I am really struggling with this. This piece of code wasn't created by me but I have changed it so it sort of works. My goal is for it to be able to send push notifications to all devices that use the app. I am an ios and andriod programmed so I will try my best. I have cleaned up and changed the code that was given to me so that it will now send a notification to just one device.
This is the code
<?php
include 'conn.php';
if ( $_REQUEST['key'] == 'notification' ) {
include 'notifications.php';
$message = $_REQUEST['text'];
$text = mysql_real_escape_string( $_REQUEST['text'] );
$start = $_REQUEST['start'];
$end = $_REQUEST['end'];
$date = date( "Ymd", strtotime( $_REQUEST['date'] ) );
$callus = $_REQUEST['callus'];
$in = "INSERT INTO `notifications` (`date`, `start_time`, `end_time`, `text`, `call_us`) VALUES ('$date', '$start', '$end', '$text', '$callus');";
mysql_query($in);
} else {
$message = mysql_real_escape_string( $_REQUEST['text'] );
$time = date( 'Y-m-d H:i:s' );
$in = "INSERT INTO `alerts` (`text`, `time`) VALUES ('$message', '$time');";
mysql_query( $in );
$sel="SELECT * FROM `users` GROUP by device_token";
$rs = mysql_query( $sel ) or die('');
if ( mysql_num_rows( $rs ) != 0 ) {
while( $row=mysql_fetch_array( $rs ) ) {
$regi = array();
$regi[] = $row['device_token'];
$dev = $row['device_token'];
if( strlen ( $dev ) > 65 ) {
$regis[] = $row['device_token'];
} else {
$ios[] = $dev;
}
}
}
$url = 'https://android.googleapis.com/gcm/send';
$fields = array( 'registration_ids' => $regis, 'data' => array( 'message'=>$message,'count'=>1 ) );
$headers = array(
'Authorization: key=AIzaSyCMysH7TySEgdbvRoCLoZk8uFF1x_A3uxg',
'Content-Type: application/json'
);
$ch = curl_init();
curl_setopt( $ch, CURLOPT_URL, $url );
curl_setopt( $ch, CURLOPT_POST, true );
curl_setopt( $ch, CURLOPT_HTTPHEADER, $headers );
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
curl_setopt( $ch, CURLOPT_SSL_VERIFYPEER, false );
curl_setopt( $ch, CURLOPT_POSTFIELDS, json_encode ( $fields ) );
$result = curl_exec( $ch );
curl_close ( $ch );
//Apple Push notification
// This this a fake device id:
$deviceToken = "5d8b3165fc03645d23c2651badd69f07d028aee801acf1d25a4d230882156755";
// fake password:
$passphrase = '123456789';
$ctx = stream_context_create();
stream_context_set_option($ctx, 'ssl', 'local_cert', 'ck.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',
'badge' => '1'
);
// 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);
}
include 'index.php';
?>
I add the ios device token to the $deviceToken and the android device token to the $regi and it will send to the phones. The only part I have changed is the Apple push notification part which didn't work. Before I changed it the apple push notification was using the $dev variable and android was using $regi. Now I know that the device tokens are being sent to the server when the app is launched so my guess is that they are not being stored in the variables. Is there any problems you can see and how can I print them out to see if they are empty?
Thanks

我不久前想到了这一点，虽然我会分享其他任何正在挣扎的人。
<?php
include 'conn.php';
if ( $_REQUEST['key'] == 'notification' ) {
$message = $_REQUEST['text'];
$text = mysql_real_escape_string( $_REQUEST['text'] );
$start = $_REQUEST['start'];
$end = $_REQUEST['end'];
$date = date( "Ymd", strtotime( $_REQUEST['date'] ) );
$callus = $_REQUEST['callus'];
$in = "INSERT INTO `notifications` (`date`, `start_time`, `end_time`, `text`, `call_us`) VALUES ('$date', '$start', '$end', '$text', '$callus');";
mysql_query($in);
include 'notifications.php';
}
else {
$message = mysql_real_escape_string( $_REQUEST['text'] );
$time = date( 'Y-m-d H:i:s' );
$in = "INSERT INTO `alerts` (`text`, `time`) VALUES ('$message', '$time');";
mysql_query( $in );
$sel="SELECT * FROM `users` GROUP by device_token";
$rs = mysql_query( $sel ) or die('');
if ( mysql_num_rows( $rs ) != 0 ) {
while( $row=mysql_fetch_array( $rs ) ) {
$regi = array();
$regi[] = $row['device_token'];
$dev = $row['device_token'];
if( strlen ( $dev ) > 65 ) {
$regis[] = $row['device_token'];
}
else if ( strlen ($dev) > 25 ) {
$ios[] = $dev;
}
}
}
$deviceToken=$_REQUEST['device'];
$json=json_decode($deviceToken);
//google Push notification
// API access key from Google API's Console
define( 'API_ACCESS_KEY', 'AIzaSyCMysH7TySEgdbvRoCLoZk8uFF1x_A3uxg' );
//build the message
$fields = array
(
'registration_ids' => $regis,
'data' => array( 'message'=> $message,'count'=>1 )
);
$headers = array
(
'Authorization: key=' . API_ACCESS_KEY,
'Content-Type: application/json'
);
$ch = curl_init();
curl_setopt( $ch,CURLOPT_URL, 'https://android.googleapis.com/gcm/send' );
curl_setopt( $ch,CURLOPT_POST, true );
curl_setopt( $ch,CURLOPT_HTTPHEADER, $headers );

curl_setopt( $ch,CURLOPT_SSL_VERIFYPEER, false );

$result = curl_exec($ch );
curl_close( $ch );
//Apple Push notification

问题似乎是应用程序正在向数据库发送开发设备令牌，因此我将xcode中的didRegisterForRemoteNotificationsWithDeviceToken函数更新为：
- (void)application:(UIApplication*)application didRegisterForRemoteNotificationsWithDeviceToken:(NSData*)deviceToken{
#ifdef DEBUG
// Update the database with our development device token
NSLog(@"IN DEVELOPMENT MODE!!!!!!!");
#else
// Update the database with our production device token
NSString *token = [[deviceToken description] stringByTrimmingCharactersInSet: [NSCharacterSet characterSetWithCharactersInString:@"<>"]];
token = [token stringByReplacingOccurrencesOfString:@" " withString:@""];
NSLog(@"content---%@", token);
kSetValueForKey(@"device_token", token);
[self updateDeviceToken:token];
#endif
}
此外，我发现如果用户拒绝允许推送通知的请求，它会将设备令牌0发送到我的数据库，如果使用，则会停止发送通知。所以，我在我的php文件中对我的设备令牌进行排序时，我添加了更多逻辑来忽略所有只有0的令牌。
在我将它添加到我的$ ios数组之前，我只是检查了长度超过25个字符，之前我不是
旧代码：
if( strlen ( $dev ) > 65 ) {
$regis[] = $row['device_token'];
} else {
$ios[] = $dev;
}
新代码：
if( strlen ( $dev ) > 65 ) {
$regis[] = $row['device_token'];
} else if ( strlen ($dev) > 25 ) {
$ios[] = $dev;
}
我发现的一个主要问题是，如果您将设备令牌发送到不是有效生产设备令牌的苹果生产推送通知服务器，它只是不会将通知发送到任何设备。这就是为什么我没有工作，我在我的PHP代码和Objective-c代码中添加了额外的逻辑来过滤掉所有无效的设备令牌。
希望这有助于人们。
