TokenAuthorizer

class aws_cdk.aws_apigateway.TokenAuthorizer(scope, id, *, identity_source=None, validation_regex=None, assume_role=None, authorizer_name=None, handler, results_cache_ttl=None)

Bases: aws_cdk.aws_apigateway.Authorizer

Token based lambda authorizer that recognizes the caller’s identity as a bearer token, such as a JSON Web Token (JWT) or an OAuth token.

Based on the token, authorization is performed by a lambda function.

Resource

AWS::ApiGateway::Authorizer

Example:

# auth_fn is of type Function
# books is of type Resource


auth = apigateway.TokenAuthorizer(self, "booksAuthorizer",
    handler=auth_fn
)

books.add_method("GET", apigateway.HttpIntegration("http://amazon.com"),
    authorizer=auth
)
Parameters

  • scope (Construct) –

  • id (str) –

  • identity_source (Optional[str]) – The request header mapping expression for the bearer token. This is typically passed as part of the header, in which case this should be method.request.header.Authorizer where Authorizer is the header containing the bearer token. Default: IdentitySource.header('Authorization')

  • validation_regex (Optional[str]) – An optional regex to be matched against the authorization token. When matched the authorizer lambda is invoked, otherwise a 401 Unauthorized is returned to the client. Default: - no regex filter will be applied.

  • assume_role (Optional[IRole]) – An optional IAM role for APIGateway to assume before calling the Lambda-based authorizer. The IAM role must be assumable by ‘apigateway.amazonaws.com’. Default: - A resource policy is added to the Lambda function allowing apigateway.amazonaws.com to invoke the function.

  • authorizer_name (Optional[str]) – An optional human friendly name for the authorizer. Note that, this is not the primary identifier of the authorizer. Default: - the unique construcrt ID

  • handler (IFunction) – The handler for the authorizer lambda function. The handler must follow a very specific protocol on the input it receives and the output it needs to produce. API Gateway has documented the handler’s input specification {@link https://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-lambda-authorizer-input.html | here} and output specification {@link https://docs.aws.amazon.com/apigateway/latest/developerguide/api-gateway-lambda-authorizer-output.html | here}.

  • results_cache_ttl (Optional[Duration]) – How long APIGateway should cache the results. Max 1 hour. Disable caching by setting this to 0. Default: Duration.minutes(5)

Methods

apply_removal_policy(policy)

Apply the given removal policy to this resource.

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 (RemovalPolicy) –

Return type

None

to_string()

Returns a string representation of this construct.

Return type

str

Attributes

authorization_type

The authorization type of this authorizer.

Return type

Optional[AuthorizationType]

authorizer_arn

The ARN of the authorizer to be used in permission policies, such as IAM and resource-based grants.

Return type

str

authorizer_id

The id of the authorizer.

Return type

str

env

The environment this resource belongs to.

For resources that are created and managed by the CDK (generally, those created by creating new class instances like Role, Bucket, etc.), this is always the same as the environment of the stack they belong to; however, for imported resources (those obtained from static methods like fromRoleArn, fromBucketName, etc.), that might be different than the stack they were imported into.

Return type

ResourceEnvironment

node

The construct tree node associated with this construct.

Return type

ConstructNode

stack

The stack in which this resource is defined.
