教务系统快速抢课模块的实现（Python）
作者：互联网
今天看到小20们在抢课，想看看教务系统啥样子，emmmmmmm
一看就是，华而不实，土豆服务器，果然，到抢课的点了，服务器直接白给。卡的要死
闭着眼都知道是谁的杰作（手动滑稽）
废话不多说，开干
Section A - ASP.NET_SessionId的获取方法
了解一下ASP.NET_SessionId的相关内容，大概是，ASP.NET_SessionId是用来判断web会话状态的一个参数，只要访问过页面之后就会保存在cookies中。
了解了机制，只需要请求一下login_home.aspx即可
获取到该参数，进行下一步
登录教务系统,分析发包，发现了几个未知参数
一番寻找，如下，就在html源码中
dsdsdsds开头的这个参数，深扒了教务系统的JS代码，在第262行发现了这个函数
function chkpwd(obj) {
if (obj.value != '') {
var s = md5(document.all.txt_asmcdefsddsd.value + md5(obj.value).substring(0, 30).toUpperCase() + '10476').substring(0, 30).toUpperCase();
document.all.dsdsdsdsdxcxdfgfg.value = s;
} else {
document.all.dsdsdsdsdxcxdfgfg.value = obj.value;
}
}
function chkyzm(obj) {
if (obj.value != '') {
var s = md5(md5(obj.value.toUpperCase()).substring(0, 30).toUpperCase() + '10476').substring(0, 30).toUpperCase();
document.all.fgfggfdgtyuuyyuuckjg.value = s;
} else {
document.all.fgfggfdgtyuuyyuuckjg.value = obj.value.toUpperCase();
}
}python实现就容易了
dsdsdsdsdxcxdfgfg = md5(userID + md5(userPwd)[:30].upper() + "10000")[:30].upper()
fgfggfdgtyuuyyuuckjg = md5(md5(userYzm)[:30].upper() + "10000")[:30].upper()
#10000 是学校代码放上登录源码
session_requests = requests.session()

print("登录反馈：" + rest.string)
if rest.string == "正在加载，请稍候...":
print("登录成功!")
break
else:
print("登录失败!请重新登录....")Section B - 接下来就是选课系统了，怎么实现抢课？
先把参数放上去
经过尝试，参数的含义都放入了注释中
sel_lx = 2
sel_xq = 1
print("请输入您的校区代码（校区：1西校区，3东校区）： " + str(sel_xq)) ########################
params_getClass = {
"sel_lx" : sel_lx, #类型：0必修，2选修
"sel_xq" : sel_xq, #校区：1西校区，3东校区
"kc" : ""
}
headers_getClass = {

"Content-Length": "21",
"Cache-Control": "max-age=0",
"Upgrade-Insecure-Requests": "1",

"Accept-Encoding": "gzip, deflate",
"Accept-Language": "zh-CN,zh;q=0.9"
}打印出所有公共课的列表
rsp = session_requests.post(url_getClass, data = params_getClass, headers = headers_getClass)
soup = BeautifulSoup(rsp.text, 'html.parser')
rest = soup.find('table', {'id':'oTable'})
classValueSet = rest.find_all('input', {'type':'checkbox'})
nameSet = rest.find_all('a', {'onclick':"openWin(this,'kc')"})
classLNo = rest.find_all('input', {'type':"hidden"})
num = 0
resList = []
for cvs in classValueSet:
tmpDict = {
"name" : "",
"classValue" : "",#=|
"getValue" : "",#||||||
"classNo" : "",#chkkc50
"classLNo" : ""#chkSKBJ14
}
tmpDict["classValue"] = cvs["value"]
tmpDict["classNo"] = cvs["name"]
tmpDict["classLNo"] = classLNo[num]["name"]
tmpDict["name"] = nameSet[num].string
nameR = rest.find('a', {'onclick':"openWinDialog(this," + str(num) + ")"})
tmpDict["getValue"] = nameR["value"]
#print(tmpDict)
resList.append(tmpDict)
num += 1
allCourse = num
print("----------所选校区的所有课程如下----------")
num = 0
for tmp in resList:
print(str(num) + " --- " + tmp["name"])
num += 1
然后当点开
会发包，代码如下
while True:
your_c = input("请输入你要的课程: (输入-1退出): ")
if int(your_c) and your_c == "" < 0:
break
classData = {
"lx" : "ZX",
"id" : resList[int(your_c)]["getValue"],

}

soup = BeautifulSoup(rsp.text, 'html.parser')

restH = soup.find_all('tr', {'class':'H'})
num = 0
for tmp in range(len(restB) + len(restH)):
tmpDict = {
"time" : "",
"place" : "",
"haveNum" : "",
"teacher" : "",
"value" : ""
}
restNow = restB[int(tmp/2)]
if tmp % 2 == 1:
restNow = restH[int((tmp-1)/2)]
rtd_r = restNow.find_all("td",{"align":"right"})
rtd_l = restNow.find_all("td",{"align":"left"})
tmpDict["haveNum"] = rtd_r[2].text
tmpDict["time"] = rtd_l[1].text
tmpDict["place"] = rtd_l[2].text
tmpDict["teacher"] = restNow.find("a",{"id":"showD"}).text
tmpDict["value"] = restNow.find("input",{"type":"radio"})["value"]
print(str(tmp) + "、时间：" + tmpDict["time"].replace("\\u2002", "") + ", 地点：" + tmpDict["place"]+ ", 数量：" + tmpDict["haveNum"]+ ", 老师：" + tmpDict["teacher"])
infList.append(tmpDict)
chpt = input("请选择对应时间的课堂序号(输入-1退出): ")
if int(chpt) < 0 and chpt == "":
continue以上许多参数，都是通过html源码得到
本节投放了登录源码+查看课程源码+查看具体节数源码
具体的抢课源码，私聊详情，emmmmmm
完事大吉，祝大家期末考个好成绩，拜拜
