本文介绍了ForbidenError：无效的CSRF令牌，快速js的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

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);
/
