Question

我正在尝试创建一个将通过使用类与Postgres数据库进行交互的类，但是在类中创建函数时会不断出错

我尝试将构造函数与原型一起使用，但仍然出现错误

/* eslint linebreak-style: ["error", "windows"] */
// eslint-disable-next-line no-unused-vars
const pool = require('../config/config.js');
// user constructor
class User {
  constructor(user) {
    this.username = user.username;
    this.email = user.email;
    this.password = user.password;
    this.role = user.role;
  }
  // save new user in databes
  function createUser() {

  }

  }

module.exports = User;




function createUser(params) {
           ^^^^^^^^^^

SyntaxError: Unexpected identifier
    at new Script (vm.js:80:7)
    at createScript (vm.js:274:10)

    at Module.require (internal/modules/cjs/loader.js:637:17)
    at require (internal/modules/cjs/helpers.js:22:18)

这是正在得到的错误

Answer 1

const pool = require('../config/config.js');
// user constructor
class User {
  constructor(user) {
    this.username = user.username;
    this.email = user.email;
    this.password = user.password;
    this.role = user.role;
  }
  // save new user in database
  createUser() {

  }

  }

module.exports = User;

正如其他人所提到的，这仅仅是一个语法问题。
