Node.JS Express Route 导致 404 Only For a specific Route

如何解决Node.JS Express Route 导致 404 Only For a specific Route

我的 node.js 快速路由有问题。我真的很新，看不到我的错误。我也在 Stackoverflow 上阅读了类似的线程，但仍然没有设法解决这个问题。也许有人可以帮助发现错误。

我创建了 4 条路由：home-routes.js、user-routes、tech-routes.js 和 user-auth.js。向 http://localhost:8001/api/auth 或 http://localhost:8001/api/auth/

发送请求时，只有 user-auth.js 路由会不断收到 404 错误

这是我的server.js

const mongoose = require('mongoose');
mongoose.set('useNewUrlParser',true);
mongoose.set('useFindAndModify',false);
mongoose.set('useCreateIndex',true);
mongoose.set('useUnifiedTopology',true);

const express = require('express');
const router = express.Router();

const { func } = require('joi');
const Joi = require('joi');
const helmet = require('helmet')
const morgan = require('morgan')
const config = require('config');
const debug = require('debug')('app:startup');


const home_routes = require('./api/routes/home-routes');
const technology_routes = require('./api/routes/tech-routes');
const user_routes = require('./api/routes/user-routes');
const user_auth = require('./api/routes/user-auth');

// ======================================
//              APP-CONFIG
// ======================================
const app = express();
const port = process.env.PORT || 8001;
const connection_url = `mongodb+srv://${username}:${password}@cluster0.zmc6p.mongodb.net/upss-db?retryWrites=true&w=majority`


// ======================================
//              DB CONFIG
// ======================================
mongoose.connect(connection_url)
    .then(() => console.log('Connected to MongoDB...'))
    .catch(err => console.error('Could not connect to MongoDB...',err));

// ======================================
//              MIDDLE-WARES
// ======================================

app.use(express.json());
app.use(express.urlencoded({ extended: true })); //parse url key=value to json
app.use(express.static('public')); //static assets inside folder 'public'
app.use(helmet());


// ======================================
//         API-ENDPOINTS-PREFIX
// ======================================
app.use('/',home_routes);
app.use('/api/tech',technology_routes);
app.use('/api/user',user_routes);
app.use('./api/auth',user_auth);

//Capture All 404 errors
app.use(function (req,res,next) {
    res.status(404).send('Unable to find the requested resource!');
});


// ======================================
//              LISTENERS
// ======================================

app.listen(port,() => console.log(`Listening on localhost Port ${port}...`));

这是user-auth.js

const mongoose = require('mongoose');
const express = require('express');
const router = express.Router();
const _ = require('lodash');
const bcrypt = require('bcrypt');

const { User } = require('../models/user-schema');


router.get('/',(req,res) => {
    res.status(200).send("GET ALL TECHS");
});


// ======================================
//              POST REQUEST
// ======================================

/* CREATE ONE NEW USER */

router.post('/',async (req,res) => {
    const { error } = validateEmailPassword(req.body);
    if (error) return res.status(400).send(error.details[0].message);

    // The user with this email is not found in the DB
    let user = await User.findOne({ email: req.body.email });
    if (!user) return res.status(400).send('Invalid email or password!');

    // Password does not match with our DB
    const validPassword = await bcrypt.compare(req.body.password,user.password);
    if (!validPassword) return res.status(400).send('Invalid email or password!');

    res.send(true);

});


function validateEmailPassword(req) {
    const validationSchema = Joi.object({
        email: Joi.string().min(5).max(255).required().email(),password: Joi.string().min(5).max(255).required()
    });
    return validationSchema.validate(req);
}

module.exports = router;

另一个类似于 user-routes.js 中的路由工作正常。

const mongoose = require('mongoose');
const express = require('express');
const router = express.Router();
const _ = require('lodash');
const bcrypt = require('bcrypt');

const { User,validateUser } = require('../models/user-schema');


router.get('/',res) => {
    res.status(200).send("GET ALL USERS");
});



/* CREATE ONE NEW USER */

router.post('/',res) => {
    const { error } = validateUser(req.body);
    if (error) return res.status(400).send(error.details[0].message);

    // Make sure the user not already registered
    let user = await User.findOne({ email: req.body.email });
    if (user) return res.status(400).send('User already registered!');
    user = new User(_.pick(req.body,['firstName','lastName','email','password']));
    const salt = await bcrypt.genSalt(10);
    user.password = await bcrypt.hash(user.password,salt);
    await user.save();


    res.send(_.pick(user,['_id','firstName','email']));

});



module.exports = router;

解决方法

也许你想要

app.use('/api/auth',user_auth);

不是

app.use('./api/auth',user_auth);

在您的 server.js 文件中，因为它似乎是一个错字问题。
