问题 I need to access event["pathParameters"] but the event returns an empty object. I created the function with AWS Cloud9 IDE. Here is my simple function: def handler(event, context): return { 'statusCode': 200, 'body': json.dumps(event), 'headers': { 'Content-Type': 'application/json' } } 回答1: event is set by the payload you're invoking the lambda with. When you use API gateway, that payload includes the key pathParameters , but when you're testing using the lambda console you'll need to form

问题 I have a lambda function which needs to access ec2 through ssh and load files and save it to s3. So,for that I have kept ec2 and lambda both in default VPCs and same subnet. Now the problem is that I am able to connect the function to ec2 but not to s3. Its killing me since morning as when I remove the vpc settings it uploads the files to s3 ,but then connection to ec2 is lost. I tried to add a NAT gateway to default VPC(although I am not sure I did it correctly or not because I am new to

问题 Is there a way to configure on S3 Lifecycle to delete object less than 30 days (say I want to delete in 5 days Permanently without moving to any other Storage class like glacier? Or should I go by other alternative like Lambda ? I believe, S3 'Lifecycle Rule' allows storage class only more than 30 days. 回答1: You can use expiration action: Define when objects expire. Amazon S3 deletes expired objects on your behalf. You can set expiration time to 5 days or 1 day, or what suits you. For example

问题 I want to build a codepipeline that will get the code(java) from github build a jar file and deploy it to aws lamda(or store the jar in a specific S3 bucket). I only want to use tools provided by AWS platform only. If I am using only Codebuild I am able to build jar from the github code and store it to S3(https://docs.aws.amazon.com/codebuild/latest/userguide/getting-started.html) and I am using a deployer lamda function to deploy the code to my service lamda. Whenever there is any change in

问题 Sorry for this loaded question. I. TL;DR: The /tmp directory on AWS Lambda keeps filling up when it shouldn't and gives me ENOSPC error on subsequent request. II. The TL version: I have a microservice built with Node JS (0.10x) on AWS Lambda that does 2 things: Given a list of urls, it goes to relevant sources (S3, Cloudfront, thumbor, etc.) and download the physical files into the /tmp directory After downloading all of these files, it will compress them into a tar ball and upload to S3.

问题 Im using Api Gateway and AWS Lambda and AWS RDS to build an API. My Lambda Function Code is Java. Currently im using the AWS Systems Manager Parameter Store successfully to connect to my Database. Therefore I created a parameter called "connection" which has the type String and holds my complete connection url. In Lambda functions i can access this parameter successfully this way: GetParameterRequest parameterRequest = new GetParameterRequest().withName("connection").withWithDecryption(false)
