課程格子和超級課表這兩個應用,想必大學生都很熟悉,使用自己的學號和教務系統的密碼,就可以將自己的課表導入,隨時隨地都可以在手機上查看。
其實稍微了解一點php的話,我們也可以做一個類似這樣的web 應用。
1,解決掉驗證碼
其實這是正方的一個小bug,當我們進入登陸介面時,瀏覽器會去請求伺服器,伺服器會產生一個驗證碼圖片。如果我們不去請求這個圖片,那麼正方後台也不會產生對應的 驗證碼,於是這樣我們就有了可乘之機,讓我高興會兒~這時,我們在不填寫驗證碼的情況下,可以很流暢的進入。大家可以在自己的電腦上禁止存取驗證碼的位址,然後試試這 是不是真的~當然,這只對正方有效。
2,php 的curl 模擬登陸
這裡直接貼一個腳本之家對curl 的講解吧 http://www.jb51.net/article/51299.htm解『跟我一樣,只喜歡看例子,對於長篇大論的講解,轉頭就走……不過這個習慣還是不好……廢話不多說!
//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("\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; } }
3,教務系統登陸頁的隱藏字段
舉個栗子
<input type="hidden" name="__VIEWSTATE" value="dDwyODE2NTM0OTg7Oz61eIbnKVojBioGYtg2vsy2SklwiA==">
暴帶的東西也是耵耵漏登陸的東西也是需要函數的東西。 …皇家種地大學(主要是正規表示式的運用)

private function getViewJs($cookie,$xh){
