push推送浅析

 前几天要做一个带push推送通知的项目，我很郁闷！因为之前没有做过相关的东西，于是就疯狂的在网上找教材，花了几天慢慢的对其有所了解了！

1.在iPhone Provisioning Portal中建立好APP ID和Device.
2. 在Keychain Access.app中生成证书请求CertificateSigningRequest.certSigningRequest(菜单 > Keychain Access > Certificate Assistant > Request a Certificate From a Certificate Authority...).
3.在iPhone Provisioning Portal > Certificates中请求一个证书(点击Request Certificate,上传CertificateSigningRequest.certSigningRequest).
4.请求完成后,将证书文件(developer_identity.cer)下载,双击导入到Key Chain中.
5.在iPhone Provisioning Portal > Provisioning 中,新建一个Profile, 选择指定的APP ID和 Devices后生成.
6.将刚刚生成的Profile下载为*_profile.mobileprovision, 双击该文件, 将profile加载到iPhone中.

Push Notification service设置
7.在iPhone Provisioning Portal > App IDs,选择需要Push服务的App ID, 进入Configure.
8.确认 Enable for Apple Push Notification service ,配置 Development Push SSL Certificate, 上传第2步生成的证书请求.
9.下载生成的aps_developer_identity.cer, 完成Push服务配置.
10.双击aps_developer_identity.cer,保存到Key Chain.

生成php Push Notification sender需要的证书文件
11.在Keychain Access.app里选定这个新证书(Apple Development Push Services*),导出到桌面,保存为Certificates.p12.
12.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

获得php Push Notification sender所需的设备令牌:

13.新建一个View-based Application项目,在$PROJECT_NAMEAppDelegate.m中:

a.粘贴如下代码:

   1. - (void)applicationDidFinishLaunching:(UIApplication *)app {
   2.     // other setup tasks here….
   3.     [window addSubview:viewController.view];
   4.     [self alertNotice:@"" withMSG:@"Initiating Remote Noticationss Are Active" cancleButtonTitle:@"Ok" otherButtonTitle:@""];
   5.     [[UIApplication sharedApplication] registerForRemoteNotificationTypes:(UIRemoteNotificationTypeAlert | UIRemoteNotificationTypeBadge |UIRemoteNotificationTypeSound)];
   6. }
   7. - (void)application:(UIApplication *)app didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)deviceToken {
   8.     //NSLog(@"devToken=%@",deviceToken);
   9.     [self alertNotice:@"" withMSG:[NSString stringWithFormat:@"devToken=%@",deviceToken] cancleButtonTitle:@"Ok" otherButtonTitle:@""];
10. }
11. - (void)application:(UIApplication *)app didFailToRegisterForRemoteNotificationsWithError:(NSError *)err {
12.     NSLog(@"Error in registration. Error: %@", err);
13.     [self alertNotice:@"" withMSG:[NSString stringWithFormat:@"Error in registration. Error: %@", err] cancleButtonTitle:@"Ok" otherButtonTitle:@""];
14. }
15. -(void)alertNotice:(NSString *)title withMSG:(NSString *)msg cancleButtonTitle:(NSString *)cancleTitle otherButtonTitle:(NSString *)otherTitle{
16.     UIAlertView *alert;
17.     if([otherTitle isEqualToString:@""])
18.         alert = [[UIAlertView alloc] initWithTitle:title message:msg delegate:self cancelButtonTitle:cancleTitle otherButtonTitles:nil,nil];
19.     else
20.         alert = [[UIAlertView alloc] initWithTitle:title message:msg delegate:self cancelButtonTitle:cancleTitle otherButtonTitles:otherTitle,nil];
21.     [alert show];
22.     [alert release];
23. }

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

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

14.项目设置
a.Targets > $APP_NAME > context menu > Properties > Identifier
    修改 identifier 为App ID

b.Targets > $APP_NAME > context menu > Build > Code Signing > Code Signing Identifier > Any iPhone OS Device
    指定 iPhone Developer 为开发用机

15.编译并运行后会在iPhone上显示设备令牌

16.php Push Notification sender代码如下:
   1. <?php
   2. $deviceToken = "设备令牌";
   3.  
   4. $body = array("aps" => array("alert" => 'message', "badge" => 1, "sound" => 'received5.caf'));
   5.  
   6. $ctx = stream_context_create();
   7. stream_context_set_option($ctx, "ssl", "local_cert", "ck.pem");
   8.  
   9. $fp = stream_socket_client("ssl://gateway.sandbox.push.apple.com:2195", $err, $errstr, 60, STREAM_CLIENT_CONNECT, $ctx);
10. if (!$fp) {
11.     print "Failed to connect $err $errstrn";
12.     return;
13. }
14. print "Connection OKn";
15. $payload = json_encode($body);
16. $msg = chr(0) . pack("n",32) . pack("H*", $deviceToken) . pack("n",strlen($payload)) . $payload;
17. print "sending message :" . $payload . "n";
18. fwrite($fp, $msg);
19. fclose($fp);
20. ?>
