Class CsrfComponent
Provides CSRF protection & validation.
This component adds a CSRF token to a cookie. The cookie value is compared to request data, or the X-CSRF-Token header on each PATCH, POST, PUT, or DELETE request.
If the request data is missing or does not match the cookie data, an InvalidCsrfTokenException will be raised.
This component integrates with the FormHelper automatically and when used together your forms will have CSRF tokens automatically added when $this->Form->create(...)
is used in a view.

Method Summary
- Set the cookie in the response.
- Validate the request data against the cookie token.
- Events supported by this component.
- Startup callback.
Method Detail
_setCookie()source protected deprecated
_setCookie( Cake\Http\ServerRequest $request , Cake\Http\Response $response )
Set the cookie in the response.
Also sets the request->params['_csrfToken'] so the newly minted token is available in the request data.
Parameters
-
Cake\Http\ServerRequest
$request
- The request object.
-
Cake\Http\Response
$response
- The response object.
Returns
arrayAn array of the modified request, response.
_validateToken()source protected deprecated
_validateToken( Cake\Http\ServerRequest $request )
Validate the request data against the cookie token.
Parameters
-
Cake\Http\ServerRequest
$request
- The request to validate against.
Throws
Cake\Http\Exception\InvalidCsrfTokenException
when the CSRF token is invalid or missing.
implementedEvents()source public deprecated
implementedEvents( )
Events supported by this component.
Returns
arrayOverrides
Cake\Controller\Component::implementedEvents()
startup()source public deprecated
startup( Cake\Event\Event $event )
Startup callback.
Validates the CSRF token for POST data. If the request is a GET request, and the cookie value is absent a cookie will be set.
Once a cookie is set it will be copied into request->getParam('_csrfToken') so that application and framework code can easily access the csrf token.
RequestAction requests do not get checked, nor will they set a cookie should it be missing.
Parameters
-
Cake\Event\Event
$event
- Event instance.

initialize()source public
initialize( array $config )
Constructor hook method.
Implement this method to avoid having to overwrite the constructor and call parent.
Parameters

_configDelete()source protected
_configDelete( string $key )
Deletes a single config key.
Parameters
- string
$key
- Key to delete.
Throws

- Key to read.
Returns
mixed_configWrite()source protected
_configWrite( string|array $key , mixed $value , boolean|string $merge = false )
Writes a config key.

- mixed
$value
- Value to write.
- boolean|string
$merge
optional false True to merge recursively, 'shallow' for simple merge, false to overwrite, defaults to false.
Throws

if attempting to clobber existing config
config()source public deprecated
config( string|array|null $key = null , mixed|null $value = null , boolean $merge = true )
Gets/Sets the config.
Usage
Reading the whole config:
$this->config();
Reading a specific value:
$this->config('key');
Reading a nested value:
$this->config('some.nested.key');
Setting a specific value:
$this->config('key', $value);
Setting a nested value:
$this->config('some.nested.key', $value);
Updating multiple config settings at the same time:
$this->config(['one' => 'value', 'another' => 'value']);
Parameters
- string|array|null
$key
optional null - The key to get/set, or a complete array of configs.
- mixed|null
$value
optional null - The value to set.
- boolean
$merge
optional true - Whether to recursively merge or overwrite existing config, defaults to true.
Returns
mixedConfig value being read, or the object itself on write operations.
Throws
Cake\Core\Exception\Exception
When trying to set a key that is invalid.
configShallow()source public
configShallow( string|array $key , mixed|null $value = null )
Merge provided config with existing config. Unlike config()
which does a recursive merge for nested keys, this method does a simple merge.
Setting a specific value:
$this->configShallow('key', $value);
Setting a nested value:
$this->configShallow('some.nested.key', $value);
Updating multiple config settings at the same time:
$this->configShallow(['one' => 'value', 'another' => 'value']);

getConfig()source public
getConfig( string|null $key = null , mixed $default = null )
