Class CakeResponse

CakeResponse is responsible for managing the response text, status and headers of a HTTP response.

By default controllers will use this class to render their response. If you are going to use a custom response class it should subclass this object in order to ensure compatibility.

Checks whether a response has not been modified according to the 'If-None-Match' (Etags) and 'If-Modified-Since' (last modification date) request headers. If the response is detected to be not modified, it is marked as so accordingly so the client can be informed of that.

In order to mark a response as not modified, you need to set at least the Last-Modified etag response header before calling this method. Otherwise a comparison will not be possible.

corssource public

cors( CakeRequest $request , string|array $allowedDomains , string|array $allowedMethods array() , string|array $allowedHeaders array() )

Setup access for origin and methods on cross origin requests

This method allow multiple ways to setup the domains, see the examples

Full URI

e.g cors($request, 'http://www.cakephp.org');

URI with wildcard

e.g cors($request, 'http://*.cakephp.org');

Ignoring the requested protocol

e.g cors($request, 'www.cakephp.org');

Any URI

e.g cors($request, '*');

Whitelist of URIs

e.g cors($request, array('http://www.cakephp.org', '*.google.com', 'https://myproject.github.io'));

Parameters

CakeRequest $request: Request object
string|array $allowedDomains: List of allowed domains, see method description for more details
string|array $allowedMethods optional array(): List of HTTP verbs allowed
string|array $allowedHeaders optional array(): List of HTTP headers allowed

disableCachesource public

disableCache( )

Sets the correct headers to instruct the client to not cache the response

downloadsource public

download( string $filename )

Sets the correct headers to instruct the browser to download the response as a file.

Parameters

string $filename: the name of the file as the browser will download the response

etagsource public

etag( string $tag null , boolean $weak false )

Sets the response Etag, Etags are a strong indicative that a response can be cached by a HTTP client. A bad way of generating Etags is creating a hash of the response output, instead generate a unique hash of the unique components that identifies a request, such as a modification time, a resource Id, and anything else you consider it makes it unique.

Second parameter is used to instruct clients that the content has changed, but sematicallly, it can be used as the same thing. Think for instance of a page with a hit counter, two different page views are equivalent, but they differ by a few bytes. This leaves off to the Client the decision of using or not the cached page.

If no parameters are passed, current Etag header is returned.

Parameters

string $tag optional null: Tag to set.
boolean $weak optional false: whether the response is semantically the same as other with the same hash or not

Returns

string
string

expiressource public

expires( string|DateTime $time null )

Parameters

string|DateTime $time optional null: Valid time string or DateTime object.

Returns

string
string

filesource public

file( string $path , array $options array() )

If $_SERVER['HTTP_RANGE'] is set a slice of the file will be returned instead of the entire file.

Options keys

name: Alternate download name
download: If true sets download header and forces file to be downloaded rather than displayed in browser

Parameters

string $path: Path to file. If the path is not an absolute path that resolves to a file, APP will be prepended to the path.
array $options optional array(): Options See above.

getMimeTypesource public

getMimeType( string $alias )

Returns the mime type definition for an alias

String header

e.g header('WWW-Authenticate: Negotiate');

Array of string headers

e.g header(array('WWW-Authenticate: Negotiate', 'Content-type: application/pdf'));

Multiple calls for setting the same header name will have the same effect as setting the header once with the last value sent for it e.g header('WWW-Authenticate: Negotiate'); header('WWW-Authenticate: Not-Negotiate'); will have the same effect as only doing header('WWW-Authenticate: Not-Negotiate');

Parameters

string|array $header optional null: An array of header strings or a single header string - an associative array of "header name" => "header value" is also accepted - an array of string headers is also accepted

httpCodes( integer|array $code null )

Queries & sets valid HTTP response codes & messages.

Parameters

integer|array $code optional null: If $code is an integer, then the corresponding code/message is returned if it exists, null if it does not exist. If $code is an array, then the keys are used as codes and the values as messages to add to the default HTTP codes. The codes must be integers greater than 99 and less than 1000. Keep in mind that the HTTP specification outlines that status codes begin with a digit between 1 and 5, which defines the class of response the client is to expect. Example: httpCodes(404); // returns array(404 => 'Not Found') httpCodes(array( 381 => 'Unicorn Moved', 555 => 'Unexpected Minotaur' )); // sets these new values, and returns true httpCodes(array( 0 => 'Nothing Here', -1 => 'Reverse Infinity', 12345 => 'Universal Password', 'Hello' => 'World' )); // throws an exception due to invalid codes For more on HTTP status codes see: http://www.w3.org/Protocols/rfc2616/rfc2616-sec6.html#sec6.1
