错误 R10（启动超时）-> Web 进程在启动后 60 秒内无法绑定到 $PORT - HEROKU 错误

Question

我将我的 Node.js WebApp 部署到 heroku，但出现此错误

我在此处附上我的 app.js

require("dotenv").config();
const express = require("express");
const app = express();
const ejs = require("ejs");
const mongoose = require("mongoose");
const session = require("express-session");
const passport = require("passport");
const passportLocalMongoose = require("passport-local-mongoose");
const GoogleStrategy = require("passport-google-oauth20").Strategy;
const findOrCreate = require("mongoose-findorcreate");
const timestamp = require("mongoose-timestamp");
const MongoStore = require('connect-mongo');

const auth = require("./routes/auth");
const User = require("./database/models/user_model");

const blogRoute = require("./routes/blogRoute");


mongoose.connect(process.env.DB_URI, {
  useNewUrlParser: true,
  useUnifiedTopology: true,
});
mongoose.set("useCreateIndex", true);
mongoose.set("useFindAndModify", false);

app.use(express.static("public"));
app.set("view engine", "ejs");
app.use(express.urlencoded({ extended: true }));
app.use(express.json());



app.use(session({
  secret: "foo",
  saveUninitialized: false,
  resave: false,
  store: MongoStore.create({
    mongoUrl: process.env.DB_URI,
    mongoOptions: { useUnifiedTopology: true },
    collectionName: 'sessions',
    autoRemove: 'native',
  })
}));

app.use(passport.initialize());
app.use(passport.session());

passport.use(User.createStrategy());

passport.serializeUser(function (user, done) {
  done(null, user.id);
});

passport.deserializeUser(function (id, done) {
  User.findById(id, function (err, user) {
    done(err, user);
  });
});

passport.use(
  new GoogleStrategy(
    {
      clientID: process.env.GOOGLE_CLIENT_ID,
      clientSecret: process.env.GOOGLE_CLIENT_SECRET,
      callbackURL: "http://localhost:3001/auth/google/positate" || "https://positate.herokuapp.com/auth/google/positate",
    },
    function (accessToken, refreshToken, profile, cb) {
      User.findOrCreate(
        {
          googleId: profile.id,
          name: profile.displayName,
          username: profile.emails[0].value,
          image: profile.photos[0].value,
        },
        function (err, user) {
          return cb(err, user);
        }
      );
    }
  )
);

app.get("/", (req, res) => {
  res.render("Landing");
});

app.use("/", auth);
app.use("/blog", blogRoute);
app.use("/", blogRoute);
app.use("/category", blogRoute);


app.listen(3001 || process.env.PORT, '0.0.0.0', () => {
  console.log("Server is running.");
});

这是我的 Procfile

web: node app.js

这是我的package.json

{
  "name": "positate",
  "version": "1.0.0",
  "description": "",
  "main": "app.js",
  "engines": {
    "node": "14.15.4",

    "passport-local": "^1.0.0",
    "passport-local-mongoose": "^6.1.0"
  }
}

我针对此错误尝试了多种解决方案，但无法解决。在过去的三天里，我一直在努力解决这个问题。请帮我解决这个错误非常感谢您。

Answer 1

从您的 package.json 中移除引擎并再次尝试运行。似乎存在与此相关的问题

Answer 2

问题在于您定义端口的方式，它始终在 3001 上运行，这在 Heroku 上是不可能的，您需要绑定 $PORT env 变量。
更改您的代码以首先检查是否定义了 process.env.PORT（它将在 Heroku 上，但在您的本地开发环境中它将默认为 3001）

app.listen(process.env.PORT || 3001, '0.0.0.0', () => {
  console.log("Server is running.");
});

见NodeJS on Heroku

Answer 3

我遇到了同样的问题，这让我很生气。

解决方法是将我的网络服务器配置为执行以下两者：

自动从 process.env.PORT 获取端口（也称为 $PORT 环境变量。Heroku 在部署时自动设置它。）
在地址 0.0.0.0 上明确监听（locahost 无效！）

原来 Heroku 已经在他们的 help guide 中对此进行了解释：

In rarer cases, your app may be using process.env.PORT, but may still be failing to bind. This can be caused by the app attempting to bind on localhost. Instead, you may need to change this to 0.0.0.0.
