如何在 asp classic 中触发异步调用并忽略响应? [英] How do I fire an asynchronous call in asp classic and ignore the response?

问题描述

这里是要点:

我想在 asp 中拨打电话，但我不关心响应.我只想触发呼叫，我不希望页面等待响应.根据文档，它应该看起来像这样:

I have a call I want to make in asp, and I do not care about the response. I just want to fire the call and I do not want the page to wait for the response. According to the documentation, it should look something like this:

dim xmlhttp : set xmlhttp = Server.CreateObject("MSXML2.ServerXMLHTTP")
xmlhttp.Open "POST", url, true '' setting the 'asynchronous' option to 'true'
xmlhttp.setRequestHeader "Content-Type", "application/soap+xml; charset=utf-8"
xmlhttp.setRequestHeader "Content-Length", Len(XMLData)
xmlhttp.send XMLData

这在同步调用时效果很好，但是当我将异步选项切换为true"时，什么都不会触发.我可以从互联网上收集到的是用户会执行以下操作:

This works peachy when calling synchronously, but when I flip the ansynchronous option to 'true', nothing fires. What I can gather from the internet is that users do something like the following:

While xmlhttp.readyState <> 4
    xmlhttp.waitForResponse 1000
Wend

如果您正在等待响应，这看起来不再像是一个异步调用，我疯了吗?

Am I crazy in that this does not really seem like an asynchrous call anymore though if you are waiting for a response?

在发送之后放置 xmlhttp.waitForResponse 1 行会导致请求触发，但同样，我不想等待.

putting the line xmlhttp.waitForResponse 1 right after the send will cause the request to fire, but again, I don't want to wait a second.

有什么想法吗?

推荐答案

今天我遇到了同样的问题.我通过使用Microsoft.XMLHTTP"对象解决了它.

Today I got the same issue. I resolved it by using "Microsoft.XMLHTTP" object.

dim xmlhttp 
set xmlhttp = Server.CreateObject("Microsoft.XMLHTTP")
xmlhttp.Open "POST", url, true 
xmlhttp.Send ""

现在请求被异步发送并且目标 URL 被命中.希望对您有所帮助.

And now the request is sent asynchronously and target URL was hit. Hope that helps.
