如何临时存储生成的镜像以供下载

import os
from qcloud_cos import CosConfig
from qcloud_cos import CosS3Client

# 配置COS客户端
secret_id = 'your_secret_id'
secret_key = 'your_secret_key'
region = 'your_region'
config = CosConfig(Region=region, SecretId=secret_id, SecretKey=secret_key)
client = CosS3Client(config)

# 上传镜像到临时存储
def upload_image_to_temp_storage(image_path, bucket_name, key):
    response = client.upload_file(
        Bucket=bucket_name,
        LocalFilePath=image_path,
        Key=key
    )
    return response['ETag']

# 下载镜像从临时存储
def download_image_from_temp_storage(bucket_name, key, download_path):
    response = client.get_object(
        Bucket=bucket_name,
        Key=key
    )
    with open(download_path, 'wb') as f:
        f.write(response['Body'].read())

# 示例用法
image_path = '/path/to/your/image'
bucket_name = 'your_bucket_name'
key = 'your_image_key'
download_path = '/path/to/download/image'

upload_image_to_temp_storage(image_path, bucket_name, key)
download_image_from_temp_storage(bucket_name, key, download_path)
