This loader is not compatible with all Blackboard courses. It is only compatible with courses that use the new Blackboard interface. To use this loader, you must have the BbRouter cookie. You can get this cookie by logging into the course and then copying the value of the BbRouter cookie from the browser's developer tools. Example: .. code-block:: python from langchain_community.document_loaders import BlackboardLoader loader = BlackboardLoader( blackboard_course_url="https://blackboard.example.com/webapps/blackboard/execute/announcement?method=search&context=course_entry&course_id=_123456_1", bbrouter="expires:12345...", ) documents = loader.load() TNFblackboard_course_urlbbrouterload_all_recursively basic_authcookiescontinue_on_failure show_progressct||| |dd|_n#t$rt dwxYw| ||j_|i}|d|i|jj|||_ | dS)aYInitialize with blackboard course url. The BbRouter cookie is required for most blackboard courses. Args: blackboard_course_url: Blackboard course url. bbrouter: BbRouter cookie. load_all_recursively: If True, load all documents recursively. basic_auth: Basic auth credentials. cookies: Cookies. continue_on_failure: whether to continue loading the sitemap if an error occurs loading a url, emitting a warning instead of raising an exception. Setting this to True makes the loader more robust, but also may result in missing data. Default: False show_progress: whether to show a progress bar while loading. Default: True Raises: ValueError: If blackboard course url is invalid. ) web_pathsrrz/webapps/blackboardrzpInvalid blackboard course url.
