我在flutter项目中的http-get json数据无法获取数据，我用邮递员测试过，它成功了，但是在flutter中它没有或者因为我不知道如何输入。我已经尝试不同的方法，但没有一个成功！
谁能帮我？！如果有人需要更多信息，我会给你！

Future<Get> getdata(String id) async {
final username = 'test';
final password = '9876543';
final credentials = '$username:$password';
final stringToBase64 = utf8.fuse(base64);
final encodedCredentials = stringToBase64.encode(credentials);
final String apiUrl = "http://sv.com/api/values/";
Map<String, String> headers = {
HttpHeaders.contentTypeHeader: "application/json; charset=utf-8",
HttpHeaders.authorizationHeader: "Basic $encodedCredentials",
};
final response = await http.get(apiUrl,headers: headers);
if (response.statusCode == 200) {
final String responseString = response.body;
print(response.statusCode);
print(responseString);
return Get.fromJson(json.decode(response.body));
} else {
print(response.statusCode);
print(response.body);
}
}
上课
class Get {
final String id;
Get({
this.id,
});
factory Get.fromJson(Map<String, dynamic> json) {
return Get(
id: json['id_machdien'].toString()
);
}
}
主要的
class _MyHomePageState extends State<MyHomePage> {
Get _dataget;
@override
Widget build(BuildContext context) {
return MaterialApp(
home: Scaffold(
appBar: AppBar(
title: Text(widget.title),
),
body:Center(
child: Column(
children: <Widget> [
RaisedButton(
onPressed: () async{
final Get dataget = await getdata(id);
setState(() {
_dataget = dataget;
});
},
child: Text('Mở',style: TextStyle(fontSize: 15)),
),
],
),
),
)
);
}
}
