我正在尝试为asp.net核心完成的每个日志添加租户名称。 我使用Sasskit进行多租户。
我得到一些范围问题。我希望得到一些关于如何让它发挥作用的反馈:
这是我的自定义记录器:
public class MultiTenantLogger : IMultiTenantProvider
{
private AppTenant _tenant;
public MultiTenantLogger(AppTenant tenant)
{
_tenant = tenant;
}
public string GetTenantName<T>()
{
var typeDisplayName = GetTypeDisplayName(typeof(T));
if (_tenant == null)
{
return typeDisplayName;
}
return $"Tenant: {_tenant.Name}";
}
}
public class MultiTenantLogger<T> : ILogger<T>
{
private readonly ILogger _logger;
public MultiTenantLogger(ILoggerFactory factory, IMultiTenantProvider multiTenantProvider)
{
if (factory == null)
{
throw new ArgumentNullException(nameof(factory));
}
if (multiTenantProvider == null)
{
throw new ArgumentNullException(nameof(multiTenantProvider));
}
var category = multiTenantProvider.GetTenantName<T>();
_logger = factory.CreateLogger(category);
}
IDisposable ILogger.BeginScope<TState>(TState state) => _logger.BeginScope(state);
bool ILogger.IsEnabled(LogLevel logLevel) => _logger.IsEnabled(logLevel);
void ILogger.Log<TState>(LogLevel logLevel,
EventId eventId,
TState state,
Exception exception,
Func<TState, Exception, string> formatter)
=> _logger.Log(logLevel, eventId, state, exception, formatter);
}
这是我的创业公司:
public void ConfigureServices(IServiceCollection services)
{
_services = services;
services.AddMultitenancy<AppTenant, CachingAppTenantResolver>();
services.AddDbContext<ApplicationDbContext>(options =>
options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
services.AddIdentity<ApplicationUser, IdentityRole>()
.AddEntityFrameworkStores<ApplicationDbContext>()
.AddDefaultTokenProviders();
// Add application services.
services.AddTransient<IEmailSender, EmailSender>();
services.Configure<MultitenancyOptions>(Configuration.GetSection("Multitenancy"));
services.AddMvc();
services.AddTransient<IMultiTenantProvider, MultiTenantLogger>();
services.Replace(ServiceDescriptor.Transient(typeof(ILogger<>), typeof(MultiTenantLogger<>)));
}
我收到此错误:
无法使用作用域服务'AspNetMvcSampleModels.AppTenant' 来自singleton'Microsoft.AspNetCore.Hosting.IApplicationLifetime'。
欢迎任何有关如何使其正常工作的反馈!

我认为你需要同时制作Singleton或Scoped
您可以尝试替换
services.AddTransient<IMultiTenantProvider, MultiTenantLogger>();
与
services.AddSingleton<IMultiTenantProvider, MultiTenantLogger>();
