php实现模拟登陆方正教务系统抓取课表,方正课表

课程格子和超级课程表这两个应用,想必大学生都很熟悉,使用自己的学号和教务系统的密码,就可以将自己的课表导入,随时随地都可以在手机上查看。

  其实稍微了解一点php的话,我们也可以做一个类似这样的web 应用。

  1,解决掉验证码

    其实这是正方的一个小bug,当我们进入登陆界面时,浏览器会去请求服务器,服务器会生成一个验证码图片。如果我们不去请求这个图片,那么正方后台也不会生成相应的        验证码,于是这样我们就有了可乘之机,让我高兴会儿~这时,我们在不填写验证码的情况下,可以很流畅的进入。大家可以在自己的电脑上禁止访问验证码的地址,然后试试这        是不是真的~当然,这只对正方有效。

  2,php 的curl 模拟登陆

    接下来就是相关代码了,相信很多人和我一样,只喜欢看例子,对于长篇大论的讲解,转头就走……不过这个习惯还是不好……废话不多说!

//模拟登陆
  function curl_request($url,$post='',$cookie='', $returnCookie=0){
      $curl = curl_init();
      curl_setopt($curl, CURLOPT_URL, $url);
      curl_setopt($curl, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.1; Trident/6.0)');
      curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
      curl_setopt($curl, CURLOPT_AUTOREFERER, 1);
      curl_setopt($curl, CURLOPT_REFERER, "这里一定要换成教务系统登陆的url"); //填写教务系统url
      if($post) {
        curl_setopt($curl, CURLOPT_POST, 1);
        curl_setopt($curl, CURLOPT_POSTFIELDS, http_build_query($post));
      }
      if($cookie) {
        curl_setopt($curl, CURLOPT_COOKIE, $cookie);
      }
      curl_setopt($curl, CURLOPT_HEADER, $returnCookie);
      curl_setopt($curl, CURLOPT_TIMEOUT, 20);
      curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
      $data = curl_exec($curl);
      if (curl_errno($curl)) {
        return curl_error($curl);
      }
      curl_close($curl);
      if($returnCookie){
        list($header, $body) = explode("\r\n\r\n", $data, 2);
        preg_match_all("/Set\-Cookie:([^;]*);/", $header, $matches);
        $info['cookie'] = substr($matches[1][0], 1);
        $info['content'] = $body;
        return $info;
      }else{
        return $data;
      }
  }
Copy after login

  3,教务系统登陆页面的隐藏字段

    举个栗子

复制代码 代码如下:

    这些东西在登陆的时候也是需要带上的,顺便贴出函数,顺便暴漏了博主的学校……皇家种地大学(主要是正则表达式的运用)

//登陆页面的隐藏字段  

function getView(){
  $url = 'http://jw.hzau.edu.cn/default2.aspx';
  $result = curl_request($url);
  $pattern = '/<input type="hidden" name="__VIEWSTATE" value="(.*&#63;)" \/>/is';
  preg_match_all($pattern, $result, $matches);
  $res[0] = $matches[1][0];
     
  return $res[0] ;
}
  //返回教室查询页面的隐藏值
  private function getViewJs($cookie,$xh){
    $url = "http://jw.hzau.edu.cn/xxjsjy.aspx&#63;xh={$xh}";
    $result = curl_request($url,'',$cookie);
    $pattern = '/<input type="hidden" name="__VIEWSTATE" value="(.*&#63;)" \/>/is';
    preg_match_all($pattern, $result, $matches);
    $res[0] = $matches[1][0];
    return $res[0] ;
  }

Copy after login

  4,cookie 的获取

function login($xh,$pwd){
    $url = 'http://jw.hzau.edu.cn/default2.aspx';
    $post['__VIEWSTATE'] = $this->getView();
    $post['txtUserName'] = $xh; //填写学号
    $post['TextBox2'] = $pwd; //填写密码
    $post['txtSecretCode'] = '';
    $post['lbLanguage'] = '';
    $post['hidPdrs'] = '';
    $post['hidsc'] = '';
    $post['RadioButtonList1'] = iconv('utf-8', 'gb2312', '学生');
    $post['Button1'] = iconv('utf-8', 'gb2312', '登录');
    $result = curl_request($url,$post,'', 1);
    return $result['cookie'];
  }
Copy after login

  5,让我们来试试查课表的功能,格式有点乱额,大家凑合着看,我把课表转成了一个二维关联数组

//返回课表字符串
private function classresult($xh,$pwd){
    date_default_timezone_set("PRC"); //时区设置
    $classList = "";//声明课表变量
 
    $cookie = $this->login($xh,$pwd);
    $view = $this->getViewJs($cookie,$xh);//验证密码是否正确
 
    //如果密码正确
    if (!empty($view)) {
      $url = "http://jw.hzau.edu.cn/xskbcx.aspx&#63;xh={$xh}";
      $result = curl_request($url,'',$cookie); //保存的cookies
      preg_match_all('/<table id="Table1"[\w\W]*&#63;>([\w\W]*&#63;)<\/table>/',$result,$out);
      $table = $out[0][0]; //获取整个课表
 
      preg_match_all('/<td [\w\W]*&#63;>([\w\W]*&#63;)<\/td>/',$table,$out);
      $td = $out[1];
      $length = count($td);
 
