[从0到1搭建ABP微服务] - 搭建租户管理服务

一、简介

ABP模板项目中已经提供了租户登录和管理功能,但是模板项目是单体应用结构,无法单独部署租户服务,所以难以满足微服务的需求。本篇文章将会介绍搭建ABP租户管理服务,并单独部署应用。

二、创建工程

2.1 创建TenantService.Host服务

微服务的开发应该是模块化的,所以TenantService.Host服务名没有放在在ABP微服务解决方案中,选择独立搭建、独立部署的方式。

三、安装模块组件

在大型团队中或者小型精英团队中建议拉取将ABP源码发布本地Nuget包,所有服务引用本地包进行开发。因为无论ABP如何通用也是无法满足企业级后台业务的发展和版本迭代的,有老司机的团队应该要掌握修改ABP底层应用甚至底层框架的能力。

3.1 安装ids4、.net core、ABP等必须组件

  • Serilog.Extensions.Hosting Version="3.0.0"
  • Serilog.Sinks.File Version="4.0.0"
  • Serilog.Sinks.Elasticsearch Version="6.5.0"
  • Swashbuckle.AspNetCore Version="5.0.0-rc4"
  • IdentityServer4.AccessTokenValidation Version="3.0.0"
  • Microsoft.Extensions.Caching.StackExchangeRedis Version="3.1.0"
  • Microsoft.AspNetCore.DataProtection.StackExchangeRedis Version="3.1.0"
  • Volo.Abp.AspNetCore.MultiTenancy Version="2.0.1"
  • Volo.Abp.AuditLogging.EntityFrameworkCore Version="2.0.1"
  • Volo.Abp.Autofac Version="2.0.1"
  • Volo.Abp.EntityFrameworkCore.SqlServer Version="2.0.1"
  • Volo.Abp.PermissionManagement.EntityFrameworkCore Version="2.0.1"
  • Volo.Abp.SettingManagement.EntityFrameworkCore Version="2.0.1"
  • Volo.Abp.TenantManagement.Application Version="2.0.1"
  • Volo.Abp.TenantManagement.EntityFrameworkCore Version="2.0.1"
  • Volo.Abp.TenantManagement.HttpApi Version="2.0.1"
  • Volo.Abp.Identity.Application.Contracts Version="2.0.1"
  • Volo.Abp.Identity.EntityFrameworkCore Version="2.0.1"
  • volo.abp.identityserver.entityframeworkcore Version="2.0.1"

四、配置Module

ABP不仅基于DDD设计,更是基于模块化实现的。

4.1 添加TenantServiceHostModule

在TenantService.Host根目录中添加TenantServiceHostModule

4.2 引用依赖

租户服务关系的ABP应用模块比较多,所以依赖也比其他服务多一些。ABP模块引用会在服务模块启动时载入IOC容器,这样的好处是无需多次引用,只要在Mudule中引用一次就可以。
引用的依赖顺序如下:
AbpAutofacModule
AbpEventBusRabbitMqModule
AbpAspNetCoreMultiTenancyModule
AbpEntityFrameworkCoreSqlServerModule
AbpAuditLoggingEntityFrameworkCoreModule
AbpPermissionManagementEntityFrameworkCoreModule
AbpSettingManagementEntityFrameworkCoreModule
AbpTenantManagementHttpApiModule
AbpTenantManagementEntityFrameworkCoreModule
AbpTenantManagementApplicationModule
AbpIdentityEntityFrameworkCoreModule
AbpIdentityServerEntityFrameworkCoreModule

