我发现管理会话数据的最简单方法是令牌。
您可以轻松地为expressjs和nodejs使用“passport”。
您可以生成一个令牌，该令牌使用私钥在nodejs后端签名，并由公钥标识。这些令牌甚至可以被撤销。
它们作为web标准传递到“authorization”头中。
下面是一个用于提取和检查用户提供的生成令牌的验证示例。

module.exports.ensureAuthorized = function ensureAuthorized(req, res) {
    return new Promise((resolve) => {
        let bearerToken;
        let bearerHeader = req.headers["authorization"];
        if (typeof bearerHeader !== 'undefined') {
            let bearer = bearerHeader.split(" ");
            bearerToken = bearer[1];
            req.token = bearerToken;
            this.userPayload(req.token).then((result) => {
                if (!result) {
                    return res.status(403).json({message:"Failed to verify token supplied in authorization header", data: null});
                }else{
                    resolve(result);
                }
            });
        } else {
            return res.status(403).json({message:"Failed to supply token in authorization header.", data: null});
        }
    });
};

下面是我对尝试登录的用户的restapi调用：（它生成一个有效的令牌）

let jwt = require('jsonwebtoken');
let config = require('../../misc/config');
global.atob = require("atob");
let mongoose = require('mongoose');

exports.getLogin = function(req, res) {
    const btoaAuth = (req.headers.authorization || '').split(' ')[1] || '';
    const [username, password, rememberMe] = atob(btoaAuth).toString().split(':');
    if(username && password) {
        usersModel.findOneAndUpdate({username: username},{lastLogin: new Date(),})
            .exec(function (err, userResult) {
                if(err) return res.status(500).json({message: "Server failed search users", data: err});
                if(!userResult) return res.status(500).json({message: "Username invalid", data: err});
                userResult.verifyPassword(password, function(err, isMatch) {
                    if (err) {  return res.status(500).json({message: "Server failed to process user login", data: err});}

                    // Password did not match
                    if (!isMatch) {  return res.status(403).json({message: "Password incorrect", data: err}); }
                    // Success
                    let token = jwt.sign({_id: userResult._id,username: userResult.username, exp: rememberMe === 'true'? Math.floor(Date.now() / 1000) + (60 * 60 * 24 * 365 * 100) : Math.floor(Date.now() / 1000) + (60 * 60) }, config.jwtSecret);
                    let obj = {};
                    obj['profile'] = userResult;
                    obj['profile']['password'] = undefined;
                    obj['token'] = token;
                    return res.status(200).json({message: "Successful login", data: obj});
                });
            });
    }else{
        return res.status(400).json({message: "Username and password are required", data: req.body});
    }
};
