類比登入 - php CURL類比登陸正方教務系統

代碼如下

$cookie_file    =    tempnam('./temp','cookie');$login_url        =    'http://211.64.47.129/default_ysdx.aspx';$post_fields    =    '__VIEWSTATE=dDw1MjQ2ODMxNzY7Oz7xlHJHd0KfeVRA2p7BXNto118wbQ==&TextBox1=學號&TextBox2=密碼';$ch = curl_init($login_url);curl_setopt($ch, CURLOPT_HEADER, 0);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);curl_setopt($ch, CURLOPT_POST, 1);curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields);curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file);curl_exec($ch);curl_close($ch);$url='http://211.64.47.129/xs_main.aspx?xh=學號';$ch = curl_init($url);curl_setopt($ch, CURLOPT_HEADER, 0);curl_setopt($ch, CURLOPT_RETURNTRANSFER, 0);curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);$contents = curl_exec($ch);preg_match("/
 (.*)<\/li>/",$contents,$arr);echo $arr[1];curl_close($ch);

但是最後卻回到了登入的介面，小白求大神解答

根據樓主的要求, 配合我自己寫的 HttpClient 的類, 編寫的代碼如下, 但因為沒有測試帳號, 所以測試時使用的帳號和密碼為 test, 返回的結果是登陸失敗, 樓主只需要修改代碼裡的帳號和密碼, 應該就可以了.
HTTP 請求過程中的 Cookie 由 HttpClient/CURL 自動處理.

樓主發的代碼應該是沒問題的, 感覺應該是沒有提交 RadioButtonList1 和 Button1 這兩個資料.
還有那個__VIEWSTATE 雖然看起來是固定的, 但為了保險期間, 還是應該從頁面中擷取到之後, 再提交登陸.

附代碼:
