问题描述
我正在学习使用AWS Lambda和api网关。我从sam cli开始,初始化了一个hello world模板(下面的代码)。当通过-sam package ...命令生成deploy.yaml文件并且通过云形成生成堆栈时,看起来这已经生成了api端点。我想用资源,方法,使用计划,API密钥等创建一个api网关。因此我开始将以下资源添加到原始模板中。如何使用lambda函数连接api网关。
ApiGatewayRestApi:
Type: AWS::ApiGateway::RestApi
Properties:
ApiKeySourceType: HEADER
Description: An API Gateway with a Lambda Integration
EndpointConfiguration:
Types:
- EDGE
Name: lambda-api
ApiGatewayResource:
Type: AWS::ApiGateway::Resource
Properties:
ParentId: !GetAtt ApiGatewayRestApi.RootResourceId
PathPart: 'lambda'
RestApiId: !Ref ApiGatewayRestApi
ApiGatewayMethod:
Type: AWS::ApiGateway::Method
Properties:
ApiKeyRequired: false
AuthorizationType: NONE
HttpMethod: GET
ResourceId: !Ref ApiGatewayResource
RestApiId: !Ref ApiGatewayRestApi
原始模板
