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.com if Filter is set to domain/example.com. Function Compute can be triggered by multiple domains if Filter is set to domain/{example.com,aliyun.com}.
  • Separate filters with forward slashes (/). Set the logical operator among filters to AND. Format: acs:cdn:{RegionID}:{AccountID}:{Filter1}/{Filter2}/{Filter3}....
