php CURLOPT错误Warning: curl_setopt() [function.curl-setopt]:...
如果当你在php中运行 CURLOPT_FOLLOWLOCATION 然后得到php提示错误信息为:
Warning: curl_setopt() [function.curl-setopt]: CURLOPT_FOLLOWLOCATION cannot be activated when in safe_mode or an open_basedir is set…
错误中提到两个关键safe_mode和 open_basedir,如果你是虚拟主机的没有设置APPCHE的权限是不能通过修改服务器配置来解决问题的,一般来说,服务器配置safe_mode都为off,然后为了一些安全对用户有一些限制,通过设置open_basedir来限制虚拟主机用户的PHP执行文件夹,因此当你使用CURLOPT_FOLLOWLOCATION (php curl函数,深层抓取数据)的时候,一旦有301转向等就会出现文中提到的错误信息.
在查了相关资料后,很快找到了解决办法,http://www.php.net/manual/en/function.curl-setopt.php,这些方法都在php官方帮助里有.
具体做法是在curl语句用不使用curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true),在php函数中自定义一个函数,代码如下:
= $curl_max_loops) { $curl_loops = 0; return FALSE; } curl_setopt($ch, CURLOPT_HEADER, true); curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $data = curl_exec($ch); $debbbb = $data; list($header, $data) = explode("\n\n", $data, 2); $http_code = curl_getinfo($ch, CURLINFO_HTTP_CODE); if ($http_code == 301 || $http_code == 302) { $matches = array(); preg_match('/Location:(.*?)\n/', $header, $matches); $url = @parse_url(trim(array_pop($matches))); //print_r($url); if (!$url) { //couldn't process the url to redirect to $curl_loops = 0; return $data; } $last_url = parse_url(curl_getinfo($ch, CURLINFO_EFFECTIVE_URL)); /* if (!$url['scheme']) $url['scheme'] = $last_url['scheme']; if (!$url['host']) $url['host'] = $last_url['host']; if (!$url['path']) $url['path'] = $last_url['path'];*/ $new_url = $url['scheme'] . '://' . $url['host'] . $url['path'] . ($url['query'] ? '?' . $url['query'] : ''); curl_setopt($ch, CURLOPT_URL, $new_url); // debug('Redirecting to', $new_url); return curl_redir_exec($ch); } else { $curl_loops = 0; return $debbbb; } }
函数定义好后, curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true) 这条语句替换为curl_redir_exec($ch) . 这样以后, 我想你的PHP文件应该不会提示错误了, 关于这段代码, 在提供PHP官方连接用可以找到 .
