正则表达式在花括号之间获取字符串“{我想要花括号之间的内容}” [英] Regex to get string between curly braces "{I want what's between the curly braces}"

问题描述

不幸的是，尽管我一年中至少有一次尝试学习正则表达多年，但我总是忘记，因为我很少使用它们。今年我的新年决心是不再尝试再学习正则表达式 - 所以今年为了让我免于流泪，我会把它交给Stack Overflow 。 （去年圣诞节混音）。

Unfortunately, despite having tried to learn regex at least one time a year for as many years as I can remember, I always forget as I use them so infrequently. This year my new year's resolution is to not try and learn regex again - So this year to save me from tears I'll give it to Stack Overflow. (Last Christmas remix).

我想以这种格式传递一个字符串 {getThis} ，并且返回字符串 getThis 。任何人都可以帮助坚持我的新年决议吗？

I want to pass in a string in this format {getThis}, and be returned the string getThis. Could anyone be of assistance in helping to stick to my new year's resolution?

推荐答案

如果您的字符串将始终采用该格式，则为正则表达式是过度杀伤：

If your string will always be of that format, a regex is overkill:

>>> var g='{getThis}';
>>> g.substring(1,g.length-1)
"getThis"
