匹配字符串的一部分并检索不接近的数字正则表达式

Question

This is my string:

setLocation('http://www.example.com/shop/checkout/cart/add/uenc/aHR0cDovL3d3dy5mYXJtYWNpYWNhbG9pbmkuY29tL3Nob3Av/product/100/form_key/CxWB0lZZuNAENjz5/')

What I need ot do is match /checkout/cart/add and catch the number /100/ .
This is what I have tried:

checkout\/cart\/add.+\/(100)\/

and it works, but if I try to extend it to any number:

checkout\/cart\/add.+\/([1-9]+)\/

it doesn't work anymore

REGEX101

Answer 1

将字符类中的1更改为0 ，以便它也与数字0匹配。

checkout\/cart\/add.+\/([0-9]+)\/

Answer 2

您还可以对数字\\d使用简写表示法

checkout\/cart\/add.+\/(\d+)\/
