rep.set_cookie(key,value,...)
rep.set_signed_cookie(key,value,salt=‘加密盐‘,...)
    参数：
        key,              键
        value=‘‘,         值
        max_age=None,     超时时间
        expires=None,     超时时间(IE requires expires, so set it if hasn‘t been already.)
        path=‘/‘,         Cookie生效的路径，/ 表示根路径，特殊的：跟路径的cookie可以被任何url的页面访问
        domain=None,      Cookie生效的域名
        secure=False,     https传输
        httponly=False    只能http协议传输，无法被JavaScript获取（不是绝对，底层抓包可以获取到也可以被覆盖）
