cURL在实时服务器上不起作用

Question

我正在尝试使用PHP和cURL在IOS发送推送通知，但是curl在我的实时服务器上不起作用，尽管在服务器上启用了curl扩展，这是我的通知文件curl代码！

<?php

error_reporting(E_ALL);
$message = "Test Notifcation";
$regId = $_REQUEST['device_id'];

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "http://examplemyserver.com/api/push.php");
curl_setopt($ch, CURLOPT_HEADER, 0);
curl_setopt($ch, CURLOPT_USERAGENT, $_SERVER["HTTP_USER_AGENT"]);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_VERBOSE, true);
$data = array(
        'deviceToken' => $regId,
        'title' => "send_notification",                 
        'message' => $message,
        'notification_id' => "test",
        'notification_title' => "test1",
        'notification_description' => "lorem",          
        'sent_date' => strtotime(date("Y-m-d H:i:s"))
);  


curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
var_dump(curl_getinfo($ch));
print_r(curl_error($ch));
$output = curl_exec($ch);       
echo 'Curl error: ' . curl_error($ch);
curl_close($ch);
print_r($output);

?> 

每当我尝试使用上面的代码运行通知文件时，它花费了超过30秒并显示以下错误：

array(26) {
  ["url"]=>
  string(50) "http://examplemyserver.com/api/push.php"
  ["content_type"]=>

  }
  ["primary_port"]=>

  ["local_ip"]=>
  string(0) ""
  ["local_port"]=>
  int(0)
}

卷曲错误：

Failed to connect to examplemyserver.com port 80: Connection refused

您能建议我什么问题，服务器配置有什么变化？

Answer 1

尝试添加此行

curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE);

之前

var_dump(curl_getinfo($ch));

如果仍然无法使用，请确保您的url正确。

Answer 2

可能是您在服务器上设置了firewall ，从而阻止了与*:80连接-与外部服务器端口80的所有连接。
