如何保护express.js中的路由?
How to protect routes in express.js?
例如,在 Meteor 中,有类似
的内容
Router.plugin('ensureSignedIn');
Router.plugin('ensureSignedIn', {
except: ['home', 'atSignIn', 'atSignUp', 'atForgotPassword']
});
因此未签名的用户无法访问除以上四种之外的其他路由。
如何在 express.js 中执行此操作?我也在用 passport.js。
我对 Meteor 不熟悉,但是你可以做类似下面的事情,假设你想让页面只对经过身份验证的用户(护照)可用。
function ensureAuthenticated(req, res, next) {
if (req.isAuthenticated())
return next();
else
// Return error content: res.jsonp(...) or redirect: res.redirect('/login')
}
app.get('/account', ensureAuthenticated, function(req, res) {
// Do something with user via req.user
});
ensureAuthenticated
函数只是一个例子,您可以定义自己的函数。调用 next()
继续请求链。
我应该使用中间件来保护我的路由,甚至保护同一路由中的某些动词:
例如:在my endpoint/route.js
// the require sentences are omitted
const express = require('express');
const { /*controllerFunctions*/ } = require('./controller');
const {routeGuard} = require('/*must create a route guard*/');
const router = express.Router();
router.route('')
.get(getAllResources)
;
router.route('/:id') //
.get(validateParam,getOneResource);
router.use(routeGuard);
router.route('/:id')
.post(validateParam,validateBody,postResource)
.patch(validateParam,validateBody,patchProblemById)
.delete(validateParam,deleteResource)
;
module.exports = router;
我的 routeGuard
文件应该是这样的:
const { promisify } = require('util');
const jwt = require("jsonwebtoken");
const AppError = require('./appError');
const {User} = require('./../endpoints/users/model');
const wrapper = require('./try-wrapper');//try catch wrapper
module.exports.routeGuard = wrapper(async function (req, res, next){
// the err message is the same on purpose
const notAllowed = new AppError('Unauthorized: Invalid or Nonexistent credentials',401);
let token = null;
if (req.headers.authorization && req.headers.authorization.startsWith('Bearer')){
token = req.headers.authorization.split(' ')[1];
}
if (!token) return next(notAllowed );
const payload = await promisify(jwt.verify)(token,process.env.KEY);
const user = await User.findById(payload.id);
if (!user) return next( notAllowed);
if ( ! user.hasSamePasswordSince(payload.iat) )return next( notAllowed );
req.user = user; // further use...
next();
});
