用某个字符串生成100个随机数,并且相同的字符串不同时间生成的随机数不一样

Jun 06, 2016 pm 08:40 PM
c++ lua php python

以前的流程:

1、服务端给客户端发100个随机数。
2、C++客户端随后进行用户的操作,将用户操作发送给服务端。
3、服务端能根据自己发送给客户端的随机数,和客户端传来的一些参数,重现客户端用户操作出来的结果。

希望服务端做到

1.给一个或几个字符串。客户端、服务端用一致的方法,算出100个相同的随机数。
2.不同时间,相同字符串也生成出不同的随机数。

先把字符串 连上时间戳 然后hash 再根据你要求的随机数类型 进行转换分切 就行了 但这不是随机数
这就是根据一定的算法算出来的 因为你的种子 加上了时间戳 所以不同的时间 出来的数是不同的
