在 ASP Classic 中是否可以进行 try-catch 之类的错误处理? [英] Is try-catch like error handling possible in ASP Classic?

问题描述

ASP Classic 中有哪些用于错误处理的选项?

What options are there in ASP Classic for error handling?

例如:

我正在使用 Mail.SendMail 功能，但是在打开测试服务器时它不起作用，这是正常的.我想测试是否可以邮寄，如果不能，则继续和/或显示一条消息.

I'm using the Mail.SendMail function but when switching on the testing server it doesn't work, which is normal. I want to test if mailing is possible, if not then continue and/or show a message.

有什么想法吗?

推荐答案

有两种方法，您可以在 JScript 或 VBScript 中编写代码，它们确实具有构造，或者您可以在代码中捏造它.

There are two approaches, you can code in JScript or VBScript which do have the construct or you can fudge it in your code.

使用 JScript，您将使用以下类型的构造:

Using JScript you'd use the following type of construct:

<script language="jscript" runat="server">
try  {
    tryStatements
}
catch(exception) {
    catchStatements
}
finally {
    finallyStatements
}
</script>

在您的 ASP 代码中，您可以通过使用 on error resume next 在您尝试并检查 err.Number 的捕获点来伪造它，例如:

In your ASP code you fudge it by using on error resume next at the point you'd have a try and checking err.Number at the point of a catch like:

<%
' Turn off error Handling
On Error Resume Next


'Code here that you want to catch errors from

' Error Handler
If Err.Number <> 0 Then
   ' Error Occurred - Trap it
   On Error Goto 0 ' Turn error handling back on for errors in your handling block
   ' Code to cope with the error here
End If
On Error Goto 0 ' Reset error handling.
