iPhone應(yīng)用中APNS推送通知流程代碼

iPhone應(yīng)用中APNS推送通知流程代碼實(shí)現(xiàn)案例是本文要介紹的內(nèi)容，主要是如何來實(shí)現(xiàn)APNS的推送通知，具體內(nèi)容來看本文詳細(xì)代碼。

1. 將app注冊notification里面, 并從APNS上獲取測試機(jī)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:@" 關(guān)閉"

otherButtonTitles:@" 更新狀態(tài)",nil];

[alert show];

[alert release];

}

}

啟動程序，將app注冊到通知項(xiàng)后，在console里面找到打印的deviceToken：

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

2、生成app在服務(wù)端需要的許可證

(1)進(jìn)入Provisioning Portal, 下載Certificates在development下的證書。

(2) 找到需要測試的app id,然后enable它在development下的Apple Push Notification service: Development Push SSL Certificate。需要輸入1)中的簽名證書才可以生成一個(gè)aps_developer_identity.cer.

(3) 雙擊aps_developer_identity.cer，會打開系統(tǒng)的key chain. 在My certificates下找到Apple Development Push Services。需要為certificate和它之下的private key各自export出一個(gè).p12文件。(會出現(xiàn)設(shè)置密碼過程)

(4)需要將上面的2個(gè).p12文件轉(zhuǎn)成.pem格式：

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

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

(5)如果需要對 key不進(jìn)行加密：

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

(6)然后就可以 合并兩個(gè).pem文件, 這個(gè)ck.pem就是服務(wù)端需要的證書了。

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

3、服務(wù)端push通知到ANPS. 在cocoachina找到了兩種方法:

(1)php驅(qū)動。需要將ck.pem和php腳本放到server 上。全部的php代碼是：

$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://#: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);

?>

請 求一次 http://127.0.0.1/apns /apns.php?message=A%20test%20message%20from%20localhost&badge=2& sound=received5.caf就 會向APNS進(jìn)行一次推送。我的請求結(jié)果如下：

Connection OK

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

(2)pushMeBaby 驅(qū)動。將aps_developer_identity.cer導(dǎo)入到project里面，改名為apns.cer。

小結(jié)：iPhone應(yīng)用中APNS推送通知流程代碼實(shí)現(xiàn)案例的內(nèi)容介紹完了，希望通過本文的學(xué)習(xí)能對你有所幫助!