      //获得课程列表
      for ($i=0; $i < $length; $i++) {
        $td[$i] = str_replace("<br>", "", $td[$i]);
 
        $reg = "/{(.*)}/";
       
        if (!preg_match_all($reg, $td[$i], $matches)) {
          unset($td[$i]);
        }
      }
 
      $td = array_values($td); //将课程列表数组重新索引
      $tdLength = count($td);
      for ($i=0; $i < $tdLength; $i++) {
        $td[$i] = iconv('GB2312','UTF-8',$td[$i]);
      }
 
      //将课表转换成数组形式
      function converttoTable($table){
        $list = array(
          'sun' => array(
            '1,2' => '',
            '3,4' => '',
            '5,6' => '',
            '7,8' => '',
            '9,10' => ''
          ),
          'mon' => array(
            '1,2' => '',
            '3,4' => '',
            '5,6' => '',
            '7,8' => '',
            '9,10' => ''
          ),
          'tues' => array(
            '1,2' => '',
            '3,4' => '',
            '5,6' => '',
            '7,8' => '',
            '9,10' => ''
          ),
          'wed' => array(
            '1,2' => '',
            '3,4' => '',
            '5,6' => '',
            '7,8' => '',
            '9,10' => ''
          ),
          'thur' => array(
            '1,2' => '',
            '3,4' => '',
            '5,6' => '',
            '7,8' => '',
            '9,10' => ''
          ),
          'fri' => array(
            '1,2' => '',
            '3,4' => '',
            '5,6' => '',
            '7,8' => '',
            '9,10' => ''
          ),
          'sat' => array(
            '1,2' => '',
            '3,4' => '',
            '5,6' => '',
            '7,8' => '',
            '9,10' => ''
          )
        );
        $week = array("sun"=>"周日","mon"=>"周一","tues"=>"周二","wed"=>"周三","thur"=>"周四","fri"=>"周五","sat"=>"周六");
        $order = array('1,2','3,4','5,6','7,8','9,10');
        foreach ($table as $key => $value) {
          $class = $value;
          foreach ($week as $key => $weekDay) {
            $pos = strpos($class,$weekDay);
            // echo $pos;
            if ($pos) {
              $weekArrayDay = $key; //获取list数组中的第一维key
              foreach ($order as $key => $orderClass) {
                $pos = strpos($class,$orderClass);
                if ($pos) {
                  $weekArrayOrder = $orderClass; //获取该课程是第几节
                  break;
                }
              }
              break;
            }
          }
          $list[$weekArrayDay][$weekArrayOrder] = $class;
        }
        return $list;
      }
           
      //调用函数
      return converttoTable($td);
    }else{
      return 0;
    }
  }
Copy after login

  6,再试试查询空教室的功能

//空教室查询结果
  public function roomresult(){
    $xh = ""; //设置学号
    $pwd = ""; //学号对应的密码
 
    $cookie = $this->login($xh,$pwd);
    $url = "http://jw.hzau.edu.cn/xs_main.aspx&#63;xh={$xh}";
    $result = curl_request($url,'',$cookie); //保存的cookies
 
    $url="http://jw.hzau.edu.cn/xxjsjy.aspx&#63;xh={$xh}";
    $post['Button2'] = iconv('utf-8', 'gb2312', '空教室查询');
    $post['__EVENTARGUMENT']='';
    $post['__EVENTTARGET']='';
    $post['__VIEWSTATE'] = $this->getViewJs($cookie,$xh);
    $post['ddlDsz'] = iconv('utf-8', 'gb2312', '单');
    $post['ddlSyXn'] = '2014-2015'; //学年
    $post['ddlSyxq'] = '1';
    $post['jslb'] = '';
    $post['xiaoq'] = '';
 
    $post['kssj']=$_GET['start']; //提交的开始查询时间 
    $post['sjd']=$_GET['class'];//提交的课程节次
 
    $post['xn']='2014-2015';//所在学年
    $post['xq']='2';//所在学期
    $post['xqj']='6';//当天星期几
    $post['dpDataGrid1:txtPageSize']=90;//每页显示条数
 
    $result = curl_request($url,$post,$cookie,0);
     
    preg_match_all('/<span[^>]+>[^>]+span>/',$result,$out);
    $tip = iconv('gb2312', 'utf-8', $out[0][3]);//获取页面前部的提示内容
    preg_match_all('/<table[\w\W]*&#63;>([\w\W]*&#63;)<\/table>/',$result,$out);
    $table = iconv('gb2312', 'utf-8', $out[0][0]); //获取查询列表
     
    $this->load->view("classroom",array('tip'=>$tip,'table'=>$table));
  }
Copy after login

  总结起来就是这些了,每个学校的教务系统都不尽相同,这时我们可以借助火狐浏览器的 firebug 抓包,看看到底提交了哪些东西。

以上所述就是本文的全部内容了,希望大家能够喜欢。
