The most basic operation is that of issuing a new token. 最基本的一种操作是发出新令牌。
Every edit operation must be accompanied by a token, which ensures the validity of the user request and protects against CSRF attacks. 每个编辑操作必须伴有一个令牌,这可确保用户请求的有效性,并抵御CSRF攻击。
In order to realize the simulation for the whole process of operation, maintenance and support, we built a reliability model of complex repairable system by using Petri Nets. In this model, the status of each composed unit is controlled by the tokens 'movement. 为了在复杂可修复系统的可靠性模型中引入修复过程,实现系统使用维修保障全过程仿真,使用Petri网建立了一种可修复系统的可靠性模型,通过模型内部token的移动控制系统组成单元的状态。
