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!

//Simulated login 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($curl, CURLOPT_REFERER, "This must be replaced with the url for login to the educational administration system"); //Fill in the educational administration system url if($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("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 $res[0] ; } |
1 2 3 4 5 6 7 8 9 10 11 12 13 14 | function login($xh,$pwd){ $url = 'http://jw.hzau.edu.cn/default2.aspx'; $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
?

//Return class schedule string private function classresult($xh,$pwd){ date_default_timezone_set("PRC"); //Time zone setting $classList = "";//Declare class schedule variables
$cookie = $this->login($xh,$pwd); $view = $this->getViewJs($cookie,$xh);//Verify whether the password is correct
//If the password is correct if (!empty($view)) { $url = "http://jw.hzau.edu.cn/xskbcx.aspx?xh={$xh}"; $result = curl_request($url,'',$cookie); //Saved cookies preg_match_all('/ $table = $out[0][0]; //Get the entire class schedule
preg_match_all('/ | ([wW]*?) | /',$table,$out);
6. Try the function of querying empty classrooms again
