【问题描述】：
我正在尝试使用 cloudformation 通过代理创建一个指向 lambda 的 api 网关：
首先我创建我的根并授予它权限：
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
- "/*"
然后我创建我的方法：
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
现在，当我运行 cloudformation 时，它成功了，我可以看到我的网关，但是当我尝试网关时，我得到了：
<Message>Unable to determine service/operation name to be
authorized</Message>
</AccessDeniedException>
Execution failed due to configuration error: Malformed Lambda proxy response
但是，一旦我转到集成请求并在 lambda 函数中编辑 clcik，然后单击保存，我就会弹出一个询问权限附件的窗口，当我接受时，它就会开始工作。问题是什么？ 我确实在我的 cfn 代码中添加了权限，并且我希望您可以看到该部分可以完成这项工作。我应该添加其他内容吗？
完整的cfn代码如下：
