boto3:生成通配符CloudFront预签名URL

import boto3
from datetime import datetime, timedelta

cloudfront_client = boto3.client('cloudfront')

key_pair_id = '<Your_CloudFront_Key_Pair_ID>'
private_key_path = '<Path_to_your_private_key>'

def generate_wildcard_presigned_url(cloudfront_distribution_id, resource_path, expires_in_minutes):
    end_time = datetime.now() + timedelta(minutes=expires_in_minutes)
    signed_url = cloudfront_client.sign_url(
        url=f'https://{cloudfront_distribution_id}.cloudfront.net/{resource_path}',
        expires=end_time.timestamp(),
        key_pair_id=key_pair_id,
        private_key=open(private_key_path, 'r').read()
    )
    return signed_url

# 示例用法
distribution_id = '<Your_CloudFront_Distribution_ID>'
resource = '/*'  # 通配符(*)用于匹配所有资源路径
expiration_minutes = 60  # URL的有效期为60分钟

presigned_url = generate_wildcard_presigned_url(distribution_id, resource, expiration_minutes)
print(presigned_url)
