lambda-tweet

Summary

Sample AWS Lambda application written in python to tweet images that have been uploaded to an S3 bucket.

Requirements

This lambda function assumes it has access to a file called config.json which has an entry called secrets. Secrets is a json object that has been encrypted using AWS KMS and base64 encoded. The secrets has the following structure:

{
    "consumer-key": "Twitter API consumer key",
    "consumer-secret": "Twitter API consumer secret",
    "access-token": "Twitter API access token", 
    "access-token-secret": "Twitter API access token secret"
}

Usage

The bulk of the logic to send the image to twitter lives in the TweetS3Images class. This class requires a tweepy API object and a boto3 S3 client.

You can use it like such:

auth = tweepy.OAuthHandler(consumer_key, consumer_secret)
auth.set_access_token(access_token, access_token_secret)
api = tweepy.API(auth)
boto_session = boto3.session.Session(profile_name='mindtouch', region_name='us-west-2')
client = boto_session.client('s3')

tweet_images = TweetS3Images(api, client)
tweet_images.send_image('juant-test', 'image.jpg')
