我想爲我的一個實踐項目製作一個小型認證系統。我正嘗試通過郵遞員將POST請求發送到我的快遞服務器（http://localhost:4000/api/register），並且它回覆「404找不到」我正在按照教程here。爲什麼我的Express api註冊路由不是POSTing？
這裏是我的server.js：
const newpost = require('./routes/newpost');
const getposts = require('./routes/getposts');
const express = require('express');
const bodyParser = require('body-parser');
const cors = require('cors');
const deleteposts = require('./routes/delete');
const editposts = require('./routes/editposts');
const path = require('path');
const app = express();
const webpack = require('webpack');
const webpackConfig = require('../webpack.config');
const webpackMiddleware = require('webpack-dev-middleware');
const webpackHotMiddleware = require('webpack-hot-middleware');
const passport = require('passport');
const port = 4000;
const compiler = webpack(webpackConfig);
const config = require('./config/main');
const mongoose = require('mongoose');
const authRouter = require('./routes/authrouter');
const logger = require('morgan');
// db connection
mongoose.connect(config.database);
app.use(passport.initialize());
/*
app.use(webpackMiddleware(compiler, {
noInfo: true, publicPath: webpackConfig.output.publicPath,
}));
app.use(webpackHotMiddleware(compiler, {
log: console.log,
}));
*/
app.use(cors());
// parse application/x-www-form-urlencoded
app.use(bodyParser.urlencoded({ extended: false }));
// parse application/json
app.use(bodyParser.json());
app.use(logger('dev'));
app.use('/newpost', newpost);
app.use('/posts', getposts);
app.use('/delete', deleteposts);
app.use('/edit', editposts);
//auth router to handle auth routes
authRouter(app);
/*
app.get('/*', (req, res) => {
res.sendFile(path.join(__dirname, '../public/index.html'));
}); */
app.listen(port,() => {
console.log(`Listening on port ${port}`);
});
這是我authrouter.js。這些是我輸出到我的server.js中的路線。 ：
const AuthenticationController = require('../controllers/authentication');
const express = require('express');
// const passportService = require('../config/passport');
/* eslint-disable */
const passport = require('passport');
// Middleware to require login/auth
// const requireAuth = passport.authenticate('jwt', { session: false });
const requireLogin = passport.authenticate('local', { session: false });
module.exports = function(app){
"use-strict";
// init route groups
const apiRoutes = express.Router();
const authRoutes = express.Router();
// auth routes
// set auth routes as subgroup/middleware to apiRoutes
apiRoutes.use('/auth', authRoutes);
// Registration routes
authRoutes.post('/register', AuthenticationController.register);
// Login route
authRoutes.post('/login', requireLogin, AuthenticationController.login);
// Set url for API group routes
app.use('/api', apiRoutes);
};
這裏是我的authentication.js
const jwt = require('jsonwebtoken');
// const crypto = require('crypto'); used for pw resets
const User = require('../models/user');
const config = require('../config/main');
function generateToken(user) {
return jwt.sign(user, config.secret, {
expiresIn: 10080, // in seconds
});
}
// set user info from request
function setUserInfo(request) {
return {
_id: request._id,
email: request.email,
role: request.role,
};
}
// Login Route
exports.login = function (req, res, next) {
const userInfo = setUserInfo(req.user);
res.status(200).json({
token: `JWT${generateToken(userInfo)}`,
user: userinfo,
});
};
// registration route
exports.register = function (req, res, next) {
// check for registration errors
const email = req.body.email;
const password = req.body.password;
// Return error if no email provided
if (!email) {
return res.status(422).send({ error: 'You must enter an email address' });
}
// Return error if no pw provided
if (!password) {
return res.status(422).send({ error: 'You must enter a password' });
}
User.findOne({ email }, (err, existingUser) => {
if (err) { return next(err); }
// if user is not unique, return error
if (existingUser) {
return res.status(422).send({ error: 'That email address is already in use' });
}
// if email is unique and pw was provided, create acct
const user = new User({
email,
password,
});
user.save((err, user) => {
if (err) { return next(err); }
// Subscribe member to Mailchimp list
// mailchimp.subscribeToNewsLetter(user.email);
// Respond with JWT if user was created
const userInfo = setUserInfo(user);
res.status(201).json({
token: `JWT ${generateToken(userInfo)}`,
user: userInfo,
});
});
});
};
// Role authorization check
exports.roleAuthorization = function (role) {
return function (req, res, next) {
const user = req.user;
User.findById(user._id, (err, foundUser) => {
if (err) {
res.status(422).json({ error: 'No user was found' });
return next(err);
}
// if user is found, check role
if (foundUser.role == role) {
return next();
}
res.status(401).json({ error: 'You are not authorized to view this content ' });
return next('Unauthorized');
});
};
};
這裏是我的passport.js：
// Importing Passport; strategies; and config
const passport = require('passport');
const User = require('../models/user');
const config = require('./main');
const JwtStrategy = require('passport-jwt').Strategy;
const ExtractJwt = require('passport-jwt').ExtractJwt;
const LocalStrategy = require('passport-local');
const localOptions = { usernameField: 'email' };
// setting up the local Strategy
const localLogin = new LocalStrategy(localOptions, ((email, password, done) => {
User.findOne({ email }, (err, user) => {
if (err) { return done(err); }
if (!user) {
return done(null, false, { error: 'Your login details could not be verified. Please try again.',
});
}
user.comparePassword(password, (err, isMatch) => {
if (err) { return done(err); }
if (!isMatch) {
return done(null, false, { error: 'Your login details could not be verified. Please try again.',
});
}
return done(null, user);
});
});
}));
const jwtOptions = {
// Telling passport to check auth headers for JWT
jwtFromRequest: ExtractJwt.fromAuthHeader(),
// Telling passport where to find the secret
secretOrKey: config.secret,
};
// setting up JWT login strategy
const jwtLogin = new JwtStrategy(jwtOptions, ((payload, done) => {
User.findById(payload._id, (err, user) => {
if (err) { return done(err, false); }
if (user) {
done(null, user);
} else {
done(null, false);
}
});
}));
// allow passport to use the strategies we defined
passport.use(jwtLogin);
passport.use(localLogin);
