我是MERN堆栈的新手。我从教程中学习了使用connect-mongo的express-session,我一直得到以下错误:

**const timeoutError = new error_1.MongoServerSelectionError(Server selection timed out after ${options.serverSelectionTimeoutMS} ms, this.description);
                                 ^

字符串
我做了一些研究,它说,这可能是因为我的服务器没有运行,但当我打开“服务”,它说它了。我试图重新启动它多次,但它没有帮助。这是我的代码:

const express = require("express");
const session = require("express-session");
const mongoose = require("mongoose")
const MongoStore = require("connect-mongo");

const app = express();

app.use(express.urlencoded({extended: true}))

const connection = mongoose.createConnection("mongodb://127.0.0.1/testDB", {useNewUrlParser: true})

app.use(session({
    secret: 'keyboard cat',
    saveUninitialized: false, // don't create session until something stored
    resave: false, //don't save session if unmodified
    store: MongoStore.create({
      mongoUrl: 'mongodb://localhost/test-app',
      touchAfter: 24 * 3600 // time period in seconds
    })
  }));

app.get("/", (req,res)=>{
    res.send("...")
})

app.listen(3000, ()=>{
    console.log("server is running")
})


Thanks in advance

如果您确定mongo服务器正在运行,则您的应用无法连接到mongo服务器,在这种情况下,请检查Mongo conf文件。

Linux: /etc/mongod.conf
macOS: /usr/local/etc/mongod.conf (on Intel processors), or /opt/homebrew/etc/mongod.conf (on apple M1 processors)
Windows: <install directory>\bin\mongod.cfg

字符串
您的bindip值应该如下所示:

net:
  bindIp: 127.0.0.1, ::1
  ipv6: true
