[讨论]PHP积分下载问题
我用PHP建了个站,下载文件需要扣除账号里的费用,现在碰到一个棘手问题。
用迅雷进行第一次下载以后,会员把迅雷里的地址发给其他人,其他人也可以下载,付费下载变成免费了。
有没有达人开发过类似系统,有什么好的解决方法?
------解决方案--------------------
会员提交一个URL,希望下载,迅雷把URL和USER入库。
其他人请求同一个URL,迅雷查到URL已经被某个USER会员用过,于是决定免费给你提供下载,立即开始返回资源。
------解决方案--------------------
数据库存储一下。下载前检查此用户是否下载过。
------解决方案--------------------
你都把真实地址给了用户,当然就无所谓积分下载了
你需要始终都通过php完成下载,你搜索 php断点续传 就能得到解决方案
------解决方案--------------------
不要跳转到真实的文件地址啊,,用readfile输出文件内容,,注意输出前发送相关的报头~
