Dio 没有响应关闭 API

Question

我使用 API 来处理登录和存储令牌。 如果凭据有效，响应将获得一个令牌，如果凭据无效，则返回一个错误。 现在它工作正常，我得到了令牌，如果有错误，catch 方法会显示它，但是当我关闭 API 并发出 POST 请求时，我根本没有得到任何响应。 如何处理与 DIO 的连接错误？

Future<bool> login(String email, String password) async {
  try {
    var data = {
      'email': email,
      'password': password,
      'device_name': 'mobile'
    };
    Response response = await _dio.post(
      url + 'sanctum/token',
      data: data,
      options: Options(
        headers: {
          'Accept': 'application/json',
        },
      ),
    );
    await _storage.write(key: 'token', value: response.toString());
    return true;
  } catch (e) {
    print(e.response.toString());
    return false;
  }
}

尝试使用finally而不是catch返回false ：

Future<bool> login(String email, String password) async {
  try {
    // Make the request here like you already are
    return true;
  } catch (e) {
    print(e.response.toString());
  } finally {
    // This wouldn't get called if you already returned from the try block before, 
    // but would get called after catch if an exception was caught.
    return false; 
  }
}
