Class SecurityComponent
The Security Component creates an easy way to integrate tighter security in your application. It provides methods for various tasks like:
- Restricting which HTTP methods your application accepts.
- Form tampering protection
- Requiring that SSL be used.
- Limiting cross controller communication.

Returns
Methods inherited from Cake\Controller\Component
__construct() public ¶
__construct( Cake\Controller\ComponentRegistry $registry , array $config [] )

Parameters
-
Cake\Controller\ComponentRegistry$registry - A ComponentRegistry this component can use to lazy load its components
- array $config optional []
- Array of configuration settings.
__debugInfo() public ¶
__debugInfo( )
Returns an array that can be used to describe the internal state of this object.
Returns
__get() public ¶
__get( string $name )
Magic method for lazy loading $components.
Parameters
- string $name
- Name of component to get.
Returns
A Component object or null.
initialize() public ¶
initialize( array $config )
Constructor hook method.
Implement this method to avoid having to overwrite the constructor and call parent.
Parameters
- array $config
- The configuration settings provided to this component.
Methods used from Cake\Core\InstanceConfigTrait
_configDelete() protected ¶
_configDelete( string $key )
Delete a single config key
Parameters
- string $key
- Key to delete.
Throws
_configRead() protected ¶
_configRead( string|null $key )
Read a config variable
Parameters
- string|null $key
- Key to read.
Returns
_configWrite() protected ¶
_configWrite( string|array $key , mixed $value , boolean|string $merge false )
Write a config variable
Parameters
- string|array $key
- Key to write to.
- 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
config() public ¶
config( string|array|null $key null , mixed|null $value null , boolean $merge true )
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
Config value being read, or the object itself on write operations.
Throws
configShallow() 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->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 $key

$_defaultConfig ¶
Default config
blackHoleCallback- The controller method that will be called if this request is black-hole'd.requireSecure- List of actions that require an SSL-secured connection.requireAuth- List of actions that require a valid authentication key.allowedControllers- Controllers from which actions of the current controller are allowed to receive requests.allowedActions- Actions from which actions of the current controller are allowed to receive requests.unlockedFields- Form fields to exclude from POST validation. Fields can be unlocked either in the Component, or with FormHelper::unlockField(). Fields that have been unlocked are not required to be part of the POST and hidden unlocked fields do not have their values checked.unlockedActions- Actions to exclude from POST validation checks. Other checks like requireAuth(), requireSecure() etc. will still be applied.validatePost- Whether to validate POST data. Set to false to disable for data coming from 3rd party services, etc.
