How to write regular expression for an array of integers?

Question

I have a JSON Path expression - $.[*].incentiveId which will return me an array of integers in the below format

[11791275, 11792924, 11792242, 11793924]

How do I write a regular expression for the above array of integers?

Note: The above array of integers size will vary everytime.

I have written the partial regular expression. ^[[0-9]*,\s and could anyone please help me in completing this regular expression?

What would you like the regular expression to match? The entire array of integers including brackets and commas or just the integers? — bunji, Apr 28 '18 at 14:52
Entire array including numbers [] comma and spaces in between — Srinivasan Ramu, Apr 28 '18 at 14:57
What language or tool? You may try `^\[\d+(?:,\s*\d+)*\]$`. Demo https://regex101.com/r/CzRyPs/1 — revo, Apr 28 '18 at 15:24

It seems Ready API uses Java for Regular Expressions then you are fine with below regex:

^\[\d+(?:,\s*\d+)*\]$

It matches ^ beginning of string, then a literal [ followed by any number of digits. An optional repeating group exists to match comma separated values then a literal ] and $ end of input string.

For my json array with digits it was `\[\d+(?:,\"\d+\")\]` – mialdi98 Jun 16 '22 at 09:59
