将令牌附加到传出的 Http 请求，但找不到页面 [关闭]

Question

我是 Flutter 的新手 当我向传出的 Http 请求添加令牌但找不到页面时。 你可以看到我在尝试 catch 块它显示错误并且我还打印 Http 状态码

它还打印 404 有什么解决办法

Future<void> fetchandSetProduct() async {
var url = Uri.https('cakejaffna-default-rtdb.firebaseio.com',
    '/cakelist.json?auth=$authToken');

try {
  final response = await http.get(url);
  print(" ");
  print(url);
  print(response.statusCode);

  final extractData = json.decode(response.body) as Map<String, dynamic>;
  if (extractData == null) {
    return;
  }
  final List<Cake> loadedProduct = [];
  print(extractData);
  extractData.forEach((cakeId, cakeData) {
    loadedProduct.add(Cake(
        id: cakeId,
        imageUrl: cakeData['imageUrl'],
        title: cakeData['title'],
        hotelName: cakeData['hotelName'],
        rating: cakeData['rating'],
        ratecount: cakeData['ratecount'],
        amount: cakeData['amount'],
        details: cakeData['details'],
        categories: cakeData['categories'] as List<dynamic>));
  });
  print("karan");
  print(loadedProduct[0].imageUrl);
  _cakeList = loadedProduct;
  notifyListeners();
} catch (error) {
  print(error);
  print("rellay error");
}

}

网址格式应该这样改变

final url = Uri.https('cakejaffna-default-rtdb.firebaseio.com',
    '/cakelist.json', {'auth': '$authToken'});
