This repo contains all the code used for the demo presented by Group A of UNIPA (Università degli Studi di Palermo) for "Samsung Innovation Campus 2021 Smart Things Edition" in Palermo. Eventually 3 of the 4 members of Group A (atmoeyes) won the edition.

Below are developement notes.

{
    "backendUrl": "https://emanuelemessina.altervista.org/uni/ssmic2021/atmoeyes/backend"
}

1. Calls to /backend are redirected to kernel.php via .htaccess RewriteRule.
2. kernel.php - calls db, calls router.
3. /db.php - initializes db connection, declares db methods.
4. /router/router.php - declares route matching methods, calls routes.php.
5. /router/routes.php - sets application/json response header, calls declared routes, which are then parsed by the router. If no match is found, 404 is thrown.
6. When a match is found, execution is passed to the matched route controller.

$input_schema = [
    "id" => "int",
    "value" => "int"
];

$qq = new QuickQuery('json-input', $input_schema);
$validated_data = $qq->getValidatedData();
$response = $qq->update(
    'data', // table
    ['value'], // fields to update
    [ // where clause
        'id' => $validated_data['id'] 
    ]);

echo json_encode($response);

Validation is automatically done and all errors are reported in the response.
Table names are already prefixed with 'atmoeyes_'.

get('/data/aqi/$optional_get_param', 'aqi-data.php'); 

• Controller files are placed under /controllers.
• Optional GET parameters are accessible in the controller via $parameters array.
