ashx获取session



要想在ashx文件使用Session，必须实现Session接口（System.Web.SessionState.IRequiresSessionState  ）

eg：

public class Uploader : IHttpHandler,System.Web.SessionState.IRequiresSessionState  {
   
    public void ProcessRequest (HttpContext context) {
        context.Response.ContentType = "text/plain";
        //指定字符集

        context.Response.ContentEncoding = Encoding.UTF8;
        if (context.Request["REQUEST_METHOD"] == "OPTIONS")
        {
            context.Response.End();
        }
       ……
