【问题描述】：

我是一名 php 开发人员。我正在为 iPhone 实现一个推送通知模块。为此，我使用 php 进行服务器端实现。虽然我收到“已连接到 APNS "aps":"alert":"HI Push","badge":1,"sound":"default"消息已成功传递”消息，但 iPhone 没有收到任何通知.我的php代码是这样的：

<? php
  include('include/connect.php');
  $device = mysql_query("SELECT device_token,badge,alert,sound FROM push_notification WHERE device_status='1' ");
  while($res = mysql_fetch_array($device))
     // Put your device token here (without spaces):
     $deviceToken = $res['device_token'];
     // Put your private key's passphrase here:
     $passphrase = "pushchat";
     // Put your alert message here:
     //$message = trim($_REQUEST['alert']);
     $message = "HI Push" ;
////////////////////////////////////////////////////////////////////////////////
     $ctx = stream_context_create();
     stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem');
     stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);
     // Open a connection to the APNS server
     $fp = stream_socket_client(
       'ssl://gateway.sandbox.push.apple.com:2195', $err,$errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);            
    if (!$fp)
      exit("Failed to connect: $err $errstr" . PHP_EOL);            echo 'Connected to APNS' . PHP_EOL;         
         $body['aps'] = array('alert' => $message,'badge' => 1,'sound' => 'default');       // Encode the payload as JSON
    $payload = json_encode($body);
    echo $payload;
    // Build the binary notification
    $msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;

    // Send it to the server
    $result = fwrite($fp, $msg, strlen($msg));

    if (!$result)
       echo 'Message not delivered' . PHP_EOL;
    else
       echo 'Message successfully delivered' . PHP_EOL;

    // Close the connection to the server
       fclose($fp); 

?>

目标c代码如下：

 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

    self.window = [[[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]] autorelease];
    // Override point for customization after application launch.

    // Register for Push Notification Type    

    deviceTokenString=[[NSString alloc]init];


    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound) ];

    /*---------------Increasing Badge No-----------*/

    application.applicationIconBadgeNumber=0;




#pragma mark-
#pragma mark PushNotification Delegate methods
/*------ Provide a user explanation for a place to get Device Token-------*/
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken

    /*---------Get The Device Token here--------------*/




    deviceTokenString = [deviceToken description];
    deviceTokenString = [deviceTokenString stringByTrimmingCharactersInSet:[NSCharacterSet characterSetWithCharactersInString:@"<>"]];
    deviceTokenString = [deviceTokenString stringByReplacingOccurrencesOfString:@" " withString:@""];










    /*------ Provide a user explanation for when the registration fails-------*/
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error 


    NSLog(@"Error in registration. Error: %@", error); 



- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo


    NSLog(@"Received Notification");

    NSLog(@"remote notification: %@",[userInfo description]);
    NSDictionary *apsInfo = [userInfo objectForKey:@"aps"];

    NSString *alert = [apsInfo objectForKey:@"alert"];
    NSLog(@"Received Push Alert: %@", alert);

    NSString *sound = [apsInfo objectForKey:@"sound"];
    NSLog(@"Received Push Sound: %@", sound);

    NSString *badge = [apsInfo objectForKey:@"badge"];
    NSLog(@"Received Push Badge: %@", badge);

    application.applicationIconBadgeNumber = [[apsInfo objectForKey:@"badge"] integerValue];

【问题讨论】：

您是否拥有正确的证书组合——沙盒服务器使用测试证书和开发者证书来构建应用程序？

【参考方案1】：

请检查证书是否匹配。例如。如果 iphone 处于调试模式，服务器也使用开发者证书来推送通知，如果 iPhone 是在发行版中构建的，那么服务器使用生产证书来发送推送通知。请验证您的证书是否匹配。还要检查 iPhone 设置是否为您的应用启用了通知。

【讨论】：

非常感谢，开发者证书可以正常使用。

但在生产证书中，我无法获取设备令牌。我们的服务器有什么需要改变的吗？请帮帮我。

在使用生产证书时，您不能使用沙箱发送推送通知。必须使用直接 apns 服务器 url 发送推送通知。

点赞$fp = stream_socket_client('ssl://gateway.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT, $ctx);

很抱歉，我没有注意到您无法获取设备令牌。为此，请尝试从您的系统中删除现有的分发证书。从您的 Apple 开发者帐户中重新下载它，然后尝试使用该证书进行构建。
