javascript - "Error: MongooseError: Operation ` users.insertOne() ` buffering timed out after 10000ms",

Question

我在 node express 上运行 MongoDB Atlas，当我使用 postman 进行测试时出现此错误。

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

require('dotenv').config();

const app = express();
const port = process.env.PORT || 5000;

app.use(cors());
app.use(express.json());

const uri = process.env.ATLAS_URI;
mongoose.connect(uri, { useNewUrlParser: true, useCreateIndex: true }
);
const connection = mongoose.connection;
connection.once('open', () => {
  console.log("MongoDB database connection established successfully");
})

const exercisesRouter = require('./routes/exercises');
const usersRouter = require('./routes/users');

app.use('/exercises', exercisesRouter);
app.use('/users', usersRouter);

app.listen(port, () => {
    console.log(`Server is running on port: ${port}`);
});

这是我的 .env ，我猜问题可能也在这里，请帮助:

ATLAS_URI=mongodb+srv://userone:useronepassword1234@cluster0.swye5.mongodb.net/<dbname>?retryWrites=true&w=majority

Answer 1

就我而言，我必须去 Atlas，并将我的白名单 IP 重置为正确的地址。
然后我重新启动了我的本地服务器并尝试再次在 postman 上发帖......它成功了!
