Define a function

Define a function by using Python

1. Log on to the Function Compute console.
2. In the top navigation bar, select a region.
3. In the left-side navigation pane, click Service/Function.
4. Locate the target function in the target service and click the function name.
   
5. Click Code tag, and write code in the code editor.
   In the following example, Python is used to define the function.

   import json
   import logging
   
   logger = logging.getLogger()
   
   def handler(event, context):
       logger.info('event: %s', event)
   
       evt = json.loads(event)
       triggerName = evt["triggerName"]
       triggerTime = evt["triggerTime"]
       message = evt["payload"]
       creds = context.credentials
       logger.info('access_key_id: %s', creds.access_key_id)
       logger.info("message = %s", message)                        

Event format

A time trigger triggers a function by parsing the following event format:

{
    "triggerTime":"2018-02-09T05:49:00Z",
    "triggerName":"my_trigger",
    "payload":"awesome-fc"
}
