在快速会话中使用csurf

Question

I'm writing a single page application with MEAN stack , and using express-session with redis for session management.

I want to use scrf token in my client's cookies.

the problem is when I add csurf middleware, it set a session with name csrfSecret in redis, but how can I send it in cookie to client?

middlewares :

 app.use(csrf({}));

 app.use(function(req, res, next) {
     res.cookie('csrf-token', req.csrfToken());
     return next();
 });

and csrf-token is sending to client but it don't do anything.and I receive 403 error from module.

thank you for any answer or idea.

If you want to create a csrf cookie in the client you have to use the following:

app.use(csrf({ cookie: true })

This will create a token in the client. If you do not pass any options to the csrf function it will use req.session . If you want to save the cookie client-side, remember that you will need to use cookie-parser module.
