前言

最近在做一个APP，需要获取我们学校——武汉纺织大学皇家停水断电断网高校的教务系统信息进行排课，无赖学校屏蔽了正方教务系统的默认登录页面，无法使用现有的接口，使用火狐抓包，发现学校自定义的登录页面用户名和密码都是明文传输，喜出望外使用HttpClient模拟登录，但是一直显示400错误，参考了CSDN和博客园的很多资料还是无解，最后只能推到，从头开始，终于发现了该死的5次GET才能获取真实的Cookies的奇葩设定（点名批评纺大教务系统，用户名密码明文存储居然登录搞那么复杂）

废话不多说，开始一步步超详细的分析爬取教务系统吧

---

分析

打开学校教务系统登录页面，先请求生成一个Cookies，用于POST使用

手动登录，可以看到，有5个302状态的请求，其中POST为发送登录数据，可以看到username和password分别是用户名，密码，execution和rmshown分别是第几次访问的标记，都不用管，但是有一个lt，经过查找发现lt是登录页面的内嵌字段，可以直接从登录页面获取，单独分析各个请求；

第一次POST用登录页面的Cookies获取iPlanetDirectoryPro，以及重定向的

Location

http://jwglxt.wtu.edu.cn/sso/j…dPM5vmJu1586512656377-w6Ia-cas

第二个302是GET，可以看到用iPlanetDirectoryPro可以来到JSESSIONID以及下一个GET的URI

Location

http://jwglxt.wtu.edu.cn/sso/j…1882D5B308262624B9BF5D5181B1D0

需要注意的是这个URI和Cookies都不是最终的，JSESSIONID只是中间Cookies用来验证其他GET

可以看到在一个GET用刚刚拿到的Cookies，获取一个重定向页面

Location

http://jwglxt.wtu.edu.cn/ticke…2928F9906338285585624192011C17

很明显，这是下一个GET的地址

GET上一步拿到的URI，终于拿到了最终的Cookies，但同时还有一个Location，你也许想这样可以跳过去直接到主页，但是不行，还是需要get它，这样才能获取动态的登录后页面，因为之后课表等信息都需要主页的来源地址，不允许直接跳转，否则会报400错误；

Location

/xtgl/login_slogin.html

注意，这是一个相对路径，需要加上前缀http://jwglxt.wtu.edu.cn

使用最终iPlanetDirectoryPro和JSESSIONID继续GET上次获得的路径，终于拿到了最终页面地址

（同样也是相对地址）

使用最终的URI和Cookies请求，终于拿到了登陆后的页面

打开课表测试一下，拿到了课表，说明成功

查看请求发现是POST，用到了最终的URI和Cookies

以上登录的原理都分析完毕，开始代码实际操作

 

代码实现

第一次GET

使用GET解析登录页面，获取初始的Cookies和LT

GetMethod getMethod = new GetMethod(url);
        //发送get
        httpClient.executeMethod(getMethod);
        //获取get的内容
        InputStream inputStream = getMethod.getResponseBodyAsStream();
        StringBuilder output = new StringBuilder();
        InputStreamReader inputStreamReader = new InputStreamReader(inputStream, "UTF-8");
        BufferedReader reader = new BufferedReader(inputStreamReader);
        String line = reader.readLine();
        while (line != null) {
            output.append(line);
            line = reader.readLine();
        }
        //解析为文档树
        Document document = Jsoup.parseBodyFragment(output.toString());
        Element body = document.body();
        //找到lt
        lt = body.select("[name=lt]").attr("value");
        System.out.println("lt: " + lt);
        //释放链接
        getMethod.releaseConnection();
        //状态码
        int statusCodeGet1 = getMethod.getStatusCode();
        System.out.println("Status code get1 :" + statusCodeGet1);
        //得到Cookies
        JSESSION = getMethod.getResponseHeader("Set-Cookie").getValue().trim().split(";")[0].split(",")[1].trim().split("=")[1];
        System.out.println("Cookies GET1 Jsession:" + JSESSION);
        ROUTE = getMethod.getResponseHeader("Set-Cookie").getValue().trim().split(";")[0].split(",")[0].trim().split("=")[1];
        System.out.println("Cookies GET1 Route:" + ROUTE);

