无服务器自定义授权器结果未定义

Question

我按照在线教程和示例学习如何为我的 lambda 函数实现自定义授权方。不幸的是，我无法访问函数内的授权方上下文。执行 console.log(event.requestContext.authorizer); 只会导致 undefined。我错过了什么吗？这是一些片段。

# serverless.yml

...
myAuthorizer:
  handler: src/functions/myAuthorizer/index.handler

someFunction:
  handler: src/functions/someFunction/index.handler
  events:
    - http:
        method: GET
        path: /hello-world
        authorizer:
          name: myAuthorizer
          identitySource: method.request.header.Authorization

// myAuthorizer.ts

export async function handler(
  event: AWSLambda.CustomAuthorizerEvent,
  context: AWSLambda.Context
): Promise<AWSLambda.AuthResponse> {

  const user = {id: 1, email: 'user@test.com'};

  // some logic...

  return {
    principalId: user.id,
    policyDocument: {
      Version: '2012-10-17',
      Statement: [
        {
          Action: '*',
          Effect: 'Allow',
          Resource: '*',
        },
      ],
    },
    context: { user },
  };
}

// someFunction.ts

export async function handler(
  event: AWSLambda.APIGatewayEvent,
  context: AWSLambda.Context
): Promise<AWSLambda.APIGatewayProxyResult> {

  console.log(event.requestContext.authorizer); // <-- this is undefined
  console.log(Object.keys(event.requestContext)); // <-- no "authorizer" property
  return {
    statusCode: 200,
    body: JSON.stringify({hello: 'world'}),
  };
}

提前致谢！

在 myAuthorizer 处理函数中，使用 callback 风格而不是 async/await 风格。

export async function handler(
  event: AWSLambda.CustomAuthorizerEvent,
  context: AWSLambda.Context
): Promise<void> { // change to void

  const user = { id: 1, email: 'user@test.com' };

  // some logic...

  context.succeed({ // instead of return policy object
    principalId: user.id,
    policyDocument: {
      Version: '2012-10-17',
      Statement: [
        {
          Action: '*',
          Effect: 'Allow',
          Resource: '*',
        },
      ],
    },
    context: { user },
  });
}
