如何调用API网关授权器后面的lambda

Question

我有下面的CloudFormation堆栈。2个lambda（问候和Auth）,API网关配置为使用Auth lambda进行授权。

AWSTemplateFormatVersion: "2010-09-09"
Transform: AWS::Serverless-2016-10-31
Resources:
  GreetingsApiGateway:
    Type: AWS::Serverless::Api
    Properties:
      StageName: Prod
      Auth:
        DefaultAuthorizer: MyAuthorizer
        Authorizers:
          MyAuthorizer:
            FunctionArn: !GetAtt AuthLambda.Arn

  GreetingsLambda:
    Type: AWS::Serverless::Function
    Properties:
      CodeUri: "s3://<bucket-name>/code.zip"
      Handler: src/index.greeting
      Events:
        GetRoot:
          Type: Api
          Properties:
            RestApiId: !Ref GreetingsApiGateway
            Path: /hello
            Method: get

  AuthLambda:
    Type: AWS::Serverless::Function
    Properties:
      CodeUri: "s3://<bucket-name>/code.zip"
      Handler: src/index.auth

Globals:
  Function:
    Runtime: nodejs8.10
  # check whether I can use resources within globals

Outputs:
  ApiURL:
    Description: "OUR API URL"
    Value: !Sub "https://${GreetingsApiGateway}.execute-api.${AWS::Region}.amazonaws.com/Prod/"

我的lambdas的代码如下：

exports.greeting = async () => ({ statusCode: 200, body: "Hello Beautiful World!" });

exports.auth = async () => ({ statusCode: 200, body: "I wanna do the authorisation!" });

我尝试在GET请求的头中发送此输入。响应为“未经授权”，没有来自Auth lambda CloudWatch日志中的任何日志。

{
    "type":"TOKEN",
    "authorizationToken":"<caller-supplied-token>",
    "methodArn":"arn:aws:execute-api:<regionId>:<accountId>:<apiId>/<stage>/<method>/<resourcePath>"
}

发生什么事了？

为了检索响应，我们需要使用授权头，仍然不明白为什么从API网关控制台的请求检索到响应。
