我正在使用 dio ，我正在传递表单数据并获得响应，但无法将数据存储到对象。请帮我 当我打印response.data时，它给出了响应，但是我没有得到如何将响应存储到对象中。
class MainActivityGrid extends StatefulWidget {
@override
_MainActivityGridState createState() => _MainActivityGridState();
}
class _MainActivityGridState extends State<MainActivityGrid> {
// List<ImageModel>images= [];
@override
Widget build(BuildContext context) {
return MaterialApp(
home: new Scaffold(
appBar: AppBar(
title: new Text("IPTV"),
),
body: new Center(
child: new RaisedButton(
child: new Text("Button"), onPressed: fetchImage),
),
),
);
}
Future<String> fetchImage() async {
String url = "http://xxxxxx:xxx/onnet_api/mediaList.php";
Response response;
Dio dio = new Dio();
FormData formData = new FormData.from(
{"publisherid": 102, "tag": "media", "subtag": "list"});
// counter ++;
response = await dio.post(url, data: formData);
// dio.interceptors.add(LogInterceptor(responseBody: fa));
//int status = response.data["status"]["data"];
//Map responseBody = response.data;
//loginResponse = new LoginResponse.fromJson(json.decode(response.data));
print(response.data["data"][0]);
//ImageModel imageModel = new ImageModel.fromJson(json.decode(response.data[]));
//print('response media: $status');
/* setState(() {
//images.add(imageModel);
});*/
}
}
我对我的API的JSON响应如下所示：请尝试帮助我。

答案 0 :(得分：1)
无需为Dio使用Json Decode。您可以执行以下操作：
Response responseval=await dio.post(url,options: Options(headers: headers));
var name=responseval.data['username'];
var id=responseeval.data['id'];
答案 1 :(得分：0)
将Bean或Dio转换成这样的响应，或者您可以使用this将JSON响应转换为dart bean

此方法将响应您的响应bean对象
Future<Welcome> getMediaList() async {
String url='http://xxxxxx:xxx/onnet_api/mediaList.php';
http.Response res = await http.get(url);
final jsonData = json.decode(res.body);
var map=Map<String, dynamic>.from(jsonData);
var response=Welcome.fromJson(map);
if (res.statusCode == 200) {
return response;
} else {
throw Exception('Failed to load post');
}
}
像这样调用此方法
getMediaList().then((onValue){// on value is an object ot bean class //here you will be able to get members of your bean class })
另一种致电服务的方式是FutureBuilder<Welcome>();
您可以在http.post帖子网址中添加标题和正文。
Future<UserResponse> loginService() async {
String qaurl = "https://www.xxxxxxxxx.com/api/loginapi.html";
var body = new Map<String, String>(); //here i defined Map ty
body['email'] =_email; // pe
body['password'] = _password;
body['return'] = 'json';
body['apikey'] = ApiKey;
http.Response res = await http.post(qaurl, body: body);
final jsonData = json.decode(res.body);
var map=Map<String, dynamic>.from(jsonData);
var loginResponse=UserResponse.fromJsonMap(map);
if (res.statusCode == 200) {
return loginResponse;
} else {
Navigator.of(context, rootNavigator: true).pop('dialog');
throw Exception('Failed to load post');
}
}
