网上有大量PHP模拟登陆正方教务管理系统的方法。很多方法是行不通的，因为这些方法利用了避免调用验证码，从而使正方系统的session中不存在验证码，从而可以绕过验证码登录。不过正方在去年就修复了这个漏洞，所以，不通过验证码登录正方教务管理系统已经基本上是不可能的了。
下面这个程序是通过先请求验证码，获得header中set-cookie头的session对应的cookie值，再将cookie与验证码同时传入登录接口，进行登陆。动手能力强的人现在可以试着做一做了，基础不好或者懒得写的可以继续往下看。
获取验证码的php程序源码：
<?php
error_reporting(0); //先把错误屏蔽了，不然图片无法显示出来
session_start(); //开启session，之后用来存入获取到的cookies
$url="http://210.31.122.189/CheckCode.aspx"; //这个换成教务系统的地址
function curl_request($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($curl, CURLOPT_REFERER, "http://210.31.122.189/CheckCode.aspx"); //填写教务系统url
if($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;
}
}
$arr=curl_request($url,'','', 1);
$_SESSION["ck"]=$arr["cookie"]; //存入cookies
echo $arr["content"]; //输出图片[/hide]
模拟登陆并抓取课程表转化为json信息的php源码：

$ck=$_SESSION['ck'];
