Question

在Asp.Net Core中，我重写了IdentityUser表以添加更多功能

public class Person : IdentityUser
    {
        public string Location {get; set; }
        public SellerType SellerType{get; set; }

    }
    public enum SellerType 
    {
        PrivateSeller , 
        Dealer
    }

我还有一个ViewModel类CredentialModel，我使用AutoMapper链接Person类

public class CredentialModel
  {
    public string UserName { get; set; }
    public string Password { get; set; }
    public string FirstName {get;set;}
    public string LastName {get; set; }
    public string Location {get; set; }
    public string SellerType{get; set; }
    public string[] SellerTypes {get; set; }
    public string PhoneNumber {get; set; }
  }

AutoMapper Profile Class

public class UserMapProfile : Profile
    {
        public UserMapProfile(){
          CreateMap<CarAdderUser, CredentialModel>()
             .ForMember(model=> model.SellerType , 
             opt=> opt.MapFrom(vm=>((SellerType)vm.SellerType).ToString()))
             .ForMember(model=> model.SellerTypes, opt=> opt.UseValue(Enum.GetNames(typeof(SellerType)).ToArray()))
                .ReverseMap();
        }
    }

我的问题在于控制器

像这样它可以工作，但我返回实体而不是VM

    [HttpGet("getUser/{username}")]
     public  IActionResult GetUser(string username)
     {
         var user= _userManager.FindByNameAsync(username);
         return Ok(user);
     }

就像这样，它会在邮递员中抛出404;

[HttpGet("getUser/{username}")]
     public  IActionResult GetUser(string username)
     {
         var user= _userManager.FindByNameAsync(username);
         return Ok(_mapper.Map<CredentialModel>(user));
     }

IT给我一个错误

 An unhandled exception has occurred: Missing type map configuration or unsupported mapping.

      Mapping types:
      Task`1 -> CredentialModel

不知道该怎么办......不是AutoMapper专家

Answer 1

解决了...问题是我忘记了我只需要结果...... 所以user.Result而不是用户在返回... 不确定其他内容是什么......它们不是DB中User表中的列

Answer 2

你不应该使用user.Result。这将阻止调用线程。请改用async/await。

 public async Task<IActionResult> GetUser(string username)
 {
     var user= await _userManager.FindByNameAsync(username);
     return Ok(_mapper.Map<CredentialModel>(user));
 }

从AutoMapper中的Asp.Net Identity映射User表
