TriggerARN
TriggerARN format: acs:cdn:{RegionID}:{AccountID}:{Filter}.
- Filter indicates the resource and filter in the format of
{FilterName}/{FilterValue}. If you want to specify multiple values for FilterValue, separate the values with commas (,) and enclose them with braces ({}). - In this example, the LogFileCreated event supports a filter of which FilterName is set to domain. Function Compute can be triggered only by
example.comif Filter is set todomain/example.com. Function Compute can be triggered by multiple domains if Filter is set todomain/{example.com,aliyundoc.com}. - Separate filters with forward slashes (/). The forward slashes indicate the AND logic. Format:
acs:cdn:{RegionID}:{AccountID}:{Filter1}/{Filter2}/{Filter3}....
