Method class

Represents a client-facing interface by which the client calls the API to access back-end resources. A Method resource is integrated with an Integration resource. Both consist of a request and one or more responses. The method request takes the client input that is passed to the back end through the integration request. A method response returns the output from the back end to the client through an integration response. A method request is embodied in a Method resource, whereas an integration request is embodied in an Integration resource. On the other hand, a method response is represented by a MethodResponse resource, whereas an integration response is represented by an IntegrationResponse resource.

Example: Retrive the GET method on a specified resource

Request

The following example request retrieves the information about the GET method on an API resource (3kzxbg5sa2) of an API (fugvjdxtri).

GET /restapis/fugvjdxtri/resources/3kzxbg5sa2/methods/GET
HTTP/1.1 Content-Type: application/json Host:
apigateway.us-east-1.amazonaws.com X-Amz-Date: 20160603T210259Z

Credential={access_key_ID}/20160603/us-east-1/apigateway/aws4_request,
SignedHeaders=content-type;host;x-amz-date,
Signature={sig4_hash}

Response

The successful response returns a 200 OK status code and a payload similar to the following:

In the example above, the response template for the 200 OK response maps the JSON output from the ListStreams action in the back end to an XML output. The mapping template is URL-encoded as %3CkinesisStreams%3E%23foreach(%24stream%20in%20%24input.path(%27%24.StreamNames%27))%3Cstream%3E%3Cname%3E%24stream%3C%2Fname%3E%3C%2Fstream%3E%23end%3C%2FkinesisStreams%3E and the output is decoded using the $util.urlDecode() helper function.

Constructors

Properties

apiKeyRequired → bool?

A boolean flag specifying whether a valid ApiKey is required to invoke this method.

final

authorizationScopes → List<String>?

A list of authorization scopes configured on the method. The scopes are used with a COGNITO_USER_POOLS authorizer to authorize the method invocation. The authorization works by matching the method scopes against the scopes parsed from the access token in the incoming request. The method invocation is authorized if any method scopes matches a claimed scope in the access token. Otherwise, the invocation is not authorized. When the method scope is configured, the client must provide an access token instead of an identity token for authorization purposes.

final

authorizationType → String?

The method's authorization type. Valid values are NONE for open access, AWS_IAM for using AWS IAM permissions, CUSTOM for using a custom authorizer, or COGNITO_USER_POOLS for using a Cognito user pool.

final

authorizerId → String?

The identifier of an Authorizer to use on this method. The authorizationType must be CUSTOM.

final

hashCode → int

The hash code for this object.

no setter, inherited

httpMethod → String?

The method's HTTP verb.

final

methodIntegration → Integration?

Gets the method's integration responsible for passing the client-submitted request to the back end and performing necessary transformations to make the request compliant with the back end.

final

methodResponses → Map<String, MethodResponse>?

Gets a method response associated with a given HTTP status code.

final

operationName → String?

A human-friendly operation identifier for the method. For example, you can assign the operationName of ListPets for the GET /pets method in the PetStore example.

final

requestModels → Map<String, String>?

A key-value map specifying data schemas, represented by Model resources, (as the mapped value) of the request payloads of given content types (as the mapping key).

final

requestParameters → Map<String, bool>?

A key-value map defining required or optional method request parameters that can be accepted by API Gateway. A key is a method request parameter name matching the pattern of method.request.{location}.{name}, where location is querystring, path, or header and name is a valid and unique parameter name. The value associated with the key is a Boolean flag indicating whether the parameter is required (true) or optional (false). The method request parameter names defined here are available in Integration to be mapped to integration request parameters or templates.

final

requestValidatorId → String?

The identifier of a RequestValidator for request validation.

final

runtimeType → Type

A representation of the runtime type of the object.

no setter, inherited

Methods

noSuchMethod(Invocation invocation) → dynamic

Invoked when a nonexistent method or property is accessed.

toString() → String

A string representation of this object.

Operators

operator ==(Object other) → bool

The equality operator.
