正则表达式 - 带有两个斜杠的URL链接

I would like to write a very general regexp.

我想写一个非常通用的正则表达式。

It's for:

这是为了：

/something/anything/example

Something, anything and example could be any words. But not it should exclude:

什么，任何东西和例子可以是任何单词。但不应该排除：

/something/anything

Or:

要么：

/something

I know it's basic, but I couldn't find anything for that so far on Google. Thank you!! Tomi

我知道这是基本的，但到目前为止我在Google上找不到任何相关内容。谢谢！！托米

A very basic regex would be

一个非常基本的正则表达式

^(\/[^\/\n]+){3}$

Example : http://regex101.com/r/eF1xF7/1

示例：http：//regex101.com/r/eF1xF7/1

In python, for something like "/something" it'd be more-like

在python中，对于像“/ something”这样的东西，它更像是

import re
def fn(x):
    return re.findall(r'/[a-zA-Z]+',x)

#3

Here's one way using JavaScript:

这是使用JavaScript的一种方式：

var URL = "/something/hello/more"

var re = /\/[^/]+\/*/; // match a "/" then any characters except another "/" 
                      // then another "/" if there if it exists

alert(URL.match(re));
