Amazon web services AWS SAM部署，如何查找API网关的URL？

从命令行部署后，如何查找API网关的URL地址？

我使用一个类似于下面的脚本来部署API网关和授权器，它部署得很好

https://github.com/floodfx/aws-lambda-proxy-using-sam-local/blob/master/deploy.sh

我正试图找出如何在部署后从命令行获取API网关的地址

API网关被创建，我可以看到堆栈：

aws cloudformation describe-stacks

---

必须有一个简单的命令我没有得到这一点。

我刚刚有时间正确回答。具有API网关定义：

Resources:
  ...
  ServerlessRestApi:
    Type: AWS::Serverless::Api
    DeletionPolicy: "Retain"
    Properties:
      StageName: Prod
  ...

您可以输出

Outputs:
  ProdDataEndpoint:
    Description: "API Prod stage endpoint"
    Value: !Sub "https://${ServerlessRestApi}.execute-api.${AWS::Region}.amazonaws.com/Prod/"

---

我有单独的

AWS:：ApiGateway:：RestApi

和

AWS:：ApiGateway:：Stage

资源，因此我的输出看起来有点不同，因为我没有/无法硬编码Stage名称：

Outputs:
  ProdEndpoint:
    Value: !Sub "https://${ApiGw}.execute-api.${AWS::Region}.amazonaws.com/${ApiGwStage}/"

Resources:
  ApiGw:
    Type: AWS::ApiGateway::RestApi
    Properties:
      Name: 'Serverless Ipsum #noServerNovember challenge'
      FailOnWarnings: true

  ApiGwDeployment:
    Type: AWS::ApiGateway::Deployment
    # Required -- see https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-apigateway-deployment.html
    DependsOn: ApiGwMethod
    Properties:
      RestApiId: !Ref ApiGw

  ApiGwStage:
    Type: AWS::ApiGateway::Stage
    Properties:
      DeploymentId: !Ref ApiGwDeployment
      MethodSettings:
        - DataTraceEnabled: true
          HttpMethod: '*'
          LoggingLevel: INFO
          ResourcePath: '/*'
      RestApiId: !Ref ApiGw
      StageName: prod

  ApiGwResource:
    Type: AWS::ApiGateway::Resource
    Properties:
      RestApiId: !Ref ApiGw
      ParentId: !GetAtt ["ApiGw", "RootResourceId"]
      PathPart: "{proxy+}"

  ApiGwMethod:
    Type: AWS::ApiGateway::Method
    Properties:
      RestApiId: !Ref ApiGw
      ResourceId: !Ref ApiGwResource
      HttpMethod: ANY
      AuthorizationType: NONE
      Integration:
        Type: AWS_PROXY
        IntegrationHttpMethod: POST
        Uri: !Sub "arn:aws:apigateway:${AWS::Region}:lambda:path/2015-03-31/functions/${ServerlessIpsumFunction.Arn}/invocations"

您可以使用cloudformation模板的输出参数导出资源引用，我刚才看到了。。也许它会帮助其他人我会添加一个示例输出：示例APIURL:Value:！Sub“https://${ExampleAPI}.executeAPI.${AWS:：Region}.amazonaws.com/${StageName}/”我在github上举了一些例子，如果有人仍在努力解决这个问题：如何在运行时获得该输出的值？Op指定的SAM部署（不显式创建资源）。

Outputs:
  ProdEndpoint:
    Value: !Sub "https://${ApiGw}.execute-api.${AWS::Region}.amazonaws.com/${ApiGwStage}/"

Resources:
  ApiGw:
    Type: AWS::ApiGateway::RestApi
    Properties:
      Name: 'Serverless Ipsum #noServerNovember challenge'
      FailOnWarnings: true

  ApiGwDeployment:
