问题 Email providers like Gmail,yahoo,hotmail do not load images in the email directly. These services require you to allow the images to be laoded. Why do they do this?

Spammers can figure out whether their "marketing" campaigns have had any impact or not. CSRF For CSRF to work, the victim has to click a link or visit the

Spring Security :HTTP Status 403-Invalid CSRF Token 'null' was found on the request parameter '_csrf' or header 'X-CSRF-TOKEN'. 原因: 1.Spring Security 4.0之后,引入了CSRF,默认是开启。CSRF默认支持的方法: GET|HEAD|TRACE|OPTIONS,不支持POST。 Spring Security 3默认关闭csrf,Spring Security 4默认启动了csrf。 2.什么是csrf: 这是一个web应用安全的问题,CSRF(Cross-site request forgery跨站请求伪造,也被称为“One Click Attack” 或者Session Riding,攻击方通过伪造用户请求访问受信任站点。 我们知道,客户端与服务端在基于http协议在交互的数据的时候,由于http协议本身是无状态协议,后来引进了cookie的 方式进行记录服务端和客户端的之间交互的状态和标记。cookie里面一般会放置服务端生成的session id(会话ID)用来识别客户端访问服务端过 程中的客户端的身份标记。 在 跨域 (科普一下:同一个ip、同一个网络协议、同一个端口,三者都满足就是同一个域,否则就有跨域问题) 的情况下,

django中间件

一、什么是中间件 中间件顾名思义,是 介于request与response处理之间的一道处理过程 ,相对比较轻量级,并且在全局上改变django的输入与输出。因为改变的是全局,所以需要谨慎实用,用不好会影响到性能 django中间价官网定义: Middleware is a framework of hooks into Django’s request/response processing. It’s a light, low-level “plugin” system for globally altering Django’s input or output. 中间件位于web服务端与url路由层之间 二、中间件有什么用 如果你想修改请求,例如被传送到view中的 HttpRequest 对象。 或者你想修改view返回的 HttpResponse 对象,这些都可以通过中间件来实现。 可能你还想在view执行之前做一些操作,这种情况就可以用 middleware来实现。 Django默认的中间件:(在django项目的settings模块中,有一个 MIDDLEWARE_CLASSES 变量,其中每一个元素就是一个中间件,如下图) MIDDLEWARE = [ 'django.middleware.security.SecurityMiddleware', 'django
