对于我认识的大多数正则表达式专家来说，这是一个简单的问题，但我正在尝试返回句子中某些花括号之间的单词的所有匹配项；但是 Ruby 只返回一个匹配项，我无法弄清楚究竟是为什么.

A simple question for most regex experts I know, but I'm trying to return all matches for the words between some curly braces in a sentence; however Ruby is only returning a single match, and I cannot figure out why exactly.

我正在使用这个例句:

sentence = hello {name} is {thing}

使用此正则表达式尝试返回{name}"和{thing}":

with this regex to try and return both "{name}" and "{thing}":

sentence[/\{(.*?)\}/]

然而，Ruby 只返回{name}".谁能解释为什么这两个词都不匹配?

However, Ruby is only returning "{name}". Can anyone explain why it doesn't match for both words?

推荐答案

你很接近，但使用了错误的方法:

You're close, but using the wrong method:

sentence = "hello {name} is {thing}" sentence.scan(/\{(.*?)\}/) # => [["name"], ["thing"]]
