关于 ashx 的设计

000000000000000000

 

可以将多个操作/方法放到一个ashx文件中，这样便于管理

 

以下代码参考：

public void ProcessRequest(HttpContext context)
        {
            context.Response.ContentType = "text/plain";
            context.Response.Buffer = true;
            context.Response.ExpiresAbsolute = DateTime.Now.AddDays(-1);
            context.Response.AddHeader("pragma", "no-cache");
            context.Response.AddHeader("cache-control", "");
            context.Response.CacheControl = "no-cache";

            try
            {
                if (HttpContext.Current.Request["cmd"] != null)
                {
                    string cmd = HttpContext.Current.Request["cmd"];
                    var method = this.GetType().GetMethod(cmd);
                    if (method != null)
                    {
                        method.Invoke(this, new object[] { context });
                    }
                }
            }
            catch (Exception ex)
            {

            }
        }

            public void Add(HttpContext context)
        {
                  //相关业务      
        }
     public bool IsReusable
        {
            get 
            {
                return false;
            }
        }
