这是我的护照代码

    const JwtStrategy= require('passport-jwt').Strategy;
    const ExtractJwt=require('passport-jwt').ExtractJwt;
    const User= require('../models/user');
    const config=require('../config/database');        
    module.exports=function(passport){
    let opts={};
    opts.jwtFromRequest=ExtractJwt.fromAuthHeader();
    opts.secretOrKey=config.secret;
    opts.issuer = 'accounts.examplesoft.com';
    opts.audience = 'yoursite.net';
    passport.use(new JwtStrategy(opts,(jwt_payload,done)=>{
        console.log(jwt_payload);
        User.getUserById(jwt_payload._doc._id,(err,user)=>{
            if(err){
                return done(err,false);
            }
            if(user){
                return done(null,user);
            }
            else{
                return done(null,false);
            }
        });
    }));
}

我的身份验证和获取配置文件代码

My code for authenticate and get profile

// Authenticate
router.post('/authenticate', (req, res, next) => {
  const username = req.body.username;
  const password = req.body.password;

  User.getUserByUsername(username, (err, user) => {
    if(err) throw err;
    if(!user){
      return res.json({success: false, msg: 'User not found'});
    }

    User.comparePassword(password, user.password, (err, isMatch) => {
      if(err) throw err;
      if(isMatch){
        const token = jwt.sign(user, config.secret, {
          expiresIn: 604800 // 1 week
        });

        res.json({
          success: true,
          token: 'JWT '+token,
          user: {
            id: user._id,
            name: user.name,
            username: user.username,
            email: user.email
          }
        });
      } else {
        return res.json({success: false, msg: 'Wrong password'});
      }
    });
  });
});

// Profile
router.get('/profile', passport.authenticate('jwt', {session:false}), (req, res, next) => {
  res.json({user: req.user});
});

推荐答案

在线失败

const token = jwt.sign(user, config.secret, {

出现错误预期有效负载"是一个普通对象"

您的 user 对象在此处初始化:

Your user object is initialized here:

User.getUserByUsername(username, (err, user)

我假设是 mongoosejs 对象，它包含许多方法并且不是可序列化的".您可以通过使用 mongoose 中的 .lean() 或普通 toJSON 方法传递一个普通对象来处理这个问题:

Which I assume is mongoosejs object, which contains many methods and is not "serializable". You could handle this by passing a plain object, by either using .lean() from mongoose or plain toJSON method:

const token = jwt.sign(user.toJSON(), config.secret, {
  expiresIn: 604800 // 1 week
});
