Я пытаюсь создать шлюз API, указывающий на лямбду через прокси, используя cloudformation:
Сначала я создаю свой рут и даю ему разрешение:
RestApiHamed:
Type: 'AWS::ApiGateway::RestApi'
Properties:
Name: hamed-proxy-test
APIGatewayToLambdaPermission:
Type: AWS::Lambda::Permission
DependsOn: RestApiHamed
Properties:
Action: lambda:invokeFunction
FunctionName: test-stg1-lambda-product-get
Principal: apigateway.amazonaws.com
SourceArn: #!Sub "arn:aws:execute-
api:${AWS::Region}:${AWS::AccountId}:RestApiHamed/*"
Fn::Join:
- ''
- - 'arn:aws:execute-api:'
- Ref: AWS::Region
- ":"
- Ref: AWS::AccountId
- ":"
- Ref: RestApiHamed
- "/*"
Затем я создаю свой метод:
ChannelsStoriesGetMethod:
Type: AWS::ApiGateway::Method
DependsOn: APIGatewayToLambdaPermission
Properties:
AuthorizationType: NONE
HttpMethod: GET
Integration:
Type: HTTP
IntegrationHttpMethod: GET
IntegrationResponses:
-
StatusCode: 200
Type: AWS_PROXY
Uri: !Sub arn:aws:apigateway:${AWS::Region}:lambda:path/2015-03-31/functions/arn:aws:lambda:us-east-1:048947288163:function:zuora-stg1-lambda-product-get/invocations
ResourceId: !Ref ChannelsStoriesPath
RestApiId:
Ref: RestApiHamed
MethodResponses:
- StatusCode: 200
ResponseParameters:
method.response.header.Access-Control-Allow-Origin: true
Теперь, когда я запускаю облачную информацию, она оказывается успешной, и я вижу свои ворота, но когда я пробую шлюз, я получаю:
<Message>Unable to determine service/operation name to be
authorized</Message>
</AccessDeniedException>
Execution failed due to configuration error: Malformed Lambda proxy response
Но как только я перехожу к запросу на интеграцию и нажимаю clcik для редактирования в лямбда-функции, а затем нажимаю кнопку «Сохранить», я получаю всплывающее окно с запросом на вложение разрешений, и когда я принимаю это, оно начинает работать. В чем проблема?
Я добавляю разрешение в мой код cfn и ожидаю, что этот кусок, как вы видите, выполняет свою работу. Должен ли я добавить что-нибудь еще?
Полный код CFN выглядит следующим образом:
