multi-tenant 相关问题

我想将多租户从 5 更新为 7 例子 city-a.site.com city-b.site.com 语境公共类 MemoryDbContext ：DbContext { 公共 MemoryDbContext（DbContextOptions 我想将多租户从 5 更新为 7 示例 city-a.site.com city-b.site.com 背景 public class MemoryDbContext : DbContext { public MemoryDbContext(DbContextOptions<MemoryDbContext> options) : base(options) { } protected MemoryDbContext() { } public DbSet<Tenant> Tenants { get; set; } } 租户属性类 public class TenantAttribute : ActionFilterAttribute { private readonly MemoryDbContext _memoryDbContext; public TenantAttribute(MemoryDbContext memoryDbContext) { _memoryDbContext = memoryDbContext; } public override void OnActionExecuting(ActionExecutingContext actionExecutingContext) { var fullAddress = actionExecutingContext.HttpContext?.Request? .Headers?["Host"].ToString()?.Split('.'); if (fullAddress.Length < 2) { //Redirect WWW var redirectUrl = "https://www.example.com"; actionExecutingContext.Result = new RedirectResult(redirectUrl, true); } else { var subdomain = fullAddress[0]; var tenant = _memoryDbContext.Tenants .SingleOrDefault(t => string.Equals(t.Host, subdomain, StringComparison.OrdinalIgnoreCase)); if (tenant != null) { actionExecutingContext.RouteData.Values.Add("tenant", tenant); base.OnActionExecuting(actionExecutingContext); } else { //Redirect WWW var redirectUrl = "https://www.example.com"; actionExecutingContext.Result = new RedirectResult(redirectUrl, true); } } } } 型号 public class Tenant { public int Id { get; set; } public string Name { get; set; } public string Host { get; set; } //City Or Group public int Cog { get; set; } public int MainId { get; set; } public string SubId { get; set; } } 定制服务 services.AddScoped(typeof(TenantAttribute)); 配置服务 services.AddDbContext<MemoryDbContext>(options => options.UseInMemoryDatabase("MemoryDb")); 曾在 .net 5 工作过 public static void Main(string[] args) { var host = CreateHostBuilder(args).Build(); using (var scope = host.Services.CreateScope()) { var services = scope.ServiceProvider; var context = services.GetRequiredService<MemoryDbContext>(); context.Database.EnsureCreated(); if (!context.Tenants.Any()) { context.Tenants.Add(new Tenant() { Name = "City1", Host = "city-a", Cog = 2, MainId = 1, SubId = "1" }); context.Tenants.Add(new Tenant() { Name = "City2", Host = "city-b", Cog = 2, MainId = 2, SubId = "2" }); context.SaveChanges(); } } host.Run(); } 我在 .NET 7 中尝试过： var builder = WebApplication.CreateBuilder(args); ConfigureLogging(builder.Logging, builder.Environment, builder.Configuration); ConfigureServices(builder.Services, builder.Configuration, builder.Environment); var host = Host.CreateDefaultBuilder(args).Build(); using (var scope = host.Services.CreateScope()) { scope.RunScopedServicec<MemoryDbContext>(); var services = scope.ServiceProvider; var context = services.GetRequiredService<MemoryDbContext>(); context.Database.EnsureCreated(); if (!context.Tenants.Any()) { context.Tenants.Add(new Tenant() { Name = "City1", Host = "city-a", Cog = 2, MainId = 1, SubId = "1" }); context.Tenants.Add(new Tenant() { Name = "City2", Host = "city-b", Cog = 2, MainId = 2, SubId = "2" }); context.SaveChanges(); } } host.Run(); var webApp = builder.Build(); 错误系统无效操作异常 H结果=0x80131509 消息=未注册类型“Site.DataLayer.Context.MemoryDbContext”的服务。来源=Microsoft.Extensions.DependencyInjection.Abstractions 堆栈跟踪：在 Microsoft.Extensions.DependencyInjection.ServiceProviderServiceExtensions.GetRequiredService（IServiceProvider 提供程序，类型 serviceType）在 Microsoft.Extensions.DependencyInjection.ServiceProviderServiceExtensions.GetRequiredService[T]（IServiceProvider 提供程序）在计划中。试试这个： var builder = WebApplication.CreateBuilder(args); ConfigureLogging(builder.Logging, builder.Environment, builder.Configuration); ConfigureServices(builder.Services, builder.Configuration, builder.Environment); var webApp = builder.Build(); using (var scope = webApp.Services.CreateScope()) { scope.RunScopedServicec<MemoryDbContext>(); var services = scope.ServiceProvider; var context = services.GetRequiredService<MemoryDbContext>(); context.Database.EnsureCreated(); if (!context.Tenants.Any()) { context.Tenants.Add(new Tenant() { Name = "City1", Host = "city-a", Cog = 2, MainId = 1, SubId = "1" }); context.Tenants.Add(new Tenant() { Name = "City2", Host = "city-b", Cog = 2, MainId = 2, SubId = "2" }); context.SaveChanges(); } } webApp.Run();
