iPhone消息推送服务实现

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。（很重要）

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:

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

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

- (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:@""];
}

四、项目设置

Targets > $APP_NAME > context menu > Properties > Identifier
修改 identifier 为App ID

五、PHP端推送消息代码

<?php
$deviceToken = "设备令牌";
$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);
?>

六、注意事项

1.DeviceToken要去掉-

2.发布版本使用“gateway.push.apple.com”
