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)

  iPhone应用中APNS推送通知流程代码实现案例是本文要介绍的内容,主要是如何来实现APNS的推送通知,具体内容来看本文详细代码。

  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:

  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:

  

  $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 $errstrn";

  return;

  }

  else {

  print "Connection OKn
";

  }

  // 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 . "n";

  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:

  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。
