promise中的基本身份验证(bookshelf.js & app.use -basic-auth)

const bookshelf = require('bookshelf');
const express = require('express');
const basicAuth = require('basic-auth');

const app = express();
const db = bookshelf.knex({
  // 配置数据库连接信息
});

// 定义bookshelf模型
const User = bookshelf.Model.extend({
  tableName: 'users',
});

// 定义中间件进行身份验证
const authenticate = (req, res, next) => {
  const credentials = basicAuth(req);
  if (!credentials || !credentials.name || !credentials.pass) {
    res.status(401).send('Unauthorized');
    return;
  }
  
  // 在数据库中查找用户
  User.where({ username: credentials.name })
    .fetch()
    .then((user) => {
      if (user && user.get('password') === credentials.pass) {
        next();
      } else {
        res.status(401).send('Unauthorized');
      }
    })
    .catch((error) => {
      res.status(500).send('Internal Server Error');
    });
};

// 应用身份验证中间件
app.use(authenticate);

// 其他路由和业务逻辑
// ...

app.listen(3000, () => {
  console.log('Server started on port 3000');
});
