Android Firebase 两个节点 updateChildren，失败 : DatabaseError: Invalid token in path

Question

我正在尝试在 Firebase 中创建一个新数据并根据用户对其进行更新，但在尝试建立关系时我总是遇到错误。我附上了节点的图像和一些代码。

和代码:

        // Create a reference that point to transportador and the currenUser
    DatabaseReference wayPointRef;
    // Create a reference to the vehicle node db
    final DatabaseReference refVehicle = mDatabase.getReference("vehiculo");
    // Create a reference to the transportador node db
    final DatabaseReference refTrans = mDatabase.getReference("transportador");
    // Take the key create of the new vehicle
    final String key = refVehicle.push().getKey();
    // Show the key
    KLog.a("key of the new vehicle : " + key);

    mainHandler.post(new Runnable() {
        @Override
        public void run() {
            sweetAlertDialog = new SweetAlertDialog(actvty, SweetAlertDialog.PROGRESS_TYPE);
            sweetAlertDialog.getProgressHelper()
                    .setBarColor(Color.parseColor("#00C800"));
            sweetAlertDialog.setTitleText("xxxxxxx");
            sweetAlertDialog.setContentText("Creando Vehiculo");
            sweetAlertDialog.setCancelable(false);
            sweetAlertDialog.show();
        }
    });
    wayPointRef = refTrans.child(currentUserKey).child("vehiculos");
    vehicle = new Vehiculo(key, vehiculo, carroceria, placa, modelo, pesoMax, volumen, largo,
            alto, ancho);
    Map<String, Object> vehicleValues = vehicle.toMap();

    Map<String, Object> childUpdates = new HashMap<>();
    childUpdates.put(refVehicle + "/" + key, vehicleValues);
    childUpdates.put("/" + "vehiculos/" + key, vehicleValues);
    //mDatabase.updateChildren(childUpdates);

    final String finalCurrentUserKey = currentUserKey;
    wayPointRef.updateChildren(childUpdates, new DatabaseReference.CompletionListener() {
        @Override
        public void onComplete(final DatabaseError databaseError, DatabaseReference databaseReference) {
            if (databaseError != null){

这是日志答案:

Answer 1

最有可能发生的情况是您的 key 包含一些 Firebase 不允许您在节点 key 中包含的字符。

即:

• >。 (期间)
• $(美元符号)
• [(左方括号)
• ](右方括号)
• #(井号或井号)
• /(正斜杠)

一个简单的 String.replace() 应该可以在这里工作。
