使用django或任何python模块链接生成器

您可能想要做的是使用散列生成随机密钥,如md5 / sha1.存储文件和密钥,它在数据库中添加的日期时间,在您的网络服务器上可以创建下载目录,如apache或nginx …建议nginx),因为它是临时的,你需要添加一个cron检查自生成url以来的时间是否已过期的作业,清除文件并删除db条目.这应该是manage.py的django命令

请注意这是为此编写的示例代码,未经测试！它可能无法按照您计划实现此目标的方式运行,但它可行.如果你想让dl受到pw保护,那么请查看httpbasic auth.您可以在创建链接时或在注册时使用htpasswd和子进程模块在httpd.auth文件中动态生成和删除条目.
