{[ApiController][Route([controller])]public class HomeController : ControllerBase{private readonly ILoggerHomeController _logger;public HomeController(ILoggerHomeController logger){_logger logger;}[HttpGet]public Person GetPerson(){_logger.LogInformation(请求person);return new Person() { ID 100, Name 张三丰收, Age 22, Sex true };}}public class Person{public int ID { get; set; }public string Name { get; set; }public int Age { get; set; }public bool Sex { get; set; }}
}
