【问题标题】：Heroku Node.js Error "Error MongoNetworkError", "Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch"Heroku Node.js 错误“错误 MongoNetworkError”、“错误 R10（启动超时）-> Web 进程未能在启动后 60 秒内绑定到 $PORT”

【问题描述】：

我是 nodeJS 的新手，

我想将 Heroku 上的后端上传到前端，但出现此错误

此代码在本地主机中工作， 我在 Heroku 中添加了 NODE_DATABASE

"Error MongoNetworkError", "Error R10 (Boot timeout) -> Web 进程在启动后 60 秒内未能绑定到 $PORT"

我的 app.js

const dotenv = require("dotenv").load();
const express = require("express");
const session = require("express-session");
const mongoose = require("mongoose");
const bodyParser = require("body-parser");
const passport = require("passport");
const morgan = require("morgan");
const cors = require("cors");
const LocalStrategy = require("passport-local").Strategy;
const routes = require("./routes");
const User = require("./models/User");

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

const PORT = process.env.PORT || 9000;

const app = express();
app.use(bodyParser.json());
app.use(morgan("combined"));
app.use(cors());
passport.use(new LocalStrategy(User.authenticate()));
passport.serializeUser(User.serializeUser());
passport.deserializeUser(User.deserializeUser());

app.use(
  session({
    secret: "Norbert",
    resave: false,
    saveUninitialized: true,
    cookie: { maxAge: 86400000 },
    store: new MongoStore({
      mongooseConnection: mongoose.connection,
    }),
  })
);
app.use(express.urlencoded({ extended: true }));
app.use(passport.initialize());
app.use(passport.session());

mongoose.connect(process.env.NODE_DATABASE, { useNewUrlParser: true });

const conn = mongoose.connection;
conn.on("error", console.error.bind(console, "connection error:"));
conn.once("open", () => {
  console.log("Connected to mlab database!");
  app.listen(PORT, () => console.log(`App is listening on port ${PORT}!`));
  app.use("/api", routes);
});

【问题讨论】：

  • 您的问题是连接到 mongoDB。失败会导致您的应用程序无法运行app.listen(PORT)，从而导致启动超时错误。你的$NODE_DATABASE 是什么样的？如果它只是cluster0-shard-00-00.ho4na.mongodb.net:27017，那么它正在尝试建立连接，但它缺少凭据。
  • 我的 $NODE_DATABASE "mongodb+srv://admin:@cluster0.ho4na.mongodb.net/test"

标签： node.js mongodb heroku


【解决方案1】：

好的，我找到解决方法

应用程序无法与 mongodb 连接， 解决方法是在mongodb的白名单上添加0.0.0.0/0 ip
