import boto3
client = boto3.client('cloudfront')
These are the available methods:
Paginators are available on a client instance via the get_paginator
method. For more detailed instructions and examples on the usage of paginators, see the paginators user guide.
The available paginators are:
Waiters are available on a client instance via the get_waiter
method. For more detailed instructions and examples on the usage or waiters, see the waiters user guide.
The available waiters are:
The following example shows how to generate a signed URL for Amazon CloudFront.
Note that you will need the cryptography
library 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)
