如何在 ruby​​ 中做一个安全的连接路径名? [英] How to do a safe join pathname in ruby?

问题描述

我的 Rails 开发环境基于 Windows，我的生产环境基于 Linux.

My Rails development environment is Windows-based, and my production environment is Linux-based.

可能会使用 VirtualHost.假设需要在 /public 文件夹中使用 File.open('/tmp/abc.txt', 'r') 引用一个文件名.

It's possible that VirtualHost will be used. Assume that one filename needs to be referenced in the /public folder with File.open('/tmp/abc.txt', 'r').

——但在 Windows 中它应该是 C:\tmp\abc.txt.如何进行正确的路径连接来处理两种不同的环境?

—but in Windows it should be C:\tmp\abc.txt. How can I do a correct path join to handle the two different environments?

prefix_tmp_path = '/tmp/'
filename = "/#{rand(10)}.txt"

fullname = prefix_tmp_path + filename # /tmp//1.txt <- but I don't want a double //

当 prefix_tmp_path = "C:\tmp\" 我得到 C:\tmp\/1.txt

处理这两种情况的正确方法是什么?

What is the correct way to handle both cases?

推荐答案

我推荐使用 File.join

I recommend using File.join

>> File.join("path", "to", "join")
=> "path/to/join"
