如何检测cookie是否已启用？ [英] How to detect if cookies are enabled?

问题描述

我在网上到处搜索，但找不到一个简单的例子

检测是否启用了cookie - 在服务器端，并且没有移动

从一个页面到另一个页面。

这应该是一个非常基本的功能，所以我不愿意相信

那里没有简单地在服务器端脚本中测试它的方法。

任何人？


Thx，

Agoston

Hi,
I searched around everywhere on the net, but could not find a simple example
of detecting if cookies are enabled - on server side, and without moving
from one page to another.
This should be a very basic functionality, so I am reluctant to believe that
there''s no way to simply test it in a server-side script.
Anyone?

Thx,
Agoston

推荐答案

AFAIK no。你必须测试这个客户端（它可能在同一页面上

，具体取决于客户端方法究竟是什么惹恼你）。

AFAIK no. You have to test this client side (it could be on the same page
depending on what exactly annoys you with client side methods).

" ...检测是否启用了cookie - 在服务器端......


您是否询问如何检测客户端cookie是否通过

服务器端ASP启用？

" Response.Cookies"被定义为包含所有

值的集合将在当前响应中发送回客户端的cookie。


" Request.Cookies时"定义为从用户系统发送的所有

cookie的值及其请求的集合。


因此，我认为这样可行：


Response.Cookies（" aCookie"）=" Hello World"

Response.Write"是客户端的已启用Cookie？ = &安培; （不是

IsEmpty（Request.Cookies（aCookie）））


但它返回True即使Cookies已被禁用。

"... detecting if cookies are enabled - on server side ..."

Are you asking how to detect if client-side cookies are enabled via
server-side ASP?
"Response.Cookies" is defined as "A collection containing the values of all
the cookies that will be sent back to the client in the current response.".

"Request.Cookies" is defined as A collection of the values of all the
cookies sent from the user''s system along with their request."

Thus, I thought that this would work:

Response.Cookies("aCookie") = "Hello World"
Response.Write "Are client-side cookies enabled? = " & (Not
IsEmpty(Request.Cookies("aCookie")))

But it returned "True" even when Cookies were disabled.

但这是一个愚蠢的期望。

Response.Write"是否启用了客户端Cookie？ = &安培; （不是
IsEmpty（Request.Cookies（aCookie）））

detecting if cookies are enabled - on server side,
and without moving from one page to another.
But that is a silly expectation.

Response.Cookies("aCookie") = "Hello World"
Response.Write "Are client-side cookies enabled? = " & (Not
IsEmpty(Request.Cookies("aCookie")))

But it returned "True" even when Cookies were disabled.

您如何在不联系客户的情况下期望服务器了解客户端，

？


你将不得不求助于这样的事情：


1.asp：


<％

Response.Cookies（" aCookie"）=" Hello World"

Response.redirect" 2.asp"

％> ;


2.asp：


<％

如果会话（aCookie）=" ; Hello World然后

Response.Write" Cookies Enabled"

Else

Response.Write" Cookies disabled"

结束如果

How do you expect the server knowing anything about the client,
without contacting the client?

You will have to resort to something like this:

1.asp:

<%
Response.Cookies("aCookie") = "Hello World"
Response.redirect "2.asp"
%>

2.asp:

<%
If Session("aCookie") = "Hello World" Then
Response.Write "Cookies Enabled"
Else
Response.Write "Cookies Disabled"
End If
%>
