Hi Jiang, Not sure if this will answer your questions but here are the API autogenerated docs <https://en.wikipedia.org/w/api.php>.
Also, if you don't get the information you need here, you might want to consult the mediawiki-api maling list<https://lists.wikimedia.org/mailman/listinfo/mediawiki-api>for more details on the API.
