如何从URL中检查文件是否存在

pip install requests

import requests

def check_file_exists(url):
    response = requests.head(url, allow_redirects=True)
    if response.status_code == 200:
        return True
    else:
        return False

url = "https://example.com/path/to/file.txt"
if check_file_exists(url):
    print("文件存在")
else:
    print("文件不存在")
