Node.JS Passport 未保持登录状态

Question

大家。我一直遇到这个问题，当我登录时，我无法登录。是的，我有快速 session 模块，并且设置没有错误。当我尝试做一些需要您登录而我应该已经登录的事情时，它只会将我带到登录页面(我已经对此进行了编程)。非常感谢您的所有帮助。抱歉，如果这是一个愚蠢的问题(我认为不是)。再次感谢您。

Answer 1

您需要更新两件事:

1-考虑在 Passport 初始化之前添加 session 中间件

2-您需要设置 session cookie的maxAge

所以替换这部分:

app.use(passport.initialize());
app.use(passport.session());
passport.use(new pL(User.authenticate()));
passport.serializeUser(User.serializeUser());
passport.deserializeUser(User.deserializeUser());
app.use(require("express-session")({
    secret: "Rusty is the best and cutest dog in the world",
    resave: false,
    saveUninitialized: false
}));

与:

app.use(require("express-session")({
    secret: "Rusty is the best and cutest dog in the world",
    resave: false,
    saveUninitialized: false,
    cookie: {
        secure: false,
        maxAge: 3600000 //1 hour
    }
}));

app.use(passport.initialize());
app.use(passport.session());
passport.use(new pL(User.authenticate()));
passport.serializeUser(User.serializeUser());
passport.deserializeUser(User.deserializeUser());
