I am thinking about adding a JSON output format to mod_status and
mod_info as an option controlled by a query string parameter.
Since writing simple data structures from these modules is much simpler
than parsing and processing a JSON structure, I would expect it to be
based on simple ap_rputs() and ap_rprintf() like we already use it for
auto (text) and HTML output. IMHO no need for a JSON library just for
this use case.
Of course, this will slightly bloat the code with "if" statements and
roughly double the amount of ap_rputs() and ap_rprintf().
For mod_status this probably means introduction of a new AP_STATUS_JSON
value, so that in theory other modules could in the future update their
status extensions with JSON support. In the meantime it might mean, that
if a modules extends mod_status output, the result when asking for JSON
output is no valid JSON (mix between mod_status JSON and mod_something
providing HTML or text). For our own modules, especially mod_proxy, this
can of course be fixed (and I will fix this). For mod_info, we do not
have such an extension problem wrt. 3rd-party modules.
Any comments up-front before I try to prototype this?
+1 ;-)
Thanks and regards,
Rainer
