asp.net样板，扩展审计日志

Question

我正在尝试扩展ASPNETBOILETPLATE中的AuditLog实体框架，以便为其添加一些新属性。我试图扩展AuditLog类(ExtendedAuditInfo)并实现AuditStore类(ExtendedAuditStore)的定制版本。但是，我无法在构造函数中注入新的ExtendedAuditInfo，并收到关于Constructor和SaveAsync方法中不匹配输入参数的两条错误消息。

<<p>类strong> ExtendedAuditInfo :

public class ExtendedAuditInfo : AuditInfo
{
// Some properties
}

<<p>类strong> ExtendedAuditStore :

public class ExtendedAuditStore : AuditingStore
{
public ExtendedAuditStore(IRepository<ExtendedAuditInfo, long> auditLogRepository)
: base(auditLogRepository)
{
}
public override Task SaveAsync(ExtendedAuditInfo auditInfo)
{
if (!string.IsNullOrEmpty(auditInfo.Parameters) && auditInfo.Parameters != "{}")
{
var parameters = JsonConvert.DeserializeObject<AuditParameterInput>(auditInfo.Parameters);
if (parameters != null)
auditInfo.CustomData = parameters.Input.Id.ToString();
}
return base.SaveAsync(auditInfo);
}
}

错误如下:

无法从' abp . domain . repository . irepository

我根据如何扩展现有实体的官方文档找到了解决方案。

为了扩展AuditLog类，必须使用继承。因此，一个新的类，假设ExtendedAuditInfo需要从AuditLog继承。

public class ExtendedAuditLog : AuditLog
{
public ExtendedAuditLog()
{
}
public ExtendedAuditLog(AuditInfo auditInfo)
{
this.BrowserInfo = auditInfo.BrowserInfo;
this.ClientIpAddress = auditInfo.ClientIpAddress;
this.ClientName = auditInfo.ClientName;
this.CustomData = auditInfo.CustomData;
this.Exception = auditInfo.Exception?.Message.ToString() + "";
this.ExecutionDuration = auditInfo.ExecutionDuration;
this.ExecutionTime = auditInfo.ExecutionTime;
this.ImpersonatorTenantId = auditInfo.ImpersonatorTenantId;
this.ImpersonatorUserId = auditInfo.ImpersonatorUserId;
this.MethodName = auditInfo.MethodName;
this.Parameters = auditInfo.Parameters;
this.ReturnValue = auditInfo.ReturnValue;
this.ServiceName = auditInfo.ServiceName;
this.TenantId = auditInfo.TenantId;
this.UserId = auditInfo.UserId;
}
//new properties
}

该类必须添加到上下文中，显然，为了添加新属性，需要运行新的迁移。

public class ProjectDbContext : AbpZeroDbContext<Tenant, Role, User, ProjectDbContext >
{
/* Define a DbSet for each entity of the application */

public SerafinaDbContext(DbContextOptions<SerafinaDbContext> options)
: base(options)
{
}
public virtual DbSet<County> Counties { get; set; }
public virtual DbSet<Country> Countries { get; set; }
public virtual DbSet<Currency> Currencies { get; set; }
public virtual DbSet<OrganisationType> OrganisationTypes { get; set; }
public virtual DbSet<ExtendedAuditLog> ExtendedAuditLogs { get; set; }
}

最后，在ExtendedAuditStore类中，IRepository<ExtendedAuditLog, long> _extendedAuditLogRepository必须作为构造函数的第二个参数注入，并可用于插入扩展实体。

public class ExtendedAuditStore : AuditingStore
{
IRepository<ExtendedAuditLog, long> _extendedAuditLogRepository;
public ExtendedAuditStore(
IRepository<AuditLog, long> auditLogRepository,
IRepository<ExtendedAuditLog, long> extendedAuditLogRepository
)
: base(auditLogRepository)
{
_extendedAuditLogRepository = extendedAuditLogRepository;
}
public override async Task SaveAsync(AuditInfo auditInfo)
{
if (auditInfo.Exception != null)
await base.SaveAsync(auditInfo);
var auditLog = new ExtendedAuditLog(auditInfo);
//new properties can be set here
await _extendedAuditLogRepository.InsertAsync(auditLog);
}
}

此外，可以创建IAuditingStore的新实现并将其注入到应用程序服务中，而不是继承AuditingStore。

更新:

最后，您所需要的就是替换StartUp类中的默认AuditingStore:

public IServiceProvider ConfigureServices(IServiceCollection services)
{
services.AddTransient<IAuditingStore, ExtendedAuditStore>();
}
