如果互联网关闭，GCM不能发送

问题描述

为什么如果通知开始时接收器的互联网无效然后它会打开通知neve r到达？对不起，我的英语

这里是我的php：

 < 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）; 
 $授权='AIzaSyBfrXTHDg_TDoD1dKgoSbeTNH2heV_aq30'; 
 $ headers = array（
'Authorization：key ='。$ Authorization，
'Content-Type：application / json'
）; 
 
 
 $ fields = array（
'delay_while_idle'=> true，
'time_to_live'=> 2419200，
'registration_ids'=> ;数组（$ = $ api），
'data'=>数组（
'type'=>$ type，
'id'=>$ id，
'mittente'=>$ mittente，
'data'=>$ data
），
）; 
 print_r（$ fields ['data']）; 
 echo sendNotification（$ headers，$ fields）; 
 
函数sendNotification（$ h，$ f）{
 
 //设置POST变量
 $ url ='https://android.googleapis.com/gcm /发送'; 
 
 //打开连接
 $ ch = curl_init（）; 
 
 //设置网址，POST变量的数量，POST数据
 curl_setopt（$ ch，CURLOPT_URL，$ url）; 
 
 curl_setopt（$ ch，CURLOPT_POST，true）; 
 curl_setopt（$ ch，CURLOPT_HTTPHEADER，$ h）; 
 curl_setopt（$ ch，CURLOPT_RETURNTRANSFER，true）; 
 
 curl_setopt（$ ch，CURLOPT_POSTFIELDS，json_encode（$ f））; 
 
 //执行后
 $结果= curl_exec（$ ch）; 
 echo $ result; 
 //关闭连接
 curl_close（$ ch）; 
 
返回$ result; 
 
 
函数getCode（$ ricevente）{
 $ myconn = connectToDatabase（）; 
 $ sql =来自用户的选择* WHERE手机='$ ricevente'; 
 $ result = mysqli_query（$ myconn，$ sql）; 
 if（$ result）{
 $ row = mysqli_fetch_array（$ result）; 
 mysqli_close（$ myconn）; 
返回$ row ['api']; 
} 
 $ phone2 =''; 
 if（$ ricevente [0] =='+'）{
 $ phone2 = substr（$ ricevente，3，strlen（$ ricevente））; 
 
} 
 else {
 $ phone2 =+39。$ ricevente; 
} 
 $ sql =从用户选择* WHERE phone ='$ phone2'; 
 $ result = mysqli_query（$ myconn，$ sql）;

请帮助我，因为我不知道他们为什么会注意送货

$ b $ 部分讨论了为什么它可能未被交付的几个因素。基本上，GCM连接的空闲设备将立即交付，除非 delay_while_idle 设置为true。未连接到GCM的设备将存储在服务器中，直到建立连接。

另外，请不要忘记清单。

Why if internet of receiver when notification start is inactive And Then It Will turned on the notification neve r arrived? Sorry for My English

Please help me because i don't know why they will note delivery

解决方案

The lifetime of a message section of the GCM documentation discusses several factors as to why it may not have been "delivered"

Basically, a GCM-connected device that's idle will be delivered right away unless delay_while_idle is set to true. A device not connected to GCM will be stored in the server until a connection has been established.

Also, don't forget to obtain a registration token for the client app for your Instance Service in your manifest.

这篇关于如果互联网关闭，GCM不能发送的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！
