在文本文件中查找与行匹配的文件名

import re
from qcloud_cos import CosConfig
from qcloud_cos import CosS3Client

# 配置腾讯云COS
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)

# 读取文本文件内容
with open('text_file.txt', 'r') as file:
    lines = file.readlines()

# 正则表达式模式
pattern = r'your_pattern'

# 遍历每一行进行匹配
for line in lines:
    # 匹配文件名
    match = re.search(pattern, line)
    if match:
        file_name = match.group(0)
        # 在腾讯云COS中查找文件
        response = client.list_objects(Bucket='your_bucket', Prefix=file_name)
        # 处理查找结果
        if 'Contents' in response:
            for content in response['Contents']:
                print(content['Key'])
