Fusio

API

Fusio provides specific variables in every PHP-Action which can be used to produce a response. This API describes all available variables and can be used as a reference to develop new actions.

Objects
Name Description
$connector Through the connector it is possible to access configured connection objects. A connection is i.e. a MYSQL connection which can be configured at the admin panel. Inside an action it is possible to access this connection through this class. Which objects is returned depends on the connection type i.e. the MYSQL connection returns a Doctrine DBAL Connection instance and the HTTP connection returns a Guzzle instance. There are already many adapters available which allow many different kind of services i.e. ElasticSearch, MongoDB, AMQP, etc.
$request Represents an incoming HTTP request. This object can be used to access all values from an incoming request
$response The response factory MUST be used to create a response for an action. It is a factory method which returns a specific response object. Please always use this factory since this gives us the freedom to change the response implementation
$processor The processor can be used to invoke another action. Normally an action should only contain simple logic but in some cases you may want to invoke an existing action
$dispatcher The dispatcher can be used to trigger specific events. A consumer can subscribe to such events and they will receive a HTTP POST call to the defined endpoint in case you dispatch an event. The call happens in the background through a cronjob so the dispatch operation is not expensive
$logger Describes a logger instance. The message MUST be a string or object implementing __toString(). The message MAY contain placeholders in the form: {foo} where foo will be replaced by the context data in key "foo". The context array can contain arbitrary data. The only assumption that can be made by implementors is that if an Exception instance is given to produce a stack trace, it MUST be in a key named "exception". See https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-3-logger-interface.md for the full interface specification.
