我的架构未保存到我的数据库（MongoDB）

Question

我正在学习一个教程，但在一个点上卡住了。我尝试在邮递员中发出一个POST请求，但返回一个我无法解决的错误。错误如下：

（节点：3224）UnhandledPromiseRejectionWarning：MongooseError：操作users.insertone()缓冲在10000ms超时后超时。(C:\users\murad\desktop\full stack\node\node_modules\mongoose\lib\drivers\node-MongoDB-native\collection.js:185:20)在listOnTimeout（内部/timers.js:549:17)在processstimers（内部/timers.js:492:7)（使用node--trace-warnings...来显示警告是在哪里创建的）（节点：3224）unhandledpromiseerejectionwarning：未处理的承诺拒绝。这个错误可能是由于抛出一个没有catch块的异步函数内部，或者是由于拒绝了一个未用.catch（）处理的承诺。要在未处理的承诺拒绝时终止节点进程，请使用CLI标志--unhandled-rejections=strict（请参见https://nodejs.org/api/CLI.html#CLI_unhandled_rejections_mode)。（拒绝ID：1）（节点：3224）[DEP0018]拒绝警告：拒绝未处理的承诺。将来，未处理的承诺拒绝将以非零退出代码终止node.js进程。

代码在下面

// index.js File
const express = require('express');
const app = express();
const mongoose = require('mongoose');
// const dotenv = require('dotenv');

// Import Routes
const authRoute = require('./routes/auth');

// Route middleware
app.use(express.json());
app.use('/api/user', authRoute);

// dotenv.config();
const myUrl = 'mongodb+srv://murad:<password>@cluster0.ag5vr.mongodb.net/DatabaseName?retryWrites=true&w=majority';

mongoose.connect(myUrl,
    { useNewUrlParser: true, useUnifiedTopology: true },
    () => {
        console.log('Connected to db');
    })



app.listen(3000, () => console.log('Server up and running'));

// My auth.js (router) file
const router = require('express').Router();
const User = require('../model/User');

router.post('/register', async (req, res) => {
    const user = new User({
        name: req.body.name,
        email: req.body.email,
        password: req.body.password
    })
    
        const savedUser = await user.save();
        res.send(savedUser);
    
})

module.exports = router;

// And my User.js (model) file
````const mongoose = require('mongoose');

const userSchema = mongoose.Schema({
    name: {
        type: String,
        required: true,
        min: 6,
        max: 255
    },
    email: {
        type: String,
        required: true,
        min: 6,
        max: 255
    },
    password: {
        type: String,
        required: true,
        min: 6,
        max: 1024
    },
    date: {
        type: Date,
        default: Date.now
    }
})

module.exports = mongoose.model('User', userSchema);

I tried to look up solutions but none seemed to work. Help would be much appreciated! Thanks in advance

Answer 1

router.post('/register', async (req, res) => {
const user = new User({
    name: req.body.name,
    email: req.body.email,
    password: req.body.password
})
    const savedUser = await user.save().catch( e => { console.error(e) 
    res.send(savedUser);

});

尝试使用catch捕获错误
