通过对教务处登录进行抓包分析,发现登录教务处只需要两个操作

1 将username和password两个的值post到http://202.114.242.21/whkjdx/Logon.do?method=logon

2 通过1的操作以后,页面会跳转到http://202.114.242.21/whkjdx/index.jsp,接着我们post一个空表单到http://202.114.242.21/whkjdx/Logon.do?method=logonBySSO,这样才算完全登录成功,如果没有第二步,会提示权限错误

接下来给出具体的代码,有两种实现方法,一个是用curl来实现,一个是用snoopy.class.php来实现

登录过程是:

访问index.jsp(获得cookie,这是后面操作的基础)->向Logon.do?method=logon提交用户名和密码->自动跳转页面到main.jsp->由main.jsp发起Logon.do?method=logonBySSO的请求->登录过程完成->访问xszqcjglAction.do?method=queryxscj获得成绩

用curl来实现

$cookie_file = tempnam('./temp','cookie');//从首页获取session的密码

$ch = curl_init($login_url);

curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; WOW64; Trident/6.0)');

curl_setopt($ch, CURLOPT_HEADER, 1);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch, CURLOPT_MAXREDIRS, 1);

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

curl_setopt($ch, CURLOPT_AUTOREFERER, 1);

curl_setopt($ch, CURLOPT_POST, 0);curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file);curl_exec($ch);curl_close($ch);//准备提交数据登录

$send_url='http://202.114.242.21/whkjdx/Logon.do?method=logon';$post_fields='USERNAME=你的用户名&PASSWORD=你的密码&useDogCode=&useDogCode=&x=39&y=10';$ch = curl_init($send_url);

curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; WOW64; Trident/6.0)');

curl_setopt($ch, CURLOPT_HEADER, 1);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch, CURLOPT_MAXREDIRS, 1);

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

curl_setopt($ch, CURLOPT_AUTOREFERER, 1);

curl_setopt($ch, CURLOPT_POST, 1);

curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields);

curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);

curl_setopt($ch, CURLOPT_REFERER, 'http://202.114.242.21/whkjdx/');$contents = curl_exec($ch);

curl_close($ch);$send_url='http://202.114.242.21/whkjdx/framework/main.jsp';$ch = curl_init($send_url);

curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; WOW64; Trident/6.0)');

curl_setopt($ch, CURLOPT_HEADER, 1);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch, CURLOPT_MAXREDIRS, 1);

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

curl_setopt($ch, CURLOPT_AUTOREFERER, 1);

curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);

curl_setopt($ch, CURLOPT_REFERER, 'http://202.114.242.21/whkjdx/Logon.do?method=logon');curl_exec($ch);

curl_close($ch);

$send_url='http://202.114.242.21/whkjdx/Logon.do?method=logonBySSO';$post_fields='';$ch = curl_init($send_url);

curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; WOW64; Trident/6.0)');

curl_setopt($ch, CURLOPT_HEADER, 1);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch, CURLOPT_MAXREDIRS, 1);

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

curl_setopt($ch, CURLOPT_AUTOREFERER, 1);

curl_setopt($ch, CURLOPT_POST, 1);

curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields);

curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);

curl_setopt($ch, CURLOPT_REFERER, 'http://202.114.242.21/whkjdx/framework/main.jsp');curl_exec($ch);

curl_close($ch);//查询成绩

$send_url='http://202.114.242.21/whkjdx/xszqcjglAction.do?method=queryxscj';$ch = curl_init($send_url);

curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; WOW64; Trident/6.0)');

curl_setopt($ch, CURLOPT_HEADER, 1);

curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

curl_setopt($ch, CURLOPT_MAXREDIRS, 1);

curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);

curl_setopt($ch, CURLOPT_AUTOREFERER, 1);

curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);$contents = curl_exec($ch);

curl_close($ch);//输出页面的内容

print_r($contents);?>

用snoopy.class.php来实现

<?phpinclude "Snoopy.class.php";$snoopy = newSnoopy;$snoopy->expandlinks=true;$formvars["USERNAME"] = "你的用户名";$formvars["PASSWORD"] = "你的密码";$action = "http://202.114.242.21/whkjdx/Logon.do?method=logon";//表单提交地址

$snoopy->fetch("http://202.114.242.21/whkjdx/index.jsp");$snoopy->setcookies();//留下cookie,这个很重要$snoopy->submit($action,$formvars);//$formvars为提交的数组

$snoopy->fetch("http://202.114.242.21/whkjdx/framework/main.jsp");$formvars=NULL;$action="http://202.114.242.21/whkjdx/Logon.do?method=logonBySSO";$snoopy->submit($action,$formvars);$snoopy->fetch('http://202.114.242.21/whkjdx/xszqcjglAction.do?method=queryxscj');echo $snoopy->results;

?>

ps:查询成绩,只要登录成功以后,访问http://202.114.242.21/whkjdx/xszqcjglAction.do?method=queryxscj就可以了
