我正在为 android 开发推送通知服务,并为此遵循了一些教程。我试图在 localhost 中实现该技术并成功了。但是,当我尝试使用远程服务器时,它给了我错误“Curl 失败:无法连接到:权限被拒绝”。我不知道它有什么问题。我尝试寻找解决方案,但没有一个有效。这是我做的步骤。
我为云消息传递创建了一个名为 GCM 的数据库 在 publish_content.php 页面中添加了以下代码行
$username = "given";
$password = "given";
$hostname = "localhost";
//connection to the database
$dbhandle = mysql_connect($hostname, $username, $password)
or die("Unable to connect to MySQL");
// echo "Connected to MySQL<br>";
//select a database to work with
$selected = mysql_select_db("gcm",$dbhandle)
or die("Could not select examples");
//execute the SQL query and return records
$result = mysql_query("SELECT gcm_regid FROM gcm_users");
$regIds = array();
include_once 'GCM.php';
//fetch tha data from the database
while ($row = mysql_fetch_array($result)) {
array_push($regIds, $row['gcm_regid']);
}
foreach($regIds as $item) {
$gcm = new GCM();
$registatoin_ids = array($item);
$message = array("price" => $message1);
$result = $gcm->send_notification($registatoin_ids, $message);
}
//close the connection
mysql_close($dbhandle);
GCM.php
<?php
class GCM {
//put your code here
// constructor
function __construct() {
}
/**
* Sending Push Notification
*/
public function send_notification($registatoin_ids, $message) {
// include config
include_once './config.php';
// Set POST variables
$url = 'https://android.googleapis.com/gcm/send';
$fields = array(
'registration_ids' => $registatoin_ids,
'data' => $message,
);
$headers = array(
'Authorization: key=' . GOOGLE_API_KEY,
'Content-Type: application/json'
);
// Open connection
$ch = curl_init();
// Set the url, number of POST vars, POST data
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_POST, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// Disabling SSL Certificate support temporarly
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($fields));
// Execute post
$result = curl_exec($ch);
if ($result === FALSE) {
die('Curl failed: ' . curl_error($ch));
}
// Close connection
curl_close($ch);
echo $result;
}
}
?>
它连接到mysql,然后显示该错误。请帮助我。
