uniapp中连接数据库问题

教程中的代码

//获取数据库内容
router.get('/api/goods/search', function(req,res,next){
    
        
        
        connection.query("select * from goods_search", function (error, results, fields) {
          if (error) throw error;
          console.log('The solution is: ', results);
        });

        
        
    
});

无法连接，需要优化，正常的代码

router.get('/api/goods/search', function (req, res, next) {
  connection.query('SELECT * FROM goods_search', function (error, results, fields) {
    if (error) {
      console.error('Error executing query:', error);
      return res.status(500).json({ error: 'Database error' });
    }

    console.log('The solution is: ', results);

    // 发送响应
    res.json({
      message: 'Query successful',
      data: results,
    });
  });
});

输出数据

router.get('/api/goods/search', async function (req, res, next) {
  let result = await connection.query('SELECT * FROM goods_search');
  res.json({
    message: 'Query successful',
    data: result,
  });
});