4.3 注册服务

与其他服务一样需要注册认证、Swagger、默认语言、数据库服务、redis等,这里就不过多赘述了,ABP文档有详细的解释。

4.4 配置初始化模块

这里也跟其他服务一样,没有特殊的模块需要初始化。

4.5 TenantServiceHostModule完整代码如下:

        typeof(AbpIdentityServerEntityFrameworkCoreModule)
        )]
    public class TenantServiceHostModule: AbpModule
    {
        public override void ConfigureServices(ServiceConfigurationContext context)
        {
            var configuration = context.Services.GetConfiguration();

            context.Services.AddAuthentication("Bearer")
                .AddIdentityServerAuthentication(options =>
                {
                    options.Authority = configuration["AuthServer:Authority"];
                    options.ApiName = configuration["AuthServer:ApiName"];
                    options.RequireHttpsMetadata = false;
                });

            context.Services.AddSwaggerGen(options =>
            {
                options.SwaggerDoc("v1", new OpenApiInfo { Title = "Tenant Service API", Version = "v1" });
                options.DocInclusionPredicate((docName, description) => true);
                options.CustomSchemaIds(type => type.FullName);
            });

            Configure<AbpLocalizationOptions>(options =>
            {
                options.Languages.Add(new LanguageInfo("en", "en", "English"));
            });

            Configure<AbpDbContextOptions>(options =>
            {
                options.UseSqlServer();
            });

            context.Services.AddStackExchangeRedisCache(options =>
            {
                options.Configuration = configuration["Redis:Configuration"];
            });

            Configure<AbpAuditingOptions>(options =>
            {
                options.IsEnabledForGetRequests = true;
                options.ApplicationName = "TenantService";
            });

            var redis = ConnectionMultiplexer.Connect(configuration["Redis:Configuration"]);
            context.Services.AddDataProtection()
                .PersistKeysToStackExchangeRedis(redis, "DataProtection-Keys");
        }

        public override void OnApplicationInitialization(ApplicationInitializationContext context)
        {
            var app = context.GetApplicationBuilder();

            app.UseCorrelationId();
            app.UseVirtualFiles();
            app.UseRouting();
            app.UseAuthentication();

            app.Use(async (ctx, next) =>
            {
                var currentPrincipalAccessor = ctx.RequestServices.GetRequiredService<ICurrentPrincipalAccessor>();
                var map = new Dictionary<string, string>()
                {
                    { "sub", AbpClaimTypes.UserId },
                    { "role", AbpClaimTypes.Role },
                    { "email", AbpClaimTypes.Email },
                };
                var mapClaims = currentPrincipalAccessor.Principal.Claims.Where(p => map.Keys.Contains(p.Type)).ToList();
                currentPrincipalAccessor.Principal.AddIdentity(new ClaimsIdentity(mapClaims.Select(p => new Claim(map[p.Type], p.Value, p.ValueType, p.Issuer))));
                await next();
            });

            app.UseAbpRequestLocalization(); 
            app.UseSwagger();
            app.UseSwaggerUI(options =>
            {
                options.SwaggerEndpoint("/swagger/v1/swagger.json", "Tenant Service API");
            });
            app.UseAuditing();
            app.UseMvcWithDefaultRouteAndArea();

            AsyncHelper.RunSync(async () =>
            {
                using (var scope = context.ServiceProvider.CreateScope())
                {
                    await scope.ServiceProvider
                        .GetRequiredService<IDataSeeder>()
                        .SeedAsync();
                }
            });
        }
    }
}

五、管理租户

5.1 启动TenantService.Host服务

Ctrl+F5启动即可,启动成功后可以看到Swagger跳转。

此时ABP已经将租户的权限种子数据添加到数据库。

5.2 添加租户

使用POST请求添加Default租户

请求成功并返回租户信息:

此时ABP已经自动添加Dfault租户的admin用户、角色和权限。

5.3 使用租户登录

在AuthServer中使用Default获取token

可以看出租户已经启用并成功登录,而且token中已经包含tenant

六、总结

ABP社区版中的租户功能有点弱,应付中小型项目是绰绰有余的,对于大型SaaS系统笔者还是建议购买商业版以获得更大的支持。ABP的租户还有更多的配置,如租户独立数据库等,在搭建成功租户服务后可以一步步尝试更多的ABP特性。
