我正在使用的代码使我无法使用CURL拍摄图片。
public function getRemoteFile($url, $dest, $authmode = null, $cookies = null)
{
$context = $this->createContext($url);
$ch=$context['curlhandle'];
$dl_opts = $context['opts']['dl'];
$outname = $dest;
if ($cookies)
{
if (substr($url, 0, 4) == "http")
{
$dl_opts[CURLOPT_COOKIE] = $cookies;
}
}
$fp = fopen($outname, "w");
if ($fp == false)
{
$this->destroyContext($context);
throw new Exception("Cannot write file:$outname");
}
$dl_opts[CURLOPT_FILE] = $fp;
$this->setURLOptions($url, $dl_opts);
$this->setAuthOptions($context,$dl_opts);
// Download the file , force expect to nothing to avoid buffer save problem
curl_setopt_array($ch, $dl_opts);
$inf = curl_getinfo($ch);
if (!curl_exec($ch))
{
if (curl_error($ch) != "")
{
$err = "Cannot fetch $url :" . curl_error($ch);
}
else
{
$err = "CURL Error downloading $url";
}
$this->destroyContext($context);
fclose($fp);
unlink($dest);
throw new Exception($err);
}
else
{
$proto=$context['scheme'];
if($proto=='http' || $proto=='https')
{
$httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
$ok = ($httpCode < 400);
if(!$ok)
{
fclose($fp);
@unlink($outname);
throw new Exception('Cannot fetch URL :'.$url);
}
}
}
fclose($fp);
$this->destroyContext($context);
return true;
}
我得到以下输出:
警告:curl_setopt_array():启用safe_mode或在第290行的/usr/home/shop.domain.com/web/productimport/inc/remotefilegetter.php中设置了open_basedir时,无法激活CURLOPT_FOLLOWLOCATION。
我还尝试查看 $ dl_opts 会发生什么,因为在我打电话时错误开始出现:
curl_setopt_array($ch, $dl_opts);
所以在 $ dl_opts 里面,我得到了:
Array ( [80] => 1 [42] => 0 [44] => 0 [52] => 1 [10023] => Array ( [0] => Expect: ) [19913] => [19914] => 1 [10001] => Resource id #261 [10002] => http://domain/picture/static/l0033.jpg )

答案 0 :(得分:0)
显然,使用CURLOPT_FOLLOWLOCATION允许301和302重定向将跟随重定向到file:// URL。 (找到对PHP源代码的提交:https://github.com/php/php-src/commit/fba290c061027c24e4c8effdba37addd3430c3d4)
如果允许重定向到file:// URL,则控制最初请求的URL的任何人都可以使您的PHP脚本从服务器的本地磁盘中获取文件。然后,可以使用从用户获取URL并显示内容的Web服务,从PHP可以访问的服务器磁盘中读取任何文件。
