Question

我重新编辑了这个问题。

我有一个API方法应该返回一个客户，包括来自其他表的数据。当我使用Swagger测试API时，我获得了一些ID的值，但没有获得customerId == 1的值。

DAL客户模型类：

public class Customer : AuditableEntity
{
    public int Id { get; set; }
    public string Name { get; set; }
    // other props deleted for readability 

    public ICollection<Shipping> Shippings {get; set; }
    public ICollection<Billing> Billings {get; set; }
    public ICollection<Payer> Payers {get; set; }
    public ICollection<Logistic> Logistics {get; set; }

}

航运模型类

public class Shipping : AuditableEntity
{
    public int Id { get; set; }
    public string Name { get; set; }
    // other props deleted for readability

    public int CustomerId { get; set; }
    public Customer Customer { get; set; }

}

CustomerViewModel

 public class CustomerViewModel
{
    public int Id { get; set; }
    public string Name { get; set; }
    // other props deleted for readability

    public ICollection<ShippingViewModel> Shippings { get; set; }
    public ICollection<BillingViewModel> Billings { get; set; }
    public ICollection<PayerViewModel> Payers { get; set; }
    public ICollection<LogisticViewModel> Logistics { get; set; }
}

public class CustomerViewModelValidator : AbstractValidator<CustomerViewModel>
{
    public CustomerViewModelValidator()
    {
        RuleFor(register => register.Name).NotEmpty().WithMessage("Customer name cannot be empty");
    }
}

存储库：

public class CustomerRepository : Repository<Customer>, ICustomerRepository
{
    public CustomerRepository(ApplicationDbContext context) : base(context)
    { }

    public Customer GetCustomerById(int customerId)
    {
        return _appContext.Customers
            .Include(c => c.Shippings)
            .Include(c => c.Billings)
            .Include(c => c.Payers)
            .Include(c => c.Logistics)
            .Single(x => x.Id == customerId) 
            //.SingleOrDefault(x => x.Id == customerId)               
            ;
    }

API控制器

[Authorize(AuthenticationSchemes = IdentityServerAuthenticationDefaults.AuthenticationScheme)]
[Route("api/[controller]")]
public class CustomerController : Controller
{
    private readonly IAuthorizationService _authorizationService;
    private IUnitOfWork _unitOfWork;
    readonly ILogger _logger;
    readonly IEmailer _emailer;


    public CustomerController(IUnitOfWork unitOfWork, ILogger<CustomerController> logger, IEmailer emailer,
            IAuthorizationService authorizationService)
    {
        _unitOfWork = unitOfWork;
        _logger = logger;
        _emailer = emailer;
        _authorizationService = authorizationService;
    }

    // GET api/value/5
    [HttpGet("{id}")]
    public IActionResult GetCustomerById(int id)
    {
        var customer = _unitOfWork.Customers.GetCustomerById(id);
        return Ok(Mapper.Map<Customer>(customer));
    }

数据库的表客户值为1到6。表格发送包含1个链接到customerId == 1的值。

当我测试API时，我无法获取customerId == 1的值。它会产生响应代码0.标题==＆＃34;错误＆＃34;：＆＃34;服务器没有响应＆＃34; 。响应主体=＆＃34;没有内容＆＃34;。

当我用ID == 2,3，...测试时，我可以获得值ex：
响应代码== 200
  {
  ＆＃34; id＆＃34;：2，
  ＆＃34; name＆＃34;：＆＃34; Inion＆＃34;，
  //为了便于阅读而删除休息
  ＆＃34; shippings＆＃34;：[]，
  ＆＃34;账单＆＃34;：[]，
  ＆＃34;付款人＆＃34;：[]，
  ＆＃34;后勤＆＃34;：[]，
  ＆＃34; updatedDate＆＃34;：＆＃34; 2018-02-08T15：41：45.4929139＆＃34;，
  ＆＃34; createdDate＆＃34;：＆＃34; 2018-02-08T15：41：45.4929139＆＃34;
  }

Answer 1

感谢所有快速反应的人，如果我不清楚，请对不起。

检查完db后，我找不到错误。

@CodeCaster指向API控制器，忽略了我映射错误的类。

当然我有其他ID为空标签的返回值，因为其他ID没有在其他表中链接的值，只有id = 1。我已经对更改进行了测试，并在链接表中添加了更多数据，以确保所有数据都按预期工作。

正确的API控制器方法

    [HttpGet("{id}")]
    public IActionResult GetCustomerById(int id)
    {
        var customer = _unitOfWork.Customers.GetCustomerById(id);
        return Ok(Mapper.Map<CustomerViewModel>(customer));
    }

API未返回所有预期值
