remote notification on ios - php

Question

I'm trying to send a remote notification from own php server to app.
Here's the code in AppDelefate.m:
#import "AppDelegate.h"
#import <UserNotifications/UserNotifications.h>
#interface AppDelegate ()
#end
#implementation AppDelegate
#define SYSTEM_VERSION_GRATERTHAN_OR_EQUALTO(v) ([[[UIDevice currentDevice] systemVersion] compare:v options:NSNumericSearch] != NSOrderedAscending)
-(BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions{
[self registerForRemoteNotifications];
return YES;
}
- (void)registerForRemoteNotifications {
UNUserNotificationCenter *center = [UNUserNotificationCenter currentNotificationCenter];
center.delegate = self;
[center requestAuthorizationWithOptions:(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge) completionHandler:^(BOOL granted, NSError * _Nullable error){
if(!error){
[[UIApplication sharedApplication] registerForRemoteNotifications];
}
}];
}
//Called when a notification is delivered to a foreground app.
-(void)userNotificationCenter:(UNUserNotificationCenter *)center willPresentNotification:(UNNotification *)notification withCompletionHandler:(void (^)(UNNotificationPresentationOptions options))completionHandler{
NSLog(#"User Info : %#",notification.request.content.userInfo);
completionHandler(UNAuthorizationOptionSound | UNAuthorizationOptionAlert | UNAuthorizationOptionBadge);
}
//Called to let your app know which action was selected by the user for a given notification.
-(void)userNotificationCenter:(UNUserNotificationCenter *)center didReceiveNotificationResponse:(UNNotificationResponse *)response withCompletionHandler:(void(^)())completionHandler{
NSLog(#"User Info : %#",response.notification.request.content.userInfo);
completionHandler();
}
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo {
NSLog(#"%#", userInfo);
}
- (void)application:(UIApplication *)application didReceiveRemoteNotification:(NSDictionary *)userInfo
fetchCompletionHandler:(void (^)(UIBackgroundFetchResult))completionHandler {
NSLog(#"%#", userInfo);
completionHandler(UIBackgroundFetchResultNewData);
}
- (void)applicationDidFinishLaunching:(UIApplication *)app {
[[UIApplication sharedApplication] registerForRemoteNotifications];
}
// Handle remote notification registration.
- (void)application:(UIApplication *)app
didRegisterForRemoteNotificationsWithDeviceToken:(NSData *)devToken {
NSString *token = [[devToken description] stringByTrimmingCharactersInSet: [NSCharacterSet characterSetWithCharactersInString:#"<>"]];
token = [token stringByReplacingOccurrencesOfString:#" " withString:#""];
NSLog(#"content---%#", token);
}
- (void)application:(UIApplication *)app
didFailToRegisterForRemoteNotificationsWithError:(NSError *)err {
NSLog(#"Remote notification support is unavailable due to error: %#", err);
}
- (void)applicationWillResignActive:(UIApplication *)application {
}
- (void)applicationDidEnterBackground:(UIApplication *)application {
}
- (void)applicationWillEnterForeground:(UIApplication *)application {
}
- (void)applicationDidBecomeActive:(UIApplication *)application {
}
- (void)applicationWillTerminate:(UIApplication *)application {
}
#end
When I run the app, it ask for notification privilege, after accepted. Console print the following token:
content---13eeb8d33de4f0ba55f520469f9b0970e973faa6904a38428b2193b04ac3782b
So I use this token in my PHP server for testing:
<?php
// Put your device token here (without spaces):
$deviceToken = '13eeb8d33de4f0ba55f520469f9b0970e973faa6904a38428b2193b04ac3782b';
// Put your private key's passphrase here:
$passphrase = 'xoxoxo';
// Put your alert message here:
$message = 'Test push.';
$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', 'BDSPKCertificates.pem');
stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);
var_dump($ctx);
// Open a connection to the APNS server
$apns = stream_socket_client('ssl://gateway.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT, $ctx); // production
echo "<p>Open Connection</p>";
if(!$apns)
{
echo "<p>Failed to connect!<br />Error Number: " . $err . " <br />Code: " . $errstr . "</p>";
return;
}
else
{
echo "<p>Connected</p>";
// Create the payload body
$body = array();
$body['aps'] = array(
"title"=>"Test title",
'alert' => $message,
'sound' => 'default',
'badge' => 1
);
// Encode the payload as JSON
$payload = json_encode($body);
echo "<p>Message: ";
print_r($payload);
echo "</p>";
// Build the binary notification
$msg = chr(0) . pack("n",32) . pack('H*',str_replace(' ', '', $deviceToken)) . pack ("n", strlen($payload)) . $payload;
// Send it to the server
$result = fwrite($apns, $msg, strlen($msg));
if (!$result)
{
echo 'Message not delivered' . PHP_EOL;
}
else
{
echo 'Message successfully delivered' . PHP_EOL;
}
// Close the connection to the server
fclose($apns);
}
?>
When i run this PHP code, it prints the following:
resource(2) of type (stream-context)
Open Connection
Connected
Message: {"aps":{"title":"Test title","alert":"Test push.","sound":"default","badge":1}}
Message successfully delivered
However my app receive nothing. Please help me to find what is missing in my codes. Thanks.

Answer 1

please confirm, you have open 2195 port in server firewall. Apple push notification sent via 2195 port. So it should open.

Answer 2

I think you are using sandbox environment but in your PHP script your socket client is production, use sandbox for development like below.
Sandbox
ssl://gateway.sandbox.push.apple.com:2195'
// Open a connection to the APNS server
$apns = stream_socket_client('ssl://gateway.sandbox.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT, $ctx); // sandbox
Production
ssl://gateway.push.apple.com:2195'
// Open a connection to the APNS server
$apns = stream_socket_client('ssl://gateway.push.apple.com:2195', $err, $errstr, 60, STREAM_CLIENT_CONNECT, $ctx); // production
