Question

我正在通过CloudFormation部署Lambdas（和APIGateway配置），最终使用Serverless。

pathmapping中生成的CloudFormation cloudformation-template-update-stack.json部分如下所示：

"pathmapping": {
      "Type": "AWS::ApiGateway::BasePathMapping",
      "Properties": {
        "BasePath": "demolambda",
        "DomainName": "staging-api.<REDACTED>",
        "RestApiId": {
          "Ref": "ApiGatewayRestApi"
        },
        "Stage": "staging"
      }
    }

当这个运行时，我收回错误：

pathmapping - Invalid stage identifier specified.

我不确定这意味着什么。堆栈上传到S3，一切看起来都不错，但是，无论我如何玩它，我都会继续收到这条消息。

好奇是否有人对导致此问题或如何解决问题有任何想法？

Answer 1

运行堆栈时，我将部署的API stageName与BasePathMapping stageName保持相同，并且能够成功创建映射。另外，在创建时，我还提供了域的特定证书。

ApiGatewayDomainName:
    Type: AWS::ApiGateway::DomainName
    Properties:      
      CertificateArn:
        Fn::ImportValue:  !Sub "mycertificates-UserCertificateArn"             
      DomainName:
          Ref: ApiDomainName

 ApiGatewayBasePathMapping:
    Type: AWS::ApiGateway::BasePathMapping
    Properties:
      DomainName:
        Ref: ApiDomainName
      RestApiId:
        Ref: ApiGatewayRestApi
      Stage: !Sub "${EnvironmentName}"
    DependsOn: ApiGatewayDomainName

首先，您需要资源AWS::ApiGateway::Stage。此资源取决于AWS::ApiGateway::Deployment

然后使AWS::ApiGateway::BasePathMapping依赖于AWS::ApiGateway::Stage：

这是我经过测试的解决方案：

Resources:
  apiDomainName:
    Type: "AWS::ApiGateway::DomainName"
    Properties:
      CertificateArn: <CertificateArn>
      DomainName: <DomainName>
      SecurityPolicy: 'TLS_1_2'
      EndpointConfiguration:
        Types:
          - EDGE
  apiGateway:
    Type: 'AWS::ApiGateway::RestApi'
...
  apiGatewayDeployment:
    Type: 'AWS::ApiGateway::Deployment'
    Properties:
      RestApiId: !Ref apiGateway
  apiGatewayStage:
    Type: "AWS::ApiGateway::Stage"
    Properties:
      DeploymentId: !Ref apiGatewayDeployment
      RestApiId: !Ref apiGateway
      StageName: <stage>
...
  apiGatewayMapping:
    Type: "AWS::ApiGateway::BasePathMapping"
    DependsOn:
      - apiGatewayStage
    Properties:
      BasePath: <path>
      DomainName: <DomainName>
      RestApiId: !Ref apiGateway
      Stage: <stage>

AWS CloudFormation：pathmapping - 指定的阶段标识符无效
