是的try-catch类似的错误在ASP经典的处理可能吗？ [英] Is try-catch like error handling possible in ASP Classic?

问题描述

哪些选项中有 ASP经典错误处理？

What options are there in ASP Classic for error handling?

例如：

我使用了 Mail.SendMail 的功能，但在测试服务器上进行切换时它不工作，这是正常的。我想测试，如果邮件是可能的，如果没有则继续和/或显示的消息。

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，你可以美元的JScript或VBScript C $ç这确实有构造或者你可以在你的code做傻事了。

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你会使用下列类型的构造：

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

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

在你的ASP code，你通过像抓点上使用错误的简历在旁边点，你就会有一个尝试和检查Err.Number的捏造吧：

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.
