我'创建一个日志,我需要检索请求体以保存在db中.我用HttpActionContext创建了一个过滤器.我尝试通过filterContext.Request.Content.ReadAsStringAsync()恢复.但它总是给我一个空字符串.

LogFilter.cs

public override void OnActionExecuting(HttpActionContext filterContext)
    {
        try
        {
            Task<string> content = filterContext.Request.Content.ReadAsStringAsync();
            string body = content.Result;

            logModel.RequestLog rl = new logModel.RequestLog();
            rl.IP = ((HttpContextWrapper)filterContext.Request.Properties["MS_HttpContext"]).Request.UserHostAddress;
            rl.Type = filterContext.ControllerContext.RouteData.Values["controller"].ToString().ToUpper();
            rl.URL = filterContext.Request.RequestUri.OriginalString;
            rl.Operation = filterContext.Request.Method.Method;
            rl.RequestDate = DateTime.Now;


            filterContext.ControllerContext.RouteData.Values.Add("reqID", new deviceLog.RequestLog().Add(rl).ID.ToString());
        }
        catch { }
        //return new deviceLog.RequestLog().Add(rl);
        base.OnActionExecuting(filterContext);
    }

我正在尝试从DataTableSQL Server 中的表中批量插入，但在我的数据表中没有 id 列。当我调用该WriteToServer方法时，它会抛出异常并显示消息

无法在列 id 中插入 null

代码：

CREATE TABLE [dbo].[TBL_HISTORY]
(
    [ID] [int] IDENTITY(1,1) NOT NULL,
    [VAR1] [int] NOT NULL,
    [VAR2] [datetime] NOT NULL,
    [VAR3] [smallint] NOT NULL
)

我的数据表有以下数据

[VAR1], [VAR2], [VAR3]

C#代码：

using(SqlBulkCopy bulk = new SqlBulkCopy(this.mConnection,SqlBulkCopyOptions.UseInternalTransaction | SqlBulkCopyOptions.KeepIdentity, null))
{
    bulk.DestinationTableName = ToTable;

    bulk.WriteToServer(dt);    // here exception is thrown
}
