amazon-web-services - 带有Cognito用户池授权者的AWS SAM API

如何使用AWS SAM创建使用Cognito用户池授权者进行授权的API？

Theres AWS::ApiGateway::Authorizer。但是...

{
  "Type" : "AWS::ApiGateway::Authorizer",
  "Properties" : {
    "AuthorizerCredentials" : String,
    "AuthorizerResultTtlInSeconds" : Integer,
    "AuthorizerUri" : String,
    "IdentitySource" : String,
    "IdentityValidationExpression" : String,
    "Name" : String,
    "ProviderARNs" : [ String, ... ],
    "RestApiId" : String,
    "Type" : String
  }
}

看起来RestApiId是指使用此授权器的API？但是使用AWS SAM，我的API定义如下

Resources:
  Ec2Index:
    Type: AWS::Serverless::Function
    Properties:
      Handler: ec2/index.handler
      Runtime: nodejs6.10
      CodeUri: ./src
      FunctionName: 'ApiEc2IndexHandler'
      Description: 'List EC2 resources'
      Timeout: 30
      Role: 'arn:aws:iam::598545985414:role/awsmanagement-lambda-management'
      Events:
        Ec2Index:
          Type: Api
          Properties:
            Path: /ec2
            Method: get

我不知道如何将它们联系在一起？

最佳答案

我不确定您是否可以在SAM中指定授权者，但是可以将Swagger嵌入到SAM文件中来执行此操作。它是2月17日[ref]的新功能。

我绝对不是Swagger或SAM的专家，但似乎您想要这样的东西：

编辑：修复了“安全”部分的Swagger 2.0语法，它应该是一个列表。
