使用Dart语言解析嵌套的JSON数组并将其放在Model类中

关于我在这里的问题

我想解析JSON数组中没有键的JSON数组,并将其放在Model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

},

]

我已经成功解析了主数组,但是无法解析images包含整数数组的键。我想将其放入Model类。请帮忙。

谢谢!

回答:

您可以这样操作:

    final jsonList = json.decode(response.body) as List;

final userList = jsonList.map((map) => User.fromJson(map)).toList();

用户类别

        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());

}

}

    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]}");

}

}
