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:

 
 

 
 
<?php  


 
 
$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<br/>";  


 
 
}  


 
// 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。
