关于我的问题here
我想解析一个在 JSON 数组中没有键的 JSON 数组,并将其放入模型类中。
这是我要解析的 JSON 数组。
[
{
"pk": 100,
"user": 5,
"name": "Flutter",
"details": "Fluttery",
"images": [
89,
88,
87,
86
],
"priority": 5
},
{
"pk": 99,
"user": 5,
"name": "",
"details": "h",
"images": [],
"priority": 5
},
{
"pk": 98,
"user": 5,
"name": "Flutter",
"details": "Fluttery",
"images": [
85
],
"priority": 5
},
]
我已成功解析主数组,但无法解析包含整数数组的 images
键。我想把它放到模型类中。请帮忙。
谢谢!
最佳答案
你可以这样做:
final jsonList = json.decode(response.body) as List;
final userList = jsonList.map((map) => User.fromJson(map)).toList();
用户类
class User {
final int pk;
final String name;
final List<int> images;
User._({this.pk, this.name, this.images});
factory User.fromJson(Map<String, dynamic> json) {
return new User._(
pk: json['pk'],
name: json['name'],
images: (json['images'] as List).map((map) => int.parse("$map")).toList());
}
}
打印您的数据
for (var i = 0; i < userList.length; i++) {
print(userList[i].name);
final imageList = userList[i].images;
for (var j = 0 ; j < imageList.length; j++){
print("image: ${imageList[j]}");
}
}
关于arrays - 使用 Dart 语言解析嵌套的 JSON 数组并将其放入模型类中,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/51978610/
