get-method

Description

Describe an existing Method resource.

See also: AWS API Documentation

See ‘aws help’ for descriptions of global parameters.

Synopsis

  get-method
--rest-api-id <value>
--resource-id <value>
--http-method <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]

Options

--rest-api-id (string)

[Required] The string identifier of the associated RestApi .

--resource-id (string)

[Required] The Resource identifier for the Method resource.

--http-method (string)

[Required] Specifies the method request’s HTTP method type.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

Output

httpMethod -> (string)

The method’s HTTP verb.

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.

authorizerId -> (string)

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

apiKeyRequired -> (boolean)

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

requestValidatorId -> (string)

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.

requestParameters -> (map)

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.

key -> (string)

value -> (boolean)

requestModels -> (map)

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).

key -> (string)

value -> (string)

methodResponses -> (map)

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

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.

Example: Get a 200 OK response of a GET method Request

Method , IntegrationResponse , Integration Creating an API

statusCode -> (string)

The method response’s status code.

responseParameters -> (map)

A key-value map specifying required or optional response parameters that API Gateway can send back to the caller. A key defines a method response header and the value specifies whether the associated method response header is required or not. The expression of the key must match the pattern method.response.header.{name} , where name is a valid and unique header name. API Gateway passes certain integration response data to the method response headers specified here according to the mapping you prescribe in the API’s IntegrationResponse . The integration response data that can be mapped include an integration response header expressed in integration.response.header.{name} , a static value enclosed within a pair of single quotes (e.g., 'application/json' ), or a JSON expression from the back-end response payload in the form of integration.response.body.{JSON-expression} , where JSON-expression is a valid JSON expression without the $ prefix.)

key -> (string)

value -> (boolean)

responseModels -> (map)

Specifies the Model resources used for the response’s content-type. Response models are represented as a key/value map, with a content-type as the key and a Model name as the value.

key -> (string)

value -> (string)

methodIntegration -> (structure)

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.

Example: Request

GET /restapis/uojnr9hd57/resources/0cjtch/methods/GET/integration HTTP/1.1 Content-Type: application/json Host: apigateway.us-east-1.amazonaws.com Content-Length: 117 X-Amz-Date: 20160613T213210Z Authorization: AWS4-HMAC-SHA256 Credential={access_key_ID}/20160613/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:

AWS CLI

type -> (string)

Specifies an API method integration type. The valid value is one of the following:

• AWS : for integrating the API method request with an AWS service action, including the Lambda function-invoking action. With the Lambda function-invoking action, this is referred to as the Lambda custom integration. With any other AWS service action, this is known as AWS integration.

• AWS_PROXY : for integrating the API method request with the Lambda function-invoking action with the client request passed through as-is. This integration is also referred to as the Lambda proxy integration.

• HTTP : for integrating the API method request with an HTTP endpoint, including a private HTTP endpoint within a VPC. This integration is also referred to as the HTTP custom integration.

• HTTP_PROXY : for integrating the API method request with an HTTP endpoint, including a private HTTP endpoint within a VPC, with the client request passed through as-is. This is also referred to as the HTTP proxy integration.

• MOCK : for integrating the API method request with API Gateway as a “loop-back” endpoint without invoking any backend.

For the HTTP and HTTP proxy integrations, each integration can specify a protocol (http/https ), port and path. Standard 80 and 443 ports are supported as well as custom ports above 1024. An HTTP or HTTP proxy integration with a connectionType of VPC_LINK is referred to as a private integration and uses a VpcLink to connect API Gateway to a network load balancer of a VPC.

httpMethod -> (string)

Specifies the integration’s HTTP method type.

uri -> (string)

Specifies Uniform Resource Identifier (URI) of the integration endpoint.

• For HTTP or HTTP_PROXY integrations, the URI must be a fully formed, encoded HTTP(S) URL according to the RFC-3986 specification , for either standard integration, where connectionType is not VPC_LINK , or private integration, where connectionType is VPC_LINK . For a private HTTP integration, the URI is not used for routing.

