2. Select Object Storage Service (OBS) for Trigger Type, and set the trigger information, as shown in Figure 1.

   Select bucket input_bucket.

   For Events, select Post and Put.

   After the OBS trigger is created, when a file is uploaded or updated to bucket dew-bucket-input, an event is generated to trigger the function.
