使用 curl 和 file_get_contents POST 数据：连接被拒绝

Question

im trying post data use curl & file_get_contents to 'url1' but get some error Connection Refused, but when post data to 'url2' its normal.

Curl :

$post = ['data1'=>'A','data2'=>'B'];
$ch = curl_init('url1');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);
$response = curl_exec($ch);
curl_close($ch);
var_dump($response);

curl: (7) Failed to connect to url1 port 82: Connection refused

file_get_contents:

$data = array('data1'=>'A','data2'=>'B');
$options = array(
                'http' => array(
                    'header'  => "Content-type: application/x-www-form-urlencoded\r\n",
                    'method'  => 'POST',
                    'content' => http_build_query($data),
                    ),
            );
$context  = stream_context_create($options);
$result = file_get_contents('url1', false, $context);
var_dump($result);

Warning: file_get_contents(url1): failed to open stream: Connection refused

did i make mistake with this code ?

This question seems to relate to target server or firewall configuration. You can check the target firewall settings or use all headers required at destination server. First try to use and add a proper value for origin header.

If the problem is not the firewall, you can take a look at https://www.w3.org/wiki/CORS .
