使用Vue CLI在Node js上执行Express Session

Question

我正在为使用Vue开发的应用程序编写nodejs后端应用程序。我需要为用户的数据库操作创建会话，并根据用户选择数据库。我想使用express会话，但我创建的会话在不同的请求中被视为未定义的。我该如何克服这个问题？我在Vue上使用历史模式，所以我的请求现在必须通过路由器。我还可以表示，我对其他建议持开放态度。

const express = require('express')
const app = express()
const productRequest = require("./controllers/products/products")
const customerRequest = require("./controllers/customers/customers")
const orderRequest = require("./controllers/orders/orders")
const controllerRequest = require("./controllers/controllers")
const swaggerUi = require('swagger-ui-express');
const swaggerDocument = require('./swagger.json');
var session = require('express-session')
const cors = require("cors")
app.set('trust proxy', 1) // trust first proxy
app.use(session({
secret: 'keyboard cat',
resave: false,
saveUninitialized: true,
cookie: { secure: true }
}))
app.use(express.json());
app.use(cors());
app.use('/api-docs', swaggerUi.serve, swaggerUi.setup(swaggerDocument));
app.use('/products', productRequest)
app.use('/orders', orderRequest)
app.use('/customers', customerRequest)
app.use('/controllers', controllerRequest)
module.exports = app;

const express = require('express');
const controllers = express.Router();
const login = require('./login.js')
const userkey = require("./userkey");
controllers.post("/login", (req, res, next) => {
login(req.body, response => {
if (response[0].total == 0) {
res.status(204).json({
message: "Fail",
result: null
})
} else if (response[0].total == 1) {
/* SESSION SETTED HERE  */
req.session.corp = response[0].corp
console.log(req.session.corp)
/* HERE SEEMS CREATED */
res.status(200).json({
message: "Connected",
result: response
})
}
})
});
controllers.post("/userkey", (req, res, next) => {
/* CANT USE HERE response UNDEFINED*/
console.log(req.session.corp)
userkey([req.body, req.session.corp], response => {
res.status(200).json({
data: response
})
})
});
module.exports = controllers;

我在会话中遇到了一些严重的头痛，我会一直坚持到阅读

然后请考虑使用JWT

就这么简单：

var jwt = require('jsonwebtoken');
var token = jwt.sign({ foo: 'bar' }, 'shhhhh');

jsonwebtoken包使用简单，应该符合您的需求。