POST登录

传输登录信息并且获取1/2的Cookies以及一个URI

String geturi2 = null;
        String loURI = "https://auth.wtu.edu.cn/authserver/login;jsessionid=";
        loURI += JSESSION;
        loURI += "?service=http%3A%2F%2Fjwglxt.wtu.edu.cn%2Fsso%2Fjziotlogin";
 PostMethod postMethod = new PostMethod(murl);
            //请求头
            postMethod.setRequestHeader("Accept", "text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8");
            postMethod.setRequestHeader("Accept-Encoding", "gzip, deflate, br");
            postMethod.setRequestHeader("Accept-Language", "zh-CN,zh;q=0.8,zh-TW;q=0.7,zh-HK;q=0.5,en-US;q=0.3,en;q=0.2");
            postMethod.setRequestHeader("Connection", "keep-alive");
            postMethod.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
            postMethod.setRequestHeader("Cookie", "route=" + ROUTE + "; JSESSIONID_auth=" + JSESSION);
            postMethod.setRequestHeader("Host", "auth.wtu.edu.cn");
            postMethod.setRequestHeader("Origin", "https://auth.wtu.edu.cn");
            postMethod.setRequestHeader("Referer", url);
            postMethod.setRequestHeader("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:74.0) Gecko/20100101 Firefox/74.0");
            //参数
            postMethod.addParameter(new NameValuePair("username", usernam));
            postMethod.addParameter(new NameValuePair("password", password));
            postMethod.addParameter(new NameValuePair("lt", lt));
            postMethod.addParameter(new NameValuePair("dllt", "userNamePasswordLogin"));
            postMethod.addParameter(new NameValuePair("execution", "e1s1"));
            postMethod.addParameter(new NameValuePair("_eventId", "submit"));
            postMethod.addParameter(new NameValuePair("rmShown", "1"));
            mClient.executeMethod(postMethod);
 //状态码
        int statusCodePost = postMethod.getStatusCode();
        System.out.println("Status code post :" + statusCodePost);
        //拿到第二步Get网址
        geturi2 = postMethod.getResponseHeader("Location").toString().split(" ")[1];
        System.out.println("Get Uri 2:" + geturi2);
        //拿到iPlanetDirectoryPro
        Header[] headers = postMethod.getResponseHeaders("Set-Cookie");
        iPlanetDirectoryPro = headers[2].getValue().split(";")[0];
        System.out.println("iPlanetDirectoryPro: " + iPlanetDirectoryPro);

第二次Get

获取中间Cookies和一小步的URI

String geturi3 = null;
        String JSESSIONID2 = null;
        //第二次GET请求进入登录界面,拿到第二个JSESSIONID_iPlanetDirectoryPro
        GetMethod getMethod2 = new GetMethod(geturi2);
        getMethod2.addRequestHeader(new Header("Cookie", iPlanetDirectoryPro));
        getMethod2.setFollowRedirects(false);//不自动处理重定向
        int statusCodeGet2 = httpClient.executeMethod(getMethod2);//状态码
        System.out.println("Status code get2 :" + statusCodeGet2);
        //得到重定向网址
        geturi3 = getMethod2.getResponseHeader("Location").toString();
        geturi3 = geturi3.replaceAll(" ", "");//去掉空格
        geturi3 = geturi3.split(":", 2)[1];//得到网址
        System.out.println("Get Uri 3 :" + geturi3);
        //得到set-Cookie 拿到JSESSIONID2
        Header[] headers2 = getMethod2.getResponseHeaders("Set-Cookie");
        JSESSIONID2 = headers2[0].getValue().split(";")[0];
        System.out.println("JSESSIONID2: " + JSESSIONID2);

第三次GET

获取最终cookies的URI地址

 String geturi4 = null;
        GetMethod getMethod3 = new GetMethod(geturi3);
        getMethod3.setFollowRedirects(false);
        getMethod3.addRequestHeader(new Header("Cookie", JSESSIONID2));
        int statusCodeGet3 = httpClient.executeMethod(getMethod3);
        System.out.println("Status code get3:" + statusCodeGet3);
        //获取下一步URI
        geturi4 = getMethod3.getResponseHeader("Location").toString();
        geturi4 = geturi4.replaceAll(" ", "");//去掉空格
        geturi4 = geturi4.split(":", 2)[1];//得到网址
        System.out.println("Get Uri 4:" + geturi4);

第四次GET

获取最终Cookies和下一步URI

String geturi5 = "http://jwglxt.wtu.edu.cn";
        GetMethod getMethod4 = new GetMethod(geturi4);
        getMethod4.setFollowRedirects(false);
        getMethod4.addRequestHeader(new Header("Cookie", iPlanetDirectoryPro));
        //状态和执行
        int statusCodeGet4 = httpClient.executeMethod(getMethod4);
        System.out.println("Status code get4:" + statusCodeGet4);
        //获取下一步URI
        String get4xd;//设置临时变量，相对URI
        get4xd = getMethod4.getResponseHeader("Location").toString();
        get4xd = get4xd.replaceAll(" ", "");//去掉空格
        get4xd = get4xd.split(":", 2)[1];//得到网址
        //拼接真实URI
        geturi5 += get4xd;
        System.out.println("Get Uri 5:" + geturi5);
        //得到set-Cookie 拿到真实
        Header[] headers3 = getMethod2.getResponseHeaders("Set-Cookie");
        JSESSION = headers3[0].getValue().split(";")[0];
        System.out.println("JSESSIONID: " + JSESSION);

