我在我的应用程序中使用护照模块(github身份验证),我想根据操作重定向...我检查它是否只是正常登录或用户是否第一次登录。
passport.use(new GitHubStrategy({
clientID: conf.github.app_id,
clientSecret: conf.github.app_secret,
callbackURL: conf.github.callback_url
},
function(accessToken, refreshToken, profile, done) {
// asynchronous verification, for effect...
process.nextTick(function () {
// To keep the example simple, the user's GitHub profile is returned to
// represent the logged-in user. In a typical application, you would want
// to associate the GitHub account with a user record in your database,
// and return that user instead.
Models_User.findOrCreateUser(profile, function(msg){
console.log("auth type:" + msg);
});
return done(null, profile);
});
}
));
在我的findOrCreateUser函数中,我检查它是否是新用户并执行所有数据库操作...进行测试我让函数返回一个msg变量,该变量只是一个表示“login”或“new_registration”的字符串。
所以我的问题是如何“传输”我从findOrCreateUser获得的变量,这样我可以在护照身份验证完成后相应地重定向(“/ welcome”或“/ back_again”)。
我的应用中的其他护照代码:
// GET /auth/github
// Use passport.authenticate() as route middleware to authenticate the
// request. The first step in GitHub authentication will involve redirecting
// the user to github.com. After authorization, GitHubwill redirect the user
// back to this application at /auth/github/callback
app.get('/auth/github',
passport.authenticate('github'),
//passport.authenticate('github', { scope: ['user', 'public_repo', 'gist'] }),
function(req, res){
// The request will be redirected to GitHub for authentication, so this
// function will not be called.
});
// GET /auth/github/callback
// Use passport.authenticate() as route middleware to authenticate the
// request. If authentication fails, the user will be redirected back to the
// login page. Otherwise, the primary route function function will be called,
// which, in this example, will redirect the user to the home page.
app.get('/auth/github/callback',
passport.authenticate('github', { successRedirect: '/', failureRedirect: '/login' }),
function(req, res) {
res.redirect('/');
});
答案 0 :(得分:10)
在验证回调中,我会更改内容,以便findOrCreateUser
函数将实际记录提供给回调,然后将其传递给done()
,如下所示:
Models_User.findOrCreateUser(profile, function(user){
console.log("auth type:" + msg);
return done(null, user);
});
// take this out, use the actual model above
//return done(null, profile);
现在,在验证后处理回调URL时,您可以检查此用户记录并查看它是否是新的(我假设它在这里有一个isNew属性):
app.get('/auth/github/callback',
passport.authenticate('github', { failureRedirect: '/login' }),
function(req, res) {
// successful auth, user is set at req.user. redirect as necessary.
if (req.user.isNew) { return res.redirect('/back_again'); }
res.redirect('/welcome');
});
