'UnhandledPromiseRejectionWarning: MongoParseError: Invalid connection string‘问题正在发生，我不知道是什么问题
提问于 2020-08-05 08:21:10
homePage.create不工作。我想我的问题出在这里"mongoose.connect('mongo://localhost:27017/Socialuser', { useNewUrlParser: true, useUnifiedTopology: true });"
App.js文件
const express = require('express');
const bodyParser = require('body-parser');
const mongoose = require('mongoose');
let homePage = require('./models/home');
mongoose.connect('mongo://localhost:27017/Socialuser', { useNewUrlParser: true, useUnifiedTopology: true });
const app = express();
app.use(express.static(__dirname + '/public'));
app.get('/', (req, res) => {
res.render('landing.ejs');
});
app.get('/login', (req, res) => {
res.render('loginSignUp.ejs');
});
app.get('/home', (req, res) => {
console.log(homePage);
homePage.create({ name: 'wasim', image: 'https://www.w3schools.com/w3css/img_lights.jpg' }, (err, home) => {
if (err) {
console.log(err);
} else {
console.log('saved');
}
});
});
app.listen(3000, () => {
console.log('server started at port 3000');
});这是我的home.js文件。它是主模式文件
const mongoose = require('mongoose');
let homePageSchema = new mongoose.Schema({
name: String,
image: String
// comments: [ String ]
});
module.exports = mongoose.model('Home', homePageSchema);我不明白到底发生了什么，真正的问题是什么？'UnhandledPromiseRejectionWarning: MongoParseError: Invalid connection string‘将出现.this问题

1) Please use this
mongodb://localhost:27017/Socialuser
Instead of -
mongo://localhost:27017/Socialuser
2) mongoose.connect("mongodb://localhost:27017/[yourDbName]", {
useUnifiedTopology: true,
useNewUrlParser: true
});
In your case yourDbName = Socialuser
