Using the HTTP Response Object
Documentation APIResponse
Exemple de Code
// Sending a response using the Application Object. By default when a
// string is returned in a route the server returns an HTML response.
$app->get('/app-html', function() {
return '<h1>Hello World</h1>';
});
// The Response Object provides many options such as cache control headers
// and secure cookies. This example shows a basic HTML response
// by setting [content()] and returning the Response Object.
$app->get('/res-html', function() {
$res = new \FastSitePHP\Web\Response();
$res->content('<h1>Hello World</h1>');
return $res;
});
// Return a JSON Response by returning an Object or an Array
$app->get('/app-json-object', function() {
$object = new \stdClass;
$object->greeting = 'Hello World';
return $object;
});
$app->get('/app-json-array', function() {
return ['greeting' => 'Hello World'];
});
// Send JSON using the Response Object
$app->get('/res-json', function() {
$res = new \FastSitePHP\Web\Response();
// Set the 'Content-Type' Header.
// The following 3 function calls all set the same value.
// The difference is that [contentType()] is a helper function
// which allows for short-hand values of
// [html, json, jsonp, text, css, javascript, xml].
$res->contentType('json');
$res->contentType('application/json');
$res->header('Content-Type', 'application/json');
// For JSON Content either Objects and Arrays are used
$data = ['greeting' => 'Hello World'];
$res->content($object);
// The helper [json()] can improve code readability as it
// sets both [contentType()] and [content()].
$res->json($data);
return $res;
});
// The Application Object allows for basic Response Headers using the
// [header()] function. This helps avoid creating a Response Object if it
// is not needed, however a response object may be preferred for clarity.
$app->get('/app-text', function() {
$app->header('Content-Type', 'text/plain');
return 'Hello World';
});
// When using the Response Object, properties are set through
// getter/setter functions and are chainable.
$app->get('/res-text', function() {
return (new \FastSitePHP\Web\Response())
->contentType('text')
->content('Hello World');
});
