APNS 服务推送通知

1. 将app注册notification里面, 并从APNS上获取测试机的deviceToken.    

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {        
    [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)];  
        // other codes here.    
    return YES;
}
 
- (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
    NSLog(@"deviceToken: %@", deviceToken);
}
 
- (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error {
    NSLog(@"Error in registration. Error: %@", error);
}
 
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
{
    
    NSLog(@" 收到推送消息 ： %@",[[userInfo objectForKey:@"aps"] objectForKey:@"alert"]);
    if ([[userInfo objectForKey:@"aps"] objectForKey:@"alert"]!=NULL) {
        UIAlertView* alert = [[UIAlertView alloc] initWithTitle:@"推送通知"
                                                        message:[[userInfo objectForKey:@"aps"] objectForKey:@"alert"]
                                                       delegate:self
                                              cancelButtonTitle:@" 关闭"
                                              otherButtonTitles:@" 更新状态",nil];
        [alert show];
        [alert release];
    }
}

启动程序，将app注册到通知项后，在console里面找到打印的deviceToken：

1. deviceToken: <6974ac11 870e09fa 00e2238e 8cfafc7d 2052e342 182f5b57 fabca445 42b72e1b>

2. 生成app在服务端需要的许可证
1）进入Provisioning Portal, 下载Certificates在development下的证书。 
2） 找到需要测试的app id,然后enable它在development下的Apple Push Notification service: Development Push SSL Certificate。需要输入1）中的签名证书才可以生成一个aps_developer_identity.cer.
3) 双击aps_developer_identity.cer，会打开系统的key chain. 在My certificates下找到Apple Development Push Services。需要为certificate和它之下的private key各自export出一个.p12文件。(会出现设置密码过程)
4）需要将上面的2个.p12文件转成.pem格式：

1. openssl pkcs12 -clcerts -nokeys -out cert.pem -in cert.p12

1. openssl pkcs12 -nocerts -out key.pem -in key.p12

5）如果需要对 key不进行加密：
  

1. openssl rsa -in key.pem -out key.unencrypted.pem

6）然后就可以 合并两个.pem文件, 这个ck.pem就是服务端需要的证书了。
  

1. cat cert.pem key.unencrypted.pem > ck.pem

3. 服务端push通知到ANPS. 在cocoachina找到了两种方法:
  1）php驱动。需要将ck.pem和php脚本放到server 上。全部的php代码是：
    

1. $deviceToken = '6974ac11 870e09fa 00e2238e 8cfafc7d 2052e342 182f5b57 fabca445 42b72e1b';
   $pass = '123456';   // Passphrase for the private key (ck.pem file)
    
   // Get the parameters from http get or from command line
   $message = $_GET['message'] or $message = $argv[1] or $message = 'A test message from worldcup';
   $badge = (int)$_GET['badge'] or $badge = (int)$argv[2];
   $sound = $_GET['sound'] or $sound = $argv[3];
    
   // Construct the notification payload
   $body = array();
   $body['aps'] = array('alert' => $message);
   if ($badge)
     $body['aps']['badge'] = $badge;
   if ($sound)
     $body['aps']['sound'] = $sound;
    
   /* End of Configurable Items */
   $ctx = stream_context_create();
   stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem');  
   // assume the private key passphase was removed.
   stream_context_set_option($ctx, 'ssl', 'passphrase', $pass);
    
   // connect to apns
   $fp = stream_socket_client('ssl://gateway.sandbox.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT, $ctx);
   if (!$fp) {
       print "Failed to connect $err $errstr
   ";
       return;
   }
   else {
      print "Connection OK
   
   ";
   }
    
   // send message
   $payload = json_encode($body);
   $msg = chr(0) . pack("n",32) . pack('H*', str_replace(' ', '', $deviceToken)) . pack("n",strlen($payload)) . $payload;
   print "Sending message :" . $payload . "
   ";  
   fwrite($fp, $msg);
   fclose($fp);
   ?>

请 求一次 http://127.0.0.1/apns/apns.php?message=A%20test%20message%20from%20localhost&badge=2&sound=received5.caf就 会向APNS进行一次推送。我的请求结果如下：

1. Connection OK
2. Sending message :{"aps":{"alert":"A test message from localhost","badge":2,"sound":"received5.caf"}}

  2）pushMeBaby 驱动。将aps_developer_identity.cer导入到project里面，改名为apns.cer。
