在 IVR 系统的 apsx 页面中打开/关闭数据库连接
我目前正在开发一个 IVR 系统,我的问题更多是关于基本架构和打开/关闭数据库连接的开发方面。正如您从下面的代码中看到的,在 page_load 中我打开一个连接,传递变量,然后关闭连接。我的问题在于,变量不是在页面加载期间设置的,而是在调用进入时设置的,位于 Boolean ParseXML 部分。我需要知道在页面加载期间打开连接的最佳方式是什么,在收集变量后传递变量,然后最终关闭连接。最重要的是如何做到这一点,我尝试了几种不同的方法,但没有成功。
我最初的思考过程和方法是拆分数据库连接代码,并将它们放置在页面生命周期的不同部分。但我在准确放置它的位置方面取得了零成功。
布尔解析,写入文本文件。但我希望它也写入数据库。

I am currently developing an IVR system, my question is more on a development side of basic architecture and opening/closing a database connection. As you can see from the code below, in the page_load I am opening a connection, passing variables, and then closing the connection. My problem lies in the fact that the variables are not set during the page load, they are set as the call comes in, which is in the Boolean ParseXML section. I need to know what is the best way of opening the connection during page load, pass the variables after they are collected, and then finally close the connection. And most important how to do this, I have tried several different methods, with no success.
My initial thought process and approach is to split up the database connection code, and place them in different parts of the page life cycle. But I have had zero success with where to exactly put it.
The Boolean parse, writes to a text file. But I want it to also write to a database.

我假设在调用 ParseXml 方法后正在使用 SqlDataAdapter。请尝试以下操作:

I am assuming that the SqlDataAdapter is being used after the ParseXml method is called. Try the following:

我没有太多 IVR 经验,但以下是它在我工作的一个系统(使用 VXML)上的工作原理。
IVR 应答了呼叫。这导致 IVR 语音浏览器向 Web 服务器发出 HTTP 请求。
Web 服务器收到请求以及端口号,以识别唯一的呼叫者。就我而言,我们使用输出 VMXL(而不是 HTML 或 XHTML)的标准 ASPX 页面,因此所有处理都必须在 Page_Load 方法中完成。如果页面需要有关呼叫的其他信息(例如呼叫者号码),我们将向 IVR 发出 Web 服务呼叫,包括端口号。
所有与 IVR 的用户交互(按下按钮等)均在 IVR 上处理,并且 Web 服务器仅在请求不同的 VXML 文档时才会参与。
I don't have a lot of IVR experience, but here's how it worked on one system I worked on (which used VXML).
The call was answered by the IVR. This caused the IVR Voice Browser to issue an HTTP request to the web server.
The web server received the request, along with a port number, to identify the unique caller. In my case, we were using standard ASPX pages that output VMXL (rather than HTML or XHTML), so all processing had to be done in the Page_Load method. If the page needed additional information about the call, for example the callers number, we would issue a web services call to the IVR, including the port number.
All of the user interaction with the IVR - button presses, etc - were handled on the IVR, and the web server would only get involved when a different VXML document was requested.
