在ASP Classic中可以尝试尝试错误处理吗？ [英] Is try-catch like error handling possible in ASP Classic?

问题描述

在 ASP Classic 中有哪些选项可用于错误处理？

What options are there in ASP Classic for error handling?

例如：

我正在使用 Mail.SendMail 函数，但是打开测试服务器不起作用，这是正常现象。我想测试邮件是否可行，如果不是，然后继续和/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.

任何想法？

推荐答案

有两种方法，您可以在JScript或VBScript中编写具有构造的代码，也可以在代码中进行编码。

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，您可以使用错误恢复，尝试在检查点检查err.Number，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:

<%
Dim i
' Turn on 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 ' But don't let other errors hide!
   ' Code to cope with the error here
End If
On Error Goto 0 ' Reset error handling.
