I am trying to upload an image to S3 through Python. My code looks like this:
from PIL import Image
from boto.s3.key import Key
def upload_to_s3(aws_access_key_id, aws_secret_access_key, file, bucket, key, callback=None, md5=None, reduced_redundancy=False, content_type=None):
conn = boto.connect_s3(aws_access_key_id, aws_secret_access_key)
bucket = conn.get_bucket(bucket, validate=False)
k = Key(bucket)
k.key = key
AWS_ACCESS_KEY = "...."
AWS_ACCESS_SECRET_KEY = "....."
filename = "images/image_0.jpg"
file = Image.open(filename)
key = "image"
bucket = 'images'
upload_to_s3(AWS_ACCESS_KEY, AWS_ACCESS_SECRET_KEY, file, bucket, key)
I am getting this error message:
S3ResponseError: S3ResponseError: 400 Bad Request
This code is based on the tutorial from this website: http://stackabuse.com/example-upload-a-file-to-aws-s3/
I have tried k.set_contents_from_file as well as k.set_contents_from_filename, but both don’t seem to work for me.
The error says something about using AWS4-HMAC-SHA256, but I am not sure how to do that. Is there another way to solve this problem besides using AWS4-HMAC-SHA256? If anyone can help me out, I would really appreciate it.
client = boto3.client('s3', region_name='us-west-2')
client.upload_file('images/image_0.jpg', 'mybucket', 'image_0.jpg')
Try to avoid putting your credentials in the code. Instead:
- If you are running the code from an Amazon EC2 instance, simply assign an IAM Role to the instance with appropriate permissions. The credentials will automatically be used.
- If you are running the code on your own computer, use the AWS Command-Line Interface (CLI)
aws configurecommand to store your credentials in a file, which will be automatically used by your code.
