在HTTP规范中，分隔cookie的字符串是什么？ [英] In HTTP specification, what is the string that separates cookies?

问题描述

分号; ， Cookie：字符串或其他字符串？

Semicolon ;, the Cookie: string or some other string?

推荐答案

检查HTTP请求中的cookie

Cookie： header具有以下语法：

Inspecting cookies in an HTTP request

The Cookie: header has the following syntax:

Cookie: <Name> = <Value> { ; <Name> = <Value> }

因此，用分号分隔各个cookie。

Hence individual cookies are separated with the semicolon.

另一方面，在响应中设置cookie时，每个 Set有一个cookie -Cookie： header：

On the other hand, when setting a cookie in the response, there one cookie per the Set-Cookie: header:

Set-Cookie: <Name> = <Value> [ ; expires = <Date>] [ ; path = <Path> ] [ ; domain = <Domain> ] // etc…

设置多个cookie Set-Cookie 标头在HTTP响应中重复。

To set multiple cookies the Set-Cookie header is repeated in an HTTP response.

注意：

• 查看此处示例教程，以及 RFC 6265 HTTP状态管理机制 规范性参考，显示语法的全部细节。


• 现已过时的 RFC 2965 定义了另一对标题 Cookie2 和 Set-Cookie2 ，这些标题已被放弃。


• HTTP状态管理机制的已废弃版本（ RFC 2109 和 RFC 2965 ）提供了折叠多种方式将 Set-Cookie （或 Set-Cookie2 ）标题合并为一个。但是，最新的 RFC 6265 规范不建议进行此折叠。

• Have a look here for a tutorial with examples, and to RFC 6265 HTTP State Management Mechanism for a normative reference showing the full details of the syntax.
• The now-obsolete RFC 2965 defined an alternate pair of headers Cookie2 and Set-Cookie2 which were abandoned.
• The obsoleted versions of the HTTP State Management Mechanism (RFC 2109 and RFC 2965) provided a way to fold multiple Set-Cookie (or Set-Cookie2) headers into one. However, this folding is not recommended by the latest RFC 6265 spec.
