CfnAuthorizer

class aws_cdk.aws_apigateway.CfnAuthorizer(scope, id, *, name, rest_api_id, type, authorizer_credentials=None, authorizer_result_ttl_in_seconds=None, authorizer_uri=None, auth_type=None, identity_source=None, identity_validation_expression=None, provider_arns=None)

Bases: aws_cdk.core.CfnResource

A CloudFormation AWS::ApiGateway::Authorizer.

The AWS::ApiGateway::Authorizer resource creates an authorization layer that API Gateway activates for methods that have authorization enabled. API Gateway activates the authorizer when a client calls those methods.

import aws_cdk.aws_apigateway as apigateway

cfn_authorizer = apigateway.CfnAuthorizer(self, "MyCfnAuthorizer",

    identity_validation_expression="identityValidationExpression",
    provider_arns=["providerArns"]
)

Create a new AWS::ApiGateway::Authorizer.

Parameters
  • scope (Construct) –

    • scope in which this resource is defined.

  • id (str) –

    • scoped id of the resource.

  • name (str) – The name of the authorizer.

  • rest_api_id (str) – The ID of the RestApi resource that API Gateway creates the authorizer in.

  • type (str) – The type of authorizer. Valid values include:. - TOKEN : A custom authorizer that uses a Lambda function. - COGNITO_USER_POOLS : An authorizer that uses Amazon Cognito user pools. - REQUEST : An authorizer that uses a Lambda function using incoming request parameters.

  • authorizer_credentials (Optional[str]) – The credentials that are required for the authorizer. To specify an IAM role that API Gateway assumes, specify the role’s Amazon Resource Name (ARN). To use resource-based permissions on the Lambda function, specify null.

  • authorizer_result_ttl_in_seconds (Union[int, float, None]) – The time-to-live (TTL) period, in seconds, that specifies how long API Gateway caches authorizer results. If you specify a value greater than 0, API Gateway caches the authorizer responses. By default, API Gateway sets this property to 300. The maximum value is 3600, or 1 hour.

  • authorizer_uri (Optional[str]) – The authorizer’s Uniform Resource Identifier (URI). If you specify TOKEN for the authorizer’s Type property, specify a Lambda function URI that has the form arn:aws:apigateway: *region* :lambda:path/ *path* . The path usually has the form /2015-03-31/functions/ LambdaFunctionARN /invocations.

  • auth_type (Optional[str]) – An optional customer-defined field that’s used in OpenApi imports and exports without functional impact.

  • identity_source (Optional[str]) – The source of the identity in an incoming request. If you specify TOKEN or COGNITO_USER_POOLS for the Type property, this property is required. Specify a header mapping expression using the form method.request.header. *name* , where name is the name of a custom authorization header that clients submit as part of their requests. If you specify REQUEST for the Type property, this property is required when authorization caching is enabled. Specify a comma-separated string of one or more mapping expressions of the specified request parameter using the form method.request.parameter. *name* . For supported parameter types, see Configure Lambda Authorizer Using the API Gateway Console in the API Gateway Developer Guide .

  • identity_validation_expression (Optional[str]) – A validation expression for the incoming identity. If you specify TOKEN for the authorizer’s Type property, specify a regular expression. API Gateway uses the expression to attempt to match the incoming client token, and proceeds if the token matches. If the token doesn’t match, API Gateway responds with a 401 (unauthorized request) error code.

  • provider_arns (Optional[Sequence[str]]) – A list of the Amazon Cognito user pool Amazon Resource Names (ARNs) to associate with this authorizer. Required if you specify COGNITO_USER_POOLS as the authorizer Type . For more information, see Use Amazon Cognito User Pools in the API Gateway Developer Guide .

Methods

add_deletion_override(path)

Syntactic sugar for addOverride(path, undefined).

Parameters

path (str) – The path of the value to delete.

Return type

None

add_depends_on(target)

Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.

This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.

Parameters

target (CfnResource) –

Return type

None

add_metadata(key, value)

Add a value to the CloudFormation Resource Metadata.

Parameters
  • key (str) –

  • value (Any) –

See

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html

Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.

Return type

None

add_override(path, value)

Adds an override to the synthesized CloudFormation resource.

To add a property override, either use addPropertyOverride or prefix path with “Properties.” (i.e. Properties.TopicName).

If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.

To include a literal . in the property name, prefix with a \. In most programming languages you will need to write this as "\\." because the \ itself will need to be escaped.

For example:

cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"])
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")

would add the overrides Example:

"Properties": {
   "GlobalSecondaryIndexes": [
     {
       "Projection": {
         "NonKeyAttributes": [ "myattribute" ]
         ...
       }
       ...
     },
     {
       "ProjectionType": "INCLUDE"
       ...
     },
   ]
   ...
}
Parameters
  • path (str) –

    • The path of the property, you can use dot notation to override values in complex types. Any intermdediate keys will be created as needed.

  • value (Any) –

    • The value. Could be primitive or complex.

Return type

None

add_property_deletion_override(property_path)

Adds an override that deletes the value of a property from the resource definition.

Parameters

property_path (str) – The path to the property.

Return type

None

add_property_override(property_path, value)

Adds an override to a resource property.

Syntactic sugar for addOverride("Properties.<...>", value).

Parameters
  • property_path (str) – The path of the property.

  • value (Any) – The value.

Return type

None

apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)

Sets the deletion policy of the resource based on the removal policy specified.

The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.

The resource can be deleted (RemovalPolicy.DESTROY), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN).

Parameters
  • policy (Optional[RemovalPolicy]) –

  • apply_to_update_replace_policy (Optional[bool]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: true

  • default (Optional[RemovalPolicy]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resoure, please consult that specific resource’s documentation.

Return type

None

get_att(attribute_name)

Returns a token for an runtime attribute of this resource.

Ideally, use generated attribute accessors (e.g. resource.arn), but this can be used for future compatibility in case there is no generated attribute.

Parameters

attribute_name (str) – The name of the attribute.

Return type

Reference

get_metadata(key)

Retrieve a value value from the CloudFormation Resource Metadata.

Parameters

key (str) –

See

https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html