• For AWS or AWS_PROXY integrations, the URI is of the form arn:aws:apigateway:{region}:{subdomain.service|service}:path|action/{service_api} . Here, {Region} is the API Gateway region (e.g., us-east-1 ); {service} is the name of the integrated AWS service (e.g., s3 ); and {subdomain} is a designated subdomain supported by certain AWS service for fast host-name lookup. action can be used for an AWS service action-based API, using an Action={name}&{p1}={v1}&p2={v2}... query string. The ensuing {service_api} refers to a supported action {name} plus any required input parameters. Alternatively, path can be used for an AWS service path-based API. The ensuing service_api refers to the path to an AWS service resource, including the region of the integrated AWS service, if applicable. For example, for integration with the S3 API of `GetObject <https://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectGET.html>`__ , the uri can be either arn:aws:apigateway:us-west-2:s3:action/GetObject&Bucket={bucket}&Key={key} or arn:aws:apigateway:us-west-2:s3:path/{bucket}/{key}

connectionType -> (string)

The type of the network connection to the integration endpoint. The valid value is INTERNET for connections through the public routable internet or VPC_LINK for private connections between API Gateway and a network load balancer in a VPC. The default value is INTERNET .

connectionId -> (string)

The (`id <https://docs.aws.amazon.com/apigateway/api-reference/resource/vpc-link/#id>`__ ) of the VpcLink used for the integration when connectionType=VPC_LINK and undefined, otherwise.

credentials -> (string)

Specifies the credentials required for the integration, if any. For AWS integrations, three options are available. To specify an IAM Role for API Gateway to assume, use the role’s Amazon Resource Name (ARN). To require that the caller’s identity be passed through from the request, specify the string arn:aws:iam::\*:user/\* . To use resource-based permissions on supported AWS services, specify null.

requestParameters -> (map)

A key-value map specifying request parameters that are passed from the method request to the back end. The key is an integration request parameter name and the associated value is a method request parameter value or static value that must be enclosed within single quotes and pre-encoded as required by the back end. The method request parameter value must match the pattern of method.request.{location}.{name} , where location is querystring , path , or header and name must be a valid and unique method request parameter name.

key -> (string)

value -> (string)

requestTemplates -> (map)

Represents a map of Velocity templates that are applied on the request payload based on the value of the Content-Type header sent by the client. The content type value is the key in this map, and the template (as a String) is the value.

key -> (string)

value -> (string)

passthroughBehavior -> (string)

Specifies how the method request body of an unmapped content type will be passed through the integration request to the back end without transformation. A content type is unmapped if no mapping template is defined in the integration or the content type does not match any of the mapped content types, as specified in requestTemplates . The valid value is one of the following:

• WHEN_NO_MATCH : passes the method request body through the integration request to the back end without transformation when the method request content type does not match any content type associated with the mapping templates defined in the integration request.

• WHEN_NO_TEMPLATES : passes the method request body through the integration request to the back end without transformation when no mapping template is defined in the integration request. If a template is defined when this option is selected, the method request of an unmapped content-type will be rejected with an HTTP 415 Unsupported Media Type response.

• NEVER : rejects the method request with an HTTP 415 Unsupported Media Type response when either the method request content type does not match any content type associated with the mapping templates defined in the integration request or no mapping template is defined in the integration request.

contentHandling -> (string)

Specifies how to handle request payload content type conversions. Supported values are CONVERT_TO_BINARY and CONVERT_TO_TEXT , with the following behaviors:

• CONVERT_TO_BINARY : Converts a request payload from a Base64-encoded string to the corresponding binary blob.

• CONVERT_TO_TEXT : Converts a request payload from a binary blob to a Base64-encoded string.

If this property is not defined, the request payload will be passed through from the method request to integration request without modification, provided that the passthroughBehavior is configured to support payload pass-through.

timeoutInMillis -> (integer)

Custom timeout between 50 and 29,000 milliseconds. The default value is 29,000 milliseconds or 29 seconds.

cacheNamespace -> (string)

Specifies a group of related cached parameters. By default, API Gateway uses the resource ID as the cacheNamespace . You can specify the same cacheNamespace across resources to return the same cached data for requests to different resources.

cacheKeyParameters -> (list)

A list of request parameters whose values API Gateway caches. To be valid values for cacheKeyParameters , these parameters must also be specified for Method requestParameters .

