Some major changes have been made to handle this new feature :
- LSsession now have a flag about API mode. The displayTemplate() and
displayAjaxReturn() methods have been adjust to correctly handle this
mode.
- LSauth system have been adjust to handle a custom API mode :
- LSauthMethod can support or not this mode : the $api_mode_supported
permit to defined if supported (default, false). Currently, only
HTTP (default in API mode) and annonymous mode support it.
- An api_access parameter permit to configure witch type of user
LSobject types could use the API. This flag must be set to True to
allow a type of LSobject (default: False). In a same way, a
web_access parameter now permit to disable Web access for some
types of users (but this parameter is optional and its default value
is True).
- The HTTP method is the privileged first method for API mode. In this
mode, if auth data aren't present in environment, it will request it
by triggered a 403 HTTP error. Realm can be configured with new
LSAUTHMETHOD_HTTP_API_REALM constant.
- The LStemplate system handle API mode to correctly react on errors: it
return a JSON answer instead of HTML page. Error pages also now return
adjusted HTTP code (404 or 500).
- The LSurl system have been adjust to handle API mode :
- On declaring handlers, we could now specify if it's an API view with
new $api_mode paremeter of add_handler() method
- The LSurlRequest object have a new attribute to check if it's an API
request
- The error_404() method handle the API mode to return JSON answer.
Furthermore, if no handlers matched with the requested URL, API mode
is automatically enabled if the requested URL starts with 'api/'.
- LSform implement it own API mode flag and a new submited flag that
be toggle via the new setSubmited() method. Some major changes also
occured on LSformElement classes to specifically handle API
input/output for each types of attributes:
- a new getApiValue() method permit to retrieve the API value of the
attribute (on show API view)
- the getPostData() method now have to correctly handle API input for
the attribute (on create/modify API views). A programmatic way have
been adopted for each types of attributes.
- The LSimport and LScli create/modify commands also evolved to enable
API mode of the LSform. This permit to take advantage of the new
capability of LSform/LSformElement to handle input values with a
programmatic way.
- New routes have been add to handle API views. All this new routes
start with 'api/1.0/' and use the same URL schema as the web UI. The
API currently permit to search/show/add/modify/remove LSobjects and
manages their relations.
