我收到这个错误

Unhandled Exception: SocketException: OS Error: No route to host,
errno = 113, address = (my url api), port = 42392

尝试使用以下代码访问它时：

final String basicAuth = 'Basic ' + base64Encode(utf8.encode('$authUsername:$authPassword'));
final String _grantType = "password";

http.Response response = await http.post(
  Uri.encodeFull("this is my url api"),
  headers: <String, String>{
    "authorization": basicAuth,
    'content-type': 'application/x-www-form-urlencoded',
  },
  body: {
    "username": username,
    "password": password,
    "grant_type": _grantType,
  },
);

我已经使用邮递员尝试了该 URL，并且工作正常，我写得正确吗？我不确定是否放置授权基本授权码
