将Firebase通知发送到多个注册的Android设备

Question

我想向Android设备的MySQL数据库中的所有注册令牌发送Firebase通知我发送通知非注册设备会收到它。我想知道是否需要添加一些PHP代码与Firebase一起使用，以便完成工作，如果是这样，我应该根据我的代码或在何处使用它，或者我的代码有什么问题以及如何使用我可以修复吗？

//这是发送通知的代码

 <?php
  $message =$_POST['message'];
     $title=$_POST['title'];
 //firebase server  url
  $path_to_fcm='https://fcm.googleapis.com/fcm/send';
  // Here is the server_key
   $server_key="##########################";
   $conn = mysqli_connect("localhost","db_username","password","database_name");
   $sql = "select * from fcm_info";
   $result = mysqli_query($conn,$sql);
  //HERE IS THE TOKEN 
$tokens = array();
if(mysqli_num_rows($result) > 0 ){
    while ($row = mysqli_fetch_assoc($result)) {
        $tokens[] = $row["fcm_token"];
    }
}
///  HERE IS THE KEY SINGLE RECIPIENT IT WORKS FINE WHEN I INTRODUCE TO THE      RECIPIENT FIELD("to" field)
$key="############";
 $headers= array(
     'Authorization:key='.$server_key, 
     'Content-Type:application/json'
           );
              // here use $tokens as the replace $key
$fields= array('to'=>$token,
'notification'=>array('title'=>$title,'body'=>$message,
  'click_action'=>'com.jrcomjk.firebasemysql_TARGET_NOTIFICATION'
));
   $payload= json_encode($fields);
   $curl_session= curl_init();
   curl_setopt($curl_session,CURLOPT_URL,$path_to_fcm);
   curl_setopt($curl_session,CURLOPT_POST,true);
   curl_setopt($curl_session,CURLOPT_HTTPHEADER, $headers);
   curl_setopt($curl_session,CURLOPT_RETURNTRANSFER,true);
   curl_setopt($curl_session,CURLOPT_SSL_VERIFYPEER,false);
   curl_setopt($curl_session,CURLOPT_IPRESOLVE,CURL_IPRESOLVE_V4);
   curl_setopt($curl_session,CURLOPT_POSTFIELDS,$payload);
       $result =curl_exec($curl_session);     
       curl_close($curl_session); 
   mysqli_close($conn);
?>

Answer 1

我看到您声明： $tokens = array(); with s's"，但您在这里使用$令牌，没有" s"：

   $fields= array('to'=>$token'notification'=>array('title'=>$title,'body'=>$message,'click_action'=>'com.jrcomjk.firebasemysql_TARGET_NOTIFICATION'));

您的代码应该起作用，只需在此处配置firebase项目，该项目在firebase控制台上正确正确并相应地放置了服务器密钥。
