Generate a signed URL for Amazon CloudFront
|
|
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
The following example shows how to generate a signed URL for Amazon CloudFront.
|
|
Note that you will need the ``cryptography`` `library <https://cryptography.io/en/latest/>`__ to follow this example::
|
|
|
|
import datetime
|
|
|
|
from cryptography.hazmat.backends import default_backend
|
|
from cryptography.hazmat.primitives import hashes
|
|
from cryptography.hazmat.primitives import serialization
|
|
from cryptography.hazmat.primitives.asymmetric import padding
|
|
from botocore.signers import CloudFrontSigner
|
|
|
|
|
|
def rsa_signer(message):
|
|
with open('path/to/key.pem', 'rb') as key_file:
|
|
private_key = serialization.load_pem_private_key(
|
|
key_file.read(),
|
|
password=None,
|
|
backend=default_backend()
|
|
)
|
|
return private_key.sign(message, padding.PKCS1v15(), hashes.SHA1())
|
|
|
|
key_id = 'AKIAIOSFODNN7EXAMPLE'
|
|
url = 'http://d2949o5mkkp72v.cloudfront.net/hello.txt'
|
|
expire_date = datetime.datetime(2017, 1, 1)
|
|
|
|
cloudfront_signer = CloudFrontSigner(key_id, rsa_signer)
|
|
|
|
# Create a signed url that will be valid until the specific expiry date
|
|
# provided using a canned policy.
|
|
signed_url = cloudfront_signer.generate_presigned_url(
|
|
url, date_less_than=expire_date)
|
|
print(signed_url)
