.NET /软硬度：如何从阅读的URLRequest部分结果？ [英] .Net/Flex: How to read partial results from URLRequest?

问题描述

我正在这与Flex的执行的批处理程序脚本。批处理脚本是在.aspx页面中，并通过以下类返回部分结果：

I'm working on a batch process script that's executed from Flex. The batch script is in a .aspx Page and returns partial results through the following class:

public class ResponseLogger
{

    private HttpResponse _response;

    public ResponseLogger(HttpResponse response)
    {
        this._response = response;
    }

    public void Start()
    {
        _response.Clear();
        _response.ContentType = "text/plain";
        _response.ContentEncoding = System.Text.Encoding.GetEncoding("ISO-8859-1");
    }

    public void End()
    {
        _response.End();
    }

    public void Br()
    {
        Log("");
    }

    public void Underline(string message)
    {
        Log(message);
        Log("".PadLeft(message.Length, '-'));

    }

    public void Log(string message)
    {
        _response.Write(message + "\n");
        _response.Flush();
    }

}

在我的Flex应用程序，我想尽快，因为它是刷新在服务器端显示的结果。可以这样做使用ActionScript？

In my Flex application I'd like to show the result as soon as it's flushed on server side. Can this be done using Actionscript?

推荐答案

简短的回答，不，你不能，除非你做短/长轮询（每分钟几个HTTP调用）做主持HTTP部分结果。 HTTP在它的本质是一个请求 - 响应协议。

Short answer, no, you cannot do partial results over HTTP unless you do short/long polling (several http calls per minute). HTTP in it's essence is a request-response protocol.

你想要的是一个推送技术，但我不知道是否有一个.NET相当于此。在Java方面，你得到的BlazeDS和GraniteDS的推送消息。

What you want is a push technology, but I'm not sure if there's a .NET equivalent for this. On the Java side you got BlazeDS or GraniteDS for push messaging.

另一个问题是，你为什么结果部分？​​

The other question is why are you results 'partial'?
