当使用Request.Cookies时过Response.Cookies？ [英] When to use Request.Cookies over Response.Cookies?

问题描述

难道我用的响应时，在页面的事件（例如负载），因为这是从ASP.NET的响应，并请求时pressing一个按钮，因为这是一个反应将ASP.NET处理？还是有更多的吗？

Do I use response when at a page event (e.g. load) as this is a response from ASP.NET, and request when pressing a button as this is a response going to ASP.NET for processing? Or is there more to it?

推荐答案

它们是两种不同的东西，一个的保存 [回应]，其他的为 [请求]

They are 2 different things, one SAVES [Response], the other READS [Request]

在一个Cookie（信息学说）:)
您保存一个小文件的一段包含类型的对象时间 字符串

in a Cookie (informatics speaking) :) you save a small file for a period of time that contains an object of the type string

在.NET框架您保存一个cookie 做：

HttpCookie myCookie = new HttpCookie("MyTestCookie");
DateTime now = DateTime.Now;

// Set the cookie value.
myCookie.Value = now.ToString();
// Set the cookie expiration date.
myCookie.Expires = now.AddMinutes(1);

// Add the cookie.
Response.Cookies.Add(myCookie);

Response.Write("<p> The cookie has been written.");

您写一个Cookie，将可一分钟...通常我们做的 now.AddMonth（1）的，所以你可以保存一个cookie一整个月。

You wrote a cookie that will be available for one minute... normally we do now.AddMonth(1) so you can save a cookie for one entire month.

要取回cookie的，则使用Request（你是请求），如：

To retrieve a cookie, you use the Request (you are Requesting), like:

HttpCookie myCookie = new HttpCookie("MyTestCookie");
myCookie = Request.Cookies["MyTestCookie"];

// Read the cookie information and display it.
if (myCookie != null)
   Response.Write("<p>"+ myCookie.Name + "<p>"+ myCookie.Value);
else
   Response.Write("not found");

记住：

要删除一个Cookie，没有直接code，关键是为保存相同Cookie名称与已经通过，例如到期日期， now.AddMinutes （-1）

To Delete a Cookie, there is no direct code, the trick is to Save the same Cookie Name with an Expiration date that already passed, for example, now.AddMinutes(-1)

这将删除cookie。

this will delete the cookie.

正如你可以看到，每一个cookie的生命时间到期时，该文件从系统自动删除的时间。

As you can see, every time that the time of life of the cookie expires, that file is deleted from the system automatically.
