github身份验证后返回令牌的最佳方法

Question

I have an angular app that is using passport-github2 and oauth2 to both authenticate and gain access to github resources. I am using nodejs, koa and passport github and my server code looks a bit like this in the callback that is called by github:

router.get('/auth/github/callback', function* (next) {
  const ctx = this;

  yield passport.authenticate('github', {
    failureRedirect: '/login'
  }, function* (err, profile, failed) {
    if(!err && profile) {
      const token = jwtHelper(profile);
      ctx.redirect(config.client.syncUrl + '?token=' + token);  

In the frontend with angular, I am going to do something like this to get the token:

const token = location.query.token

I would rather send the token in a response header but I don't know how to pull the header out in the frontend angular code.

Is it possible to work with a response header in this way?

Answer 1

From koa's documentation :

response.set(field, value)

Set response header field to value:

this.set('Cache-Control', 'no-cache');

So in your case it should be something like:

ctx.set('Token', token)
