自动评教脚本

由于教务系统的沙雕设计，评教十分费劲，每两个按钮点击间隔需要大于1.5s，于是突发奇想搞了这个js脚本一键评教。

由于该脚本是运行在你自己浏览器里的，而且代码完全公开，所以不会对你的账号造成任何风险。

2019.12.23更新：已经修了新版教务系统API失效的问题

2020.6.14 更新：感谢Ciel大佬适配了今年的教务系统

简要使用说明

打开某一科老师的评教页面，按F12打开控制台，然后切换到Console标签，把以下代码复制进去按下回车，再把最下面的同学姓名填上就完事了。

代码如下

var list=["p01","p02","p03","p04","p05","p06","p07","p08","p09","p10","sat11","p12"],ans=["A","A","A","A","A","A","A","A","A","A","A","C"];function genNewTime(){var e=lastTime+Math.floor(1e3*(1.5*Math.random()+1.5));return lastTime=e,e}ntms.widget._AutoLabel.prototype._static.setInterval(0);for(var lastTime=(new Date).getTime()-6e4,clicks={_boot_:lastTime},i=0;i<list.length;i++)$("input[name='"+list[i]+"'][value='"+ans[i]+"']").click(),clicks[list[i]]=genNewTime();function xhrWrapper(e,t){dojo.xhrPost({url:"/ntms/service/res.do",handleAs:"json-comment-optional",headers:[],contentType:"application/json",load:function(e){t(e)},sync:!0,postData:dojo.toJson(e)})}function setUID(e){uid=e.userId,xhrWrapper({tag:"student_sch_dept",branch:"default",params:{schId:e.defRes.school,deptId:e.defRes.department,egrade:null,adcId:e.defRes.adcId}},searchName)}function searchName(e){e.value.forEach(function(e){nameList.push(e.name)}),console.log(nameList);var t=$("#puzzle_1").innerHTML,n=$("#puzzle_2").innerHTML,o=new RegExp("^"+t+"(.)"+n+"$");nameList.forEach(function(e){var t=o.exec(e);null!=t&&(console.log(t),document.getElementById("dijit_form_TextBox_0").value=t[1])})}ntms.widget._AutoLabel.prototype._static.clicks=clicks;var uid,nameList=[];dojo.xhrPost({url:"/ntms/action/getCurrentUserInfo.do",handleAs:"json-comment-optional",load:function(e){setUID(e)},sync:!0});

技术说明

该代码主要patch了ntms.widget._AutoLabel模块。先使用setInterval函数将允许的点击间隔设为0，然后用jquery的选择器选好答案。但是后面发现提交的数据里还记录了点击间隔等数据，直接提交比较危险，于是我们编造了每个按钮的点击数据，然后写入 _AutoLabel模块里，覆盖掉原本的click结果，构造出完美的请求包。

自动填写同学姓名方面，先请求 /ntms/action/getCurrentUserInfo.do 获取自己的UID，然后请求res.do，获取自己所在学院班级信息，然后通过 student_sch_dept 查询所有同班同学的名字，正则匹配 puzzle_1 和 puzzle_2 给的两半姓名，填写进去就完成了。

未压缩的源码如下：

var list = ["p01","p02","p03","p04","p05","p06","p07","p08","p09","p10","sat11","p12"];
var ans = ["A","A","A","A","A","A","A","A","A","A","A","C"];
function genNewTime(){
    var newTime = lastTime + Math.floor((Math.random() * 1.5 + 1.5) * 1000);
    lastTime = newTime;
    return newTime;
}
ntms.widget._AutoLabel.prototype._static.setInterval(0);
var lastTime = new Date().getTime() - 60000;
var clicks = {"_boot_": lastTime};
for(var i=0; i < list.length; i++){
    $("input[name='" + list[i] + "'][value='" + ans[i] + "']").click();
    clicks[list[i]] = genNewTime();
}
ntms.widget._AutoLabel.prototype._static.clicks = clicks;
