JsonResponse

Constructor.

Factory method for chainability.

Example:

return Response::create($body, 200)
    ->setSharedMaxAge(300);

Returns the Response as an HTTP string.

The string representation of the Response is the same as the one that will be sent to the client only if the prepare() method has been called before.

Clones the current Response instance.

Prepares the Response before it is sent to the client.

This method tweaks the Response to ensure that it is compliant with RFC 2616. Most of the changes are based on the Request that is "associated" with this Response.

Sends HTTP headers.

Sends content for the current web response.

Sends HTTP headers and content.

Sets the response content.

Valid types are strings, numbers, null, and objects that implement a __toString() method.

Gets the current response content.

Sets the HTTP protocol version (1.0 or 1.1).

Gets the HTTP protocol version.

Sets the response status code.

Retrieves the status code for the current web response.

Sets the response charset.

Retrieves the response charset.

Returns true if the response is worth caching under any circumstance.

Responses marked "private" with an explicit Cache-Control directive are considered uncacheable.

Responses with neither a freshness lifetime (Expires, max-age) nor cache validator (Last-Modified, ETag) are considered uncacheable.

Returns true if the response is "fresh".

Fresh responses may be served from cache without any interaction with the origin. A response is considered fresh when it includes a Cache-Control/max-age indicator or Expires header and the calculated age is less than the freshness lifetime.

Returns true if the response includes headers that can be used to validate the response with the origin server using a conditional GET request.

Marks the response as "private".

It makes the response ineligible for serving other clients.

Marks the response as "public".

It makes the response eligible for serving other clients.

Returns true if the response must be revalidated by caches.

This method indicates that the response must not be served stale by a cache in any circumstance without first revalidating with the origin. When present, the TTL of the response should not be overridden to be greater than the value provided by the origin.

Returns the Date header as a DateTime instance.

Sets the Date header.

Returns the age of the response.

Marks the response stale by setting the Age header to be equal to the maximum age of the response.

Returns the value of the Expires header as a DateTime instance.

Sets the Expires HTTP header with a DateTime instance.

Passing null as value will remove the header.

Returns the number of seconds after the time specified in the response's Date header when the response should no longer be considered fresh.

First, it checks for a s-maxage directive, then a max-age directive, and then it falls back on an expires header. It returns null when no maximum age can be established.

Sets the number of seconds after which the response should no longer be considered fresh.

This methods sets the Cache-Control max-age directive.

Sets the number of seconds after which the response should no longer be considered fresh by shared caches.

This methods sets the Cache-Control s-maxage directive.

Returns the response's time-to-live in seconds.

It returns null when no freshness information is present in the response.

When the responses TTL is <= 0, the response may not be served from cache without first revalidating with the origin.

Sets the response's time-to-live for shared caches.

This method adjusts the Cache-Control/s-maxage directive.

Sets the response's time-to-live for private/client caches.

This method adjusts the Cache-Control/max-age directive.

Returns the Last-Modified HTTP header as a DateTime instance.

Sets the Last-Modified HTTP header with a DateTime instance.

Passing null as value will remove the header.

Returns the literal value of the ETag HTTP header.

Sets the ETag value.

Sets the response's cache headers (validation and/or expiration).

Available options are: etag, lastmodified, maxage, s_maxage, private, and public.

Modifies the response so that it conforms to the rules defined for a 304 status code.

This sets the status, removes the body, and discards any headers that MUST NOT be included in 304 responses.

Returns true if the response includes a Vary header.

Returns an array of header names given in the Vary header.

Sets the Vary header.

Determines if the Response validators (ETag, Last-Modified) match a conditional value specified in the Request.

If the Response is not modified, it sets the status code to 304 and removes the actual content by calling the setNotModified() method.

Cleans or flushes output buffers up to target level.
