Firebase 云消息消息 ID 显示但未收到通知

Question

我能够获得消息 ID 作为回报，但通知未显示在 android 设备中，但从 firebase 控制台运行良好，我可以从 firebase 控制台发送到主题“nadakko”

     <?php
 $data = array(
           "message" => "sfsdgdgdfg"
          );
  $final = array(
            "condition" => "'nadakko' in topics",
            "data" => $data
           );

  $url = 'https://fcm.googleapis.com/fcm/send';

  $headers = array(
              'Authorization: key=AIzaSyAkjY4wwambC7ryNxr-KEjsx4VgSZuh-UY',
              'Content-Type: application/json'
             );
  // Open connection
  $ch = curl_init();

  // Set the url, number of POST vars, POST data
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_POST, true);
  curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
  // Disabling SSL Certificate support temporarly
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
  curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($final));
  // Execute post
  $result = curl_exec($ch);

  if ($result === FALSE) {
      // curl failed
      echo "Faild";
  }
echo $result;
  // Close connection
  curl_close($ch);
  ?>

发送消息后，我从 android 监视器收到此错误消息已接收到移动设备，但存在一些问题

Answer 1

06-07 18:06:16.139 8802-12118/info.**.*** E/MyFirebaseMessagingService: Json Exception: No value for data

这是问题所在，您需要阅读message 而不是data 使用所以它将是

String message = json.getString("message");

Answer 2

JSONObject data = json.getJSONObject("data");
String title = data.getString("title");
String message = data.getString("message");
