【问题描述】:
问题:
尝试使用express-session 在登录时设置cookie,但我认为我遗漏了一些明显的东西。登录 POST 请求的响应包括 Set-Cookie。我还将Access-Control-Allow-Origin 和Access-Control-Allow-Headers 设置为通配符,如下所示:
https://i.stack.imgur.com/XS0Zv.png
但我们看到,在浏览器存储中(尝试使用 Firefox 和 Chrome),什么都没有。 As shown here
我目前正在按如下方式设置我的快速会话(请参阅帖子末尾的完整代码。添加 sn-p 以便于阅读):
app.use(session({
genid: () => { return uuidv4(); },
store: new MongoStore({ mongooseConnection: mongoose.connection }),
secret: process.env.SESSION_SECRET,
resave: false,
saveUninitialized: true,
cookie: {
httpOnly: true,
secure: false,
sameSite: true,
}
})
);
然后在我验证用户登录后,我尝试通过以下方式设置 userId:
req.session.userId = user.id;
可能的相关信息
- 这些会话已成功存储在 Mongo 中,如您所见 here,这让我相信我至少正确地生成了会话。现在我可能完全错了……
- 我的后端正在
localhost:8000上运行,通过:app.listen(8000); - 我的客户端在
http://localhost:3000/上运行 - 尽量不要将 Apollo GraphQL 用于学习目的
到目前为止我尝试过的事情:
-
resave、saveUnitialized的不同组合。 - 删除
cookie参数。 - 停止设置用户ID
- 重启浏览器和服务器
- 查看了相关的堆栈溢出帖子
请指教!甚至关于如何调试这个或我可以查看的其他内容的想法也会非常有帮助!
