问题 I have a serverless lambda function written in Node.JS. What is the best / correct way of returning error codes?

问题 I'm writing unit tests for a serverless application in TypeScript, and I'd like to mock the AWS SDK. Unfortunately I have not found many existing type definitions for popular AWS mocking projects. In particular I'd like to use the aws-sdk-mock library, but without its type definitions I can't. Theoretically I'd like to be able to do something like: import 'jest'; import * as sinon from 'sinon'; import * as _ from 'lodash'; import { handler } from '../lib/lambda'; import AWSMock from 'aws-sdk

问题 I am using AWS API Gateway with a proxy Lambda, when the name of the lambda function is coming as a stage variable. Meaning I have a single API integration which connects to appropriate lambda according to the deployed stage.

Things I already

When a lambda function is triggered - I may want to retry same message again after 5 minute without deleting the message from the Queue. The reason I want to do this if Lambda could not connect external host (eg: API) - i like to try again after 5 minutes for 3 attempts only. How can that be written in node js? For example in Laravel, we can Specifying Max Job Attempts functionality.

问题 I need to authorize my API end point using aws cognito userpool. I can do it manually, but I need to automate the authorization part with the serverless framework. Does the Serverless framework have support for aws cognito? If so, how do we setup an aws-userpool with serverless? 回答1: Yes . Serverless ( v1.5 ) support to Cognito user pool authorizer.

问题 I'm currently using a Cognito User Pool as an authorizer for an API Gateway endpoint, through to a Lambda function. Can I pass the Integrated Request on to Lambda and SECURELY allow or deny from inside Lambda based on a custom attribute? Mapping: "administrator" : "$context.authorizer.claims['custom:administrator']", Lambda handler: boolean isAdmin = Boolean.parseBoolean(request.getContext().get("administrator")); if(isAdmin) etc... To be clear, a user that is NOT an administrator should not
