CURLOPT_FOLLOWLOCATION无法激活

Question

我有卷发的问题,我不知道如何解决它们.

想法是获取用户的用户名和密码,并将其发布到外部网页.

这是代码:

$ch = curl_init(); 
  curl_setopt( $ch, CURLOPT_URL, "https://sso.uc.cl/cas/login?service=https://portaluc.puc.cl/uPortal/Login"); // URL to post 
  curl_setopt ($ch, CURLOPT_POST, 1);
  curl_setopt ($ch, CURLOPT_POSTFIELDS,         "username=$usuario&password=$pw");
  curl_setopt ($ch, CURLOPT_FOLLOWLOCATION, 1);
  $result = curl_exec( $ch ); // runs the post 
  curl_close($ch);
  echo "Reply Response: " . $result; // echo reply response 

这是错误:

Warning: curl_setopt() [function.curl-setopt]: CURLOPT_FOLLOWLOCATION cannot be activated when safe_mode is enabled or an open_basedir is set in /home/th000862/public_html/encuesta/login2.php on line 10

在该错误之后,用户未登录到外部网页.

该错误意味着您的PHP配置禁止您访问该位置.有几种方法可以解决问题而无需安装@mario建议的其他库.

• 如果您拥有服务器或具有root访问权限,则可以更改php.ini文件以禁用"safe_mode".
• 您还可以在文档根目录中创建.htaccess文件php_value safe_mode off.
• 您可以添加ini_set('safe_mode', false);PHP文件.

如果以上都不起作用,您也可以沿着这些方向做一些事情:

$ch = curl_init('https://sso.uc.cl/cas/login?service=https://portaluc.puc.cl/uPortal/Login');

curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, 'username=' . urlencode($usuario) . '&password=' . urlencode($pw));
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, FALSE);
curl_setopt($ch, CURLOPT_NOBODY, TRUE);
curl_setopt($ch, CURLOPT_HEADER, TRUE);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookie.txt');
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookie.txt');

$result = curl_exec($ch);

curl_close($ch);

// Look to see if there's a location header.
if ( ! empty($result) )
  if ( preg_match('/Location: (.+)/i', $result, $matches) )
  {
    // $matches[1] will contain the URL.
    // Perform another cURL request here to retrieve the content.
  }
