Asp.net URL路由ASP核心MVC

我有两个模型。组织和网站。一个组织可以有多个站点，但一个站点只能有一个组织。我已经能够成功地创建一个页面，您可以创建一个组织及其主站点，所有保存到数据库的罚款

我想做的是有一个页面，显示一个组织的所有网站。我希望url类似于~/Organizations/6/Sites。要查看特定站点上的信息，url应为~/organizations/6/sites/2

我将如何实现这一目标？谁能给我指一下正确的方向吗。我的理解是，这将在startup.cs文件下的endpoints.mapcontrolleroute部分中完成

下面是组织的两个模型和查看操作，以及当前都位于orgcontroller中的站点的查看站点操作

以下是一个工作演示：

型号：

public class BaseEntity
{
    public Guid Id { get; set; }
}
public class Organization : BaseEntity
{
    [Required]
    [Display(Name = "Name")]
    public string Name { get; set; }

    [Display(Name = "Logo")]
    public string Logo { get; set; }

    [DataType(DataType.DateTime)]
    public DateTime CreatedDate { get; set; }

    [DataType(DataType.DateTime)]
    public DateTime ModifiedDate { get; set; }

    public int Demo { get; set; }

    [Required]
    public bool Active { get; set; }
    public virtual ICollection<Site> Sites { get; set; }
}

public class Site : BaseEntity
{

    [Required]
    [Display(Name = "Name")]
    public string Name { get; set; }

    [Display(Name = "Address")]
    public string FullAddress
    {
        get
        {
            return StreetNumber + " " + StreetAddress + " " + Suburb + " " + State + " " + PostCode + " " + Country;
        }
    }

    [Required]
    [Display(Name = "Street Number")]
    public string StreetNumber { get; set; }

    [Required]
    [Display(Name = "Street Address")]
    public string StreetAddress { get; set; }

    [Required]
    [DataType(DataType.PostalCode)]
    [Display(Name = "Postcode")]
    public string PostCode { get; set; }

    [Required]
    [Display(Name = "Suburb")]
    public string Suburb { get; set; }

    [Required]
    [Display(Name = "State")]
    public string State { get; set; }

    [Required]
    [Display(Name = "Country")]
    public string Country { get; set; }

    [Required]
    [DataType(DataType.PhoneNumber)]
    [Display(Name = "Phone Number")]
    public string PhoneNumber { get; set; }

    [DataType(DataType.DateTime)]
    public DateTime CreatedDate { get; set; }

    [DataType(DataType.DateTime)]
    public DateTime ModifiedDate { get; set; }

    [Required]
    public bool IsPrimary { get; set; }
    public int Demo { get; set; }

    [Required]
    public bool Active { get; set; }

    [Display(Name = "Image")]
    public string Image { get; set; }

    public virtual Organization Organization { get; set; }
}

结果:

请求url:

更新：

app.UseEndpoints(endpoints =>
{
    endpoints.MapControllerRoute(
        name: "default",
        pattern: "{controller=Home}/{action=Index}/{id?}");
    endpoints.MapControllerRoute(
        name: "custom",
        pattern: "Organizations/{id?}/{sites}/{siteId?}",
        defaults: new { controller = "Organizations", action = "Details" });
});

或者，一种简单的方法是使用路由属性：

[Route("[controller]/{id}/sites/{siteId}")]
public async Task<IActionResult> Details(Guid id,Guid? siteId )

[Route（“[controller]/{id}/sites/{siteId}”）]
公共异步任务详细信息（Guid id、Guid？站点id）

我最终的做法是

控制器

        // GET: Organizations/5
        // GET: Organizations
        [Route("[controller]/{id?}")]
        public async Task<IActionResult> View(int? id)
        {
            if (id == 0)
            {
                return NotFound();
            }
            if (id == null)
            {
                return View("ViewAll",await _context.Organizations.Include("Sites").Include("Contacts").ToListAsync());
            }
            var organization = _context.Organizations.Include("Sites").Include("Contacts").FirstOrDefault(x=> x.ID == id);
            if (organization == null)
            {
                return NotFound();
            }
            return View("View",organization);
        }

        // GET: Organizations/5/Sites/2
        // GET: Organizations/5/Sites
        // GET: Organizations/5
        [Route("[controller]/{id}/sites/{siteId?}")]
        public async Task<IActionResult> ViewSites(int ordId, int? siteId)
        {
            if (ordId == 0)
            {
                return NotFound();
            }
            if (siteId == 0)
            {
                List<Site> sites = _context.Organizations.Include("Sites").Where(x => x.ID == ordId).ToList().FirstOrDefault().Sites.ToList();
                return View("ViewSites",sites);
            }
            Site site = _context.Organizations.Include("Sites").Where(x => x.ID == ordId).ToList().FirstOrDefault().Sites.ToList().Where(y=>y.ID == siteId).FirstOrDefault();
            return View("ViewSite", site);


        }

为了这个打安斯克。请检查我的答案。如果我的答案对您有帮助，您可以吗？谢谢。

public async Task Details（Guid？Id，Guid siteId）

应该是

（Guid Id，Guid？siteId）

如果（siteId==0）

应该是

如果（siteId.HasValue）&&siteId==0

如果sideid为空，您的代码将抛出。虽然IMHO，

if（siteId.HasValue）&&siteId==default（int））

更准确地表达了您的意图。检索单个站点应简化为

site-site=\u context.Sites.Where（s=>s.ID==siteId.FirstOrDefault（）
[Route("[controller]/{id}/sites/{siteId}")]
public async Task<IActionResult> Details(Guid id,Guid? siteId )

        // GET: Organizations/5
        // GET: Organizations
        [Route("[controller]/{id?}")]
        public async Task<IActionResult> View(int? id)
        {
            if (id == 0)
            {

            }
            return View("View",organization);
        }
