给爬到的照片按照片超链接网址进行重命名

for webs in list:
    file_name = webs
    for url in urls1:
        time.sleep(0.5)
        print(f'下载{file_name}')
        response = requests.get(url, headers=headers)
        with open(dir_name + '/' + file_name,'wb') as f:
            f.write(response.content)

报错为
OSError: [Errno 22] Invalid argument
