睇 MediaWiki:Api-help-templatedparams 嘅原碼

Templated parameters support cases where an API module needs a value for each value of some other parameter. For example, if there were an API module to request fruit, it might have a parameter <var>fruits</var> to specify which fruits are being requested and a templated parameter <var>{fruit}-quantity</var> to specify how many of each fruit to request. An API client that wants 1 apple, 5 bananas, and 20 strawberries could then make a request like <kbd>fruits=apples|bananas|strawberries&apples-quantity=1&bananas-quantity=5&strawberries-quantity=20</kbd>.
