searchword = request.args.get('key','') We recommend accessing URL parameters with get or by catching theKeyErrorbecause users might change the URL and presenting them a 400 bad request page in that case is not user friendly. 我们建议使用 get 或捕获 KeyError 来访问 URL 参数,因为用户可能会...
If a secret key is set, cryptographic components can use this to sign cookies and other things. Set this to a complex random value when you want to use the secure cookie for instance. This attribute can also be configured from the config with the SECRET_KEY configuration key. Defaults to ...
也就是说,利用模板引擎来生成前端的html代码,模板引擎会提供一套生成html代码的程序,然后只需要获取用户的数据,然后放到渲染函数里,然后生成模板+用户数据的前端html页面,然后反馈给浏览器,呈现在用户面前。 但是新的模板引擎往往会有一些安全问题 , 即使大部分模板引擎有提供沙箱隔离机制 , 但同样存在沙箱逃逸技术来绕...

A secret key should be as random as possible. Your operating system has ways to generate pretty random data based on a cryptographic random generator. Use the following command to quickly generate a value forFlask.secret_key(orSECRET_KEY): ...
如果是记住我的功能,需要在cookie中单独设置一个字段来记录状态,其中cookie_name 为设置的字段名称,duration为设置的有效时间(默认值是365天)以及域名,路径等等的参数,其中data 是由encode_cookie 生成,encode_cookie我就不在跳进去了,这就说下生成数据的组成部分,生成后的数据分为两个部分 id| hmac(SECRET_KEY ,...
注意:Flask的session是以cookie为基础,但是是在Server端使用secret key并使用AES之类的对称加密算法进行加密的,然后将加密后的cookie发送给客户端。由于是加密后的数据,客户端无法篡改数据,也无法获知session中的信息,只能保存该session信息,在之后的请求中携带该session信息 ...
