【问题描述】：

我真的很挣扎。这段代码不是由我创建的，但我已经更改了它，所以它有点工作。我的目标是让它能够向所有使用该应用程序的设备发送推送通知。我是一个ios和andriod编程的，所以我会尽力而为。我已经清理并更改了提供给我的代码，以便它现在只向一个设备发送通知。

这是代码

<?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';

?>

我将 ios 设备令牌添加到 $deviceToken 并将 android 设备令牌添加到 $regi，它将发送到手机。我唯一更改的部分是 Apple 推送通知部分不起作用。在我更改它之前，苹果推送通知使用的是 $dev 变量，而 android 使用的是 $regi。现在我知道启动应用程序时设备令牌正在发送到服务器，所以我的猜测是它们没有存储在变量中。您是否可以看到任何问题以及如何打印它们以查看它们是否为空？

谢谢

我不久前就想到了这一点，尽管我会分享给其他正在苦苦挣扎的人。

<?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[] = $row['device_token'];
                $dev = $row['device_token'];

                if( strlen ( $dev ) > 65 ) {
                    $regis[] = $row['device_token'];
                } 
                else if ( strlen ($dev) > 25 ) {

                }

        $deviceToken=$_REQUEST['device'];
        $json=json_decode($deviceToken);

        //google Push notification

        // API access key from Google API's Console
        define( 'API_ACCESS_KEY', 'AIzaSyCMysH7TySEgdbvRoCLoZk8uFF1x_A3uxg' );

        stream_context_set_option($ctx, 'ssl', 'passphrase', $passphrase);

        // Encode the payload as JSON

        // Loop though device tokens
        foreach($ios as $dev) {
            if($dev!=''){
                // Build the binary notification
                $msg = chr(0) . pack('n', 32) . pack('H*', $dev) . pack('n', strlen($payload)) . $payload;
                //Send it to the server

            }
        }

        if (!$result)
            echo 'Message not delivered' . PHP_EOL;

        // Close the connection to the server
        fclose($fp);

        include 'index.php';
    }

?>

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
}

我还发现，如果用户拒绝允许推送通知的请求，它将向我的数据库发送 0 的设备令牌，如果使用它会停止发送通知。因此，在我在我的 php 文件中对设备令牌进行排序的地方，我添加了更多逻辑来忽略所有只有 0 的令牌。

在将其添加到我的 $ios 数组之前，我只是检查了长度是否超过 25 个字符，而之前我没有

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，如果您向苹果生产推送通知服务器发送一个不是有效生产设备令牌的设备令牌，它只是不会将通知发送到任何设备。这就是为什么我它不起作用的原因，我在我的 php 代码和 Objective-c 代码中添加了额外的逻辑，以过滤掉所有无效的设备令牌。

希望这对人们有所帮助。
