Question

我正在构建一个WebAPI，我已经用5个不同的组织填充了我的数据库，每个组织有3个不同的联系人，每个联系人有3个电话号码和EntityFramework。但不知何故，它表现得很奇怪：

我获得了联系人和组织的完整列表
我只是在组织下的联系人（GET - ＆gt; api / organizations）
我只通过联系人获得一部电话（GET - ＆gt; api / contacts）
它不接受api路由中的参数，例如：api / contacts / {id}或api / organizations {id}。它返回404代码。

我的问题：

1-模型之间的关系是否构建错误，因此我只得到一个子元素而不是整个列表？

2-为什么我的路线不接受参数{id}？

这些是我的模特：

**Organization:**
public class Organization    {
        public Guid Id { get; set; }
        public DateTime dateCreated { get; set; }
        public string organizationName { get; set; }
        public virtual ICollection<Contact> Contacts { get; set; }
    }

**Contact:**
public class Contact    {
        public Contact() { }
        public Guid Id { get; set; }
        public string firstName { get; set; }
        public string lastName { get; set; }
        public virtual ICollection<Phone> Phones { get; set; }

        // Foreign Key for Organizations
        public Guid OrganizationId { get; set; }

        //Related Organization entity
        [ForeignKey("OrganizationId")]
        public Organization OrganizationData { get; set; }
    }

**Phones:**
public class Phone    {
        public Guid Id { get; set; }
        public string customName { get; set; }
        public string phoneNumber { get; set; }

        // Foreign Key for Contacts
        public Guid ContactId { get; set; }

        //Related Contact entity
        [ForeignKey("ContactId")]
        public Contact ContactData { get; set; }
    }

这些是我的控制者：

**OrganizationsController:**
    [Route("api/organizations")]
    public class OrganizationsController : Controller
    {
            [HttpGet ("")]
        public IActionResult Get()
        {
                var results = _repository.GetAllOrganizations();
                return Ok(Mapper.Map<IEnumerable<Organization>>(results));   
        }

 [HttpGet("")]
        public IActionResult Get(Guid Id)
        {
                var organization = _repository.GetOrganizationById(Id);
                return Ok(organization);
        }
    }

**ContactsController**
[Route("api/organization/{id}/contacts")]
    public class ContactsController : Controller
    {

        [HttpGet("")]
        public IActionResult Get(Guid Id)
        {
                var organization = _repository.GetOrganizationById(Id);
                return Ok(organization.Contacts.ToList());
        }
        }
    }

**AllContactsController**
[Route("api/contacts")]
        public class AllController : Controller
        {
        [HttpGet("")]
        public IActionResult Get()
        {
                var results = _repository.GetAllContacts();
                return Ok(Mapper.Map<IEnumerable<Contact>>(results));
        }

        [HttpGet("/{id}")]
        public IActionResult Get(Guid Id)
        {
                var contact = _repository.GetContactById(Id);
                return Ok(contact);
        }

编辑：添加存储库：

  public class ContactManagementRepository : IContactManagementRepository
    {
        private ContactManagementContext _context;
        private ILogger<ContactManagementRepository> _logger;

        public ContactManagementRepository(ContactManagementContext context, ILogger<ContactManagementRepository> logger)
        {
            _context = context;
            _logger = logger;
        }

        public IEnumerable<Organization> GetAllOrganizations()
        {
            _logger.LogInformation("Getting All Organizations from the Database");
            return _context.Organizations.ToList();
        }

        public IEnumerable<Contact> GetAllContacts()
        {
            _logger.LogInformation("Getting All Contacts from the Database");
            return _context.Contacts.ToList();
        }

        public void AddOrganization(Organization organization)
        {
            _context.Add(organization);
        }

        public void AddContact(Guid id, Contact newContact)
        {
            var organization = GetOrganizationById(id);
            if(organization != null)
            {
                organization.Contacts.Add(newContact);
                _context.Contacts.Add(newContact);
            }
        }

        public async Task<bool> SaveChangesAsync()
        {
            return (await _context.SaveChangesAsync()) > 0;
        }

        public Organization GetOrganizationById(Guid Id)
        {
            return _context.Organizations
                .Include(c => c.Contacts)
                .Where(c => c.Id == Id)
                .FirstOrDefault();
        }

        public Contact GetContactById(Guid Id)
        {
            return _context.Contacts
                .Include(c => c.Addresses)
                .Include(c => c.Bankdatas)
                .Include(c => c.Phones)
                .Where(c => c.Id == Id)
                .FirstOrDefault();
        }

        public void DeleteContact(Guid id)
        {
            var contact = GetContactById(id);
            if (contact != null)
            {
                _context.Contacts.Remove(contact);
            }
        }
    }

Answer 1

尝试使用OrganizationsController

[HttpGet("{id}")]
public IActionResult Get(Guid Id)
{
        var organization = _repository.GetOrganizationById(Id);
        return Ok(organization);
}

并尝试AllController

[HttpGet("{id}")]
public IActionResult Get(Guid Id)
{
        var contact = _repository.GetContactById(Id);
        return Ok(contact);
}

你的模特对我来说很好看。你能展示一下你的存储库吗？

EntityFramework关系提供不正确的结果 - WebAPI不接受{id}
