android - ios和android推送通知到多个设备

Question

我真的很苦恼这个问题。这段代码不是我创建的，但我对其进行了更改，因此它可以工作。我的目标是让它能够向使用该应用程序的所有设备发送推送通知。我是一个ios和andriod编程者，所以我会尽力而为。我已经清理并更改了提供给我的代码，以便它现在仅向一台设备发送通知。

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 ) );

我将 ios 设备 token 添加到 $deviceToken，将 android 设备 token 添加到 $regi，它将发送到手机。我唯一改变的部分是苹果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 $dev 变量，而 Android 使用 $regi。现在我知道设备 token 在应用程序启动时被发送到服务器，所以我猜测它们没有存储在变量中。您可以看到任何问题吗？我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，但我会与其他正在苦苦挣扎的人分享。

<?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');";

问题似乎是应用程序正在向数据库发送开发设备 token ，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，它会向我的数据库发送一个 0 的设备 token ，如果使用它会停止发送通知。所以我在我的 php 文件中对我的设备 token 进行排序的地方我添加了更多逻辑来忽略所有只有 0 的 token 。

在我将它添加到我的 $ios 数组之前，我只是简单地检查了长度是否超过 25 个字符，而之前我没有这样做

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 apples 生产推送通知服务器发送的设备 token 不是有效的生产设备 token ，它就不会向任何设备发送通知。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 token 。

希望这对人们有所帮助。
