Voici ce que je veux faire:
Environnement local
Framework sans serveur version 1.22.0
Python 2.7
Voici mon fichier serverless.yml
service: aws-python # NOTE: update this with your service name
provider:
name: aws
runtime: python2.7
stage: dev
region: us-east-1
iamRoleStatements:
- Effect: "Allow"
Action:
- s3:*
- "ses:SendEmail"
- "ses:SendRawEmail"
- "s3:PutBucketNotification"
Resource: "*"
functions:
csvfile:
handler: handler.csvfile
description: send mail whenever a csv file is uploaded on S3
events:
- s3:
bucket: mine2
event: s3:ObjectCreated:*
rules:
- suffix: .csv
et voici ma fonction lambda:
import json
import boto3
import botocore
import logging
import sys
import traceback
import csv
from botocore.exceptions import ClientError
from pprint import pprint
from time import strftime, gmtime
from json import dumps, loads, JSONEncoder, JSONDecoder
#setup simple logging for INFO
logger = logging.getLogger()
logger.setLevel(logging.INFO)
from botocore.exceptions import ClientError
def csvfile(event, context):
"""Send email whenever a csvfile is uploaded to S3 """
body = {}
emailcontent = ''
status_code = 200
#set email information
email_from = '****@*****.com'
email_to = '****@****.com'
email_subject = 'new file is uploaded'
try:
s3 = boto3.resource(u's3')
s3 = boto3.client('s3')
for record in event['Records']:
filename = record['s3']['object']['key']
filesize = record['s3']['object']['size']
source = record['requestParameters']['sourceIPAddress']
eventTime = record['eventTime']
# get a handle on the bucket that holds your file
bucket = s3.Bucket(u'mine2')
# get a handle on the object you want (i.e. your file)
obj = bucket.Object(key= event[u'Records'][0][u's3'][u'object'][u'key'])
# get the object
response = obj.get()
# read the contents of the file and split it into a list of lines
lines = response[u'Body'].read().split()
# now iterate over those lines
for row in csv.DictReader(lines):
print(row)
emailcontent = emailcontent + '\n' + row
except Exception as e:
print(traceback.format_exc())
status_code = 500
body["message"] = json.dumps(e)
email_body = "File Name: " + filename + "\n" + "File Size: " + str(filesize) + "\n" + "Upload Time: " + eventTime + "\n" + "User Details: " + source + "\n" + "content of the csv file :" + emailcontent

)
print('Function execution Completed')
je ne sais pas ce que j'ai fait de mal, car la partie quand je reçois juste des informations sur le fichier fonctionne bien, c'est quand j'ajoute la partie lecture que la fonction lambda ne renvoie rien
Je suggère d'ajouter à votre politique IAM également l'accès à Cloudwatch. En fait, votre fonction lambda ne renvoie rien, mais vous pouvez voir votre sortie de journal dans Cloudwatch. Je recommande vraiment d'utiliser logger.info(message)
au lieu de print
lorsque vous configurez logger
.
J'espère que cela aide à déboguer votre fonction.
Hormis la partie d'envoi, voici comment je vais le réécrire (juste testé dans la console AWS):
import logging
import boto3
logger = logging.getLogger()
logger.setLevel(logging.INFO)
s3 = boto3.client('s3')
def lambda_handler(event, context):
email_content = ''
# retrieve bucket name and file_key from the S3 event
bucket_name = event['Records'][0]['s3']['bucket']['name']
file_key = event['Records'][0]['s3']['object']['key']
logger.info('Reading {} from {}'.format(file_key, bucket_name))
# get the object
obj = s3.get_object(Bucket=bucket_name, Key=file_key)
# get lines inside the csv
lines = obj['Body'].read().split(b'\n')
for r in lines:
logger.info(r.decode())
email_content = email_content + '\n' + r.decode()
logger.info(email_content)
