问题描述 投票：0回答：1

我正在为我的公司制作应用程序，我需要它在专用网络（VPN）上工作但是当我在VPN上它不起作用，试图打印结果女巫应该给我一个json而不是给我这个“

401 - 未授权：由于凭据无效，访问被拒绝。

“，但是如果我将URL更改为”[https://randomuser.me/api/?results=15][1]“我没有问题就得到了数据。当我在VPN上时，我试图检查连接，并给出结果无。

...
class _MyHomePageState extends State<MyHomePage> {

  var _connection = 'Unknown';
  Connectivity connectivity;
  StreamSubscription<ConnectivityResult> subscription;

  String url = 'myUrl';
  List data;

  Future<String> makeRequest() async {
    var response = await http
        .post(url, headers: {'Accept': 'application/json'});

  print('________________________________________________________________________^^^^ '+ response.body );
    setState(() {
      var extractdata = json.decode(response.body);
      //data = extractdata;
      //print( data[0]["name"]["first"]);
    });

  }

  @override
  void initState() {
    super.initState();
    connectivity = new Connectivity();
    subscription = connectivity.onConnectivityChanged.listen( (ConnectivityResult result){print('RESULT');print(result);});
    this.makeRequest();
  }

  @override
  void dispose(){
    subscription.cancel();
    super.dispose();
  }
