req.isAuthenticated（）在passportjs中始终返回false

Question

我在express和req.isAuthenticated（）中设置了护照，由于index.js中的代码顺序错误，总是返回。我无法弄清楚我必须编写代码的顺序，我在stackoverflow中搜索了其他答案，由于我的代码具有不同的依赖关系，所以我找不到正确的顺序，请帮忙。这是我的index.js文件：

const winston = require("winston");
const express = require("express");
const config = require("config");
const app = express();
const passport = require('passport');
const flash    = require('connect-flash');
var session = require('express-session');
const cookieParser = require('cookie-parser');
app.use(express.json());
app.use(cookieParser());








app.use(session({ 
  secret: 'ilovescotchscotchyscotchscotch',
  resave: false,
  saveUninitialized: true,
  cookie: { secure: true }
}));
app.use(passport.initialize());
app.use(passport.session());

require('./services/passport')(passport);

require("./startup/db")();


app.use(flash());



require("./startup/logging")();
require("./startup/cors")(app);
require("./startup/routes")(app);

require("./startup/config")();
//require("./startup/validation")();



const port = process.env.PORT || config.get("port");
const server = app.listen(port, () =>
  winston.info(`Listening on port ${port}...`)
);

module.exports = server;

谢谢。
