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("", $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
复制代码 代码如下:<input type="hidden" name="__VIEWSTATE" value="dDwyODE2NTM0OTg7Oz61eIbnKVojBioGYtg2vsy2SklwiA==">
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); $pattern = "/<input type="hidden" name="__VIEWSTATE" value="(.*?)" />/is"; preg_match_all($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); $pattern = "/<input type="hidden" name="__VIEWSTATE" value="(.*?)" />/is"; preg_match_all($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,"",$cookie); //保存的cookies preg_match_all("/<table id="Table1"[wW]*?>([wW]*?)</table>/",$result,$out); $table = $out[0][0]; //获取整个课表 preg_match_all("/<td [wW]*?>([wW]*?)</td>/",$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; } }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[^>]+>[^>]+span>/",$result,$out); $tip = iconv("gb2312", "utf-8", $out[0][3]);//获取页面前部的提示内容 preg_match_all("/<table[wW]*?>([wW]*?)</table>/",$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)); }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。
