curl學習 - 用cURL登陸 並下載個人空間頁面

仿慕課網上的教程，但是沒有成功

$data = 'username=用戶名&password=密碼';
$curlobj = curl_init();
curl_setopt($curlobj,CURLOPT_URL,'http://www.***.cn/index.php/Home/Public/dologin');  //設置訪問的url地址
curl_setopt($curlobj,CURLOPT_RETURNTRANSFER,true);  //執行之後不直接打印出來

//cookie相關設置，這部分設置需要在所有回話開始之前設置
date_default_timezone_set('PRC');   //使用cookie時，必須先
curl_setopt($curlobj,CURLOPT_COOKIESESSION,TRUE);
curl_setopt($curlobj,CURLOPT_COOKIEFILE,"cookiefile");
curl_setopt($curlobj,CURLOPT_COOKIEJAR,"cookiefile");
curl_setopt($curlobj,CURLOPT_COOKIE,session_name() . '=' . session_id());
curl_setopt($curlobj,CURLOPT_HEADER,0);
curl_setopt($curlobj,CURLOPT_FOLLOWLOCATION,1);  //讓cURL支持頁面跳轉

curl_setopt($curlobj,CURLOPT_POST,1);
curl_setopt($curlobj,CURLOPT_POSTFIELDS,$data);
curl_setopt($curlobj,CURLOPT_HTTPHEADER,array("application/x-www-form-urlencoded;charset=utf-8","Content-length: ".strlen($data))); 
curl_exec($curlobj);  

curl_setopt($curlobj,CURLOPT_URL,"http://www.***.cn/index.php/Member/Posts/business");
curl_setopt($curlobj,CURLOPT_POST,0);
curl_setopt($curlobj,CURLOPT_HTTPHEADER,array("Content-type:text/xml"));
$output = curl_exec($curlobj);
curl_close($curlobj);
echo $output;

下面這一段成功登陸

$cookie_file    =    tempnam('./temp','cookie');
$login_url        =    'http://www.***.cn/index.php/Home/Public/dologin';
$post_fields    =    'username=用戶名&password=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, $cookie_file);
curl_setopt($ch,CURLOPT_FOLLOWLOCATION,1);  //讓cURL支持頁面跳轉
curl_exec($ch);
curl_close($ch);


$url='http://www.***.cn/index.php/Member/Posts/business';
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file);
$contents = curl_exec($ch);
echo $contents;
curl_close($ch);
