这是来自你的工作场所还是什么?许多公司在共享 PHP 安装时禁用 file_get_contents(),因为它非常危险。
该网站可能有用户代理检测。你可以在你的 curl 调用中伪造它,但我不相信 file_get_contents() 可以做到这一点。网站使用的另一种方法是仅在设置 cookie 后才显示内容,这样网站抓取工具就永远不会看到数据。
试试这个:
function curl_scrape($url,$data,$proxy,$proxystatus)
{
$fp = fopen("cookie.txt", "w");
fclose($fp);
$ch = curl_init();
curl_setopt($ch, CURLOPT_COOKIEJAR, "cookie.txt");
curl_setopt($ch, CURLOPT_COOKIEFILE, "cookie.txt");
curl_setopt($ch, CURLOPT_USERAGENT, "Mozilla/4.0 (compatible; MSIE 5.01; Windows NT 5.0)");
curl_setopt($ch, CURLOPT_TIMEOUT, 40);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
if ($proxystatus == 'on')
{
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, FALSE);
curl_setopt($ch, CURLOPT_HTTPPROXYTUNNEL, TRUE);
curl_setopt($ch, CURLOPT_PROXY, $proxy);
}
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, TRUE);
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER['HTTP_USER_AGENT']);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, TRUE);
curl_setopt($ch, CURLOPT_POST, TRUE);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
ob_start(); // prevent any output
return curl_exec ($ch); // execute the curl command
ob_end_clean(); // stop preventing output
curl_close ($ch);
unset($ch);
}
