CURLOPT_FOLLOWLOCATION无法激活

Question

所以我一直在多个服务器上得到这个恼人的错误(它是一个警告,所以我忽略它,但我需要这个功能)

警告:curl_setopt()[function.curl-setopt]:启用safe_mode或在第56行的/home/xxx/public_html/xxx.php中设置open_basedir时,无法激活CURLOPT_FOLLOWLOCATION

我将如何通过SSH解决此问题？

Answer 1

safe_mode = Off在php.ini文件中设置(通常在服务器上的/ etc /中).如果已经关闭了,那么请查看open_basedirphp.ini文件中的内容,并相应地进行更改.

基本上,以下位置选项已被禁用作为安全措施,但PHP的内置安全功能通常比安全更烦人.实际上,safe_mode 在PHP 5.3中已弃用.

Answer 2

试试这个,如果需要重定向并且启用了safemode,它将遵循基于标题的链接(如果你抓取图像虽然这不会起作用,因为它会将标题添加到返回中),这是针对您的特定问题的解决方法,当客户安装了我的一个脚本时,我遇到了同样的问题,所以不得不提出这个问题.它还会将错误记录到:curl.error.log..有用的呃
