问题:AWS AppFlow可以在不同应用程序之间的任何地方安全地轻松移动数据,其中包括Slack频道。但是,当它在Slack频道中检测到新数据时,很可能会导致与之前加载的数据相同的数据被再次加载。因此,以下是解决此问题的代码示例:
client = boto3.client('appflow')
response = client.list_flows()
for result in response['flows']:
if result['flowName'] == 'MySlackFlow':
response = client.describe_flow(
flowName=result['flowName'],
flowArn=result['flowArn']
)
for trigger in response['flow']['triggers']:
if trigger['triggerType'] == 'Poll' and trigger['sourceProperties']['object'] == 'Posts':
trigger['sourceProperties']['offset'] = 'LAST_POST'
response = client.update_flow(flowArn=result['flowArn'], flowName=result['flowName'], flowDefinition=response['flow'])
此代码将更新AWS AppFlow中的Slack频道轮询触发器,并将其设置为如果新数据可用,则从上一个“LAST_POST”偏移量处轮询。这确保每次轮询时都会更新数据。
