将整个文本文件作为单个字符串读取的合理方法是什么？ [英] What's a reasonable way to read an entire text file as a single string?

问题描述

我确信这很容易;我无法立即从Google找到答案

I am sure this is an easy one; I just couldn't find the answer immediately from Google.

我知道我可以做到这一点（对吧？）：

I know I could do this (right?):

text = ""
File.open(path).each_line do |line|
    text += line
end

# Do something with text

但这似乎有点过分，不是吗？或者这是用Ruby做的方式？

But that seems a bit excessive, doesn't it? Or is that the way one would do it in Ruby?

推荐答案

IO.read（） ？

编辑： IO.read（），作为额外的奖励，为您关闭文件。

IO.read(), as an added bonus, closes the file for you.
