Bug #3256

JSON output by ?json query param is invalid

Description

Adding ?json to any directory results in the following JSON, when dirlisting is enabled:

{[{"name":"02","type":"dir","size":4096,"mtime":1704503997},{"name":"03","type":"dir","size":4096,"mtime":1704497695}]}

The curly bracket enclosing the list are not valid JSON.

Here are two valid alternatives:

[{"name":"02","type":"dir","size":4096,"mtime":1704503997},{"name":"03","type":"dir","size":4096,"mtime":1704497695}]

{"items":[{"name":"02","type":"dir","size":4096,"mtime":1704503997},{"name":"03","type":"dir","size":4096,"mtime":1704497695}]}

I prefer the first one: A list as the root element.

Thanks for the report. This patch should fix it. I'll have to test this further on a variety of clients before committing.
