我已将一个网站迁移到另一个网站托管。当我在localhost上测试时一切正常,但是当我在线试用时,我收到以下内容:
curl_setopt() [<a href='function.curl-setopt'>function.curl-setopt</a>]:
CURLOPT_FOLLOWLOCATION cannot be activated when safe_mode is enabled or
an open_basedir is set
当我尝试使用TCPDF生成PDF文件时(7542行生成错误)
7534 if ($imsize === FALSE) {
7535 if (function_exists('curl_init')) {
7536 // try to get remote file data using cURL
7537 $cs = curl_init(); // curl session
7538 curl_setopt($cs, CURLOPT_URL, $file);
7539 curl_setopt($cs, CURLOPT_BINARYTRANSFER, true);
7540 curl_setopt($cs, CURLOPT_FAILONERROR, true);
7541 curl_setopt($cs, CURLOPT_RETURNTRANSFER, true);
7542 curl_setopt($cs, CURLOPT_FOLLOWLOCATION, true);
我该怎么做才能避免这种情况?

如果托管公司/部门不愿意关闭safe_mode,则解决方法可能是在php.net上发现的这个有用的代码段http://php.net/manual/ro/function.curl-setopt.php#71313
function curl_redir_exec($ch)
{
static $curl_loops = 0;
static $curl_max_loops = 20;
if ($curl_loops++ >= $curl_max_loops) {
$curl_loops = 0;
return FALSE;
}
curl_setopt_array($ch, array(CURLOPT_HEADER => true, CURLOPT_RETURNTRANSFER => true));
$data = curl_exec($ch);
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)));
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));
foreach(array('scheme', 'host', 'path') as $component) {
if (!$url[$component]) {
$url[$component] = $last_url[$component];
}
}
$new_url = $url['scheme'] . '://' . $url['host'] . $url['path']
. ($url['query'] ? '?' . $url['query'] : '');
curl_setopt($ch, CURLOPT_URL, $new_url);
return curl_redir_exec($ch);
} else {
$curl_loops = 0;
return $data;
}
}

错误消息告诉您错误:
启用safe_mode或设置open_basedir时,无法激活
CURLOPT_FOLLOWLOCATION
您应该能够以这种方式获取当前配置:
var_dump(array_map('ini_get', array('safe_mode', 'open_basedir')));
要删除错误,请与您的主机托管部门联系,告诉他们您对PHP设置的技术要求。如果主机无法满足您的要求,您就为PHP脚本选择了错误的主机。
答案 2 :(得分:0)
您应该关闭主机中的safe_mode
和open_basedir
。您可以通过托管支持询问。如果它不可用,您可以将open_basedir
的值更改为(0)。
示例:
curl_setopt($rConnect, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($rConnect, CURLOPT_FOLLOWLOCATION, 1);
应该改为
curl_setopt($rConnect, CURLOPT_RETURNTRANSFER, 0);
curl_setopt($rConnect, CURLOPT_FOLLOWLOCATION, 0);
