Question

我是Passport，用于对ExpressJS应用程序中的用户进行身份验证。我试图将所有Facebook路由放在他们自己的模块中，因为我打算支持其他OAuth提供商。在我的启动脚本中，我已经定义了所需的FB端点：

var express = require('express');
var routes = require('./routes');
var user = require('./routes/user');
var facebook = require('./routes/facebook');
var login = require('./routes/login');
var http = require('http');
var path = require('path');

var app = express();

/* Configuration stuff here*/

// development only
if ('development' == app.get('env')) {
  app.use(express.errorHandler());
}

app.get('/login', login.index);
app.get('/auth/facebook', facebook.fb_auth);
app.get('/auth/facebook/callback', facebook.fb_callback);

正如您所看到的，我需要我的'facebook'模块，其中包含实际路线和Facebook验证回调。它看起来像这样：

var passport = require('passport')
, FacebookStrategy = require('passport-facebook').Strategy
, User = require('../services/user');

passport.use(new FacebookStrategy({
  clientID: 'myclientid',
  clientSecret: 'mysecretkey',
  callbackURL: "http://localhost:3000/auth/facebook/callback" //localhost:3000 domain is registered domain in fb
},
function(accessToken, refreshToken, profile, done) {
   console.log('verify')
  User.findOrCreate(profile, function(err, user){
      if(err) return done(err);
      done(null, user);
  });
}
));

// Redirect the user to Facebook for authentication.  When complete,
// Facebook will redirect the user back to the application at
//     /auth/facebook/callback
exports.fb_auth = function(req, res){
  passport.authenticate('facebook')
};
// Facebook will redirect the user to this URL after approval.  Finish the
// authentication process by attempting to obtain an access token.  If
// access was granted, the user will be logged in.  Otherwise,
// authentication has failed.
exports.fb_callback = function(req, res){
  console.log('callback')
  passport.authenticate('facebook', { successRedirect: '/',
    failureRedirect: '/login' });
};

我可以看到（记录到stdout）调用了fb_auth但是上面定义的验证回调函数永远不会。我忽略了什么吗？在我可以捕获的某个地方是否发生错误？

谢谢！

我在这里找到答案：Using PassportJS with Connect for NodeJS to authenticate Facebook Users

您需要显式调用'authenticate'函数并为其提供req，res和next。

  exports.fb_auth = function(req, res, next){
  passport.authenticate('facebook')(req, res, next);
  return;
};

exports.fb_callback = function(req, res, next){
  passport.authenticate('facebook', { successRedirect: '/',
    failureRedirect: '/login' })(req, res, next);
};

使用Passport和ExpressJS进行Facebook身份验证 - 为什么不调用验证回调？
