這是我的代碼：

檔案：

web:node server

.gitignore：

node_modules/

服務器.js

const express = require('express')
const morgan = require('morgan')
const cors = require('cors')
const connectDB = require('./config/db')
const passport = require('passport')
const bodyParser = require('body-parser')
const routes = require('./routes/index')


connectDB()

const app = express()

if(process.env.NODE_ENV === 'development') {
    app.use(morgan('dev'))
}

app.use(cors())
app.use(bodyParser.urlencoded({extended: false}))
app.use(bodyParser.json())
app.use(routes)
app.use(passport.initialize())
require('./config/passport')(passport)

const PORT = process.env.PORT || 3000

app.listen(PORT, console.log(`Server running in ${process.env.NODE_ENV} mode on port ${PORT}`))

包.json：

{
  "name": "flutterauth",
  "version": "1.0.0",
  "description": "Authentication system for flutter apps",
  "main": "server.js",
  "scripts": {
    "start": "cross-env NODE_ENV=production node server",
    "dev": "cross-env NODE_ENV=development nodemon server"
  },
  "author": "pomoworko",
  "license": "MIT",
  "dependencies": {
    "bcrypt": "^5.0.1",
    "body-parser": "^1.20.0",
    "connect-mongo": "^4.6.0",
    "cors": "^2.8.5",
    "cross-env": "^7.0.3",
    "express": "^4.18.1",
    "jwt-simple": "^0.5.6",
    "mongoose": "^6.4.4",
    "morgan": "^1.10.0",
    "nodemon": "^2.0.19",
    "passport": "^0.6.0",
    "passport-jwt": "^4.0.0"
  }
}

現在，我得到了這個：

如果我在命令提示符下寫：“heroku restart”，它可以工作

如果我在命令提示符下寫：“heroku logs --tail”，它會再次顯示給我，第一張圖片，它不起作用

如何修復此錯誤

先感謝您

我假設您正在使用 mongodB 地圖集。 您需要將您的 IP 地址列入白名單。 為此，請轉到您的network access選項卡，並包含一個 IP 地址0.0.0.0/0 。 這是一個通配符 IP 地址，它允許所有具有正確憑據的 IP 地址訪問您的數據庫。

像這樣：

注意：這會將所有 IP 地址列入白名單。 測試的時候沒問題。 但是在投入生產時，您可能只想將應該有權訪問集群的 IP 地址列入白名單……出於安全目的。
