Anti-WebSpider：Web端反爬技术方案
反爬技术方案的研究与落地
一个在线教育的平台，译文的数据很重要吧，但被别人通过爬虫技术全部爬走了，那结果就是“凉凉”。再比说有个独立开发者想抄袭你的产品，通过抓包和爬虫手段将你核心的数据拿走，然后短期内做个网站和App，短期内成为你的劲敌。成果：segmentfault上发表过，获胜赞148。
大前端时代安全性如何做
如果想了解大前端（Web，App，接口）区域的安全性，可以查看我的介绍。
爬虫工程师的爬虫手段
从渲染好的html页面直接找到感兴趣的副本，然后获取对应的文本
去分析对应的接口数据，更加方便，精确地获取数据
制定出网站端反爬技术方案
本人从这2个角度（网页所见非所得，查接口请求没用）出发，制定了下面的反爬方案。
使用HTTPS协议
单位暂停限制掉请求次数过多，则封锁该账号
前端技术限制（接下来是核心技术）
例如需要正确显示的数据为“ 19950220”
先按照自己的需求利用相应的规则（数字乱序映射，正常正常的0对应还是0，但是乱序就是0 <-> 1，1 <-> 9,3 <-> 8，...）制作自定义字体（ttf）
根据上面的乱序映射规律，求得到需要返回的数据1995022
