asp.net – 如何从SQL数据库流.flv文件

我在这里使用JW Player,因此“swfobject.js”和“player.swf”

HttpHandler的：

public class ViewFilm : IHttpHandler
{
    public void ProcessRequest(HttpContext context)
    {
        try
        {
            // Check if id was given
            if (context.Request.QueryString["id"] != null)
            {
                string movId = context.Request.QueryString["id"];

                // Connect to DB and get the item id
                using (SqlConnection con = new SqlConnection(ConfigurationManager.ConnectionStrings["ApplicationServices"].ConnectionString))
                using (SqlCommand cmd = new SqlCommand("GetItem",con))
                {
                    cmd.CommandType = CommandType.StoredProcedure;
                    SqlParameter sqlParam = cmd.Parameters.Add("@itemId",SqlDbType.Int);
                    sqlParam.Value = movId;

                    con.Open();
                    using (SqlDataReader dr = cmd.ExecuteReader())
                    {
                        if (dr.HasRows)
                        {
                            dr.Read();
                            // Add HTTP header stuff: cache,content type and length
                            context.Response.Cache.SetCacheability(HttpCacheability.Public);
                            context.Response.Cache.SetLastModified(DateTime.Now);
                            context.Response.AppendHeader("Content-Type","video/x-flv");
                            context.Response.AppendHeader("Content-Length",((byte[])dr["data"]).Length.ToString());
                            context.Response.BinaryWrite((byte[])dr["data"]);
                        }
                    }
                }
            }
        }
        catch (Exception ex)
        {
            throw new Exception(ex.ToString());
        }
    }

    public bool IsReusable
    {
        get { return false; }
    }
}

JavaScript的
该功能将播放器添加到< div id =“video1”>并且可以称为例如当用户单击按钮时.

<script type='text/javascript' src='swfobject.js'></script>
<script type="text/javascript" language="javascript">
function vid() {
  var s1 = new SWFObject('player.swf','player1','480','270','9');
  s1.addParam('allowfullscreen','true');
  s1.addParam('allowscriptaccess','always');
  s1.addVariable('file',encodeURIComponent('ViewFilm.ashx?id=10'));
  s1.addVariable('type','video');
  s1.write(document.getElementById("video1"));
}
</script>
