我的 API 在 express + mariadb 中的方法不起作用

Question

我在 MariaDB 和 ExpressJS 中有一个 API，并且可以正常工作获取路由...

const getAllBills = async (req, res) => {
    try {
      const conn = await pool.getConnection();
      const result = await conn.query('SELECT * FROM facturas')
      res.status(200).json(result);
    } catch (err) {
      res.status(500).json({
        message: err.message
      });
    }
  };

const createBills = async (req, res) => {
    try {
      const conn = await pool.getConnection();
      const result = await conn.query(
      'INSERT INTO facturas (total, nombre, apellido, ciudad, direccion, codigo_postal, cedula) VALUES (?, ?, ?, ?, ?, ?, ?)', 
      [req.body.total, req.body.nombre, req.body.apellido, req.body.ciudad, req.body.direccion, req.body.codigo_postal, req.body.cedula]
    );
    
    const deleteBills = async (req, res) => {
    try {
      const conn = await pool.getConnection();
      const result = await conn.query('DELETE FROM facturas WHERE id = ?', [req.params.id]);
      if (result.affectedRows === 0) {
        res.status(404).json({
          message: 'Factura no encontrada'
        });
      } else {
        res.status(200).json(result);
      }
    } catch (err) {
      res.status(500).json({
        message: err.message,
      });
    }
  }

这些是我的路线，除了 post 和 delete

之外都有效

const { Router } = require('express');
const router = Router();

const { getAllBills, getBillsByCedula, createBills, deleteBills } = require('../controllers/facturaControllers');

router.get('/facturas', getAllBills);

router.post('/facturas', createBills);

router.delete('/facturas/:id' , deleteBills);

然后，我不知道该怎么办，因为服务器确实可以正常工作，但是当我发出 POST 或 DELETE 请求时，我收到错误 500。

此代码缺少}符号，creatbills的function/logic和controller中的delete bill必须分开

尝试使用此代码：

const createBills = async (req, res) => {
    try {
      const conn = await pool.getConnection();
      const result = await conn.query(
      'INSERT INTO facturas (total, nombre, apellido, ciudad, direccion, codigo_postal, cedula) VALUES (?, ?, ?, ?, ?, ?, ?)', 
      [req.body.total, req.body.nombre, req.body.apellido, req.body.ciudad, req.body.direccion, req.body.codigo_postal, req.body.cedula]
    );
    } catch (err){
        res.status(500).json({
            message: err.message,
          });
    };
};
    
const deleteBills = async (req, res) => {
    try {
      const conn = await pool.getConnection();
      const result = await conn.query('DELETE FROM facturas WHERE id = ?', [req.params.id]);
      if (result.affectedRows === 0) {
        res.status(404).json({
          message: 'Factura no encontrada'
        });
      } else {
        res.status(200).json(result);
      }
    } catch (err) {
      res.status(500).json({
        message: err.message,
      });
    };
};
