如何使用 SqlDataProvider 在 Audit.Net 中跟踪事件

问题描述

我正在尝试使用 sqlDataProvider 审核数据库操作。

Global.asax.cs

                Audit.Core.Configuration.DataProvider = new sqlDataProvider()
        {
            ConnectionString =  "...",Schema = "dbo",TableName = "Event",IdColumnName = "EventId",JsonColumnName = "JsonData",LastUpdatedDateColumnName = "LastUpdatedDate",CustomColumns = new List<CustomColumn>()
        {

            new CustomColumn("EventType",ev => ev.EventType),new CustomColumn("ModuleName",ev => "AuditTrail")
        }
        };

如果我添加如下自定义列

    new CustomColumn("StartDate",ev=>ev.StartDate),new CustomColumn("EndDate",ev=>ev.EndDate),new CustomColumn("Duration",ev=>ev.Duration),new CustomColumn("Target",ev=>ev.Target),new CustomColumn("Comments",ev=>ev.Comments),new CustomColumn("Environment",ev=> ev.Environment),

它抛出异常“不存在从对象类型 Audit.Core.AuditEventEnvironment 到已知托管提供程序本机类型的映射”

我如何在此处跟踪事件。 基本上我想将 jasonData 字段值插入到几个字段中。

上下文变化

    public override int SaveChanges()
    {
        return _helper.SaveChanges(_auditContext,() => base.SaveChanges());
    }

    public override async Task<int> SaveChangesAsync(CancellationToken cancellationToken = default(CancellationToken))
    {
        return await _helper.SaveChangesAsync(_auditContext,() => base.SaveChangesAsync(cancellationToken));
    }

解决方法

这是数据类型的问题。 正确的代码应该是

     Audit.Core.Configuration.DataProvider = new SqlDataProvider()
    {
        ConnectionString =  "...",Schema = "dbo",TableName = "Event",IdColumnName = "EventId",JsonColumnName = "JsonData",LastUpdatedDateColumnName = "LastUpdatedDate",CustomColumns = new List<CustomColumn>()
    {

        new CustomColumn("EventType",ev => ev.EventType),new CustomColumn("ModuleName",ev => "AuditTrail"),new CustomColumn("StartDate",ev=>Convert.ToDateTime(ev.StartDate)),new CustomColumn("EndDate",ev=>Convert.ToDateTime(ev.EndDate)),new CustomColumn("Duration",ev=>Convert.ToInt32(ev.Duration)),}
    };

我们可以为json数据字段的一些其他细节添加以下自定义字段。

    new CustomColumn("UserName",ev=> ev.Environment.UserName.ToString()),new CustomColumn("MachineName",ev=> ev.Environment.MachineName.ToString()),new CustomColumn("DomainName",ev=> ev.Environment.DomainName.ToString()),new CustomColumn("CallingMethod",ev=> ev.Environment.CallingMethodName.ToString()),new CustomColumn("DatabaseName",ev=> ev.GetEntityFrameworkEvent().Database.ToString()),

由于json内容的entry在insert和update的时候有点不同，我还是想通过action来分离数据。
