class Aws::APIGateway::Types::Method

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 Authorization: AWS4-HMAC-SHA256 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.

@return [String]

@!attribute [rw] authorization_type

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.
@return [String]

@!attribute [rw] authorizer_id

The identifier of an Authorizer to use on this method. The
`authorizationType` must be `CUSTOM`.
@return [String]

@!attribute [rw] api_key_required

A boolean flag specifying whether a valid ApiKey is required to
invoke this method.
@return [Boolean]

@!attribute [rw] request_validator_id

The identifier of a RequestValidator for request validation.
@return [String]

@!attribute [rw] operation_name

method in the `PetStore` example.
@return [String]

@!attribute [rw] request_parameters

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.
@return [Hash<String,Boolean>]

@!attribute [rw] request_models

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).

@!attribute [rw] method_responses

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

<div class="remarks" markdown="1">
The collection of method responses are encapsulated in a key-value
map, where the key is a response's HTTP status code and the value
is a MethodResponse resource that specifies the response returned to
the caller from the back end through the integration response.

@!attribute [rw] authorization_scopes

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.
