Apple Push Nofification service SSL Certificates

iOS App 有內建的推播可以用, 首先要設定App 允許推播. 前置準備是要弄一台 Apache + Php 來送資料到 Apple.

Step 1: 進入 iOS Developer Center, 點 Cerfificates

Step 2: 點 "Edit"

Step 3: Push Notifications 打勾

Step 4: 按下面的步驟可以產生 CSR, 產生好後按 "Continue"

Step 5: 上傳 CSR 檔案，並按下 Generate

Step 6: 下載certificate

說明：　這個 certificates 分 development 和 product, develop 的好像３個月會過期，要重新 generate 並 download 一次．


Q: Step 5: 上傳 CSR 檔案，並按下 Generate
development跟product需要從分別不同的CSR嗎？還是同一個CSR就可以了 A: 還是同一個CSR就可以了 .


接下來的步驟，只能在 Mac 上執行．接棒給Mac.
(其實: 從頭到尾通通在 Mac 上做就ok了.)
＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝＝

Step 7: 進入  keychain 匯出 Push Services key 為 .p12 的檔案

（有2種，Development & Production 的 certificates, 有要測 development  的話請匯出2次。 )



Step 8: Save as 輸入檔名，點  "Save"

輸入  password

Step 9: 產生 pem 檔案：
openssl pkcs12 -clcerts -nokeys -out cert.pem -in ios_push_cert.p12
openssl pkcs12 -nocerts -out key.pem -in ios_push_cert.p12
openssl rsa -in key.pem -out key.unencrypted.pem
cat cert.pem key.unencrypted.pem > ck.pem

production指令範例：
openssl pkcs12 -clcerts -nokeys -out cert_production.pem -in ios_push_cert_production.p12
openssl pkcs12 -nocerts -out key_production.pem -in ios_push_cert_production.p12
openssl rsa -in key_production.pem -out key.unencrypted_production.pem
cat cert_production.pem key.unencrypted_production.pem > ck_production.pem


測試 sandbox push server 是否可以被連到：
telnet gateway.sandbox.push.apple.com 2195

測試 sandbox push server 是否可以使用 SSL 憑證連到：
openssl s_client -connect gateway.sandbox.push.apple.com:2195 -cert pushtestcert.pem -key pushtestkey.pem

xcode 裡的程式碼：

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions

{

    NSLog(@"Registeringfor push notifications...");

    [[UIApplication sharedApplication]

     registerForRemoteNotificationTypes:

     (UIRemoteNotificationTypeAlert |

      UIRemoteNotificationTypeBadge |

      UIRemoteNotificationTypeSound)];

    

    return YES;

}

- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {

    NSString *str = [NSString

                     stringWithFormat:@"%@",deviceToken];

    NSLog(@"Device Token:%@",str);

}

- (void)application:(UIApplication*)application didFailToRegisterForRemoteNotificationsWithError:(NSError *)err

{

    NSLog(@"didFailToRegisterForRemoteNotificationsWithError:%@",[err description]);

}

- (void)application:(UIApplication*)application didReceiveRemoteNotification:(NSDictionary *)userInfo

{

    /*

    for (id key in userInfo) {

        NSLog(@"key: %@, value: %@", key, [userInfo objectForKey:key]);

    }

     */

    NSDictionary *apsInfo = [userInfo objectForKey:@"aps"];

    

    NSString *alertMsg = @"";

    NSInteger badge = 0;

    NSString *sound = @"";

    NSString *custom = @"";

    

    if( [apsInfo objectForKey:@"alert"] != NULL)

    {

        alertMsg = [apsInfo objectForKey:@"alert"];

    }

    

    

    if( [apsInfo objectForKey:@"badge"] != NULL)

    {

        badge = [[apsInfo objectForKey:@"badge"] integerValue];

    }

    if(badge>0)

    {

        // reset badge counter.

        int currentBadgeNumber = [UIApplication sharedApplication].applicationIconBadgeNumber;

        currentBadgeNumber += badge;

        [UIApplication sharedApplication].applicationIconBadgeNumber = currentBadgeNumber;

    }

    

    

    if( [apsInfo objectForKey:@"sound"] != NULL)

    {

        sound = [apsInfo objectForKey:@"sound"];

    }

    

    if( [userInfo objectForKey:@"Custom"] != NULL)

    {

        custom = [userInfo objectForKey:@"Custom"];

    }

}

php 的範例：

<?php

// Put your device token here (without spaces):修改點1
$deviceToken = '740f4707bebcf74f9b7c25d48e3358945f6aa01da5ddb387462c7eaf61bb78ad';

// Put your private key's passphrase here:修改點2
$passphrase = 'passowrd';

// Put your alert message here:修改點3
$message = 'My first push notification!';

////////////////////////////////////////////////////////////////////////////////

$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.pem');修改點4 *.pem
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);

// Open a connection to the APNS server
$fp = stream_socket_client(
 'ssl://gateway.sandbox.push.apple.com:2195', $err,
 $errstr, 60, STREAM_CLIENT_CONNECT|STREAM_CLIENT_PERSISTENT, $ctx);

if (!$fp)
 exit("Failed to connect: $err $errstr" . PHP_EOL);

echo 'Connected to APNS' . PHP_EOL;

// Create the payload body
$body['aps'] = array('alert' => $message,'sound' => 'default');

// Encode the payload as JSON
$payload = json_encode($body);

// Build the binary notification
$msg = chr(0) . pack('n', 32) . pack('H*', $deviceToken) . pack('n', strlen($payload)) . $payload;

// Send it to the server
$result = fwrite($fp, $msg, strlen($msg));

if (!$result)
 echo 'Message not delivered' . PHP_EOL;
else
 echo 'Message successfully delivered' . PHP_EOL;

// Close the connection to the server
fclose($fp);
