ASP经典最佳实践 [英] ASP Classic Best Practices
问题描述
大家好，
我是一名拥有超过1,5年经验的ASP开发人员。偷偷摸摸了一下后来我的ASP经典世界有点不满意我的ASP代码
做法所以我想从高级/得到一些建议专业用户...
一些可以帮助我成长的建议！
我知道很多（如果不是全部）那些麻烦的东西在ASP 3中已经在ASP.NET / VS.NET（我正在研究）中更正了
但是ASP 3仍然会在很长一段时间内被b / b
（至少在Win2k3的所有生命周期中）所以我认为
仍然值得知道如何在ASP 3中正确编程。
所以这里是我的问题
- 您如何设计多层Web应用程序？什么需要进入
数据/业务/表示层？否则（如果3层对你来说太过分了，
就像我写的东西一样）你如何构建你的应用程序？
你在哪里放代码，等等...？
- 你如何访问数据库？你有自定义类来访问
数据，检索记录集吗？
- 你有没有用于显示/编辑/排序数据的数据网格类？
- 你是否将数据库连接存储为应用程序变量？
- 有用组件的一些链接（最好免费！）
- 还有其他吗？
非常感谢你关注这篇文章。

从不！

我在客户端尽可能多地进行验证。这样，用户
立即得到反馈，而不是等待往返服务器。
此外，这意味着您的Web服务器收费会减少，特别是如果你的用户
base包含大比例的numbskulls（或者如果你的表单不是很好的b $ b设计:-)。
但是，我认为在服务器端进行验证也很重要（对于
格式问题，在ASP中;对于数据违规，在SQL Server中）。应该
永远不会让坏数据进入系统，而狡猾的用户可以通常找到绕过客户端验证的方法。
Hi all,
i am an ASP developer with 1,5+ years experience. After sneaking around the
ASP Classic world for a bit i became a bit dissatisfied of my ASP code
practices so i''d like to have some advice from the advanced/pro users...
some advice that would help me to grow up!
I know that many (if not all) the stuff that was a hassle in ASP 3 has been
corrected in ASP.NET/VS.NET (which i''m studying) but ASP 3 will still be
around for a long time (at least for all the lifetime of Win2k3) so i think
it would still be worth knowing how to program the right way in ASP 3.
So here are my questions
- How do you design multi-tier web applications? What needs to go in the
Data/Business/Presentation layer? Otherwise (if 3 tier is overkill for you,
as it would be for the stuff i write) how do you architect your application?
Where do you put code, ect...?
- How do you access the db? Do you have customized classes for accessing the
data, retrieving recordsets?
- Do you have any datagrid class for displaying/editing/sorting data?
- Do you store db connections as an application variable?
- Some links to useful components (preferably free!)
- Any else?
Thank You very much for paying attention to this post.

In my previous post i forgot and important subject: error handling,
especially form processing error handling, user input validation, etc...

NEVER!

I do as much validation as I can on the client side. This way, the user
gets feedback right away, instead of waiting for a round-trip to the server.
Also, this means less toll on your web server, particularly if your user
base consists of a large ratio of numbskulls (or if your forms aren''t
designed very well :-).
However, I think it is important to also validate on the server side (for
format issues, in ASP; for data violations, in SQL Server). There should
never be a way for bad data to get into the system, and a cunning user can
usually find a way to bypass client-side validation.
