为一条路由Passport.js多个策略。将会话仅用于一种策略

const passport = require('passport');
const LocalStrategy = require('passport-local').Strategy;
const FacebookStrategy = require('passport-facebook').Strategy;

passport.use(new LocalStrategy(
  function(username, password, done) {
    // 验证用户名和密码
    // 如果验证成功，调用done(null, user)；如果验证失败，调用done(null, false)
  }
));

passport.use(new FacebookStrategy({
    clientID: FACEBOOK_APP_ID,
    clientSecret: FACEBOOK_APP_SECRET,
    callbackURL: "http://www.example.com/auth/facebook/callback"
  },
  function(accessToken, refreshToken, profile, done) {
    // 验证用户的Facebook身份
    // 如果验证成功，调用done(null, user)；如果验证失败，调用done(null, false)
  }
));

app.post('/login', passport.authenticate(['local', 'facebook']), function(req, res) {
  // 身份验证成功后的处理逻辑
});
