要根据操作筛选审计事件,可以使用Audit.NET和Entity Framework结合使用。下面是一个示例解决方案的代码:
Install-Package Audit.NET
Install-Package Audit.EntityFramework
AuditDbContext
:using Audit.EntityFramework;
using Microsoft.EntityFrameworkCore;
public class MyAuditDbContext : AuditDbContext
{
public MyAuditDbContext(DbContextOptions options)
: base(options)
{
}
public DbSet AuditLogs { get; set; }
protected override void OnModelCreating(ModelBuilder modelBuilder)
{
modelBuilder.Entity().ToTable("AuditLogs");
}
}
using System;
public class AuditLog
{
public int Id { get; set; }
public string TableName { get; set; }
public string Action { get; set; }
public string AuditData { get; set; }
public DateTime AuditDate { get; set; }
}
Startup.cs
文件中进行配置,将MyAuditDbContext
注册为服务:using Microsoft.EntityFrameworkCore;
public void ConfigureServices(IServiceCollection services)
{
services.AddDbContext(options =>
options.UseSqlServer(Configuration.GetConnectionString("DefaultConnection")));
// Other service configurations
}
Audit.EntityFramework.Configuration.Setup()
方法配置审计选项。可以使用ActionTypeSelector
选项来筛选操作类型:using Audit.Core;
using Audit.EntityFramework;
public class MyService
{
private readonly MyAuditDbContext _dbContext;
public MyService(MyAuditDbContext dbContext)
{
_dbContext = dbContext;
}
public void PerformAction()
{
Audit.EntityFramework.Configuration.Setup()
.ForContext(_dbContext, config => config
.IncludeEntityObjects()
.ActionTypeSelector(ev => ev.Action == "Insert" || ev.Action == "Update"));
// Perform the action that needs to be audited
var auditEvent = new AuditEvent
{
// Set the necessary properties of the audit event
};
_dbContext.AuditLogs.Add(new AuditLog
{
TableName = auditEvent.Target.GetType().Name,
Action = auditEvent.GetEntityFrameworkEvent().Action,
AuditData = auditEvent.ToJson(),
AuditDate = DateTime.Now
});
_dbContext.SaveChanges();
}
}
在上面的示例中,PerformAction()
方法将被审计。通过使用Audit.EntityFramework.Configuration.Setup()
方法,我们配置了MyAuditDbContext
以进行审计,并使用ActionTypeSelector
选项来筛选“Insert”和“Update”操作。在执行需要审计的操作之后,我们创建了一个审计日志实体对象,并将其保存到数据库中。
请注意,这只是一个基本示例,您可能需要根据自己的需求进行调整和扩展。
