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.    

1 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { 2 [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeBadge | UIRemoteNotificationTypeSound)]; 3 // other codes here. 4 return YES; 5 } 6 7 - (void)application:(UIApplication *)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken { 8 NSLog(@"deviceToken: %@", deviceToken); 9 } 10 11 - (void)application:(UIApplication *)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)error { 12 NSLog(@"Error in registration. Error: %@", error); 13 } 14 15 - (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo 16 { 17 18 NSLog(@" 收到推送消息 ： %@",[[userInfo objectForKey:@"aps"] objectForKey:@"alert"]); 19 if ([[userInfo objectForKey:@"aps"] objectForKey:@"alert"]!=NULL) { 20 UIAlertView* alert = [[UIAlertView alloc] initWithTitle:@"推送通知" 21 message:[[userInfo objectForKey:@"aps"] objectForKey:@"alert"] 22 delegate:self 23 cancelButtonTitle:@" 关闭" 24 otherButtonTitles:@" 更新状态",nil]; 25 [alert show]; 26 [alert release]; 27 } 28 }

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

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：

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

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

5）如果需要对 key不进行加密：
  

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。
  

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'; 2 $pass = '123456'; // Passphrase for the private key (ck.pem file) 3 4 // Get the parameters from http get or from command line 5 $message = $_GET['message'] or $message = $argv[1] or $message = 'A test message from worldcup'; 6 $badge = (int)$_GET['badge'] or $badge = (int)$argv[2]; 7 $sound = $_GET['sound'] or $sound = $argv[3]; 8 9 // Construct the notification payload 10 $body = array(); 11 $body['aps'] = array('alert' => $message); 12 if ($badge) 13 $body['aps']['badge'] = $badge; 14 if ($sound) 15 $body['aps']['sound'] = $sound; 16 17 /* End of Configurable Items */ 18 $ctx = stream_context_create(); 19 stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem'); 20 // assume the private key passphase was removed. 21 stream_context_set_option($ctx, 'ssl', 'passphrase', $pass); 22 23 // connect to apns 24 $fp = stream_socket_client('ssl://gateway.sandbox.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT, $ctx); 25 if (!$fp) { 26 print "Failed to connect $err $errstr\n"; 27 return; 28 } 29 else { 30 print "Connection OK\n 31 "; 32 } 33 34 // send message 35 $payload = json_encode($body); 36 $msg = chr(0) . pack("n",32) . pack('H*', str_replace(' ', '', $deviceToken)) . pack("n",strlen($payload)) . $payload; 37 print "Sending message :" . $payload . "\n"; 38 fwrite($fp, $msg); 39 fclose($fp); 40 ?>

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：

Connection OK 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。
