我遇到了一个用 Python 编写的简单 AWS Lambda 函数的问题。
当我运行我的 Lambda 函数时,我的代码按预期运行,结果是正确的,但仍然以错误代码(退出代码): 结束"Process exited before completing request",这导致 Lambda 运行 3 次(异步)。
您是否有任何最佳实践来管理 Lambda 的退出代码?
#!/usr/bin/python
import boto3
import sys
import tweepy
import datetime
session = boto3
# Init s3 client
s3 = session.resource('s3')
def get_data_and_push(s3_bucket, s3_key, user):
# Retrieve CSV file
try:
dest = s3.Object(s3_bucket, s3_key)
dest.download_file(tmpfile)
except Exception, e:
print 'An error occured while trying to download CSV file'
print 'This exception has been thrown :'
print e
sys.exit(1)
# Authenticate to Twitter
try:
auth = tweepy.OAuthHandler(t_consumer_key, t_consumer_secret)
auth.set_access_token(t_access_token_key, t_access_token_secret)
api = tweepy.API(auth)
except Exception, e:
print 'Cannot authenticate to Twitter.'
print 'This exception has been thrown :'
print e
sys.exit(2)
data = api.get_user(user)
print 'User : ' + data.screen_name
print 'Followers : ' + str(data.followers_count)
print 'Friends : ' + str(data.friends_count)
print '-----------'
# Get today's date
today = datetime.datetime.now().strftime("%Y-%m-%d")
# Write result
try:
# Write result at the end of the file
file = open(tmpfile, 'a')
file.write(today + ',' + str(data.followers_count) + ',' + str(data.friends_count)+ '\n')
file.close()
except Exception, e:
print 'Unable to write in temp file'
print 'This exception has been thrown :'
print e
sys.exit(5)
# Upload final file
try:
# Push file to S3
dest.upload_file(tmpfile)
except Exception, e:
print 'An error occured while trying to upload CSV file'
print 'This exception has been thrown :'
print e
sys.exit(6)
谢谢你的帮助,
