允许无服务器端点接收授权令牌

Question

如何配置serverless.yml以允许端点读取授权令牌并将其发送到lambda函数以处理此函数中的授权？我只想比较Authorization令牌和硬编码值。我尝试使用自定义授权者：

custom:
  authorizer:
    users:
      name: authorizer
      type: TOKEN
      identitySource: method.request.header.Authorization
      identityValidationExpression: ^(.{64}$)
functions:
  authorizer:
    environment:
      PASS_PHRASE: "DB886057AEAFF1BC44136561940B40146B77BB39AD8DC7EBB20AEF6E25A6CB93"
    handler: src/handler.authorize
  recource:
    handler: src/handler.handle   
    events:
      - http:
          path: /recource
          method: get
          cors:  true
          authorizer: ${self:custom.authorizer.users}
      - http:
          path: /recource
          method: options
          cors: true
          documentation:
            description: "Options"

但不起作用。我收到：

{
    "message": "Authorization header requires 'Credential' parameter. Authorization header requires 'Signature' parameter. Authorization header requires 'SignedHeaders' parameter. Authorization header requires existence of either a 'X-Amz-Date' or a 'Date' header. Authorization=DB886057AEAFF1BC44136561940B40146B77BB39AD8DC7EBB20AEF6E25A6CB93"
}
