邮递员无法正常工作的简单删除请求

Question

使用 node.js、express、mongo db 和 mongoose 创建了一个简单的电话簿应用程序。

Get 和 Post 请求工作正常，Post 请求存储在 Mongo 数据库中。

邮递员的删除请求不起作用，邮递员收到 404 未找到状态。

我想我没有引用要正确删除的条目的 ID。

当我从我的数据库中复制我的一个条目时，这些是详细信息。

{"_id":{"$oid":"6169f8bc950d87ffe2f6f033"},"name":"nick","number":"087-26387784","__v":{"$ numberInt":"0"}}

也尝试过使用 findOneAndDelete({_id: req.params.id}) 但这也没有用。

感谢任何帮助

const express = require('express');

const router = express.Router();

const Entry = require('../models/entry');



router.get('/api/entries', (req, res, next) => {

    Entry.find({}).then(entries => {

      res.json(entries)

      console.log(entries)

    })

  }) 

// add now entry to db

router.post('/api/entries', function(req, res, next){

    Entry.create(req.body).then(function(entry){

        res.send(entry);

    }).catch(next);

});



router.delete('api/entries/:id', function(req, res, next){

    Entry.findByIdAndRemove({_id: req.params.id}).then(function(entry){}).res.send(entry);

    });

module.exports = router;




const express = require('express');
const mongoose = require('mongoose');

const password = process.argv[2]

const routes = require('./routes/api');

const app = express();
mongoose.connect(`mongodb+srv://nick:${password}@cluster0.tvs6a.mongodb.net/phoneBook?retryWrites=true&w=majority`)
.then(result => {
  console.log('connected to MongoDB')
})
.catch((error) => {
  console.log('error connecting to MongoDB:', error.message)
})
//mongoose.Promise = global.Promise;

const cors = require('cors');

app.use(express.json());
app.use(routes);
app.use(function(err, req, res, next){
  //console.log(err);
  res.status(422).send({error: err.message});

});



const PORT = 3001
app.listen(PORT, () => {
  console.log(`Server running on port ${PORT}`)
})




const mongoose = require('mongoose');

// Entry Schema
const EntrySchema = new mongoose.Schema({
    name: {
       type: String,
       required: [true, 'Name field is required']
    },
    number: {
      type: String,
      required: [true, 'Number field is required']
    }  
  })

  EntrySchema.set('toJSON', {
    transform: (Entry, returnedObject) => {
      returnedObject.id = returnedObject._id.toString()
      delete returnedObject._id
      delete returnedObject.__v
    }
  })

// Entry model
const Entry = mongoose.model('entry', EntrySchema);

module.exports = Entry;

您缺少路径开头的 /：

router.delete('/api/entries/:id', function(req, res, next) {
    /// Here --^
    Entry.findByIdAndRemove({_id: req.params.id}).then(function(entry){}).res.send(entry);
});
