How to use the Simple Web Services Framework:

Post to handler.php a field called service_request.

This field is JSON text containing:

• Numeric user ID
• Rolling session  key
• Service requested
• Action to take
• Any additional values required by the service

The return value will be a JSON string containing:

• Numeric user ID
• New session key value
• Results from the user exit function

Configuration:

• config.php contains the URL to the handler.php file and the DB connection information.
• Define a service
• Define an action
• Define a role
• Create a link from a service and action combination to a function name
• Add that service and action to a role
• Add the role to the user

Programming:

• In the application.php file, create a function corresponding to the configuration above.
• The function will receive an associative array with all of the contents of the JSON request.
• The function must return an associative array of the values to be passed back.
• User ID and session key values will be handled automatically, and do not need to be addressed.

Features:

• Role based security
• JSON in, JSON out
• Rolling key to prevent session hijacking without a state requirement
• Simple HTTP/S requests to allow access from any platform
• Delivered example call from PHP
