pyton之redis加有效时间

stop_server_key = "server_stop"

def lock(redis, key, value, expire):
    return redis.register_script(
        '''
        if redis.call("get", KEYS[1]) == 0 then
            redis.call("setnx", KEYS[1], ARGV[1])
            redis.call("expire", KEYS[1], ARGV[2])
            return 1
        else
            return 0
        end
        '''
    )(keys=[key], args=[value, expire])

lock(redis, stop_server_key, 1, 3)

简单点

 r.set(self.stop_server_key, 1,ex=3600,nx=True)
