Facebook护照身份验证，导出passport.authenticate方法

Posted 2021-03-27

我试图通过passport-facebook验证用户，并且有一件非常奇怪的事情发生，我真的不确定。在定义我的路线时，我有这行代码

app.get('/login/facebook',
        IsAuth.facebookEnter ),

//passport.authenticate('facebook')

    app.get('/login/facebook/return', 
        IsAuth.facebookComeBack)

在我的IsAuth文件中，我有以下内容

const passport = require('passport')


const FacebookStrategy = require('../passport/facebook_passport')


module.exports = {


    facebookEnter(){
       passport.authenticate('facebook')
    },
    facebookComeBack(){
        passport.authenticate('facebook', { failureRedirect: '/login' }),
            function(req, res) {
                res.redirect('/');
            }
    }


}
and the strategy itself here

const passport = require('passport')
const User = require('../models/User')
const FacebookStrategy = require('passport-facebook')

passport.use(new FacebookStrategy({
    clientID: "ALMOST POSTED IT",
    clientSecret: "Ntest test",
    //call baack to one of our routes to valiate the auth request
    //is called when the user pressed on OK to login with facebook
    callbackURL: "http://localhost:8888/login/facebook/return"
  },
  function(accessToken, refreshToken, profile, cb) {
        console.log(profile, accessToken, refreshToken)

  }
))

问题是

为什么当我写作

app.get('/login/facebook',
        IsAuth.facebookEnter ),
it doesnt work but if i write this code

app.get('/login/facebook',
            passport.authenticate('facebook') ),

那它有效，为什么呢？我的JWT护照认证工作正常，即使使用相同的文件夹结构如何使其工作并将passport.authenticate保存在单独的文件中？

答案

我不确定..但我的工作就是这个！可能只是划分module.exports？

module.exports.fbAuth = passport.authenticate("facebook");

module.exports.fbAuthCB = function(req, res, next) {
  passport.authenticate("facebook", (err, user, info) =>
    generateTokenAndRedirect(err, user, info, req, res, next)
  )(req, res);
};

router.get("/auth/facebook", authCtrl.fbAuth);
router.get("/auth/facebook/callback", authCtrl.fbAuthCB);
