Class: service_base - X-Ref
The mod_lti\local\ltiservice\service_base class.__construct() X-Ref |
Class constructor. |
get_id() X-Ref |
Get the service ID. return: string |
get_component_id() X-Ref |
Get the service compoent ID. return: string |
get_name() X-Ref |
Get the service name. return: string |
is_unsigned() X-Ref |
Get whether the service requests need to be signed. return: boolean |
get_tool_proxy() X-Ref |
Get the tool proxy object. return: stdClass |
set_tool_proxy($toolproxy) X-Ref |
Set the tool proxy object. param: object $toolproxy The tool proxy for this service request |
get_type() X-Ref |
Get the type object. return: stdClass |
set_type($type) X-Ref |
Set the LTI type object. param: object $type The LTI type for this service request |
get_typeconfig() X-Ref |
Get the type config array. return: array|null |
set_typeconfig($typeconfig) X-Ref |
Set the LTI type config object. param: array $typeconfig The LTI type config for this service request |
get_permitted_scopes() X-Ref |
Get the scope(s) permitted for this service in the context of a particular tool type. A null value indicates that no scopes are required to access the service. return: array|null |
get_scopes() X-Ref |
Get the scope(s) permitted for this service. A null value indicates that no scopes are required to access the service. return: array|null |
get_configuration_options(&$mform) X-Ref |
Returns the configuration options for this service. param: \MoodleQuickForm $mform Moodle quickform object definition |
instance_added(object $lti) X-Ref |
Called when a new LTI Instance is added. param: object $lti LTI Instance. |
instance_updated(object $lti) X-Ref |
Called when a new LTI Instance is updated. param: object $lti LTI Instance. |
override_endpoint(string $messagetype, string $targetlinkuri,?string $customstr, int $courseid, ?object $lti = null) X-Ref |
Called when the launch data is created, offering a possibility to alter the target link URI. param: string $messagetype message type for this launch param: string $targetlinkuri current target link uri param: null|string $customstr concatenated list of custom parameters param: int $courseid param: null|object $lti LTI Instance. return: array containing the target link URL and the custom params string to use. |
instance_deleted(int $id) X-Ref |
Called when a new LTI Instance is deleted. param: int $id LTI Instance. |
set_instance_form_values(object $defaultvalues) X-Ref |
Set the form data when displaying the LTI Instance form. param: object $defaultvalues Default form values. |
get_configuration_parameter_names() X-Ref |
Return an array with the names of the parameters that the service will be saving in the configuration return: array Names list of the parameters that the service will be saving in the configuration |
is_used_in_context($typeid, $courseid) X-Ref |
Default implementation will check for the existence of at least one mod_lti entry for that tool and context. It may be overridden if other inferences can be done. Ideally a Site Tool should be explicitly engaged with a course, the check on the presence of a link is a proxy to infer a Site Tool engagement until an explicit Site Tool - Course relationship exists. param: int $typeid The tool lti type id. param: int $courseid The course id. return: bool returns True if tool is used in context, false otherwise. |
is_allowed_in_context($typeid, $courseid) X-Ref |
Checks if there is a site tool or a course tool for this site. param: int $typeid The tool lti type id. param: int $courseid The course id. return: bool returns True if tool is allowed in context, false otherwise. |
get_launch_parameters($messagetype, $courseid, $userid, $typeid, $modlti = null) X-Ref |
Return an array of key/values to add to the launch parameters. param: string $messagetype 'basic-lti-launch-request' or 'ContentItemSelectionRequest'. param: string $courseid The course id. param: string $userid The user id. param: string $typeid The tool lti type id. param: string $modlti The id of the lti activity. return: array Key/value pairs to add as launch parameters. |
get_jwt_claim_mappings() X-Ref |
Return an array of key/claim mapping allowing LTI 1.1 custom parameters to be transformed to LTI 1.3 claims. return: array Key/value pairs of params to claim mapping. |
get_service_path() X-Ref |
Get the path for service requests. return: string |
parse_value($value) X-Ref |
Parse a string for custom substitution parameter variables supported by this service's resources. param: string $value Value to be parsed return: string |
check_tool($typeid, $body = null, $scopes = null) X-Ref |
Check that the request has been properly signed and is permitted. param: string $typeid LTI type ID param: string $body Request body (null if none) param: string[] $scopes Array of required scope(s) for incoming request return: boolean |
check_tool_proxy($toolproxyguid, $body = null) X-Ref |
Check that the request has been properly signed. param: string $toolproxyguid Tool Proxy GUID param: string $body Request body (null if none) return: boolean |
check_type($typeid, $courseid, $body = null) X-Ref |
Check that the request has been properly signed. param: int $typeid The tool id param: int $courseid The course we are at param: string $body Request body (null if none) return: bool |
check_signature($consumerkey, $secret, $body) X-Ref |
Check the request signature. param: string $consumerkey Consumer key param: string $secret Shared secret param: string $body Request body return: boolean |
