iOS推送消息實現

向iPhone、iPod Touch發送消息都需要認證的，下面是以向iPhone推送消息：

一、開通“Apple Push Notification Service”

1.進入 Provisioning Protal

2.選擇App IDs

3.選擇要開通“Apple Push Notification service”的AppID，點擊“Configure”鏈接

4.點擊“Enable for Apple Push Notification service”複選框

5.點擊“Configure”按鈕，選擇CSR文件上傳

6.點擊“Download”按鈕，下載CER文件，雙擊導入。

7.選擇“Provisioning”，重新生成Provisioning Profile，下載，導入到XCode。

二、生成PHP端推送消息到Apple服務器時需要的證書文件

1.選定推送服務證書(Apple Development Push Services*),導出到桌面,保存爲Certificates.p12。

2.在終端中運行如下命令:

1. openssl pkcs12 -clcerts -nokeys -out cert.pem -in Certificates.p12  
2. openssl pkcs12 -nocerts -out key.pem -in Certificates.p12  
3. openssl rsa -in key.pem -out key.unencrypted.pem  
4. cat cert.pem key.unencrypted.pem > ck.pem

ck.pem文件則是PHP推送消息時所使用的證書文件。

三、iPhone中獲取DeviceToken代碼

1. - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

[[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge |UIRemoteNotificationTypeSound)];
}
- (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err {
[self alertNotice:@"" withMSG:[NSString stringWithFormat:@"Error in registration. Error: %@", err] cancleButtonTitle:@"Ok" otherButtonTitle:@""];
}
- (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
NSLog(@"devToken=%@",deviceToken);
[self alertNotice:@"" withMSG:[NSString stringWithFormat:@"devToken=%@",deviceToken] cancleButtonTitle:@"Ok" otherButtonTitle:@""];
}

Subject: Not receiving apns feedback response

From: JP <[email protected]>

To: Easy APNs <[email protected]>

Hi All,

I am not receiving any feedback after sending the push notification

though all the result messages confirm the connection to the feedback

server. Pl check the following php code that I have used and help, if

you have any clue:

--------apns.php----------

    <?php

    $deviceToken = '64 characters device token id'; // masked for

security reason

    $message = $_GET['message'] or $message = $argv[1] or $message =

'Dummy Notification';

    $badge = (int)$_GET['badge'] or $badge = (int)$argv[2];

    $sound = $_GET['sound'] or $sound = $argv[3];

    $body = array();

    $body['aps'] = array('alert' => $message);

    if ($badge)

    $body['aps']['badge'] = $badge;

    if ($sound)

    $body['aps']['sound'] = $sound;

    $ctx = stream_context_create();

    $t = stream_context_set_option($ctx, 'ssl', 'local_cert',

'New_cert/cert.pem');

$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\n";

    return;

    }

    else {

    print "Connection OK\n";

    }

    $payload = json_encode($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);

    ?>

-------------------------------------

--------feedback.php----------

    <?php

    $ctx = stream_context_create();

    stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem');

    stream_context_set_option($ctx, 'ssl', 'verify_peer', false);

    $fp = stream_socket_client('ssl://feedback.sandbox.push.apple.com:

2196', $error, $errorString, 60, STREAM_CLIENT_CONNECT, $ctx);

    if (!$fp) {

    print "Failed to connect feedback server: $err $errstr\n";

    return;

    }

    else {

    print "Connection to feedback server OK\n";

    }

    print "APNS feedback results\n";

    while ($devcon = fread($fp, 38))

    {

    $arr = unpack("H*", $devcon);

    $rawhex = trim(implode("", $arr));

    $feedbackTime = hexdec(substr($rawhex, 0, 8));

    $feedbackDate = date('Y-m-d H:i', $feedbackTime);

    $feedbackLen = hexdec(substr($rawhex, 8, 4));

    $feedbackDeviceToken = substr($rawhex, 12, 64);

    print "TIMESTAMP:" . $feedbackDate . "\n";

    print "DEVICE ID:" . $feedbackDeviceToken. "\n\n";

    }

    fclose($fp);

    ?>

-------------------------------------

The response that I am repeatedly receiving is as follows:

-----------Response------------

///////////////////////-iMac:APNS_NEW_CERTIFICATES ///////////////////

$

php -f apns.php "Dummy Notification" 2

             1Connection OK

sending message :{"aps":{"alert":"Dummy Notification","badge":2}}

Resource id #7Connection to feedback server OK

APNS feedback results

///////////////////////-iMac:APNS_NEW_CERTIFICATES ///////////////////

$

-------------------------------------

Pl check.

Thanks
