Question

成功登录Facebook后，Facebook战略失败了。我使用Passport Local和Passport Facebook，但彼此独立，这里是我分享的代码。

passport.use(new FacebookStrategy({
    clientID: 'XYZId',
    clientSecret: 'XYZSecret',
    callbackURL: "/auth/facebook/callback"
  },
  function(accessToken, refreshToken, profile, done) {
      console.log(profile);
      userDetails = profile;
      return done();
  }
));

app.get('/auth/facebook', passport.authenticate('facebook'));

app.get('/auth/facebook/callback',
     passport.authenticate('facebook', {
             failureRedirect: '/login' }),
             function(req, res) {
                    console.log("req");
                    console.log(userDetails);
                    console.log("End of Req");
                    res.redirect('/');
              });

此代码有什么问题吗？此外，对于本地策略，我已经修改了一点，它工作得很好。

// config/passport.js

// load all the things we need
var LocalStrategy   = require('passport-local').Strategy;

var bcrypt = require('bcrypt-nodejs');

var connection = mysql.createConnection(dbconfig.connection);

connection.query('USE ' + dbconfig.database);

module.exports = function(passport) {

                var insertQuery = "INSERT INTO users ( uname, username, password, userphone ) values (?,?,?,?)";
                console.log(insertQuery);

您没有在会话中存储授权的Facebook用户。您只需在FacebookStrategy的实现中调用函数done()而不使用参数。首先，您应该将fb用户存储在您的数据库中，或者选择是否存在然后调用函数done（接收第一个参数作为错误，第二个作为用户对象）。 here's docs
