问题描述

是否可以获取发布新记录的用户的 MAC 地址?
如果我有名为 mac_address 的列，我如何编写控制器以将 MAC 地址放入该列?

Is it possible to get the MAC address of a user that posts a new record?
If I had column called mac_address, how can I write my controller to put the MAC address into that column?

推荐答案

用户的 mac 地址不是 Web 请求的一部分.

A user's mac address is not part of the web request.

我知道这不是您的问题，但您可以使用请求对象获取他们的 IP 地址:

I know it's not your question, but you can get their IP address using the request object:

request.ip

在您的 create 操作中，您可能有如下内容(假设您有一列 ip_address):

In your create action, you could have something like the following (assuming you have a column ip_address):

def create
  @item = Item.new(params[:item])
  @item.ip_address = request.ip
  if @item.save
    ...
  end
end
