aws-lambda

问题 I was previously using the all-in-one aws-sdk npm module (https://www.npmjs.com/package/aws-sdk) to invoke an AWS Lambda function, and for that the following code had been working well: //Some code to get "credentials" ... const AWS = require('aws-sdk'); const lambda = new AWS.Lambda({ accessKeyId: credentials.accessKeyId, secretAccessKey: credentials.secretAccessKey, region: Config.REGION }); lambda.invoke(pullParams, (err, data) => //I would do something with data ); ... Now, taking a cue

问题 I am new to aws lambda. I am trying to send mail with aws ses with aws lambda, without any triggers.

问题 I'm working on a NodeJS project and using pretty common AWS setup it seems. My ApiGateway receives call, triggers lambda A, then this lambda A triggers other lambdas, say B or C depending on params passed from ApiGateway. Lambda A needs to access MongoDB and to avoid hassle with running MongoDB myself I decided to use mLab. ATM Lambda A is accessing MongoDB using NodeJS driver. Now, not to start connection with every Lambda A execution I use connection pool, again, inside of Lambda A code,

问题 I'm using the AWSMobileClient on iOS for authentication and I'm not able to sign in. I'm calling the signin method and all I'm getting is the following error: The operation couldn’t be completed. (AWSMobileClient.AWSMobileClientError error 13.) This error is useless to me and I can't find any decent documentation on what this error means. Has anyone seen this? Appreciate your help. 回答1: Please take a look at this https://github.com/aws-amplify/aws-sdk-ios/issues/1538#issuecomment-491905913

问题 Unhandled rejection Error: Could not execute GraphicsMagick/ImageMagick: gm "identify" "-ping" "-format" "%p" "/tmp/temp.pdf" this most likely means the gm/convert binaries can't be found I have tried everything mentioned in similar questions. This is my first lambda function and I am stuck. Please find below how I am adding gm into my lambda function index.js // dependencies var AWS = require('aws-sdk'); var simpleParser = require('mailparser').simpleParser; const gm = require('gm').subclass

问题 I need a better way to update a static website that is hosted in an AWS S3 bucket. Whenever I am wanting to update my personal site that I have hosted through a S3 bucket, I have to deleting the index.html file and the assets folder from the S3 bucket, then re-upload the new files. I am doing this through the AWS web interface. Is there a way to use a different AWS service to do this in a way similar to git where I can push updated code? Possibly with lambda? 回答1: You cant automate the whole

问题 What is the easiest approach (easiest implies low number of service maintenance overhead. Would prefer server less approach if possible) to copy data from a DDB table in one account to another, preferably in server less manner (so no scheduled jobs using Data pipelines). I was exploring possibility of using DynamoDB streams, however this old answer mentions that is not possible. However, I could not find latest documentation confirming/disproving this. Is that still the case? Another option I

问题 I'd like to have an AWS lambda triggered when a tag is added to an existing object in S3 bucket (in the same way as we can do it for object create and remove). Any way to do that? 回答1: If you setup Cloudtail you could have a Lambda function monitor the logs and notify you on the tagging event PutBucketTagging Example Lambda function https://github.com/retailnext/aws-lambda-cloudtrail-alert Cloudtail Documentation http://docs.aws.amazon.com/awscloudtrail/latest/userguide/cloudtrail-user-guide

问题 This problem has been driving me nuts for two days now. The objective: Upload an image directly from the browser to S3 via a pre-signed URL supplied by the getSignedUrl function in the AWS Javascript SDK. I haven't had any problems generating URLs with getSignedUrl. The following code... const params = { Key: key, Bucket: process.env.S3_BUCKET, ContentType: "image/jpeg" }; S3.getSignedUrl("putObject", params, callback); ...yields something like: https://s3.amazonaws.com/foobar-bucket
