ASP.NET 核心实体变更历史

Question

我有很多这样的控制器：

public class EntityController : Controller
{
    private readonly IEntityRepository _entity;

    public EntityController(IEntityRepository entity)
    {
        _entity = entity;
    }

    [Authorize]
    [HttpPut("{id}")]
    public async ValueTask<IActionResult> Put(int id, [FromBody] Entity entity)
    {
        if (entity == null || entity.Id != id) return BadRequest();
        var updated = await _entity.Update(entity);
        if (updated == null) return NotFound();
        return Ok(updated);
    }
}

我需要实现实体编辑（审计）历史记录。

而且，由于该方法被标记为 [Authorize]，我需要记录它是由哪个用户编辑的。我正在查看 Audit.NET，但我没有找到方法。

Audit.NET EF Provider allows to customize the audit entity before saving it. This has to be done at the startup with a so-called AuditEntity Action：为每个被修改的实体触发的动作。

因此，您可以使此操作从当前 HttpContext 中检索用户名并将其存储在审核实体的 UserName 属性中。

在您的 asp 网络启动代码中，设置获取当前 HttpContext 的方法并配置从上下文中检索用户名的操作：

public class Startup
{
    public void ConfigureServices(IServiceCollection services)
    {
        // Add the HttpContextAccessor if needed.
        services.TryAddSingleton<IHttpContextAccessor, HttpContextAccessor>();

        // Get the service provider to access the http context
        var svcProvider = services.BuildServiceProvider();

        // Configure Audit.NET
        Audit.Core.Configuration.Setup()
            .UseEntityFramework(x => x
                .AuditTypeNameMapper(typeName => "Audit_" + typeName)
                .AuditEntityAction((evt, ent, auditEntity) =>
                {
                    // Get the current HttpContext 
                    var httpContext = svcProvider.GetService<IHttpContextAccessor>().HttpContext;
                    // Store the identity name on the "UserName" property of the audit entity
                    ((dynamic)auditEntity).UserName = httpContext.User?.Identity.Name;
                }));
    }
}

这是假设您的审计实体具有共同的 UserName 属性。

如果您的审计实体已经继承自接口或基础 class，包括用户名，您可以改用通用 AuditEntityAction<T>。

Audit.Core.Configuration.Setup()
    .UseEntityFramework(x => x
        .AuditTypeNameMapper(typeName => "Audit_" + typeName)
        .AuditEntityAction<IUserName>((evt, ent, auditEntity) =>
        {
            var httpContext = svcProvider.GetService<IHttpContextAccessor>().HttpContext;
            auditEntity.UserName = httpContext.User?.Identity.Name;
        }));

在 IOC 中获取 UserID :

var userId = httpContextAccessor.HttpContext.User.FindFirst(ClaimTypes.NameIdentifier).Value
