list_messages Method
Gets messages from the queue.
Syntax
def list_messages(queue_id: str) -> None: ...
Remarks
This method retrieves messages from the queue specified by QueueId, and fires a on_message event for each message it receives. The messages may also be accessed using the property messages.
If visibility_timeout greater than -1 it is applied to the messages, otherwise the default timeout of the queue used. Only one message is retrieved by default; this behavior may be modified by changing max_messages.
Note: Unlike messages received from standard queues, messages received from FIFO queues can only be deleted within their visibility_timeout. Attempting to call delete_message for a message received from a FIFO queue after its visibility_timeout has expired will cause the server to return an error.
