AWS Lambda Webhook 事件处理，NodeJS 到 Python

Question

I got this NodeJS code from a coworker. This code is in AWS lambda and handles incoming events which are sent per webhook. Inside this code I specify a Kinesis Firehose delivery stream which then sends the data to a bucket. I have the delivery stream in between to do some zipping and adding partition. 2nd thing that is important in this code is the part where I take the body of the incoming event and send it as json to the delivery stream.

Can someone help me to interpret this code to python?

 const AWS = require( 'aws-sdk' ); const firehose = new AWS.Firehose(); exports.handler = async (event) => { console.log(JSON.stringify(event, null, 4)); try { await firehose .putRecord({ DeliveryStreamName: 'foo', Record: { Data:event.body } }) .promise(); } catch (error) { console.error(error); return { statusCode: 400, body: `Cannot process event: ${error}` }; } return { statusCode: 200, body: JSON.stringify({ ack: new Date().getTime() }) }; };

You can use Boto3 Python AWS SDK

import json
import boto3
from datetime import datetime

client = boto3.client('firehose')

def handler(event): 
    print(json.dumps(event, indent=4))
    try:
        response = client.put_record(
        DeliveryStreamName='string',
        Record={
            'Data': event.body
        }
    )
    except Exception as e:
        return {
            'statusCode': 400,
            'body': json.dumps(f'Cannot process event: {e}')
        }

    return {
        'statusCode': 200,
        'body': json.dumps({ 'ack': datetime.now().strftime('%H:%M:%S') })
    }
