I am trying to upload files from local directory to S3 folder. I am able to upload files to S3 bucket but I am unable to upload files to folder within S3 bucket.
Could any one help? What am i doing wrong here..
Here is the code:
import os
import sys
import boto3
import fnmatch
import pprint
import re
import hashlib
SOURCE_DIR = '/home/user/Downloads/tracks/'
BUCKET_NAME = 'mybucket'
S3_FOLDER = 'mybucket/folder1/'
client = boto3.client('s3')
s3 = boto3.resource('s3')
def get_md5(filename):
f = open(filename, 'rb')
m = hashlib.md5()
while True:
data = f.read(10240)
if len(data) == 0:
break
m.update(data)
return m.hexdigest()
def get_etag(filebase,filepath):
for item in bucket.objects.all():
keyfile = S3_FOLDER + filebase
if(keyfile == item.key):
md5 = get_md5(filepath)
etag = item.e_tag.strip('"').strip("'")
if etag != md5:
print(filebase + ": " + md5 + " != " + etag)
return(files_to_upload.append(filepath))
else:
return(files_to_upload.append(filepath))
files_to_upload = []
for root, dirnames, filenames in os.walk(SOURCE_DIR):
for filename in filenames:
filepath = os.path.join(root, filename)
get_etag(filename,filepath)
for f in files_to_upload:
client.put_object(Bucket=BUCKET_NAME, Key=f)
Folders don't really exist in S3. You can prefix the file name (object key) with the something that looks like a folder path.
It's not entirely clear to me what your code is doing with the file paths, but your code needs to be changed to something like this:
for f in files_to_upload:
key = "my/s3/folder/name/" + f
client.put_object(Bucket=BUCKET_NAME, Key=key, Body=f)
Note: You weren't passing a Body
parameter, so I think your code was just creating empty objects in S3.
