Warning: curl_setopt() [function.curl-setopt]: CURLO...how to solve the error when using php curl function
If you run CURLOPT_FOLLOWLOCATION in PHP and then get the php prompt error message:
Warning: curl_setopt() [function.curl-setopt]: CURLOPT_FOLLOWLOCATION cannot be activated when in safe_mode or an open_basedir is set…
Error Mentioning the two key words safe_mode and open_basedir, if you are a virtual host and do not have permission to set APPCHE, you cannot solve the problem by modifying the server configuration. Generally speaking, the server configuration safe_mode is off, and then there are some security requirements for users. Restriction, by setting open_basedir to limit the PHP execution folder of the virtual host user, so when you use CURLOPT_FOLLOWLOCATION (php curl function, deep capture data), the error message mentioned in the article will appear once there is a 301 redirect, etc.
After checking the relevant information, I quickly found the solution, http://www.php.cn/php-weizijiaocheng-362563.html. These methods are all available in the official php help.
The specific method is in curl Whether to use curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true) in the statement, customize a function in the php function,
The code is as follows:
function curl_redir_exec($ch,$debug="")
{
static $curl_loops = 0;
static $curl_max_loops = 20;
if ($curl_loops++ >= $curl_max_loops)
{
$curl_loops = 0;
return FALSE;
}
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
$data = curl_exec($ch);
$debbbb = $data;
list($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)));
//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 (!$url['scheme'])
$url['scheme'] = $last_url['scheme'];
if (!$url['host'])
$url['host'] = $last_url['host'];
if (!$url['path'])
$url['path'] = $last_url['path'];*/
$new_url = $url['scheme'] . '://' . $url['host'] . $url['path'] . ($url['query']?'?'.$url['query']:'');
curl_setopt($ch, CURLOPT_URL, $new_url);
// debug('Redirecting to', $new_url);
return curl_redir_exec($ch);
} else {
$curl_loops=0;
return $debbbb;
}
}After the function is defined, replace the statement curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true) with curl_redir_exec($ch)
After this, I think your PHP file should not prompt an error. Regarding this code, you can find it in the official PHP connection.
The official code of PHP is as follows
/safe 模式不能curl的函数
function curl_redir_exec($ch)
{
static $curl_loops = 0;
static $curl_max_loops = 20;
if ($curl_loops++ >= $curl_max_loops)
{
$curl_loops = 0;
return FALSE;
}
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, 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));
if (!$url['scheme'])
$url['scheme'] = $last_url['scheme'];
if (!$url['host'])
$url['host'] = $last_url['host'];
if (!$url['path'])
$url['path'] = $last_url['path'];
$new_url = $url['scheme'] . '://' . $url['host'] . $url['path'] . ($url['query']?'?'.$url['query']:'');
curl_setopt($ch, CURLOPT_URL, $new_url);
debug('Redirecting to', $new_url);
return curl_redir_exec($ch);
} else {
$curl_loops=0;
return $data;
}
}
