ForbidenError:无效的CSRF令牌,快速js
我试着让csurf起作用,但似乎偶然发现了什么。到目前为止,代码如下所示:
index.ejs
<form method="post" action="/">
<input type="hidden" name="_csrf" value="{{csrfToken}}">
.
.
</form>
在表单中插入密码和用户名的位置。
app.js
var express = require('express');
var helmet = require('helmet');
var csrf = require('csurf');
var path = require('path');
var favicon = require('serve-favicon');
var flash = require('connect-flash');
var logger = require('morgan');
var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var session = require('express-session');
var routes = require('./routes/index');
var users = require('./routes/users');
var profile = require('./routes/profile');
var app = express();
// view engine setup
app.set('views', path.join(__dirname, 'views'));
app.set('view engine', 'ejs');
// uncomment after placing your favicon in /public
//app.use(favicon(path.join(__dirname, 'public', 'favicon.ico')));
app.use(logger('dev'));
//Security shyts
app.use(helmet());
app.use(helmet.xssFilter({ setOnOldIE: true }));
app.use(helmet.frameguard('deny'));
app.use(helmet.hsts({maxAge: 7776000000, includeSubdomains: true}));
app.use(helmet.hidePoweredBy());
app.use(helmet.ieNoOpen());
app.use(helmet.noSniff());
app.use(helmet.noCache());
// rest of USE
app.use(logger('dev'));
app.use(bodyParser.json());
app.use(bodyParser.urlencoded({ extended: false }));
app.use(cookieParser());
app.use(session({secret: 'anystringoftext', saveUninitialized: true, resave: true, httpOnly: true, secure: true}));
app.use(csrf()); // Security, has to be after cookie and session.
app.use(flash());
app.use(express.static(path.join(__dirname, 'public')));
app.use('/', routes);
app.use('/users', users);
app.use('/profile', profile);
// catch 404 and forward to error handler
app.use(function (req, res, next) {
res.cookie('XSRF-TOKEN', req.csrfToken());
res.locals.csrftoken = req.csrfToken();
next();
})
//app.use(function(req, res, next) {
// var err = new Error('Not Found');
// err.status = 404;
// next(err);
//});
// error handlers
// development error handler
// will print stacktrace
if (app.get('env') === 'development') {
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: err
});
});
}
// production error handler
// no stacktraces leaked to user
app.use(function(err, req, res, next) {
res.status(err.status || 500);
res.render('error', {
message: err.message,
error: {}
});
});
module.exports = app;
我将CSRF放在会话和Cookie解析器之后的位置。
index.js
/* GET home page. */
router.get('/', function(req, res, next) {
res.render('index', { title: 'some title',message: '' });
});
router.post('/',function(req,res){
// Where I have a bunch of mysql queries to check passwords and usernames where as if they succeed they get:
res.redirect('profile');
// Else:
res.redirect('/');
});
提交表单后得到的结果,无论我是否输入了正确的用户名和密码,我仍然收到相同的错误:
invalid csrf token
403
ForbiddenError: invalid csrf token
我还想补充说,我已经使用Node大约2周了,所以我可能还有很多需要学习的地方。
解决方案
{{csrfToken}}
不是EJS构造,所以它根本不会展开,可能会按字面意思发送到您的服务器。
这样应该能更好地工作:
<input type="hidden" name="_csrf" value="<%= csrfToken %>">
中间件正在设置csrftoken
,小写‘t’,其中模板需要大写‘T’:
res.locals.csrftoken = req.csrfToken(); // change to `res.locals.csrfToken`
您还会生成两个不同的令牌,这可能不是您想要的。将令牌存储在变量中并重复使用:
app.use(function (req, res, next) {
var token = req.csrfToken();
res.cookie('XSRF-TOKEN', token);
res.locals.csrfToken = token;
next();
});
最后,您可能必须将中间件移到路由声明之前,否则它不会被调用:
app.use(function (req, res, next) {
var token = req.csrfToken();
res.cookie('XSRF-TOKEN', token);
res.locals.csrfToken = token;
next();
});
app.use('/', routes);
app.use('/users', users);
app.use('/profile', profile);
