錯誤500上MySQL PUT和刪除通過Express，Axios

我剛剛繼承了一個項目，有點隨意使用我不是很熟悉的工具建立。它使用Express，Bookshelf和Axios來訪問MySQL數據庫。 GET和PUT的快速路由似乎工作得很好，但POST和DELETE每個導致錯誤500.錯誤500上MySQL PUT和刪除通過Express，Axios

這裏是我使用的路由（我已經刪除了更多的GET和POST路由，）：

import express from 'express'; 
import Points from '../models/points'; 

let router = express.Router(); 

// GET all points associated with a specific user AND a specific session 
// This works fine. 
router.get('/user/:user/session/:session', (req, res) => { 
    Points.query({ 
     select: ['id', 'number', 'quadrant', 'level', 'title', 'category'], 
     where: {sessionId: req.params.session, userId: req.params.user} 
    }).fetchAll().then(point => { 
     res.json({point}); 
    }) 
}); 

// POST a single point to the database. 
// This works fine. 
router.post('/', (req, res) => { 
    const {sessionId, userId, number, quadrant, level, title, category} = req.body; 

    Points.forge({ 
     sessionId, userId, number, quadrant, level, title, category 
    }).save() 
     .then(user => res.json({success: true})) 
     .catch(err => res.status(500).json({error: err})); 
}); 

// PUT (update) an existing point 
// Doesn't work right now (500) 
router.put('/edit/:identifier', (req, res) => { 
    Points.update({ 
     set: {title: req.params.title}, 
     where: {id: req.params.identifier} 
    }), function (err, point) { 
     if (err) { 
      return res.send(err); 
     } 
     res.json({message: 'Updated'}); 
    }; 
}); 

// DELETE a point by id 
// Doesn't work right now (500) 
router.delete('/delete/:identifier', (req, res) => { 
    Points.remove({ 
     id: req.params.identifier 
    }), function (err, point) { 
     if (err) { 
      return res.send(err); 
     } else { 
      res.json({message: 'Deleted'}); 
     } 
    }; 
}); 

export default router;

這裏是對應於上述的路由的終極版操作：

import axios from 'axios'; 


export function getPointsByUserAndSession(data) { 
    return dispatch => { 
     return axios.get('/api/points/user/'+data.user+'/session/'+data.session) 
    } 
} 

export function addPoint(data) { 
    return dispatch => { 
     return axios.post('/api/points', data) 
    } 
} 

export function editPointById(data) { 
    return dispatch => { 
     return axios.put('/api/points/edit/' + data.id) 
    } 
} 

export function deletePointById(identifier) { 
    return dispatch => { 
     return axios.delete('/api/points/delete/' + identifier) 
    } 
}

啓用用下面的代碼CORS：

router.use((req, res, next) => { 
    res.header('Access-Control-Allow-Origin', '*'); 
    res.header('Access-Control-Allow-Headers', 'Origin, X-Requested-With, Content-Type, Accept, x-access-token'); 
    res.header('Access-Control-Allow-Methods', 'GET, POST,OPTIONS, DELETE, PATCH, PUT'); 
    next(); 
});
