Firebase Cloud Messaging消息ID显示但未接收通知

Question

我能够获得消息ID的回报，但是通知未显示在Android设备中，但是它可以从Firebase Console中运行正常，我可以从Firebase发送到主题" Nadakko"控制台

     <?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监视器中收到了此错误，该消息已接收到手机上的消息，但是有一些问题

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

Answer 1

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

这是问题，您需要读取message而不是data使用，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");
