我收到此错误“ TypeError：JwtStrategy需要密钥或密钥”，我不知道如何解决它。我该怎么解决？

我尝试过的

为变量选择重命名
已选中，因此变量的名称相同
使用dotenv尝试
用字符串替换keys.secretOrKey

passport.js

const JwtStrategy = require('passport-jwt').Strategy;
const ExtractJwt = require('passport-jwt').ExtractJwt;
const mongoose = require('mongoose');
const User = mongoose.model("users");
const keys = require("./keys")

const opts = {};

opts.jwtFromRequest = ExtractJwt.fromAuthHeaderAsBearerToken();
opts.secretKey = keys.secretOrKey;

module.exports = passport => {
    passport.use(
        new JwtStrategy(opts, (jwt_payload, done) => {
            User.findById(jwt_payload.id)
            .then(user => {
                if (user) {
                    return done(null, user)
                }
                return done(null, false)
            })
            .catch(err => {
                console.log(err)
            });
        })
    )
}

keys.js

module.exports = {
    secretOrKey: 'secret'
};

Answer 1

您必须在选项中为密钥使用正确的密钥名称。您应该这样写：-

beginTransaction

由于错误，您编写了opts.secretKey。希望这会有所帮助！

Answer 2

1.你也可以安装mongoDB：

https://docs.mongodb.com/manual/tutorial/install-mongodb-on-ubuntu/

2.在 keys 文件中：

module.exports = {
  mongoURI: process.env.MONGO_URI,
  jwt: process.env.JWT
}

3.安装和配置服务器后，使用终端/命令行附加键值。就我而言，它是：

export NODE_ENV=production
export JWT=jwt-prod
export MONGO_URI=mongodb://localhost/db

为什么我会收到错误消息JwtStrategy需要密码或密钥？
