Fill both blanks to define a Queue trigger function that listens to the 'tasks' queue and uses the correct parameter type.

Azure

    logging.info(f'Received message: {msg.[2]')

Drag options to blanks, or click blank then click option'

💡 Hint

Common Mistakes

Using incorrect parameter types or accessing wrong attributes.

The parameter type for a Queue trigger message is func.QueueMessage, and the message content is accessed via the content attribute.

Fill all three blanks to define an HTTP triggered Azure Function that reads a query parameter 'name' and returns a greeting.

Azure

def main(req: func.HttpRequest) -> func.HttpResponse:
    name = req.params.get('[1]')
    if not name:
        try:
            req_body = req.get_json()
        except ValueError:
            pass
        else:
            name = req_body.get('[2]')
    if name:
        return func.HttpResponse(f'Hello, [3]!')
    else:
        return func.HttpResponse('Please pass a name on the query string or in the request body.', status_code=400)

Drag options to blanks, or click blank then click option'

Common Mistakes

Using different keys for query and JSON, or wrong variable in greeting.

The query parameter and JSON key are both 'name', and the greeting uses the variable name.
