|
|
* Cookie parser:
|
|
*
|
|
* Parse _Cookie_ header and populate `req.cookies`
|
|
* with an object keyed by the cookie names. Optionally
|
|
* you may enabled signed cookie support by passing
|
|
* a `secret` string, which assigns `req.secret` so
|
|
* it may be used by other middleware.
|
|
*
|
|
* Examples:
|
|
*
|
|
* connect()
|
|
* .use(connect.cookieParser('optional secret string'))
|
|
* .use(function(req, res, next){
|
|
* res.end(JSON.stringify(req.cookies));
|
|
* })
|
|
*
|
|
* @param {String} secret
