PHP realizes simulated login to Founder Academic Affairs System to grab class schedule
This article mainly introduces the relevant information about PHP to simulate login to Founder Academic Affairs System to grab class schedule. Friends who need it can refer to it. Next
The two applications Course Grid and Super Course Timetable must be familiar to college students. Using your student ID and password of the educational system, you can import your own class timetable and view it on your mobile phone anytime and anywhere.
In fact, if we know a little bit about php, we can also make a web application similar to this.
1. Solve the verification code
In fact, this is a small bug of Zhengfang. When we enter the login interface, the browser will request the server, and the server will generate a verification code image. If we don't request this image, then Zhengfang's background will not generate the corresponding verification code, so we have an opportunity to take advantage of it, which will make me happy for a while ~ At this time, without filling in the verification code, Can enter very smoothly. You can disable access to the address of the verification code on your computer, and then try to see if this is true~ Of course, this only works for the positive party.
2. PHP curl simulated login
Next is the relevant code. I believe many people are like me. They only like to look at examples and turn away from long explanations... But this habit is still not good... No more nonsense!

}
curl_close($curl);
if($returnCookie){
list($header, $body) = explode("rnrn", $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. Hidden fields on the educational administration system login page
Give me a chestnut
Copy the code. The code is as follows:
These things also need to be brought when logging in. By the way, I posted the function and revealed the blogger’s school... Royal Farming University (mainly the use of regular expressions)
//Hidden fields on the login page
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 $res[0] ;
}
// Return the hidden value of the classroom query page
private function getViewJs($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] ;
}

function login($xh,$pwd){

$post['__VIEWSTATE'] = $this->getView();
$post['txtUserName'] = $xh; //Fill in the student ID
$post['TextBox2'] = $pwd; //Fill in the password
$post['txtSecretCode'] = '';
$post['lbLanguage'] = '';
$post['hidPdrs'] = '';
$post['hidsc'] = '';
$post['RadioButtonList1'] = iconv('utf-8', 'gb2312', 'Student');
$post['Button1'] = iconv('utf-8', 'gb2312', 'Login');
$result = curl_request($url,$post,'', 1);
return $result['cookie'];
}
5. Let’s try the function of checking the class schedule. The format is a bit messy. Let’s make do with it. I converted the class schedule into a two-dimensional associative array

$post['xq']='2';//semester
$post['xqj']='6';//What day of the week it is
$post['dpDataGrid1:txtPageSize']=90;//Number of items displayed per page
$result = curl_request($url,$post,$cookie,0);
preg_match_all('/] >[^>] span>/',$result,$out);
$tip = iconv('gb2312', 'utf-8', $out[0][3]);//Get the tip content at the front of the page
preg_match_all('/([wW]*?)/',$result,$out);
$table = iconv('gb2312', 'utf-8', $out[0][0]); //Get the query list
$this->load->view("classroom",array('tip'=>$tip,'table'=>$table));
}
In summary, that’s all. Each school’s educational system is different. At this time, we can use the firebug packet capture of Firefox browser to see what has been submitted.
