嗨，我在发出 POST 请求时遇到错误

Question

我正在使用 Nodejs、MongoDB 和 Mongoose，并且在发出 POST 请求时出现错误： POST http://localhost:3000/subscribers 内容类型：应用程序/json { “名称”：“幸运”， "subscribedToChannel": "开发技术" }

错误：{ "message": "订阅者验证失败：名称：路径 name 是必需的。subscribedToChannel：路径 subscribedToChannel 是必需的。" } 代码sn-p如下：

---

server.js

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

mongoose.connect(mongodb://localhost/subscribers, { useNewUrlParser: true })
const db = mongoose.connection
db.on('error', (error) => console.error(error))
db.once('open', () => console.log('Connected to Database'))


app.use(express.json())
const subscribersRouter = require('./routes/subscribers')
app.use('/subscribers', subscribersRouter)

app.listen(3000, () => console.log('Server Started'))```
---------------------------------------------------------------------------------------------------
routers/subscribers.js

const express = require('express')
const router = express.Router()
const Subscriber = require('../models/subscriber')

// Creating one
router.post('/', async (req, res) => {
  const subscriber = new Subscriber({
    name: req.body.name,
    subscribedToChannel: req.body.subscribedToChannel
  })
  try {
    const newSubscriber = await subscriber.save()
    res.status(201).json(newSubscriber)
  } catch (err) {
    res.status(400).json({ message: err.message })
  }
})


module.exports = router
----------------------------------------------------------------------------------------------------
models/subscriber.js

const mongoose = require('mongoose')

const subscriberSchema = new mongoose.Schema({
  name: {
    type: String,
    required: true
  },
  subscribedToChannel: {
    type: String,
    required: true
  },
  subscribeDate: {
    type: Date,
    required: true,
    default: Date.now
  }
})

module.exports = mongoose.model('Subscriber', subscriberSchema)

Answer 1

在app.use(express.json())上面使用bodyParser

喜欢：app.use(bodyparser.urlencoded({extended : false }))
