.现在通过访问它

httpContext.Features.Get<IHttpConnectionFeature>()?.RemoteIpAddress

Answer 3

HttpRequest.UserHostAddress给出远程客户端的IP地址.在ASP.NET Core 1.0中,您必须使用HTTP连接功能才能获得相同的功能.HttpContext有GetFeature<T>可用于获取特定功能的方法.例如,如果要从控制器操作方法中检索远程IP地址,可以执行以下操作.

var connectionFeature = Context
           .GetFeature<Microsoft.AspNet.HttpFeature.IHttpConnectionFeature>();

if (connectionFeature != null)
{
    string ip = connectionFeature.RemoteIpAddress.ToString();
}
