Javascript req.session.passport为空:req.user未定义
我以前也问过类似的问题,但我注意到它在Javascript部分。 对于现在可能出现的问题,我也有更具体的想法 基本上,req.session.passport在我的日志中是空的。每当我开始在我的站点上导航时,req.user就会变得未定义,因为会话中不再有Passport的登录用户 我想知道是否有人知道如何解决这个问题?也许这只是Passport配置中的一个错误,或者整个Express设置中的一个错误 App.js:Javascript req.session.passport为空:req.user未定义,javascript,node.js,session,cookies,express,Javascript,Node.js,Session,Cookies,Express,我以前也问过类似的问题,但我注意到它在Javascript部分。 对于现在可能出现的问题,我也有更具体的想法 基本上,req.session.passport在我的日志中是空的。每当我开始在我的站点上导航时,req.user就会变得未定义,因为会话中不再有Passport的登录用户 我想知道是否有人知道如何解决这个问题?也许这只是Passport配置中的一个错误,或者整个Express设置中的一个错误 App.js: var express = require("express"), b

路线:
api.post("/signup", passport.authenticate("signup", {
successRedirect: "/profile",
failureRedirect: "/",
failureFlash: true
}))
api.post("/login", passport.authenticate("login", {
successRedirect: "/profile",
failureRedirect: "/login"//,
failureFlash: true
}))
router.get("/", function(req, res) {
// serve index.html
res.render("index", {
title: 'Home',
user: req.user,
message: req.flash("message")
})
})
它在登录后直接访问的页面上工作,我对该页面的控制如下:
router.get("/profile", isLoggedIn, function(req, res) {
res.render("profile", {
title: 'Gebruikersprofiel van ' + req.user.firstname + " " + req.user.lastname,
user: req.user // get the user out of session and pass to template
})
})
function isLoggedIn(req, res, next) {
console.log(req.session)
// if user is authenticated in the session, carry on
if (req.isAuthenticated())
return next()
// if they aren't redirect them to the home page
res.redirect("/login")
}
到目前为止,我已经尝试添加中间件将req.user添加到req.session,并在登录帖子中做了同样的事情。此外,我还尝试更改在app.js中初始化中间件的顺序。我正在使用新的express会话版本,没有CookieParser,因为我读到不再需要CookieParser
如果有人能以任何方式帮助我,我将不胜感激!和其他人一样,我也被困了一段时间。问题不在于我在设置会话或Passport时做错了什么,而在于我的链接。 我在某个地方读到有人无意中在多个域中工作,他的平台显然是多服务器的,这让我今天早上查看了我的链接 显然,我是用www.前缀链接到我的网站的,但是会话是在URL前面没有www.的地方初始化的。我在饼干里看到了这个。
因此,解决方案是通过网站进行一致的链接,无论是在哪里都加上www.前缀。问题不在于我在设置会话或Passport时做错了什么,而在于我的链接。 我在某个地方读到有人无意中在多个域中工作,他的平台显然是多服务器的,这让我今天早上查看了我的链接 显然,我是用www.前缀链接到我的网站的,但是会话是在URL前面没有www.的地方初始化的。我在饼干里看到了这个。
