SAM Local似乎没有运行授权程序功能

我刚开始用 SAM Local ,但在尝试为我的终结点配置授权程序函数时,我又遇到了一个问题。

我一直在看 main SAM documentation 了解如何设置Auth函数,但是每当我尝试在本地运行API时 sam local start-api ,它运行得很好,但好像它甚至没有尝试运行auth函数。

我尝试在Global.API中定义Auth,并在SAM的resource s部分中定义API资源 模板.yaml

# template.yaml
Globals:
  Function:
    Timeout: 3
    CodeUri: src/
    Runtime: nodejs8.10
  Api:
    Auth:                        # Option #1: Defining it globally
      DefaultAuthorizer: CustomJWTAuthorizer
      Authorizers:
        CustomJWTAuthorizer:
          FunctionArn: !GetAtt AuthFunction.Arn    
Resources:
  UserApi:
    Auth:                        # Option #2: Defining it as an API resource
      Authorizers:
        MyLambdaTokenAuth:
          FunctionPayloadType: TOKEN
          FunctionArn: !GetAtt AuthFunction.Arn
      DefaultAuthorizer: MyLambdaTokenAuth
  GetUserFunction:
    Type: AWS::Serverless::Function
    Properties:
      Handler: handler.getUser
      Events:
        GetUser:
          Type: Api
          Properties:
            Path: /users/{userId}
            Method: get
            Auth:                    # Option #3: Define it on the function level
              Authorizer: AuthFunction
            RestApiId:
                Ref: UserApi
  AuthFunction:
    Type: AWS::Serverless::Function
    Properties:
      Handler: handler.authorize

我试过将事件打印到控制台,可以看到 event.requestContext 只是用虚拟数据填充,而不是在实时推送时传递:

  // console.log(event)

  ...  
  resource: '/users/{userId}', 
  requestContext:     { resourceId: '123456',
     apiId: '1234567890',
     resourcePath: '/users/{userId}',
     httpMethod: 'GET',
     requestId: 'c6af9ac6-7b61-11e6-9a41-93e8deadbeef',
     accountId: '123456789012',
     stage: null,
     identity: 
      { apiKey: null,
        userArn: null,
        cognitoAuthenticationType: null,
        caller: null,
        userAgent: 'Custom User Agent String',
        user: null,
        cognitoIdentityPoolId: null,
        cognitoAuthenticationProvider: null,
        sourceIp: '127.0.0.1',
        accountId: null },
   extendedRequestId: null,
   path: '/users/{userId}' },
   ...
