Bizer

Bizer.Core 用于定义前后端 HTTP 的解析规范。 根据需要安装:

  • 动态 HTTP 客户端 Bizer.Client: 根据接口的 HTTP 定义,自动发送 Http 请求
  • 动态 API 服务端 Bizer.AspNetCore: 根据接口的 HTTP 定义,自动变成 WEB API 接口

🌈 优势

  • 只需要定义一套接口,就可以完成前后端对接,减少重复工作量,不再担心 API 接口的规范不一致;
  • 完美兼容任意项目,只需要给接口定义框架的 HTTP 规范即可;
  • 非常灵活,可以将接口和实现作为普通的方法,根据选择配套安装 Bizer.AspNetCoreBizer.Client 即可实现动态 API 或动态 Http 的功能;

快速上手

⚠️ 定义服务接口和 HTTP 路由规则

安装 Bizer

> Install-Package Bizer

定义接口

+[ApiRoute("api/account")] //定义 API 的路由基础路由
public interface IAccountService
{
+	[Post] //定义为 Post 请求
	Task<Returns<string>> SignInAsync([Form]string userName, [Form]string password); //参数使用 form 方式

+ 	[Get("{id}")]//定义 Get 请求,路由为:api/account/{id}
	Task<MyData> GetAsync(int id);

+	[Put("student/{id}")] // 定义 Put 请求,路由为:api/account/{id}
	Task UpdateStudentAsync([Body]Student model, int id);
}

实现接口

public class AccountApplicationService : IAccountService
{
	public Task<Returns<string>> SignInAsync(string userName, string password)
	{
		//...业务逻辑代码
		return Returns<string>.Success(token);
	}

	//...其他实现

	[Authorize(Roles = "admin")] //兼容 Microsoft.AspNetCore.Authorization 认证授权框架
	Task UpdateStudentAsync([Body]Student model, int id)
	{
		//...
	}
}

📌 动态 WEB API

在 ASP.NET CORE 项目中安装 Bizer.AspNetCore

> Install-Package Bizer.AspNetCore

配置服务

builder.Services
	.AddBizer(options => options.AddAssembly(typeof(AccountService).Assembly)) //接口实现类所在的程序集
+	.AddDynamicWebApi(); //将扫描到的程序集的接口和实现秒变动态 WEB API 服务

自行安装相关的 Swagger 包即可看到生成的 API or 通过 Postman 来模拟发送 HTTP 测试 API 接口

🛡️ 动态 Http 代理

安装 Bizer.Client

> Install-Package Bizer.Client

配置要作为动态 HTTP 代理所在接口的程序集

builder.Services
	.AddBizer(options => options.AddAssembly(typeof(IAccountService).Assembly)) //要扫描的程序集
+	.AddDynamicHttpProxy("http://{localhost}:{port}"); // 将扫描到的程序集的接口秒变动态 HTTP 代理

在任意地方调用接口方法:

private readonly IAccountService _accountService;
public MyClientService(IAccountService accountService)
{
	_accountService = accountService;
}
//...
public async Task ProcceedAsync()
{
	var result = _accountService.SignInAsync("admin", "password");
	if(!result.Succeed)
	{
		//result.Errors 获取错误信息
	}

	var data = result.Data; //获取数据
}

❓ Q & A

  • 为什么我的接口没有识别成 API? 只有接口定义了 ApiRouteAttribute 特性,才会被自动识别动态 API 或 HTTP 代理
  • 我接口定义了 ApiRouteAttribute 特性,但是方法却没有识别成 API 接口中定义的方法,需要定义请求类型才会被正确识别成 API

🎬 扩展

扩展可以根据自己的需要安装

Bizer.Extensions.AutoInjection

实现接口的自动化注入。接口中使用 InjectServiceAttribute 即可:

+[InjectService] //默认是 Scoped
public interface IMyService { }

+[InjectService(Lifetime = ServiceLifetime.Transient)] //注册成 Transient 生命周期
public interface IMyService { }

添加扩展模块:

builder.Services.AddBizer(...)
+		.AddServiceInjection() //扫描到的程序集中,接口定义了 InjectService 特性都会被添加成服务(IoC)

Bizer.Extensions.ApplicationService.EntityFrameworkCore

基于 EntityFrameworkCore 实现的应用服务,并使用 Mapster 实现对象映射。

类似于 Abp 的 ApplicationService 层,但比它更简单。

builder.Services.AddBizer(...)
+		.AddMapster() //添加 Mapster 服务

		//使用内置的 BizerDbContext 作为项目
+		.AddDbContext(options => options.UseSqlServer("...")) 

		//或者使用自定义的 DbContext,要求继承自 BizerDbContext
+		.AddDbContext<MyDbContext>(options => options.UseSqlServer("..."))
  • 接口可以继承自 IQueryService(只读查询服务) 或 ICrudService(CRUD 服务)
public interface IUserQueryService : IQuerySerivce<Guid, UserQueryDto> { }

public interface IUserService : ICrudService<Guid, UserQueryDto, UserListDto, UserCreateDto, UserUpdateDto>
  • 对应实现则是 QueryServiceBaseCrudServiceBase 两个基类
public class UserQueryService : IUserQueryService, QueryServiceBase<Guid, User, UserQueryDto> 
{ 
	//...
}

public class UserService : IUserService, CrudServiceBase<Guid, User, UserQueryDto, UserListDto, UserCreateDto, UserUpdateDto>
{
	//...
}
  • 实体的配置需要实现接口 IEntityTypeConfiguration<TEntity> 使用 FluentAPI 配置
public class UserConfiguration : IEntityTypeConfiguration<User>
{
	public void Configure(ModelBuilder<User> builder)
	{
		builder.HasKey(m=>m.Id);
		builder.Property(m=>m.Name).IsRequired();
		//...
		builder.ToTable("MyUserTable");
	}
}

内置的 BizerDbContext 会自动根据程序集将实现 IEntityTypeConfiguration<TEntity> 的配置加入到 DbContext,无需添加 DbSet

有关 EntityFrameworkCore 的 Fluent API 配置

  • 你也可以实现自己的 DbContext,或继承自 BizerDbContext,如果不继承 BizerDbContext 就不会有自动配置功能,可按照常规方式自己添加或用 DbSet
public class AppDbContext : DbContext
{
	public AppDbContext(DbContextOptions options) : base(options) { }

	public DbSet<User> Users { get; set; }
}

那么 QueryServiceBaseCrudServiceBase 需要显示地指定你的 DbContext 对象:

+ public class UserQueryService : IUserQueryService, QueryServiceBase<AppDbContext, Guid, User, UserQueryDto> 
- public class UserQueryService : IUserQueryService, QueryServiceBase<Guid, User, UserQueryDto> 
{ 
	//...
}

+ public class UserService : IUserService, CrudServiceBase<AppDbContext, Guid, User, UserQueryDto, UserListDto, UserCreateDto, UserUpdateDto>
- public class UserService : IUserService, CrudServiceBase<Guid, User, UserQueryDto, UserListDto, UserCreateDto, UserUpdateDto>
{
	//...
}

最终在 Program.cs 中修改

builder.Services.AddBizer(...)
		.AddMapster()
-		.AddDbContext(options => options.UseSqlServer("...")) 
+		.AddDbContext<AppDbContext>(options => options.UseSqlServer("..."))
