PHP Curl Live服務器不起作用

Question

我在本地主機上測試了腳本，並且腳本運行良好。 我在實時服務器上嘗試過，但無法正常工作。

<?php
   $uploadfile=dirname(__FILE__)."/xml_request/cat.xml"; 
   $ch = curl_init("http://remote.xxxxxxxxxx.com.au:8090/Options.API");   
   curl_setopt($ch, CURLOPT_POSTFIELDS,
               array('Request'=>"@$uploadfile",
                     'clientKey'=>'xxxxxxxxxxxxxxxxxxx'));
   curl_setopt($ch, CURLOPT_PORT, '8090');
   curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
   $postResult = curl_exec($ch);

   $response = curl_getinfo($ch);
   echo "<pre>";
   print_r($response);
   echo "</pre>";

   curl_close($ch);
   echo "<pre>";
   print_r($postResult);
   //file_put_contents(dirname(__FILE__).'/xml_record/live.xml', $postResult);

?>

本地主機我print_r curl_getinfo（$ ch）。

Array
(
    [url] => http://remote.xxxxxxxx.com.au:8090/Options.API
    [content_type] => text/html; charset=utf-8
    [http_code] => 200
    [header_size] => 246
    [request_size] => 215
    [filetime] => -1
    [ssl_verify_result] => 0
    [redirect_count] => 0
    [total_time] => 2.278
    [namelookup_time] => 0
    [connect_time] => 0.344
    [pretransfer_time] => 0.344
    [download_content_length] => 9376
    [upload_content_length] => 759
    [starttransfer_time] => 0.734
    [redirect_time] => 0
    [certinfo] => Array
        (
        )

    [redirect_url] => 
)

實時測試我print_r curl_getinfo（$ ch）。

 Array
    (
        [url] => http://remote.xxxxxxxxxxx.com.au:8090/Options.API
        [content_type] => 
        [http_code] => 0
        [header_size] => 0
        [request_size] => 0
        [filetime] => -1
        [ssl_verify_result] => 0
        [redirect_count] => 0
        [total_time] => 0.012024
        [namelookup_time] => 0.011809
        [connect_time] => 0
        [pretransfer_time] => 0
        [download_content_length] => -1
        [upload_content_length] => -1
        [starttransfer_time] => 0
        [redirect_time] => 0
    )

不確定網址的端口是否有問題。 我試圖尋找解決問題的方法，但是沒有運氣。

來自評論：

您的網絡主機可能會阻止端口8090上的出站流量。許多網絡主機會阻止不常見的端口，以提高安全性。 解決此問題的唯一方法是聯系您的虛擬主機，並要求他們解除阻止該端口的權限，以便您可以連接它。
