ob混淆

 

 jsfuck 比如说对于一些jsfuck你放在控制台输出报错的，你直接点击报错信息，就能看到jsfuck的源码

可以看到这段代码就是这个

 针对于如果jsfuck不报错的

可以在最后的括号里随便添加个字符串，让它报错

像这样

或者用脚本

(function() {
if (window.cr_eval) return
window.cr_eval = window.eval
var myeval = function (src) {
console.log("================ eval begin: length=" + src.length + ",caller=" + (myeval.caller && myeval.caller.name) + "===============")
console.log(src);
console.log("================ eval end ================")
return window.cr_eval(src)
}
var _myeval = myeval.bind(null) // 注意：这句和下一句就是小花招本招了！
_myeval.toString = window.cr_eval.toString
Object.defineProperty(window, 'eval', { value: _myeval })
console.log(">>>>>>>>>>>>>> eval injected: " + document.location + " <<<<<<<<<<<<<<<<<<<")
})();

前面是固定的额，后面加上jsfuck就行了，这么操作

还有一些表情包加密

也是老样子，放到控制台。不报错的话，删掉一个表情就行了

http://www.python-spider.com/challenge/16

 我们复制表情

 点报错信息。就出来了
