本篇继续完成分类、标签、友情链接的后台操作接口，还是那句话，这些纯CRUD的内容，建议还是自己动手完成比较好，本篇将不再啰嗦，直接贴代码，以供参考。
分类
添加接口：查询分类列表QueryCategoriesForAdminAsync()、新增分类InsertCategoryAsync(...)、更新分类UpdateCategoryAsync(...)、删除分类DeleteCategoryAsync(...)
#region Categories/// <summary>
/// 查询分类列表
/// </summary>
/// <returns></returns>
Task<ServiceResult<IEnumerable<QueryCategoryForAdminDto>>> QueryCategoriesForAdminAsync();/// <summary>
/// 新增分类
/// </summary>
/// <param name="input"></param>
/// <returns></returns>
Task<ServiceResult> InsertCategoryAsync(EditCategoryInput input);/// <summary>
/// 更新分类
/// </summary>
/// <param name="id"></param>
/// <param name="input"></param>
/// <returns></returns>
Task<ServiceResult> UpdateCategoryAsync(int id, EditCategoryInput input);/// <summary>
/// 删除分类
/// </summary>
/// <param name="id"></param>
/// <returns></returns>
Task<ServiceResult> DeleteCategoryAsync(int id);#endregion Categories
查询分类列表需要返回的模型类QueryCategoryForAdminDto.cs。
//QueryCategoryForAdminDto.cs
namespace Meowv.Blog.Application.Contracts.Blog
{public class QueryCategoryForAdminDto : QueryCategoryDto{/// <summary>/// 主键/// </summary>public int Id { get; set; }}
}
新增分类和更新分类需要的输入参数EditCategoryInput.cs，直接继承CategoryDto即可。
//EditCategoryInput.cs
namespace Meowv.Blog.Application.Contracts.Blog.Params
{public class EditCategoryInput : CategoryDto{}
}
分别实现这几个接口。
/// <summary>
/// 查询分类列表
/// </summary>
/// <returns></returns>
public async Task<ServiceResult<IEnumerable<QueryCategoryForAdminDto>>> QueryCategoriesForAdminAsync()
{var result = new ServiceResult<IEnumerable<QueryCategoryForAdminDto>>();var posts = await _postRepository.GetListAsync();var categories = _categoryRepository.GetListAsync().Result.Select(x => new QueryCategoryForAdminDto{Id = x.Id,CategoryName = x.CategoryName,DisplayName = x.DisplayName,Count = posts.Count(p => p.CategoryId == x.Id)});result.IsSuccess(categories);return result;
}
/// <summary>
/// 新增分类
/// </summary>
/// <param name="input"></param>
/// <returns></returns>
public async Task<ServiceResult> InsertCategoryAsync(EditCategoryInput input)
{var result = new ServiceResult();var category = ObjectMapper.Map<EditCategoryInput, Category>(input);await _categoryRepository.InsertAsync(category);result.IsSuccess(ResponseText.INSERT_SUCCESS);return result;
}
这里需要一条AutoMapper配置，将EditCategoryInput转换为Category，忽略Id字段。
CreateMap<EditCategoryInput, Category>().ForMember(x => x.Id, opt => opt.Ignore());
/// <summary>
/// 更新分类
/// </summary>
/// <param name="id"></param>
/// <param name="input"></param>
/// <returns></returns>
public async Task<ServiceResult> UpdateCategoryAsync(int id, EditCategoryInput input)
{var result = new ServiceResult();var category = await _categoryRepository.GetAsync(id);category.CategoryName = input.CategoryName;category.DisplayName = input.DisplayName;await _categoryRepository.UpdateAsync(category);result.IsSuccess(ResponseText.UPDATE_SUCCESS);return result;
}
/// <summary>
/// 删除分类
/// </summary>
/// <param name="id"></param>
/// <returns></returns>
public async Task<ServiceResult> DeleteCategoryAsync(int id)
{var result = new ServiceResult();var category = await _categoryRepository.FindAsync(id);if (null == category){result.IsFailed(ResponseText.WHAT_NOT_EXIST.FormatWith("Id", id));return result;}await _categoryRepository.DeleteAsync(id);result.IsSuccess(ResponseText.DELETE_SUCCESS);return result;
}
在BlogController.Admin.cs中添加接口。

截止本篇，基于 abp vNext 和 .NET Core 开发博客项目 系列的后台API部分便全部开发完成了。
本博客项目系列是我一边写代码一边记录后的成果，并不是开发完成后再拿出来写的，涉及到东西也不是很多，对于新手入门来说应该是够了的，如果你从中有所收获请多多转发分享。
在此，希望大家可以关注一下我的微信公众号：『阿星Plus』，文章将会首发在公众号中。
现在有了API，大家可以选择自己熟悉的方式去开发前端界面，比如目前我博客的线上版本就是用的 ASP.NET Core Web ，感兴趣的可以去 release 分支查看。
关于前端部分，看到有人呼吁vue，说实话前端技术不是很厉害，本职主要是后端开发，可能达不到预期效果。
所以我准备入坑 Blazor ????，接下来就现学现卖吧，一起学习一起做项目一起进步，加油????
