Change cookie expiration in Express
提问by user1161657
Because I didn't define a maxAge when calling expressServer.use(express.session({params}))the cookie's expiration is set as "Session".
因为我在调用expressServer.use(express.session({params}))cookie 的过期时间设置为“Session”时没有定义 maxAge 。
I would like to add a "remember me" feature when logging in. If "remember me" is selected, the expiration will be extended to a month.
我想在登录时添加“记住我”功能。如果选择“记住我”，有效期将延长至一个月。
How would I go about doing this? I tried simply extending the maxAge, but that didn't seem to do anything...
我该怎么做呢？我尝试简单地扩展 maxAge，但这似乎没有任何作用......
expressServer.get '/blah', (request, response) =>
request.session.cookie.maxAge = 2592000
response.end 'hello there'
Thanks for the help!
谢谢您的帮助！

I tried making a simple server to test updating a user's cookie. I'm using Express 3.0.4
我尝试制作一个简单的服务器来测试更新用户的 cookie。我正在使用 Express 3.0.4
When I visit 127.0.0.1:9000/blah, the browser cookie's "expires" field is still "session"...
当我访问 127.0.0.1:9000/blah 时，浏览器 cookie 的“过期”字段仍然是“会话”...
express = require 'express'
expressServer = express()
expressServer.use express.cookieParser()
expressServer.use express.session
secret: 'supersecret'
cookie:
path: '/'
httpOnly: true
expressServer.get '/', (request, response) =>
response.end 'hello'
expressServer.get '/blah', (request, response) =>
request.session.cookie.maxAge = 3600000
response.end 'hello again'
expressServer.listen 9000
console.log 'server running'
Grrrrrrr....
咕噜噜....

I have a checkbox that says "remember me" on the /login page:
我在 /login 页面上有一个复选框，上面写着“记住我”：
<p class="remember">
<input type="checkbox" id="remember" name="remember" value="1" />
<label for="remember">Remember me</label>
</p>
Then in my POST route to /login I do some sanity checking and set the session if req.body.rememberis set otherwise its just a window session:
然后在我到 /login 的 POST 路由中，我进行了一些完整性检查并设置了会话，req.body.remember否则它只是一个窗口会话：
//user is authenticated
//set session length
if ( req.body.remember ) {
var hour = 3600000;
req.session.cookie.maxAge = 14 * 24 * hour; //2 weeks
} else {
req.session.cookie.expires = false;
}
req.session.userid = user._id;
Add the following few lines (I use redis) in app.js:
在 app.js 中添加以下几行（我使用 redis）：
app.use(express.cookieParser('secret-word'));
app.use(express.session({
store: new RedisStore({
host: cfg.redis.host,
db: cfg.redis.db
}),
secret: 'another-secret'
}));

If you want to implement rolling sessions with cookie-sessionsin express 4, configure the middleware like this:
如果要在 express 4 中使用cookie-sessions实现滚动会话，请像这样配置中间件：
app.use(cookieSession({
secret: your_secret,
maxAge: your_maxAge,
key: 'sessionId'
}));
Note that you do not need to set the expiresoption.
请注意，您不需要设置该expires选项。
In order to extend your session, simply alter it like this:
为了延长您的会话，只需像这样更改它：
app.get('*', function (req, res, next) {
req.session.foobar = Date.now();
next();
}
Note that in express 4 there is no req.session.touch().
请注意，在 express 4 中没有req.session.touch().

Set cookie name to value, where which may be a string or object converted to JSON. The path option defaults to "/".
将 cookie 名称设置为 value，其中可以是字符串或转换为 JSON 的对象。路径选项默认为"/".
res.cookie('rememberme', '1',
{ expires: new Date(Date.now() + 900000), httpOnly: true });

Or You can try this, it worked for me:
或者你可以试试这个，它对我有用：
if ( req.body.remember )
{
var oneWeek = 7 * 24 * 3600 * 1000; //1 weeks
req.session.cookie.expires = new Date(Date.now() + oneWeek);
req.session.cookie.maxAge = oneWeek;
}
