PHP 클래스 Symfony\Component\HttpKernel\Cache\Cache

__construct() 공개 메소드

The available options are: * debug: If true, the traces are added as a HTTP header to ease debugging * default_ttl The number of seconds that a cache entry should be considered fresh when no explicit freshness information is provided in a response. Explicit Cache-Control or Expires headers override this value. (default: 0) * private_headers Set of request headers that trigger "private" cache-control behavior on responses that don't explicitly state whether the response is public or private via a Cache-Control directive. (default: Authorization and Cookie) * allow_reload Specifies whether the client can force a cache reload by including a Cache-Control "no-cache" directive in the request. Set it to true for compliance with RFC 2616. (default: false) * allow_revalidate Specifies whether the client can force a cache revalidate by including a Cache-Control "max-age=0" directive in the request. Set it to true for compliance with RFC 2616. (default: false) * stale_while_revalidate Specifies the default number of seconds (the granularity is the second as the Response TTL precision is a second) during which the cache can immediately return a stale response while it revalidates it in the background (default: 2). This setting is overridden by the stale-while-revalidate HTTP Cache-Control extension (see RFC 5861). * stale_if_error Specifies the default number of seconds (the granularity is the second) during which the cache can serve a stale response when an error is encountered (default: 60). This setting is overridden by the stale-if-error HTTP Cache-Control extension (see RFC 5861).

$kernel	Symfony\Component\HttpKernel\HttpKernelInterface	An HttpKernelInterface instance
$store	Symfony\Component\HttpKernel\Cache\Store	A Store instance
$esi	Symfony\Component\HttpKernel\Cache\Esi	An Esi instance
$options	array	An array of options

fetch() 보호된 메소드

This methods is trigered when the cache missed or a reload is required.

protected fetch ( Request $request ) : Response
$request	Symfony\Component\HttpFoundation\Request	A Request instance
리턴	Symfony\Component\HttpFoundation\Response	A Response instance

forward() 보호된 메소드

Forwards the Request to the backend and returns the Response.

protected forward ( Request $request, boolean $catch = false, Response $entry = null ) : Response
$request	Symfony\Component\HttpFoundation\Request	A Request instance
$catch	boolean	Whether to catch exceptions or not
$entry	Symfony\Component\HttpFoundation\Response
리턴	Symfony\Component\HttpFoundation\Response	A Response instance

getLog() 공개 메소드

Returns a log message for the events of the last request processing.

public getLog ( ) : string
리턴	string	A log message

getRequest() 공개 메소드

Gets the Request instance associated with the master request.

public getRequest ( ) : Request
리턴	Symfony\Component\HttpFoundation\Request	A Request instance

getTraces() 공개 메소드

Returns an array of events that took place during processing of the last request.

public getTraces ( ) : array
리턴	array	An array of events

handle() 공개 메소드

public handle ( Request $request, $type = HttpKernelInterface::MASTER_REQUEST, $catch = true )
$request	Symfony\Component\HttpFoundation\Request

invalidate() 보호된 메소드

Invalidates non-safe methods (like POST, PUT, and DELETE).

protected invalidate ( Request $request ) : Response
$request	Symfony\Component\HttpFoundation\Request	A Request instance
리턴	Symfony\Component\HttpFoundation\Response	A Response instance

isFreshEnough() 보호된 메소드

Checks whether the cache entry is "fresh enough" to satisfy the Request.

protected isFreshEnough ( Request $request, Response $entry ) : boolean
$request	Symfony\Component\HttpFoundation\Request	A Request instance
$entry	Symfony\Component\HttpFoundation\Response	A Response instance
리턴	boolean	true if the cache entry if fresh enough, false otherwise

isPrivateRequest() 보호된 메소드

Checks if the Request includes authorization or other sensitive information that should cause the Response to be considered private by default.

protected isPrivateRequest ( Request $request ) : boolean
$request	Symfony\Component\HttpFoundation\Request	A Request instance
리턴	boolean	true if the Request is private, false otherwise

lock() 보호된 메소드

Locks a Request during the call to the backend.

protected lock ( Request $request, Response $entry ) : boolean
$request	Symfony\Component\HttpFoundation\Request	A Request instance
$entry	Symfony\Component\HttpFoundation\Response	A Response instance
리턴	boolean	true if the cache entry can be returned even if it is staled, false otherwise

lookup() 보호된 메소드

When a matching cache entry is found and is fresh, it uses it as the response without forwarding any request to the backend. When a matching cache entry is found but is stale, it attempts to "validate" the entry with the backend using conditional GET. When no matching cache entry is found, it triggers "miss" processing.

protected lookup ( Request $request ) : Response
$request	Symfony\Component\HttpFoundation\Request	A Request instance
리턴	Symfony\Component\HttpFoundation\Response	A Response instance

pass() 보호된 메소드

Forwards the Request to the backend without storing the Response in the cache.

$request	Symfony\Component\HttpFoundation\Request	A Request instance
리턴	Symfony\Component\HttpFoundation\Response	A Response instance

processResponseBody() 보호된 메소드

protected processResponseBody ( Request $request, Response $response )
$request	Symfony\Component\HttpFoundation\Request
$response	Symfony\Component\HttpFoundation\Response

record() 보호된 메소드

protected restoreResponseBody ( Response $response ) : Response
$response	Symfony\Component\HttpFoundation\Response	A Response instance
리턴	Symfony\Component\HttpFoundation\Response	A Response instance

store() 보호된 메소드

Writes the Response to the cache.

protected store ( Request $request, Response $response )
$request	Symfony\Component\HttpFoundation\Request	A Request instance
$response	Symfony\Component\HttpFoundation\Response	A Response instance

validate() 보호된 메소드

The original request is used as a template for a conditional GET request with the backend.

protected validate ( Request $request, Response $entry ) : Response
$request	Symfony\Component\HttpFoundation\Request	A Request instance
$entry	Symfony\Component\HttpFoundation\Response	A Response instance to validate
리턴	Symfony\Component\HttpFoundation\Response	A Response instance
