I have a bucket for my organization in Amazon S3 which looks like
I have a Java application that can connect to Amazon S3 with the credentials and can connect to S3, create, read files
I have a requirement where a application reads the data from Python from same bucket. So I am using boto for this.
I do the following in oder to get the bucket
>>> import boto >>> from boto.s3.connection import S3Connection >>> from boto.s3.key import Key >>> >>> conn = S3Connection('xxxxxxxxxxx', 'yyyyyyyyyyyyyyyyyyyyyy') >>> conn S3Connection:s3.amazonaws.com
Now when I try to get bucket I see error
>>> b = conn.get_bucket('mydev.myorg') Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/Library/Python/2.7/site-packages/boto/s3/connection.py", line 389, in get_bucket bucket.get_all_keys(headers, maxkeys=0) File "/Library/Python/2.7/site-packages/boto/s3/bucket.py", line 367, in get_all_keys '', headers, **params) File "/Library/Python/2.7/site-packages/boto/s3/bucket.py", line 334, in _get_all response.status, response.reason, body) boto.exception.S3ResponseError: S3ResponseError: 403 Forbidden <?xml version="1.0" encoding="UTF-8"?> <Error><Code>AccessDenied</Code><Message>Access Denied</Message><RequestId>EEC05E43AF3E00F3</RequestId><HostId>v7HHmhJaLLQJZYkZ7sL4nqvJDS9yfrhfKQCgh4i8Tx+QsxKaub50OPiYrh3JjQbJ</HostId></Error>
But from the Java application everything seems to work.
Am I doing anything wrong here?
Giving the user a "stronger role" is not the correct solution. This is simply a problem with
boto library usage. Clearly, you don't need extra permissions when using Java S3 library.
Correct way to use boto in this case is:
b = conn.get_bucket('my-bucket', validate=False) k = b.get_key('my/cool/object.txt') # will send HEAD request to S3 ...
boto by default (which is a mistake on their part IMHO), assumes you want to interact with S3 bucket. Granted, sometimes you do want that, but then you should use credentials that have permissions for S3 bucket operations. But a more popular use case is to interact with S3 objects, and in this case you don't need any special bucket-level permissions, hence the use of

Clearly, you don't need extra� Python: Amazon S3 cannot get the bucket: says 403 Forbidden However, it seems I may be having a different problem (e.g., clock skew is not an issue and I already tried setting validate=False , and I believe I have the correct key and secret key because trying a bogus key or secret key gives me different errors).
After giving my "User" much stronger role, this error was gone. Means User given the permission to get_bucket

A button that says 'Get it on, Google Play', and if clicked� By default, boto will attempt to validate the bucket when you call get_bucket by performing a HEAD request on the bucket. You may not have permission to do this even though you may have permission to retrieve objects from the bucket. Try this to disable the validation step: bucket = conn.get_bucket(bucket_name, validate=False)
Read files from Amazon S3 bucket using Python
import boto3 import csv # get a handle on s3 session = boto3.Session( aws_access_key_id='XXXXXXXXXXXXXXXXXXXXXXX', aws_secret_access_key='XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX', region_name='XXXXXXXXXX') s3 = session.resource('s3') # get a handle on the bucket that holds your file bucket = s3.Bucket('bucket name') # example: energy_market_procesing # get a handle on the object you want (i.e. your file) obj = bucket.Object(key='file to read') # example: market/zone1/data.csv # get the object response = obj.get() # read the contents of the file lines = response['Body'].read() # saving the file data in a new file test.csv with open('test.csv', 'wb') as file: file.write(lines)

- This is not an answer. It is a comment. It should have be an edit to the question or a comment on the question.
- @LegoStormtroopr, you really should be more careful before leaving these kinds of comments on an answer... daydreamer is the question author.
- @BrunoBronosky, you should also be careful leaving these comments. Question authors are entirely allowed to provide answers to their own questions.
- @daydreamer, in future, please leave more useful answers to your questions, or instead simply add a summary edit to your question to highlight your solution... this would stop over keen users from mistakenly leaving these kinds of comments on your answers.
- 3 years and this answer still has 0 votes. I'm going to stand by this being a comment not an answer. More specifically an answer would say what permissions were changed rather than "much stronger role". But then it would still be the wrong solution (for cases where you can control the code). The highest voted answer is the right solution (given the same caveats) because it works around the unexpected behavior in boto.
