Ciao a tutti, ho cercato alcuni esempio on line per capire la soluzione ideale per strutturare un'API. Tra tutte, la più completa mi sembra questa (allegata) ma non capisco come "utilizzarla".... inteso come chiamare il comando (quindi passare l'azione da eseguire all'API) (esempio deleteuser) e ritornare un JSON con un elenco di valori. Anche seguendo il commento iniziale mi perdo.
Mi potreste dare qualche dritta?
Codice PHP:
<?php
/*
This is an example class script proceeding secured API
To use this class you should keep same as query string and function name
Ex: If the query string value rquest=delete_user Access modifiers doesn't matter but function should be
function delete_user(){
You code goes here
}
Class will execute the function dynamically;
usage :
$object->response(output_data, status_code);
$object->_request - to get santinized input
output_data : JSON (I am using)
status_code : Send status message for headers
Add This extension for localhost checking :
Chrome Extension : Advanced REST client Application
URL : [url]https://chrome.google.com/webstore/detail/hgmloofddffdnphfgcellkdfbfbjeloo[/url]
I used the below table for demo purpose.
CREATE TABLE IF NOT EXISTS `users` (
`user_id` int(11) NOT NULL AUTO_INCREMENT,
`user_fullname` varchar(25) NOT NULL,
`user_email` varchar(50) NOT NULL,
`user_password` varchar(50) NOT NULL,
`user_status` tinyint(1) NOT NULL DEFAULT '0',
PRIMARY KEY (`user_id`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=1 ;
