分享一個搭建php版push伺服器的流程

初學iPhone 開發 ,經過反複多次驗證,結合下面2個教程:

得出從零開始的php版push伺服器搭建流程:

==============================================================

0.在Mac OS X機器上安裝好XCode , 連接配接一台正常的iPhone, 保持平和的心态

APP 開發基礎設定

1.在iPhone Provisioning Portal中建立好APP ID和Device.

2. 在Keychain Access.app中生成證書請求CertificateSigningRequest.certSigningRequest(菜單 > Keychain Access > Certificate Assistant > Request a Certificate From a Certificate Authority...).

3.在iPhone Provisioning Portal > Certificates中請求一個證書(點選Request Certificate,上傳CertificateSigningRequest.certSigningRequest).

4.請求完成後,将證書檔案 (developer_identity.cer)下載下傳,輕按兩下導入到Key Chain中.

5.在iPhone Provisioning Portal > Provisioning 中,建立一個Profile, 選擇指定的APP ID和 Devices後生成.

6.将剛剛生成的Profile下載下傳為*_profile.mobileprovision, 輕按兩下該檔案, 将profile加載到iPhone中.

Push Notification service設定

7.在iPhone Provisioning Portal > App IDs,選擇需要Push服務的App ID, 進入Configure.

8.确認 Enable for Apple Push Notification service ,配置 Development Push SSL Certificate, 上傳 第2步生成的證書請求.

9.下載下傳生成的aps_developer_identity.cer, 完成Push服務配置.

10.輕按兩下aps_developer_identity.cer,儲存到Key Chain.

生成php Push Notification sender需要的證書檔案

11.在Keychain Access.app裡標明這個新證書(Apple Development Push Services*),導出到桌面,儲存為Certificates.p12.

12.運作如下指令:

複制代碼     openssl pkcs12 -clcerts -nokeys -out cert.pem -in Certificates.p12     openssl pkcs12 -nocerts -out key.pem -in Certificates.p12     openssl rsa -in key.pem -out key.unencrypted.pem     cat cert.pem key.unencrypted.pem > ck.pem

獲得php Push Notification sender所需的裝置令牌:

13.建立一個View-based Application項目,在$PROJECT_NAMEAppDelegate.m中:

a.粘貼如下代碼 :

複制代碼 - (void)applicationDidFinishLaunching:(UIApplication *)app {     // other setup tasks here….     [window addSubview:viewController.view];     [self alertNotice:@"" withMSG:@"Initiating Remote Noticationss Are Active" cancleButtonTitle:@"Ok" otherButtonTitle:@""];     [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge |UIRemoteNotificationTypeSound)]; } - (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {     //NSLog(@"devToken=%@",deviceToken);     [self alertNotice:@"" withMSG:[NSString stringWithFormat:@"devToken=%@",deviceToken] cancleButtonTitle:@"Ok" otherButtonTitle:@""]; } - (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err {     NSLog(@"Error in registration. Error: %@", err);     [self alertNotice:@"" withMSG:[NSString stringWithFormat:@"Error in registration. Error: %@", err] cancleButtonTitle:@"Ok" otherButtonTitle:@""]; } -(void)alertNotice:(NSString *)title withMSG:(NSString *)msg cancleButtonTitle:(NSString *)cancleTitle otherButtonTitle:(NSString *)otherTitle{     UIAlertView *alert;     if([otherTitle isEqualToString:@""])         alert = [[UIAlertView alloc] initWithTitle:title message:msg delegate:self cancelButtonTitle:cancleTitle otherButtonTitles:nil,nil];     else         alert = [[UIAlertView alloc] initWithTitle:title message:msg delegate:self cancelButtonTitle:cancleTitle otherButtonTitles:otherTitle,nil];     [alert show];     [alert release]; }

b.在 - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions { 方法中增加

複制代碼     [self alertNotice:@"" withMSG:@"Initiating Remote Noticationss Are Active" cancleButtonTitle:@"Ok" otherButtonTitle:@""];     [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge |UIRemoteNotificationTypeSound)];

14.項目設定

a.Targets > $APP_NAME > context menu > Properties > Identifier

    修改 identifier 為App ID

b.Targets > $APP_NAME > context menu > Build > Code Signing > Code Signing Identifier > Any iPhone OS Device

    指定 iPhone Developer 為開發用機

15.編譯并運作後會在iPhone上顯示裝置令牌

16.php Push Notification sender代碼如下:

複制代碼 <?php $deviceToken = "裝置令牌"; $body = array("aps" => array("alert" => 'message', "badge" => 1, "sound" => 'received5.caf')); $ctx = stream_context_create(); stream_context_set_option($ctx, "ssl", "local_cert", "ck.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 $errstrn";     return; } print "Connection OK/n"; $payload = json_encode($body); $msg = chr(0) . pack("n",32) . pack("H*", $deviceToken) . pack("n",strlen($payload)) . $payload; print "sending message :" . $payload . "/n"; fwrite($fp, $msg); fclose($fp); ?>

==============================================================

希望各位高手能指正這流程中遺漏或不清楚的地方.

第一個問題:

我知道 Push 服務實際上是向APNS發送一個附帶證書的ssl請求, 由APNS來通知iPhone.

上面例子中,php發送請求時将裝置令牌和證書一并發送給APNS,我想知道有沒有辦法能更輕松的得到裝置令牌.

答案:裝置令牌 由你的app部署到用戶端後 上傳到伺服器獲得.

第二個問題:

如果我的APP釋出之後,要在 iPhone Provisioning Portal 中啟用 Production Push SSL Certificate(開發時用的是Development Push SSL Certificate),

這兩種證書狀态時的令牌是一樣的麼.

如果我同時啟用了兩個證書, php給APNS發請求時,APNS會接受哪一個呢?

答案:這2個證書 對的是2個apns 伺服器 開發的是開發的 正式的是正式的. 2個鎖2個鑰匙.不會同時有效
