无法使用 PHP 作为后端获取通知

Question

我是Android的新手，我创建了一个程序，该程序将使用Firebase发送通知，而无需使用Firebase控制台。我使用 php 作为后端，令人高兴的是，我只有在通过 firebase 控制台发送时才会收到通知，但是当我通过 wamp 服务器发送它时，我不能。

索引.php

error_reporting(-1);
ini_set('display_errors', 'On');
require_once __DIR__ . '/firebase.php';
require_once __DIR__ . '/push.php';
$firebase = new Firebase();
$push = new Push();
// optional payload
$payload = array();
$payload['title'] = 'Notification!';
$payload['message'] = 'New PickupListed';
// notification title
$title = isset($_GET['title']) ? $_GET['title'] : '';
// notification message
$message = isset($_GET['message']) ? $_GET['message'] : '';
// push type - single user / topic
$push_type = isset($_GET['push_type']) ? $_GET['push_type'] : '';
// whether to include to image or not
$include_image = isset($_GET['include_image']) ? TRUE : FALSE;

$push->setTitle($title);
$push->setMessage($message);
if ($include_image) {
$push->setImage('http://api.androidhive.info/images/minion.jpg');
} else {
$push->setImage('');
}  
$push->setIsBackground(FALSE);
$push->setPayload($payload);
$json = '';
$response = '';
if ($push_type == 'topic') {
$json = $push->getPush();
$response = $firebase->sendToTopic('global', $json);
} else if ($push_type == 'individual') {
$json = $push->getPush();
$regId = isset($_GET['regId']) ? $_GET['regId'] : '';
$response = $firebase->send($regId, $json);
}

但是我得到这个作为输出：仍然没有收到通知

Request:
{"data":{"title":"hey all","is_background":false,"message":"demo","image":"","timestamp":"2017-07-27 12:22:41"}}

Response:
"{"multicast_id":8934845196536440484,"success":1,"failure":0,"canonical_ids":0,"results":[{"message_id":"0:1501158164597153%293f606ef9fd7ecd"}]}"

Answer 1

1(尝试为优先级设置一个参数。

// optional payload
$payload = array();
$payload['title'] = 'Notification!';
$payload['message'] = 'New PickupListed';
$payload['priority'] = 'High';

请不要松散地使用它，以防它起作用。您还可以创建一个函数来定义脚本中需要立即传递的消息的优先级(高(，而不是"当应用进入前台时，它可以等待处理数据"(正常(。

2( 您正在构建数据消息。后台进程的处理在 Android 上发生了变化。您需要在收到消息后的 10 秒内完成数据处理，否则消息可能无法执行。

请参阅官方示例了解更多信息。 现在在您的 handleDataMessage 中，它可能不是长时间运行的进程，但可能仍需要 10 秒以上的时间来处理。最好的办法是进行分析，看看是否需要以更优化的方式安排某些事情或处理数据。

最佳实践：- 数据消息传递
应仅用于将某些数据传递给客户端，这些数据对于发送以更新应用程序数据、重置警报/计时器等至关重要
- 如果您的音量/频率较高，则不应为每个请求使用高优先级，因为高优先级会唤醒睡眠设备以传递消息，这可能会导致大量电池消耗。您的用户可能会觉得应用消耗了太多资源，可能会卸载或禁用通知。
