javascript - 用户的个人资料和封面图片在一段时间后消失了

问题描述

在本地运行时，一切都很好，但是当应用程序部署在 Heroku 上时，并且有人注册添加了个人资料图片和封面照片，一段时间后它会为所有用户删除，我不知道为什么。因为当它在本地运行时，一切都很好。您还可以检查应用程序的家伙应用程序。在这里，所以我不知道为什么我已经使用 heroku 一年多了，但这从未发生过

这是主要代码，如果您需要其他任何内容，请告诉我。

const express = require('express');
const app = express();
const port =  process.env.PORT || 3000;
const middleware = require('./middleware')
const path = require('path')
const bodyParser = require("body-parser")
const mongoose = require("./database");
const session = require("express-session");
const http = require('http');
// const server = require('./server');



const server = app.listen(port, () => console.log("Server listening on port " + port));
const io = require("socket.io")(server, { pingTimeout: 60000 });

app.set("view engine", "pug");
app.set("views", "views");

app.use(bodyParser.urlencoded({ extended: false }));
app.use(express.static(path.join(__dirname, "public")));

app.use(session({
    secret: "bbq chips",
    resave: true,
    saveUninitialized: false
}))

// Routes
const loginRoute = require('./routes/loginRoutes');
const registerRoute = require('./routes/registerRoutes');
const logoutRoute = require('./routes/logout');
const postRoute = require('./routes/postRoutes');
const profileRoute = require('./routes/profileRoutes');
const uploadRoute = require('./routes/uploadRoutes');
const searchRoute = require('./routes/searchRoutes');
const messagesRoute = require('./routes/messagesRoutes');
const notificationsRoute = require('./routes/notificationRoutes');

// Api routes
const postsApiRoute = require('./routes/api/posts');
const usersApiRoute = require('./routes/api/users');
const chatsApiRoute = require('./routes/api/chats');
const messagesApiRoute = require('./routes/api/messages');
const notificationsApiRoute = require('./routes/api/notifications');

app.use("/login", loginRoute);
app.use("/register", registerRoute);
app.use("/logout", logoutRoute);
app.use("/posts", middleware.requireLogin, postRoute);
app.use("/profile", middleware.requireLogin, profileRoute);
app.use("/uploads", uploadRoute);

app.use("/api/users", usersApiRoute);
app.use("/api/chats", chatsApiRoute);
app.use("/api/messages", messagesApiRoute);
app.use("/api/notifications", notificationsApiRoute);

app.get("/", middleware.requireLogin, (req, res, next) => {

    var payload = {
        pageTitle: "Home",
        userLoggedIn: req.session.user,
        userLoggedInJs: JSON.stringify(req.session.user),
    }

    res.status(200).render("home", payload);
})

io.on("connection", socket => {

    socket.on("setup", userData => {
        socket.join(userData._id);
        socket.emit("connected");
    })

    socket.on("join room", room => socket.join(room));
    socket.on("typing", room => socket.in(room).emit("typing"));
    socket.on("stop typing", room => socket.in(room).emit("stop typing"));
    socket.on("notification received", room => socket.in(room).emit("notification received"));

    socket.on("new message", newMessage => {
        var chat = newMessage.chat;

        if(!chat.users) return console.log("Chat.users not defined");

        chat.users.forEach(user => {
            
            if(user._id == newMessage.sender._id) return;
            socket.in(user._id).emit("message received", newMessage);
        })
    });

})

解决方案

Heroku 在一段时间不活动后进入停用模式。发生这种情况时，您的照片将被删除。你应该找另一个地方上传你的照片。
