javascript - 如何使用已有的 bcrypt 代码实施护照？

问题描述

你不会相信我，在尝试使用我已经拥有的 bcrypt 代码实现护照时，我尝试了很多事情，今天将近 15 个小时，阅读文档并尝试不同的事情，基本上我在折磨自己。

请任何人查看我的项目和我将在此处发布的几个代码，但请帮助我，我很想将护照与我拥有的 bcrypt 代码结合起来，我知道一些代码将被删除并添加一些这是正常的法律，但请任何人 HEEEELP 代码会让您深入了解事物的外观，但请花点时间在我的 GitHub 上查看我的项目 THAAANKS <3

function getErrorMessage(req) {
    let message = req.flash("error");
    if (message.length > 0) {
        message = message[0];
    } else {
        message = null;
    }
    return message;
}


exports.getLoginPage = (req, res) => {
    res.render("blog/login", {
        pageTitle: "login",
        path: "/login",
        errorMessage: getErrorMessage(req)

            res.redirect("/login");
        }
        const correctCredentials = await bcrypt.compare(password, user.password)

        if (!correctCredentials) {

        req.session.isLoggedIn = true;
        req.session.user = user;
        const result = await req.session.save(err => {
            if (err) throw err;
            res.redirect("/");
        });


    } catch (err) {
        console.log(err);

用户模型

const mongoose = require("mongoose"),
Schema = mongoose.Schema,
bcrypt = require("bcryptjs");


const userSchema = new Schema({
username: {
    type: String,
    required: true,
},

password: {
    type: String,
    required: true
}
});


userSchema.pre("save", async function save(next) {
const user = this;
if (!user.isModified("password")) return next();
const hashedPassword = await bcrypt.hash(user.password, 10);
user.password = hashedPassword;
next();
});



module.exports = mongoose.model("User", userSchema);

应用程序.js

require('dotenv').config({path: "node.env"});
const path = require('path');
const express = require('express');

const bodyParser = require('body-parser');
const mongoose = require('mongoose');
const flash = require("connect-flash");

const session = require("express-session");
const MongoDBStore = require("connect-mongodb-session")(session);
const errorController = require('./controllers/error');

const mongodb_uri = process.env.MONGODB_URI;
const app = express();
const csrf = require("csurf");
const User = require("./models/user");

const store = new MongoDBStore({
    uri: mongodb_uri,
    collection: "sessions"
});


const csrfProtection = csrf();


app.set('view engine', 'ejs');
app.set('views', 'views');


const adminRoutes = require("./routes/admin");
const blogRoutes = require("./routes/blog");
const authRoutes = require("./routes/auth");


app.use(bodyParser.urlencoded({
    extended: false
}));


app.use(express.static(path.join(__dirname, 'public')));


app.use(
    session({
        secret: process.env.SECRET,
        cookie: {
            maxAge: 1000 * 60 * 60 * 24 * 7
        },
        store: store,
        resave: false,
        saveUninitialized: false,

    })
);


app.use(flash());
app.use(csrfProtection);


app.use((req, res, next) => {
    if (!req.session.user) {
        return next();
    }
    User.findById(req.session.user._id)
    .then(user => {
        if (!user) {
            return next();
        }
        req.user = user;
        next();
    })
    .catch(err => console.log(err));
});


app.use((req, res, next) => {
    res.locals.isAuthenticated = req.session.isLoggedIn;
    res.locals.csrfToken = req.csrfToken();
    next();
});


app.use(adminRoutes);
app.use(blogRoutes);
app.use(authRoutes);


app.use(errorController.get404);


mongoose.set('useCreateIndex', true);


mongoose.connect(mongodb_uri, {
    useNewUrlParser: true
});


app.listen(3000, function () {
    console.log("listening to port 3000")
})

解决方案

在将用户插入数据库之前，您需要对密码进行哈希处理。postSignup你可以在你的函数中做这样的事情：

 exports.postSignup = (req, res, next) => {

    const {
        username,
        password
    } = req.body;

    User.findOne({
        username
    }, (err, userExists) => {
        if (err) return next(err);
        if (userExists) {
            req.flash("error", "Email exists already, please pick a different one.");

            return res.redirect("/signup");
        }

        bcrypt.hash(password, 10).then((hashed) =>{
           const user = {
              username,
              hashed 
          };

          User.insert(user);
        });
    });
};

然后当用户登录时，您需要将散列密码与用户键入的密码进行比较。但我看到你已经在用const correctCredentials = await bcrypt.compare(password, user.password).
