Saya membuat paket penerapan python AWS Lambda. Saya menggunakan satu permintaan ketergantungan eksternal. Saya menginstal ketergantungan eksternal menggunakan dokumentasi AWS http://docs.aws.amazon.com/lambda/latest/dg/lambda-python-how-to-create-deployment-package.html . Di bawah ini adalah kode python saya.
import requests
print('Loading function')
s3 = boto3.client('s3')
def lambda_handler(event, context):
#print("Received event: " + json.dumps(event, indent=2))
# Get the object from the event and show its content type
bucket = event['Records'][0]['s3']['bucket']['name']
key = urllib.unquote_plus(event['Records'][0]['s3']['object']['key']).decode('utf8')
try:
response = s3.get_object(Bucket=bucket, Key=key)
s3.download_file(bucket,key, '/tmp/data.txt')
lines = [line.rstrip('\n') for line in open('/tmp/data.txt')]
for line in lines:
col=line.split(',')
print(col[5],col[6])
print("CONTENT TYPE: " + response['ContentType'])
return response['ContentType']
except Exception as e:
print(e)
print('Error getting object {} from bucket {}. Make sure they exist and your bucket is in the same region as this function.'.format(key, bucket))
raise e
Membuat Zip konten direktori project-dir dan diunggah ke lambda (Zip konten direktori, bukan direktori). Ketika saya menjalankan fungsi, saya mendapatkan kesalahan yang disebutkan di bawah ini.

Mohon bantu saya untuk men-debug kesalahan tersebut.
import lambda_functionyang tidak ditemukan. Mungkin kamu maufrom future import lambda_function? Atau cukup pip install lambda_function pada baris cmd.
