node.js – passport：登录和帐户注册的不同重定向

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,以便我可以在护照身份验证完成后相应地重定向(“/ welcome”或“/ back_again”).

我的应用程序中的其他护照代码：

// 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' }),res) {
    res.redirect('/');
  });

解决方法

在你的验证回调中,我会改变一些事情,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',{ failureRedirect: '/login' }),res) {
    // successful auth,user is set at req.user.  redirect as necessary.
    if (req.user.isNew) { return res.redirect('/back_again'); }
    res.redirect('/welcome');
  });
