Issue #89 feat: Category plugin enhancements

[manojLondhe]

• Update get single category api
• Update get category list api

[coolbung]

Can this be /categories/all/:extension. The value of extension will be available in the id param. Not ideal, but that makes the sef URL semantic.

[manojLondhe]

need router support here as well as described at https://github.com/techjoomla/com_api-plugins/pull/90/files#r245647296 @coolbung

[coolbung]

Please support getting the category by either id or alias, so both /categories/category/59 and /categories/category/sports should work

@coolbung

How do we differentiate between if an alias is set or an id is set?

Consider an example with a

1. category having id as 2
2. and another category having alias as sports-2

Current com_api router only handles id, how will it work for alias?

in above two cases:

$id = $input->get('id', 0, 'int'); will return 2 as $id

[coolbung]

I can think of 2 options

1. Don't typecast the id as int. if the id is numeric assume it to be a id, otherwise assume it to be alias.
2. Support a X-Identifier header. The value for this header can be id (default) or alias. This tells the plugin which record to update. This method is already implemented in the user edit plugin by @twsvaishali

3. or can we add trigger to let extend com_api router, something like

onApiRoute (&segments, &$vars)

and let plugins set vars as needed

I tried this out and I got both id and alias to work
