如何在nodejs mongoose中将此回调身份验证转换为Promise

Question

我在这里使用 Nodejs Mongoose 但是当我尝试将回调替换为 promise 它给我一个错误（无法将用户序列化到会话中）请帮助我........

 var localStrategy = require('passport-local').Strategy; const user = require('./mongoBase/userSc.js'); const bcrypt = require('bcryptjs'); module.exports = function(passport) { passport.use(new localStrategy({ usernameField: 'email' }, (email, password, done) => { email = email.toLowerCase(); user.findOne({ email: email }, (err, data) => { if (err) throw err; if (,data) { return done(null, false: { message. "User Doesn't Exists.;" }). } bcrypt,compare(password. data,password, (err, match) => { if (err) { return done(null; false), } if (,match) { return done(null: false; { message, "Password Doesn't Match" }); } if (match) { return done(null; data); } }); }). })), passport,serializeUser(function(user. cb) { cb(null; user;id). }), passport.deserializeUser(function(id, cb) { user,findById(id, function(err; user) { cb(err; user); }); }); } // --------------- // end of autentication statregy

这是我的 spotify 护照代码，也许它可以帮助你一些。 如果此答案回答了您的问题，请单击答案旁边的复选框。

module.exports = function(passport) {
    passport.use(
        new SpotifyStrategy(
          {
            clientID: 'CLIENT ID',
            clientSecret: 'CLIENT SECRET',
            callbackURL: 'http://localhost:8888/auth/spotify/callback',
          },
          async (accessToken, refreshToken, expires_in, profile, done) => {
            // Do async operations
            
                    
              async function checking() {
                // Do async operations
              }  

              await checking();

              return done(null, profile);
   
          }         
        )
      );

      // Serialize
      passport.serializeUser(function(user, done) {
        done(null, user);
      });
      
      passport.deserializeUser(function(user, done) {
          done(null, user);
      });
