Question

我有这个API项目来了解员工的详细信息。如何在Home控制器中获取类似于“ http://localhost:53037/api/employee/4”的API URL，并将该URL保存到数据库中？

员工控制者：

public class EmployeeController : ApiController
{
    public IEnumerable<Employee> Get()
    {
        using(EmployeeDBEntities entities = new EmployeeDBEntities())
        {
            return entities.Employees.ToList();
        }
    }

    public Employee Get(int id)
    {
        using (EmployeeDBEntities entities = new EmployeeDBEntities())
        {
            return entities.Employees.FirstOrDefault(e => e.ID == id);
        }
    }
    public void Post([FromBody] Employee employee)
    {
        using (EmployeeDBEntities entities = new EmployeeDBEntities())
        {
            entities.Employees.Add(employee);
            entities.SaveChanges();
        }
    }
}

家庭控制器：

    public class HomeController : Controller
{

    private readonly MyDBEntities _db = new MyDBEntities();

    public ActionResult Index()
    {
        return View();
    }
    public ActionResult About()
    {
        ViewBag.Message = "Your application description page.";

        return View();
    }

    public ActionResult Contact()
    {
        ViewBag.Message = "Your contact page.";

        return View();
    }

}

我认为关键是使用适当的属性

    [HttpGet]
    [Route("/api/employee/{id}/")]
    public Employee Get([FromRoute]int id)
    {
        using (EmployeeDBEntities entities = new EmployeeDBEntities())
        {
            return entities.Employees.FirstOrDefault(e => e.ID == id);
        }
    }

编辑：不确定我是否正确理解了这个问题，但是如果您尝试通过id从数据库中获取一名员工，这就是方法。与员工有关的所有事情都应通过EmployeeController进行。
