本预防类最大的优点是对于最终用户来说透明，用户几乎感觉不到预防类的存在。而对于机器人或类似的自动化程序来说，需要获取页面的SID，然后根据SID计算及拼写，最后将正常的数据与根据SID计算出来的结果一并提交至处理页面进行验证。



破解本预防类的最大难点在于如何解释执行javascr ipt脚本。因为本类将动态加载部分使用javascr ipt形式由客户端浏览器解释执行，但机器人只认识源代码，并不能执行脚本，因此机器人在提交的时候缺少SID验证标志，导致服务器端验证失败。



除非对方专门针对本算法编写机器人程序或手工注册，否则是不允许注册的哦。

For automated robots or similar procedures, the need for page SID, and then calculated according to SID and spelling, and finally to the normal data and calculated results based on SID to be submitted to the processing page to verify.



Break the prevention of the most difficult class is how to explain the implementation of javascr ipt scr ipts. As part of the class will dynamically load the form using javascr ipt explained by the implementation of the client browser, but the robot known only to the source code, and can not execute the scr ipt, so when the robot is missing SID submitted certification mark, resulting in server-side validation fails.



Unless the other party written specifically for this algorithm the robot program, or manual registration, otherwise it is not allowed to register, oh.
