这里是我的php：

201  format (...)

这里是我的java代码

<?php include_once 'connection.php';

$myconn = connectToDatabase();
$ricevente = $_POST['ricevente'];
$mittente = $_POST['mittente'];
$type = $_POST['type'];
$id = $_POST['id'];
$data = $_POST['data'];
$api = getCode($ricevente);
$Authorization='AIzaSyBfrXTHDg_TDoD1dKgoSbeTNH2heV_aq30';

'Authorization: key=' .$Authorization ,
'Content-Type: application/json'
);


$fields = array(

请帮助我，因为我不知道为什么他们会记录交付

Answer 1

GCM文档的lifetime of a message部分讨论了为什么它可能没有“交付”的几个因素

基本上，除非delay_while_idle设置为true，否则将立即发送空闲的GCM连接设备。未连接到GCM的设备将存储在服务器中，直到建立连接为止。

此外，请不要忘记在清单中为您的实例服务的客户端应用obtain a registration token。

如果互联网关闭，GCM不会发送
