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; } }
3,教务系统登陆页面的隐藏字段
举个栗子
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); $pattern = '//is'; preg_match_all($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){ $url = "http://jw.hzau.edu.cn/xxjsjy.aspx?xh={$xh}"; $result = curl_request($url,'',$cookie); $pattern = '//is'; preg_match_all($pattern, $result, $matches); $res[0] = $matches[1][0]; return $res[0] ; }
4,cookie 的获取
function login($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 $result['cookie']; }
5,让我们来试试查课表的功能,格式有点乱额,大家凑合着看,我把课表转成了一个二维关联数组
//返回课表字符串 private function classresult($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)) { $url = "http://jw.hzau.edu.cn/xskbcx.aspx?xh={$xh}"; $result = curl_request($url,'',$cookie); //保存的cookies preg_match_all('/
([\w\W]*?)<\/td>/',$table,$out);
$td = $out[1];
$length = count($td);
//获得课程列表
for ($i=0; $i < $length; $i++) {
$td[$i] = str_replace(" ", "", $td[$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; } } 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);
$url = "http://jw.hzau.edu.cn/xs_main.aspx?xh={$xh}";
$result = curl_request($url,'',$cookie); //保存的cookies
$url="http://jw.hzau.edu.cn/xxjsjy.aspx?xh={$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>/',$result,$out);
$tip = iconv('gb2312', 'utf-8', $out[0][3]);//获取页面前部的提示内容
preg_match_all('/ |
