1 | # 说明
2 | 1. 教务系统登陆页地址的`(S(hpuxisy320bpi2iunqzwd445))/`下称为cookieId，是系统为了防止浏览器禁用Cookie而存在URL上的，每次都会变化，一段时间后失效。
3 |
4 | 所以sessionId需要每次登陆前获取，获取方式：Get请求[http://jwxt2.gdufe.edu.cn:8080](http://jwxt2.gdufe.edu.cn:8080)会返回302跳转，header里的`location`有跳转链接，内含sessionId，需要禁止自动跳转才能获取。
5 |
6 | 有sessionId之后登陆并用Cookie进行其他操作，全程同一个HttpClient对象会自动管理Cookie(4.x版本HttpClient)
7 |
8 | 2. 登陆前需要获取一次登陆页的`__VIEWSTATE`信息，__VIEWSTATE存储了当前视图结构，表示当前页面有什么东西，编码转换地址：[http://viewstatedecoder.azurewebsites.net/](http://viewstatedecoder.azurewebsites.net/)
9 |
10 | 3. 登陆后可以直接GET查当前学期课表、分数等，需要指定学期的话要获取当前学期课表/分数页面的__VIEWSTATE，再Post过去。
11 |
12 | 4. 登陆后基本上所有请求都含`xh=...&xm=...&gnmkdm=N121603`，xm是GBK/gb2312编码的姓名，gnmkdm固定值，这2个不是必要属性。
13 |
14 | 5. 代码中的成员变量URL均不包含学号，所以除登陆时外，`getAndSetViewState()`的url需带上学号。
15 |
16 | 6. `Base_URL`有改变的话（登陆时获取sessionId之后就改变）需要调用refreshUrlByBaseUrl()更新相关的URL。
17 |
18 | # 特殊情况
19 |
20 | 如果从课表html里正则匹配课程时不对劲，则可能是这种情况
