如上代码并不完美,我们应该把cookie存到缓存中,不应该持久化,并且这样的持久化只能是单用户访问才行。
所以,其实我们只要设置
CURLOPT_COOKIESESSION
如下即可
= $curl_max_loops) { $curl_loops = 0; return FALSE; } curl_setopt($ch, CURLOPT_HEADER, true); // 开启header才能够抓取到重定向到的新URL curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); $data = curl_exec($ch); // 分割返回的内容 $h_len = curl_getinfo($ch, CURLINFO_HEADER_SIZE); $header = substr($data,0,$h_len); $data = substr($data,$h_len - 1); $http_code = curl_getinfo($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 (!isset($url['scheme'])) $url['scheme'] = $last_url['scheme']; if (!isset($url['host'])) $url['host'] = $last_url['host']; if (!isset($url['path'])) $url['path'] = $last_url['path']; $new_url = $url['scheme'] . '://' . $url['host'] . $url['path'] . (isset($url['query'])?'?'.$url['query']:''); curl_setopt($ch, CURLOPT_URL, $new_url); return curl_redir_exec($ch); } else { $curl_loops=0; return $data; } } ?>
