参数化passport社交登录回调

Question

对于facebook和linkedin的回调，我有以下回调：

router.get('/auth/linkedin/callback', social.linkedin().authenticate('linkedin', {failureRedirect: '/web/login'}), function(req, res, next) { res.redirect(req.session.redirectURL); });
router.get('/auth/facebook/callback', social.facebook().authenticate('facebook', {failureRedirect: '/web/login'}), function(req, res, next) { res.redirect(req.session.redirectURL); });

我如何对它们进行参数化，这样我就可以去掉一个线性函数，比如

// somehow get a service from the wildcard in the uri    
router.get('/auth/*/callback', social.service().authenticate(service, {failureRedirect: '/web/login'}), function(req, res, next) { res.redirect(req.session.redirectURL); });

Answer 1

试试这个

router.get('/auth/:service/callback', function (req, res, next) {
    social[req.params.service]().authenticate(req.params.service, {failureRedirect : '/web/login'})(req, res, next);
}, function (req, res, next) {
    res.redirect(req.session.redirectURL);
});
