|
# Encrypted get from the namespace database file at the domain level. |
|
# This function retrieves a keyed item from a specific named database in the |
|
# domain directory. |
|
# |
|
# Parameters: |
|
# $cmd - Command request keyword (lti). |
|
# $tail - Tail of the command. This is a colon-separated list |
|
# consisting of the domain, coursenum, if for LTI- |
|
# enabled deep-linking to course content using |
|
# link protection configured within a course, |
|
# context (=deeplink) if for LTI-enabled deep-linking |
|
# to course content using LTI Provider settings |
|
# configured within a course's domain, the (escaped) |
|
# launch URL, the (escaped) method (typically POST), |
|
# and a frozen hash of the LTI launch parameters |
|
# from the LTI payload. |
|
# $client - File descriptor open on the client. |
|
# Returns: |
|
# 1 - Continue processing. |
|
# 0 - Exit. |
|
# Side effects: |
|
# The reply will contain an LTI itemID, if the signed LTI payload |
|
# could be verified using the consumer key and the shared secret |
|
# available for that key (for the itemID) for either the course or domain, |
|
# depending on values for cnum and context. The reply is encrypted before |
|
# being written to $client. |
