【问题描述】：

我是 abp.io 框架的新手，确切地说是 Angular + Entity Framework Core。

我希望能够创建或显示我已创建的类的对象列表。

例如，我在域层创建了一个名为 Address 的类。

这是它在应用层的AppService：

namespace ASKOM.RefPlusStudio.core.Services

[Authorize(corePermissions.Addresses.Default)]
public class AddressAppService : coreAppService, IAddressAppService

    private readonly IAddressRepository _addressRepository;
    private readonly AddressManager _addressManager;

    public AddressAppService(IAddressRepository addressRepository, AddressManager addressManager)
    
        _addressRepository = addressRepository;
        _addressManager = addressManager;
    

    [Authorize(corePermissions.Addresses.Create)]
    public async Task<AddressDto> CreateAsync(CreateUpdateAddressDto input)
    
        var address = await _addressManager.CreateAsync(
            input.StreetNumber,
            input.StreetName,
            input.PostalCode,
            input.City,
            input.Country
        );

        await _addressRepository.InsertAsync(address);

        return ObjectMapper.Map<Address, AddressDto>(address);
    

    [Authorize(corePermissions.Addresses.Delete)]
    public async Task DeleteAsync(Guid id)
    
        await _addressRepository.DeleteAsync(id);
    

    public async Task<AddressDto> GetAsync(Guid id)
    
        var address = await _addressRepository.GetAsync(id);
        return ObjectMapper.Map<Address, AddressDto>(address);
    

    public async Task<PagedResultDto<AddressDto>> GetListAsync(GetAddressListDto input)
    
        if (input.Sorting.IsNullOrWhiteSpace())
        
            input.Sorting = nameof(Address.Country);
        

        var addresses = await _addressRepository.GetListAsync(
            input.SkipCount,
            input.MaxResultCount,
            input.Sorting,
            input.Filter
        );

        var totalCount = await AsyncExecuter.CountAsync(
            _addressRepository.WhereIf(
                !input.Filter.IsNullOrWhiteSpace(),
                address => address.Country.Contains(input.Filter)
            )
        );

        return new PagedResultDto<AddressDto>(
            totalCount,
            ObjectMapper.Map<List<Address>, List<AddressDto>>(addresses)
        );
    

    [Authorize(corePermissions.Addresses.Edit)]
    public async Task UpdateAsync(Guid id, CreateUpdateAddressDto input)
    
        var address = await _addressRepository.GetAsync(id);
           
            address.StreetNumber = input.StreetNumber;
            address.StreetName = input.StreetName;
            address.PostalCode = input.PostalCode;
            address.City = input.City;
            address.Country = input.Country;

        await _addressRepository.UpdateAsync(address);
    
 
  

我给了他们所有需要的权限。

这里是 corePermissions.cs ：

namespace ASKOM.RefPlusStudio.core.Permissions

public static class corePermissions

    public const string GroupName = "core";

    //Add your own permission names. Example:
    //public const string MyPermission1 = GroupName + ".MyPermission1";

    public static class Addresses
    
        public const string Default = GroupName + ".Addresses";
        public const string Create = Default + ".Create";
        public const string Edit = Default + ".Edit";
        public const string Delete = Default + ".Delete";
    

我想看看它是否可以显示地址列表，所以我在 DataSeeder 上制作了一个静态列表：

namespace ASKOM.RefPlusStudio.core

public class coreDataSeederContributor : IDataSeedContributor, ITransientDependency

    private readonly IRepository<Address, Guid> _addressRepository;
    private readonly IGuidGenerator _guidGenerator;

    public coreDataSeederContributor(IRepository<Address, Guid> addressRepository, IGuidGenerator guidGenerator)
    
        _addressRepository = addressRepository;
        _guidGenerator = guidGenerator;
    

    public async Task SeedAsync(DataSeedContext context)
    
        if (await _addressRepository.GetCountAsync() > 0)
        
            return;
        
        var address = new Address(

                id: _guidGenerator.Create(),
                streetNumber: 07,
                streetName: "Med Salah Belhaj",
                postalCode: 2080,
                city: "Ariana",
                country: "Tunisie"
            );
            //autoSave: true
        
        await _addressRepository.InsertAsync(address);
    

现在是 Swagger UI 上的结果：

当我尝试打开请求 URL 时，显示如下：

我确定我可能忘记了一些东西，这就是为什么我在请求 URL 上被拒绝访问，但我真的不知道它是什么，因为我是这方面的新手。

你能帮帮我吗？ 谢谢

【参考方案1】：

数据库有问题。这就是它没有读取我在 DataSeedProvider 中提供的数据的原因。
