> The  API discovery service will allow and end point to list of its supported APIs and
their details. Consumers can be CLI clients and wrappers that build on top of the available
list of APIs exposed by a Cloudstack instance.
> The response structure is an array of apis with:
> name (name of the api command), description (or docstring), since (version since the
api was introduced, empty suggests it was pre 3.x), isasync (true if api is asynchronous),
array of dictionary of params.
> The structure for list of params is:
> name (name of the parameter), description (or doctoring for the parameter), type (kind
of parameter, bool, long, map, uuid etc.), length (allowed max length for the param, default
is 255), required (if param is
> +necessary for making an api request), since (CloudStack versions no. in which param
was introduced, empty suggests it was introduced when the api was introduced).
> Example response:
> { "listapisresponse" : { "count":301 ,"apis" : [ {"name":"listAsyncJobs","description":"Lists
all pending asynchronous jobs for the
> +account.","since":"","isasync":false,"param":[{"name":"pagesize","description":"","type":"INTEGER","length":255,"required":false,"since":""},{"name":"domainid","description":"list
only resources belonging to
> +the domain specified","type":"UUID","length":255,"required":false,"since":""},{"name":"listall","description":"If
set to false, list only resources belonging to the command's caller; if set to true - list
> +resources that the caller is authorized to see. Default value is false","type":"BOOLEAN","length":255,"required":false,"since":""},{"name":"account","description":"List
resources by account. Must be used with
> +the domainId parameter.","type":"STRING","length":255,"required":false,"since":""},{"name":"startdate","description":"the
start date of the async
> +job","type":"TZDATE","length":255,"required":false,"since":""},{"name":"page","description":"","type":"INTEGER","length":255,"required":false,"since":""},{"name":"isrecursive","description":"defaults
to false,
> +but if true, lists all resources from the parent specified by the domainId till leaves.","type":"BOOLEAN","length":255,"required":false,"since":""},{"name":"keyword","description":"List
by
> +keyword","type":"STRING","length":255,"required":false,"since":""}]}
> This information is pre-cached during load time (when mgmt server starts) as a list of
response by the plugin and it takes about 677 milliseconds to generate mapping of apiname
and cmd class and 89 milliseconds
> +to pre cache the response object:
> INFO  [cloudstack.discovery.ApiDiscoveryServiceImpl] (main:) Generated apiname, cmd class
mapping in 677 ms
> INFO  [cloudstack.discovery.ApiDiscoveryServiceImpl] (main:) Discovered api, precached
response in 89 ms
> The plugin is an adapter, also a pluggable service and provides an api cmd class with
apiname listApis (suggest a better name, listApis made sense as the response is list of Apis
+ docs available on the CS mgmt
> +server to the user).
> Based on parameter annotation, we can also return information of related apis for a particular
apis (based on response class, say all vm related apis have same response class) and also
suggest apis to get the
> +parameter (wherever applicable, we know entityType, so we know the response class).
Do we want such a feature?
> Since, this is a plugin and has its own commands.properties, one can blacklist or change
role based acl (in commands.properties) or disable plugin (from components.xml) to controls
or use this plugin as a
> +starting point to make their own discovery service (not just apis, think discovery of
resources etc.).
