描述

Tested on version 6.9.4

Stringify with arrayFormat: comma encodes objects inside arrays as [object Object]

I took this code from the examples:

qs.stringify({ a: { b: { c: 'd', e: 'f' } } });
// 'a[b][c]=d&a[b][e]=f'

and added an array around the inside object

qs.stringify({ a: { b: [{ c: 'd', e: 'f' }] } }, { encode: false, arrayFormat: 'comma' })
// 'a[b]=[object Object]'

The inside data is lost this way.

I tried the allowDots setting too, but that didn't fix anything.

I'm not sure what the output should be like exactly, but this is unusable right now. In my project I did Array.map(p => ${p.ID}::${p.Value}), but that's very specific and I'm unsure if the :: is a good seperator.

研究方向
Investigate the stringify function's handling of arrayFormat: 'comma' in the source code. Determine the expected behavior for nested objects inside arrays under this format. Review the discussion in the issue comments (e.g., maintainer's stance) and consider both preserving object structure or opting for a consistent string representation. Possibly propose a new option or fix to properly serialize objects as a string representation like JSON or a custom format.