(string)

integrationResponses -> (map)

Specifies the integration’s responses.

Example: Get integration responses of a method Request

GET /restapis/fugvjdxtri/resources/3kzxbg5sa2/methods/GET/integration/responses/200 HTTP/1.1 Content-Type: application/json Host: apigateway.us-east-1.amazonaws.com X-Amz-Date: 20160607T191449Z Authorization: AWS4-HMAC-SHA256 Credential={access_key_ID}/20160607/us-east-1/apigateway/aws4_request, SignedHeaders=content-type;host;x-amz-date, Signature={sig4_hash} Response

The successful response returns 200 OK status and a payload as follows:

{ "_links": { "curies": { "href": "https://docs.aws.amazon.com/apigateway/latest/developerguide/restapi-integration-response-{rel}.html", "name": "integrationresponse", "templated": true }, "self": { "href": "/restapis/fugvjdxtri/resources/3kzxbg5sa2/methods/GET/integration/responses/200", "title": "200" }, "integrationresponse:delete": { "href": "/restapis/fugvjdxtri/resources/3kzxbg5sa2/methods/GET/integration/responses/200" }, "integrationresponse:update": { "href": "/restapis/fugvjdxtri/resources/3kzxbg5sa2/methods/GET/integration/responses/200" } }, "responseParameters": { "method.response.header.Content-Type": "'application/xml'" }, "responseTemplates": { "application/json": "$util.urlDecode(\"%3CkinesisStreams%3E#foreach($stream in $input.path('$.StreamNames'))%3Cstream%3E%3Cname%3E$stream%3C/name%3E%3C/stream%3E#end%3C/kinesisStreams%3E\")\n" }, "statusCode": "200" }

Creating an API

key -> (string)

value -> (structure)

Represents an integration response. The status code must map to an existing MethodResponse , and parameters and templates can be used to transform the back-end response.

Creating an API

statusCode -> (string)

Specifies the status code that is used to map the integration response to an existing MethodResponse .

selectionPattern -> (string)

Specifies the regular expression (regex) pattern used to choose an integration response based on the response from the back end. For example, if the success response returns nothing and the error response returns some string, you could use the .+ regex to match error response. However, make sure that the error response does not contain any newline (\n ) character in such cases. If the back end is an AWS Lambda function, the AWS Lambda function error header is matched. For all other HTTP and AWS back ends, the HTTP status code is matched.

responseParameters -> (map)

A key-value map specifying response parameters that are passed to the method response from the back end. The key is a method response header parameter name and the mapped value is an integration response header value, a static value enclosed within a pair of single quotes, or a JSON expression from the integration response body. The mapping key must match the pattern of method.response.header.{name} , where name is a valid and unique header name. The mapped non-static value must match the pattern of integration.response.header.{name} or integration.response.body.{JSON-expression} , where name is a valid and unique response header name and JSON-expression is a valid JSON expression without the $ prefix.

key -> (string)

value -> (string)

responseTemplates -> (map)

Specifies the templates used to transform the integration response body. Response templates are represented as a key/value map, with a content-type as the key and a template as the value.

key -> (string)

value -> (string)

contentHandling -> (string)

Specifies how to handle response payload content type conversions. Supported values are CONVERT_TO_BINARY and CONVERT_TO_TEXT , with the following behaviors:

• CONVERT_TO_BINARY : Converts a response payload from a Base64-encoded string to the corresponding binary blob.

• CONVERT_TO_TEXT : Converts a response payload from a binary blob to a Base64-encoded string.

If this property is not defined, the response payload will be passed through from the integration response to the method response without modification.

tlsConfig -> (structure)

Specifies the TLS configuration for an integration.

insecureSkipVerification -> (boolean)

Specifies whether or not API Gateway skips verification that the certificate for an integration endpoint is issued by a supported certificate authority . This isn’t recommended, but it enables you to use certificates that are signed by private certificate authorities, or certificates that are self-signed. If enabled, API Gateway still performs basic certificate validation, which includes checking the certificate’s expiration date, hostname, and presence of a root certificate authority. Supported only for HTTP and HTTP_PROXY integrations.

authorizationScopes -> (list)

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.

(string)
