错误R10(启动超时)-&gt；Web进程无法在启动后60秒内绑定到$Port-Heroku错误 [英] Error R10 (Boot timeout) -> Web process failed to bind to $PORT within 60 seconds of launch - HEROKU ERROR

问题描述

我将Node.js WebApp部署到Heroku，但收到此错误

我在这里附加我的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.");
});

这是我的配置文件

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",
    "npm": "6.14.10"
  },
  "scripts": {
    "start": "node app.js"
  },
  "author": "",
  "license": "ISC",
  "dependencies": {
    "connect-mongo": "^4.4.1",
    "dotenv": "^10.0.0",
    "ejs": "^3.1.6",
    "express": "^4.17.1",
    "express-session": "^1.17.2",
    "mongoose": "^5.12.11",
    "mongoose-findorcreate": "^3.0.0",
    "mongoose-timestamp": "^0.6.0",
    "passport": "^0.4.1",
    "passport-google-oauth20": "^2.0.0",
    "passport-local": "^1.0.0",
    "passport-local-mongoose": "^6.1.0"
  }
}

我尝试了针对此错误的各种解决方案，但都无法解决。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 提前感谢您。

推荐答案

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环境变量。
更改您的代码以首先检查是否定义了process.env.PORT(它将位于Heroku上，但在您的本地开发环境中将默认为3001)

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