iOS推送消息实现

向iPhone、iPod Touch发送消息都需要认证的，下面是以向iPhone推送消息：

一、开通“Apple Push Notification Service”

1.进入 Provisioning Protal

2.选择App IDs

3.选择要开通“Apple Push Notification service”的AppID，点击“Configure”链接

4.点击“Enable for Apple Push Notification service”复选框

5.点击“Configure”按钮，选择CSR文件上传

6.点击“Download”按钮，下载CER文件，双击导入。

7.选择“Provisioning”，重新生成Provisioning Profile，下载，导入到XCode。

二、生成PHP端推送消息到Apple服务器时需要的证书文件

1.选定推送服务证书(Apple Development Push Services*),导出到桌面,保存为Certificates.p12。

2.在终端中运行如下命令:

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文件则是PHP推送消息时所使用的证书文件。

三、iPhone中获取DeviceToken代码

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]>

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
