CfnUrlProps

class aws_cdk.aws_lambda.CfnUrlProps(*, auth_type, target_function_arn, cors=None, invoke_mode=None, qualifier=None)

Bases: object

Properties for defining a CfnUrl.

Parameters:
  • auth_type (str) – The type of authentication that your function URL uses. Set to AWS_IAM if you want to restrict access to authenticated users only. Set to NONE if you want to bypass IAM authentication to create a public endpoint. For more information, see Security and auth model for Lambda function URLs .

  • target_function_arn (str) – The name of the Lambda function. Name formats - Function name - my-function . - Function ARN - arn:aws:lambda:us-west-2:123456789012:function:my-function . - Partial ARN - 123456789012:function:my-function . The length constraint applies only to the full ARN. If you specify only the function name, it is limited to 64 characters in length.

  • cors (Union[IResolvable, CorsProperty, Dict[str, Any], None]) – The Cross-Origin Resource Sharing (CORS) settings for your function URL.

  • invoke_mode (Optional[str]) – Use one of the following options:. - BUFFERED – This is the default option. Lambda invokes your function using the Invoke API operation. Invocation results are available when the payload is complete. The maximum payload size is 6 MB. - RESPONSE_STREAM – Your function streams payload results as they become available. Lambda invokes your function using the InvokeWithResponseStream API operation. The maximum response payload size is 20 MB, however, you can request a quota increase .

  • qualifier (Optional[str]) – The alias name.
