有一些工具是可以直接反js混淆的,比如:https://www.html.cn/tool/js_beautify/

如果用asp.net的话,怎么能做到呢?逛了论坛,有看一个哥们发过一个方法,是用:MSScriptControl
引用com组件 Microsoft Script Control 1.0


[C#] 纯文本查看 复制代码
private string Eval(string stringjs)
{
    string MyJs = "function Eval(code){code2=code.replace(/^eval/,'');return eval(code2);}";
    object[] _params = new object[1];
    _params[0] = stringjs;
    MSScriptControl.ScriptControl js = new MSScriptControl.ScriptControl();
    js.Language = "javascript";
    js.AddCode(MyJs);
    string result = js.Run("Eval", _params);//NET4.0以下为js.Run("Eval",ref _params).ToString();
    return result;
}



但是这个有bug,在x64的系统下,无法运行,然后你换成  x86的话,可以运行,但是到了这一步,就会报各种错误



就是特别多的问题,我想问下,各位大手子们,都还有什么方法呢?
