file_get_contents does not work on port 8282

问题

I got the following basic script who make a basic POST request (I just want to make it work, after I'll add more stuff) :

#   Variables
$URL = 'http://******:8282/api/incoming_shipment/';

$postdata = http_build_query(
    array(
        'contract_id'       => 'Showcare-R124276',
        'shipment_from'     => 'Montréal',
        'shipment_to'       => 'Chicago',
        'shipping_time'     => '2012-08-16 14:51:01',
        'tracking_cie'      => 'Poste Canada',
        'tracking_type'     => 'Standard',
        'tracking_number'   => 'EP645 9834 123 9773'
    )
);

$opts = array('http' =>
    array(
        'method'  => 'POST',
        'header'  => 'Content-type: application/x-www-form-urlencoded',
        'content' => $postdata
    )
);

$context = stream_context_create($opts);

$result = file_get_contents($URL, FALSE, $context);

print_r($result);

The result give me :

Warning: file_get_contents(http://******:8282/api/incoming_shipment/) [function.file-get-contents]: failed to open stream: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond. in D:\Inetpub\hightechhandling\api\api_push_contract.php on line 31

Fatal error: Maximum execution time of 30 seconds exceeded in D:\Inetpub\hightechhandling\api\api_push_contract.php on line 31

But When I go to the webpage with my browser, it work perfectly. I have tryed cURL and fsocketopen but that didn't work too. Any help please ? Thanks..

EDIT I added set_time_limit (500); and now the second error has disapear of course... but the first still remain.

回答1:

Ok, found the problem. Was sooo stupid. The problem is because the server that make the request (where the PHP file is), has a firewall enabled and the firewall allow only port 21, 22, 80, 3306 and 1433 for external request.

回答2:

For CentOS, using file_get_contents() to access URL on port other than 80 doesn't works with permission denied. It works only when selinux is set to "disabled" or "permissive".

回答3:

From PHP Manual

void set_time_limit ( int $seconds )

Set the number of seconds a script is allowed to run. If this is reached, the script returns a fatal error. The default limit is 30 seconds or, if it exists, the max_execution_time value defined in the php.ini.

When called, set_time_limit() restarts the timeout counter from zero. In other words, if the timeout is the default 30 seconds, and 25 seconds into script execution a call such as set_time_limit(20) is made, the script will run for a total of 45 seconds before timing out. If set to zero, no time limit is imposed.

回答4:

Try this:

'header' => implode("\r\n", array("Connection: close", "Content-type: application/x-www-form-urlencoded")),

(especially the connection: close bit)

Also: Can you duplicate the problem on the commanline with curl?

回答5:

If you don't want to disable selinux for security consideration, you can modify selinux policy for allow httpd to listen 8282

To list which ports allowed for httpd: semanage port -l | grep -w http_port_t

To add port 8282: semanage port -a -t http_port_t -p tcp 8282
