1. Session 基于Cookie做用户验证时:敏感信息不适合放在cookie中 a. Session原理 Cookie是保存在用户浏览器端的键值对 Session是保存在服务器端的键值对 b. Cookie和Session对比 c. Session配置(缺少cache) d. 示例:实现两周自动登陆 - request.session.set_expiry(60*10) - SESSION_SAVE_EVERY_REQUEST = True PS: cookie中不设置超时时间,则表示关闭浏览器自动清除 - session依赖于cookie - 服务器session request.session.get() request.session[x] = x request.session.clear() - 配置文件中设置默认操作(通用配置): SESSION_COOKIE_NAME = "sessionid" # Session的cookie保存在浏览器上时的key,即:sessionid=随机字符串(默认) SESSION_COOKIE_PATH = "/" # Session的cookie保存的路径(默认) SESSION_COOKIE_DOMAIN = None # Session的cookie保存的域名(默认) SESSION_COOKIE_SECURE = False # 是否Https传输cookie(默认) SESSION_COOKIE_HTTPONLY = True # 是否Session的cookie只支持http传输(默认) SESSION_COOKIE_AGE = 1209600 # Session的cookie失效日期(2周)(默认) SESSION_EXPIRE_AT_BROWSER_CLOSE = False # 是否关闭浏览器使得Session过期(默认) # set_cookie('k',123) SESSION_SAVE_EVERY_REQUEST = False # 是否每次请求都保存Session,默认修改之后才保存(默认)
