node.js - 覆盖/更新浏览器 cookie

Question

我有一个 Express 4.x 应用程序，我将一个 cookie 传递给浏览器

res.cookie('foo','bar1', {maxAge:99999999999});

它在遥远的 future 到期。然而，5 分钟后，我收到同一用户的另一个请求，我想给他们一个新的 cookie。

 res.cookie('foo','bar2', {maxAge:99999999999});

从我的调试来看，新的 cookie 似乎没有覆盖旧的 cookie？是这样吗？ 如何用新的 cookie 更新/覆盖旧的 cookie？

Answer 1

我大约 99% 确定使用 {overwrite: true} 属性可以解决问题 - 从这里开始:

https://www.npmjs.com/package/cookies

它说:

cookies.set( name, [ value ], [ options ] ) This sets the given cookie in the response and returns the current context to allow chaining.

If the value is omitted, an outbound header with an expired date is used to delete the cookie.

If the options object is provided, it will be used to generate the outbound cookie header as follows:

maxAge: a number representing the milliseconds from Date.now() for expiry expires: a Date object indicating the cookie's expiration date (expires at the end of session by default). ... overwrite: a boolean indicating whether to overwrite previously set cookies of the same name (false by default). If this is true, all cookies set during the same request with the same name (regardless of path or domain) are filtered out of the Set-Cookie header when setting this cookie.

那么，用 Node.js Express 的说法就是:

res.cookie('cdt_app_token', encoded, {maxAge: 90000000, httpOnly: true, secure: false, overwrite: true});

请注意，如果您使用的是非 SSL 或非 TLS 连接，如果 secure 为 true，cookie 可能无法工作。
