PHP 世博会推送通知

我正在尝试使用 PHP 向我的 React Native 应用程序发送推送通知， 下面的代码也发送了所有注册其令牌的用户，并且它一次发送了大量通知，尽管该令牌适用于特定设备，但它不断将通知推送给所有用户

$key = "ExponentPushToken[0GAEokJazChx21MOxeC1l2]";
$title = "title";
$interestDetails = ['https://exp.host/--/api/v2/push/send',$key];

  try{

      $expo = \ExponentPhpSDK\Expo::normalSetup();

  // Subscribe the recipient to the server
      $expo->subscribe($interestDetails[0], $interestDetails[1]);

  // Build the notification data

    $notification = ['title' => $title,'body' => $msg];

  // Notify an interest with a notification
   $expo->notify($notification);

  $status = 'success';
}catch(Exception $e){



}


   ?>

我尝试更改我的代码如下

<?php

$key = "ExponentPushToken[0GAEokJazChx21MOxeC1l2]";
$title = "title";


  try{

      $expo = \ExponentPhpSDK\Expo::normalSetup();



  // Build the notification data

  $notification = ['to' => $key,'title' => $title,'body' => $msg];

  // Notify an interest with a notification
 $expo->notify('https://exp.host/--/api/v2/push/send',$notification);

  $status = 'success';
}catch(Exception $e){
    echo $e;
}




  echo $status;


  ?>

它确实发送给特定用户，但仍然一次发送大量通知？

如果没有expo php sdk，也可以这样完成。

  <?php

    $payload = array(
        'to' => 'ExponentPushToken[xxborxxxxxxxxxx]',
        'sound' => 'default',
        'body' => 'hello',
    );

$curl = curl_init();

curl_setopt_array($curl, array(
  CURLOPT_URL => "https://exp.host/--/api/v2/push/send",
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_ENCODING => "",
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 30,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => "POST",
  CURLOPT_POSTFIELDS => json_encode($payload),
  CURLOPT_HTTPHEADER => array(
    "Accept: application/json",
    "Accept-Encoding: gzip, deflate",
    "Content-Type: application/json",
    "cache-control: no-cache",
    "host: exp.host"
  ),
));

$response = curl_exec($curl);
$err = curl_error($curl);

curl_close($curl);

if ($err) {
  echo "cURL Error #:" . $err;
} else {
  echo $response;
}
?>