第五次GET

获取登录后的页面

  GetMethod getMethod5 = new GetMethod(geturi5);
        getMethod5.setFollowRedirects(false);
        //设置Cookie
        getMethod5.addRequestHeader(new Header("Cookie", iPlanetDirectoryPro + ";" + JSESSION));
        //状态和执行
        int statusCodeGet5 = httpClient.executeMethod(getMethod5);
        System.out.println("Status code get5:" + statusCodeGet5);
        //获取下一步URI
        String get5xd;//设置临时变量，相对URI
        get5xd = getMethod5.getResponseHeader("Location").toString();
        get5xd = get5xd.replaceAll(" ", "");//去掉空格
        get5xd = get5xd.split(":", 2)[1];//得到网址
        //拼接真实URI
        loginuri += get5xd;
        System.out.println("Loginuri :" + loginuri);

 

测试

之前已经获取了所有的Cookies和最终的URI，现在就可以抓取教务系统，畅通无阻了，那么先测试一下登陆后的主页

GetMethod getMethodLog = new GetMethod(loginuri);
        getMethodLog.addRequestHeader(new Header("Cookie", iPlanetDirectoryPro + ";" + JSESSION));
        //状态和执行
        int statusCodelog = httpClient.executeMethod(getMethodLog);
        System.out.println("Status code log:" + statusCodelog);
        String result = getMethodLog.getResponseBodyAsString();
        System.out.println("最终结果：\n"+result);

测试爬取课表信息，由之前分析可以知道，这是一个POST

 String kcb = "http://jwglxt.wtu.edu.cn/kbcx/xskbcx_cxXsKb.html?gnmkdm=N253508";
PostMethod postMethod = new PostMethod(tourl);
            //请求头
            postMethod.setRequestHeader("Accept", "*/*");
            postMethod.setRequestHeader("Accept-Encoding", "gzip, deflate, br");
            postMethod.setRequestHeader("Accept-Language", "zh-CN,zh;q=0.8,zh-TW;q=0.7,zh-HK;q=0.5,en-US;q=0.3,en;q=0.2");
            postMethod.setRequestHeader("Connection", "keep-alive");
            postMethod.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
            postMethod.setRequestHeader("Cookie", Cookies);
            postMethod.setRequestHeader("Host", "auth.wtu.edu.cn");
            postMethod.setRequestHeader("Origin", "https://auth.wtu.edu.cn");
            postMethod.setRequestHeader("Referer", "http://jwglxt.wtu.edu.cn/kbcx/xskbcx_cxXskbcxIndex.html?gnmkdm=N253508&layout=default&su=" + usernam);
            postMethod.setRequestHeader("User-Agent", "Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:74.0) Gecko/20100101 Firefox/74.0");
            postMethod.setRequestHeader("X-Requested-With", "XMLHttpRequest");
            //表单数据
            postMethod.addParameter("xnm", "2019");
            postMethod.addParameter("xqm", "12");
            postMethod.setParameter(HttpMethodParams.HTTP_CONTENT_CHARSET, "utf-8");

            mClient.executeMethod(postMethod);
 int kcbcode = postMethodkcb.getStatusCode();
        System.out.println("Status code kcb :" + kcbcode);
        String ss=new String(postMethodkcb.getResponseBody(), Charset.forName("ASCII"));
        System.out.println(ss);

        //读取json
        InputStream in = postMethodkcb.getResponseBodyAsStream();
        BufferedReader br = new BufferedReader(new InputStreamReader(in,"ISO-8859-1"));
        String tempbf;
        StringBuffer html = new StringBuffer(8*1024);
        while ((tempbf = br.readLine()) != null) {
            html.append(tempbf +"\n");
        }
        System.out.println(html);

 

我们来看看结果：——

OK，可以看到数据已经全部出来了，那么获取有用的数据就和之前抓取LT一样直接在页面上查找就行，一切大功告成、

最后因为POST太长了，看起来不美观，将两个POST封装到来一个内部类中，完整代码如下，可以试一试爬取你们学校的教务系统哦！
