获取客户端的IP地址 [英] Get the client's IP address

问题描述

以前在其他版本的asp.net中，我使用了HttpRequest的这些属性:

Previously in other version of asp.net, I used these properties of HttpRequest:

Request.ServerVariables["REMOTE_ADDR"]
Request.UserHostAddress

如何在ASP.NET Core中实现相同的目标?

How can I achieve the same in ASP.NET Core?

推荐答案

您可以使用IHttpContextAccessor:

private IHttpContextAccessor _accessor;
public Foo(IHttpContextAccessor accessor)
{
    _accessor = accessor;
}

现在您以这种方式获取IP地址"

Now you get IP address this way"

var ip = _accessor.HttpContext.Connection.RemoteIpAddress.ToString();
