是否可能获得存储的cookie的路径？ [英] Is it possible to get a stored cookie's path?

问题描述

快速问题：可以设置Cookie有效的路径，但是也可以从Cookie（PHP中）（读取）此路径？

Quick question: One can set the path where a cookie is valid, but is it also possible to get (read) this path from the cookie (in PHP)?

否则：是否可以扩展一个cookie的时间，而不知道它是什么路径（但保持路径相同）？

Or else: is it possible to extend a cookie's time, without knowing what path it's on (but keeping the path the same)?

推荐答案

由于大多数浏览器仍然使用Netscape的规范（参见缓存版本的 http://wp.netscape.com/newsref/std/cookie_spec.html ），而不是一个在 RFC 2109 或 RFC 2965 ， Cookie 请求头字段中的列表元素将只包含名称和值对：

Since most browsers still use Netscape’s specification (see cached version of http://wp.netscape.com/newsref/std/cookie_spec.html) and not the one specified in RFC 2109 or RFC 2965, the list elements in the Cookie request header field will only consist of the name and value pair:

从HTTP服务器请求URL时，浏览器会将URL与所有Cookie匹配，如果任何匹配，所有匹配的Cookie的名称/值对将包含在HTTP请求中。以下是该行的格式：

When requesting a URL from an HTTP server, the browser will match the URL against all cookies and if any of them match, a line containing the name/value pairs of all matching cookies will be included in the HTTP request. Here is the format of that line:

Cookie: NAME1=OPAQUE_STRING1; NAME2=OPAQUE_STRING2 ...

只有较新的规格和RFC 2965）允许客户端发送请求中的路径（摘自RFC 2109）：

Only the newer specifications (RFC 2109 and RFC 2965) allow the client to send the path within the request (excerpt from RFC 2109):

标题的语法是：

The syntax for the header is:

cookie          =       "Cookie:" cookie-version
                        1*((";" | ",") cookie-value)
cookie-value    =       NAME "=" VALUE [";" path] [";" domain]
cookie-version  =       "$Version" "=" value
NAME            =       attr
VALUE           =       value
path            =       "$Path" "=" value
domain          =       "$Domain" "=" value

[...]
的值path属性必须是来自相应Set-Cookie响应头的Path属性（如果有的话）
的值。否则，
属性应从Cookie请求标头中省略。 [...]

[…] The value for the path attribute must be the value from the Path attribute, if any, of the corresponding Set-Cookie response header. Otherwise the attribute should be omitted from the Cookie request header. […]
