读本地文件..... [英] Read local file.....

问题描述

所以我知道我认为读取本地文件作为安全问题的所有限制。但是我正在构建一个用户将在其内部网页下登录的网络应用。我需要一个文本文件，所以我知道它来自哪个设备用于跟踪。有没有办法绕过这个来读取本地机器上的文件，或者我可以获取设备的另一个值（示例MAC地址）？所以像设备123456我会有一个数据库，说这是大鸟笔记本电脑等。

我现在读它的文件，但它的本地服务器端文件。不是设备。



谢谢



我尝试了什么：



我使用streamReader读取服务器端文件，但这不是我想要的。通常你不想在本地做这个，但在这种情况下我做。

So I know of all the restrictions I think of reading a local file as its a security issue. However I am building a web "app" that a user will sign in under ( its an internal web page). I need a text file so I know what device its coming from for tracking. Is there anyway to get around this to read the file on the local machine or can I grab another "value" ( example MAC address ) of the device? So like device 123456 I would have a database that says this is "Big Birds" laptop etc..
I have it reading a file now but its the local server side file. Not the devices.

Thanks

What I have tried:

I have used the streamReader to read a server side file but that is not what I want. Normally you would not want to do this local but in this case I do.

推荐答案

你无法在浏览器中从设备中读取文件。



您也无法访问设备上的任何硬件，包括MAC地址。此外，MAC地址不能用作计算机或用户的唯一标识符。没有足够的地址可以做到这一点。



如果您正在跟踪用户，请使用用户电子邮件地址构建标识符。把它标识在一个cookie中，你可以在下次访问该网站时识别该用户。



识别一台机器要困难得多，因为可以很容易地删除cookie并且是基于用户的，而不是基于机器的。



您可能想要阅读这个主题 [ ^ ]了解更多信息。

You cannot read a file from the device in the browser.

You also cannot get at any of the hardware on the device, including the MAC address. Also, a MAC address can NOT be used as a unique identifier for a machine or user. There are simply not enough possible addresses to do that.

If you're tracking users, build an identifier using the users email address. Put that identified in a cookie and you can ID that user the next time they visit the site.

Identifying a machine is a LOT harder because cookies can be deleted very easily and are user-based, not machine based.

所以可以我在根目录中的PC上添加一个文件或类似的东西？我可以根据需要安装软件，因为我会设置所有这些。我们将使用基于Windows的平板电脑。

So could I add a file on the "PC" in the root directory or something like that? I can install software if needed as I will be setting all these up anyways. Its a windows based tablet is what we will be using.
