会话变量问题 [英] Session variables problem

问题描述

我遇到了正确构建以下问题的方法（使用c＃

asp.net）： -


我的问题是如何最好从一个网页传递收集的数据

用于另一个网页。


我的问题是如何最好地从第一页传递搜索条件

到第二个。搜索条件作为结构存在，并在用户按下第一页上的搜索按钮时填写。


1.呈现收集用户搜索条件的asp页面

2.查询SQL后显示搜索结果网格


如果我使用会话来存储它，那么这会导致会话中的问题

变量会在用户的第二次搜索时被覆盖，但是在浏览器的后退按钮上按几下b / b
会让您进入预期的页面

会话中不同的标准从早些时候开始不再存在。


ViewState似乎不好，因为它只能用于回发和上面的问题

仍然会导致问题。


我不想在地址行中传递搜索条件，因为这是

凌乱并允许用户更改和查看它。


我相信你也可以使用Server.Transfer但我认为这会有一个

长期可用数据的类似问题。


任何关于正确方法的指示都是最受欢迎的。

I am having issues with the right way to architecture the following (using c#
asp.net):-

The question I have is how best pass the collected data from one web page
for use in another.

The question I have is how best pass the search criteria from the first page
to the second. The search criteria exists as a structure and is filled when
the user presses the ''Search'' button on the first page.

1. Present an asp page for collecting user search criteria
2. Show grid with results of search after querying SQL

If I use the session to store it, then this causes problems as the session
variable is overwritten on a second search by the user, but a couple of
presses on the back button of the browser will get you to a page expecting
different criteria in the session from earlier which is no longer there.

ViewState seems no good as it only works on postback and the above issue
would still cause a problem.

I do not want to pass the search criteria in the address line as this is
messy and allows the user to change and view it.

I beleive you can also use Server.Transfer but I think this would have a
similiar issue with the data being available long-term.

Any pointers as to the correct approach to this would be most welcome.

推荐答案

这样的页面的一个好方法是使用查询字符串。那个

方式的数据全部都包含在URL中，用户可以将这些数据加入书签

。这个URL确实有尺寸限制（2048

个字符，我想？）

您可以使用的替代架构之一考虑是 - 暴露公共[共享]道具在第一页（搜索按钮所在的位置）上进行操作，然后从第二页进行调用。在ASP.NET中，每个与类关联的表单都可以从任何其他类调用。这样我们就不必像使用asp应用程序那样使用查询字符串。


看一下这个链接 - http://authors.aspalliance.com/aspxt...weenpages.aspx

这种方法有问题：当你想回到搜索页面时你从第二页到第一页的标准是什么？实现此目的的一种方法是 - 在第二页上公开公共[共享]属性，并从第一页调用它们。


微软也有关于此的文档，但我发现它找不到方便。希望这有帮助。

One of the alternative architechture you can consider is - exposing public [shared] properties on the First page (where the search button located) and call them from the second page. In ASP.NET every form assocaited with a class and it can be called from any other classes. This way we don''t have to use query string like we had to use in asp applications.

Take a look at this link - http://authors.aspalliance.com/aspxt...weenpages.aspx

Problem with this approach: when you want to come back to search page what criteria do you bring back from second page to first page? One way to accomplish this is - exposing public [shared] properties on second page and call them from the first page.

Microsoft also has documentation on this but I could not find it find handy. Hope this help.

感谢您的支持快速回复斯科特。我希望避免使用URL查询

字符串，以免将其暴露给用户。我认为我的问题来自于

C ++ / C＃背景我还没有完全失去这种无状态方法！


Scott Allen写道：

Thanks for the quick reply scott. I was hoping to avoid using the URL query
string so as not to expose it to the user. I think my problem is coming from
a C++/C# background I haven''t fully grapsed this stateless approach as yet !
