获取用户模型数组列表

Question

我需要在GetUserModel中获得支付数组，它从nodeJs api返回数据库信息

我明白了:

List? payments
Future getCurrentUser() async {
var loginDetails = await SharedService.loginDetails();
email = loginDetails?.data.email;
GetUserRequestModel model = GetUserRequestModel(email: email!);

var currentUserInfo = await APIService.getUserInfo(model);
balance = currentUserInfo.data?.balance;
payments = currentUserInfo.data?.payments; //does not working
print(payments)
}

currentUserInfo给我的一切，但我不能得到支付数组。print(支付)给我"即时付款";我怎样才能得到支付数组正确?

userresponsemmodel:

import 'dart:convert';
GetUserResponseModel getUserResponseModelJSON(String str) =>
GetUserResponseModel.fromJson(json.decode(str));
class GetUserResponseModel {
GetUserResponseModel({
required this.message,
required this.data,
});
late final String message;
late final Data? data;
GetUserResponseModel.fromJson(Map<String, dynamic> json) {
message = json['message'];
data = (json['data'] != null ? Data.fromJson(json['data']) : null);
}
Map<String, dynamic> toJson() {
final _data = <String, dynamic>{};
_data['message'] = message;
_data['data'] = data?.toJson();
return _data;
}
}
class Data {
Data({
required this.username,
required this.email,
required this.balance,
required this.date,
required this.payments,
required this.id,
});
late final String username;
late final String email;
late final int balance;
late final String date;
late final List<Payments> payments;
late final String id;
Data.fromJson(Map<String, dynamic> json) {
username = json['username'];
email = json['email'];
balance = json['balance'];
date = json['date'];
payments =
List.from(json['payments']).map((e) => Payments.fromJson(e)).toList();
id = json['id'];
}
Map<String, dynamic> toJson() {
final _data = <String, dynamic>{};
_data['username'] = username;
_data['email'] = email;
_data['balance'] = balance;
_data['date'] = date;
_data['payments'] = payments.map((e) => e.toJson()).toList();
_data['id'] = id;
return _data;
}
}
class Payments {
Payments({
required this.paymentCost,
required this.paymentDate,
required this.id,
});
late final int paymentCost;
late final String paymentDate;
late final String id;
Payments.fromJson(Map<String, dynamic> json) {
paymentCost = json['paymentCost'];
paymentDate = json['paymentDate'];
id = json['_id'];
}
Map<String, dynamic> toJson() {
final _data = <String, dynamic>{};
_data['paymentCost'] = paymentCost;
_data['paymentDate'] = paymentDate;
_data['_id'] = id;
return _data;
}
}

这是getUserInfo:

static Future<GetUserResponseModel> getUserInfo(
GetUserRequestModel model) async {
var loginDetails = await SharedService.loginDetails();
Map<String, String> requestHeaders = {
'Content-Type': 'application/json',
'Authorization': 'Basic ${loginDetails!.data.token}'
};
var url = Uri.http(Config.apiURL, Config.getUserInfoAPI);
var response = await client.post(
url,
headers: requestHeaders,
body: jsonEncode(model.toJson()),
);
return getUserResponseModelJSON(response.body);
}

所以我想你是想打印支付数据。

在payments类中，你应该添加

@override
String toString() {
return ""; 
// Return how you want to print the data. Here you could add for example the JSON output.  
}

那么这个类就是这样的

class Payments {
Payments({
required this.paymentCost,
required this.paymentDate,
required this.id,
});
late final int paymentCost;
late final String paymentDate;
late final String id;
Payments.fromJson(Map<String, dynamic> json) {
paymentCost = json['paymentCost'];
paymentDate = json['paymentDate'];
id = json['_id'];
}
Map<String, dynamic> toJson() {
final _data = <String, dynamic>{};
_data['paymentCost'] = paymentCost;
_data['paymentDate'] = paymentDate;
_data['_id'] = id;
return _data;
}
@override
String toString() {
return "${this.paymentCost!} : ${this.paymentDate!} : ${this.id!}";
}
}

我没有测试过这段代码。
