amazon-web-services - 如何构建 AWS CloudFormation 集成 URI，以便 AWS ApiGateway 与 S3、SQS、SNS、DynamoDB 和其他服务集成？

Question

是否有一些地方提供有关如何通过 ApiGateway 集成进行一系列操作的示例？了解如何将对象上传到 S3、将项目推送到 SQS 和 SNS 队列、进行 DynamoDB 调用以及许多其他操作，尝试找到有关如何构建这些路径的文档。

我正在使用 CloudFormation 模板，该模板使用集成 URI 来设置 AWS ApiGateway 与 AWS 服务的集成。

找不到说明如何为所有类型的服务创建这些 URI 路径的文档。

Answer 1

设置与其他 AWS 服务操作的集成请求时，集成请求 URI 也是 ARN。

例如，对于与 Amazon S3 的 GetBucket 操作集成，集成请求 URI 是以下格式的 ARN:

arn:aws:apigateway:api-region:s3:路径

Dynamodb:比S3复杂一点: https://aws.amazon.com/blogs/compute/using-amazon-api-gateway-as-a-proxy-for-dynamodb/

对于 SQS，我找到了 cloudformation 设置:

PostMethod:
    Type: "AWS::ApiGateway::Method"
    Properties:
      AuthorizationType: "NONE"
      ApiKeyRequired: "true"
      HttpMethod: "POST"
      ResourceId: !Ref "SomeResource"
      RestApiId: !Ref "RestApi"
      MethodResponses:
      - StatusCode: 200
      Integration:
        Credentials: !GetAtt "RestApiRole.Arn"
        IntegrationHttpMethod: "POST"
        IntegrationResponses:
        - StatusCode: 200
        Type: "AWS"
        Uri: !Sub "arn:aws:apigateway:${AWS::Region}:sqs:action/SendMessage"
        RequestParameters:
          integration.request.querystring.QueueUrl: !Sub "'${SomeQueue}'"
          integration.request.querystring.MessageBody: "method.request.body"

这里是 RestApiRole 的代码:

RestApiRole:
    Type: "AWS::IAM::Role"
    Properties:
      AssumeRolePolicyDocument:
        Version: "2012-10-17"
        Statement:
        - Action:
          - "sts:AssumeRole"
          Principal:
            Service:
            - "apigateway.amazonaws.com"
          Effect: "Allow"
      Policies:
      - PolicyName: "InvokeLambda"
        PolicyDocument:
          Version: "2012-10-17"
          Statement:
          - Action:
            - "lambda:InvokeFunction"
            Resource: !GetAtt "LambdaFunction.Arn"
            Effect: "Allow"
