mongodb - I/flutter (30720) : SocketException: OS Error: Connection timed out, errno = 110，地址 = 192.19.170.13，端口 = 47763

Question

我使用的是真实设备(不是安卓模拟器)
后端: MongoDb 图集 ,
API:带-beta ，得到这个错误:
I/flutter (30720): SocketException: OS Error: Connection timed out, errno = 110, address = 192.19.170.13, port = 47763
(发现了很多类似的问题，但没有一个是使用真实设备进行测试的)

    try {
      var ip = '192.19.170.13';
      setState(() => _isSubmitting = true);
      http.Response response =
          await http.post('http://$ip:1337/auth/local/register',
 /* I've also tried using localhost(it didn't work) everyone suggested to use my loopback adapter's (Ethernet's ip address) even that isn't working.*/
 body: {
        'username': _username,
        'email': _email,
        'password': _password,
      });

      final responseData = json.decode(response.body);
      setState(() => _isSubmitting = false);
      _successSnackBar();
      print(responseData);
    } catch (e) {
      setState(() => _isSubmitting = false);
      print(e.toString());
    }
  }

如果您使用的是 Chrome，则需要访问
Chrome ://检查/#devices
并像这样将您的端口添加到“端口转发”

并确保您的设备上有 USB 调试。
