我无法获得增量用户ID

Question

devs我是JavaScript的新手，获取增量用户ID时遇到问题。请帮助我。

我将返回一个已解析的Promise数组，但是用户ID无法自动递增；它在复制自己。

所有用户的模型

export default [];

管理员模型

import hasher from '../helpers/password';
import CONFIG from '../config/config'
import tokenMan from '../helpers/tokenMan';

const id = 1 ; 
const is_admin = true;
const is_buyer = false;
const is_seller = false;
const email = 'john@gmail.com';
const token = tokenMan.tokenizer({id ,is_admin, is_seller, is_buyer}); 

module.exports = {
    async makeAdmin(){
        const hash= await hasher.hashingPassword(CONFIG.adminPwd, 10); 
           const admin = {
                token: token,
                id: id, 
                first_name: 'john', 
                last_name: 'doe', 
                email: email,
                address: 'Lagos',
                password: hash, 
                is_admin: is_admin,
                is_seller: is_seller, 
                is_buyer: is_buyer
            }
        return admin;
    }
}

用于注册和登录的用户控制器

import users from '../models/userModel';
import  admin from '../models/adminModel';

const User = {

    // User Sign Up
    async userSignUp(req, res) {
        const {
            error
        } = signUpFields(req.body);

        if (error) return res.status(400).json({
            status: 400,
            error: error.details[0].message
        });

        const id = users.length +1;
        const is_admin = false;
        const {
            first_name,
            last_name,
            email,
            password,
            address, 
            is_seller, 
            is_buyer
        } = req.body

        const hashed_password = await hasher.hashingPassword(password, 10);

        try {

            const newUser =  {
            token: tokenMan.tokenizer({id, is_admin, is_seller, is_buyer}),
            id: id,
            email: email,
            first_name: first_name,
            last_name: last_name,
            password: hashed_password,
            address: address,
            is_admin: is_admin,
            is_buyer: Boolean(is_buyer == "true"),
            is_seller: Boolean(is_seller == "true"),
        }

            users.push(await admin.makeAdmin(), newUser);
            Promise.all(users).then(values =>{
            return res.status(201).json({
                status: 201,
                message: 'Successfully Signed Up',
                data: values
            })
            }).catch(err =>{
                throw err.message;
            }); 

        } catch (err) {
            return res.status(500).json({
                status: 500, 
                error: err.message
            })
        }
    }
}

返回的回复正文

[ { 
    id: 1,
    first_name: 'john',
    last_name: 'doe',
    email: 'john@gmail.com',
...
  { 
    id: 1,
    email: 'yachim@gmail.com',
    first_name: 'yachim',
    last_name: 'zed',

我想获得一个适当的增量用户ID。预先谢谢你。
