node.js - 在node.js中使用passport.js登录Twitter不起作用

Question

我在node.js中使用passport.js进行twitter登录。但它不起作用。它会在进程中停留一段时间，然后返回，没有错误或成功。

我的代码:

module.exports.loginWithTwitter = function (req, res) {

var passport = require('passport');
var Strategy = require('strategy');
var TwitterStrategy = require('passport-twitter').Strategy;

// used to serialize the user for the session
passport.serializeUser(function (user, done) {
    done(null, user.id);
});

// used to deserialize the user
passport.deserializeUser(function (id, done) {
    User.findById(id, function (err, user) {
        done(err, user);
    });
});

passport.use(new TwitterStrategy({
    consumerKey: "HMtGdCax3EMhUAikCi2uySwoQ",
    consumerSecret: "QZlWEdjVbPkWPr7cfS6ohbZgNAkpiboRbP0HGaiv1AvTJRtATw",
    callbackURL: "http://192.168.0.102:4000/api/userData/get"
}, function (token, tokenSecret, profile, cb) {
    console.log('call');
    process.nextTick(function () {
        console.log(profile);
    });
}));
}

我没有收到“console.log('call');”打电话。

我的App.js代码

var express = require('express'),
    app = express(),
    bodyParser = require('body-parser'),
    mongoose = require('mongoose'),
    http = require('http'),
    cors = require('cors');


app.use(cors());

app.use(function(req, res, next) {
    var allowedorigins = ['http://localhost:4000'];
    var origin = req.headers.origin;
    //if (allowedorigins.indexof(origin) > -1) {
    //    res.setheader('access-control-allow-origin', origin);
    //}
    res.header("access-control-allow-credentials", "true");
    res.header("access-control-allow-headers", "x-requested-with");
    res.header("access-control-allow-headers", "origin, x-requested-with, content-type, accept,application/x-www-form-urlencoded");

    next();
});

app.get('/', function(req, res) {
    res.setHeader('Content-Type', 'application/json,application/x-www-form-urlencoded');
    res.send(JSON.stringify({
        Server: "A"
    }));
});

var passport = require('passport');
app.get('/auth/twitter', passport.authenticate('twitter'));

app.get('/auth/twitter/callback', passport.authenticate('twitter', {
    failureRedirect: '/login'
}), function(req, res) {
    console.log('callback')
        // Successful authentication, redirect home.
    res.redirect('/');
});

mongoose.Promise = global.Promise;
mongoose.connect('mongodb://localhost/Eviral'); // mongo DB Connection

var server = app.listen(4000);
var router = express.Router();
app.use(bodyParser.urlencoded({
    limit: '100mb',
    extended: true
})); // configure app to use bodyParser() this will let us get the data from a POST
app.use(bodyParser.json({
    limit: '100mb'
}));


app.use(function(req, res, next) {
    var _send = res.send;
    var sent = false;
    res.send = function(data) {
        if (sent) return;
        _send.bind(res)(data);
        sent = true;
    };
    next();
});

app.use(express.static(__dirname));
app.use(require('./routes/clientMSTRoute'));

您尚未在 app.js 中初始化 Passport。在使用其身份验证策略之前，您需要配置passport。

此外，您需要初始化express-session来为您的用户创建登录 session 。

在 app.js 中添加这些行。 Ingore 无论你已经拥有其中的一些。但是，请确保维持秩序。

app.use(express.cookieParser());
app.use(express.bodyParser());
app.use(express.session({ secret: 'your_secret_keyword' }));
//Below two lines are required to initialize passport
app.use(passport.initialize());
app.use(passport.session());//this should come after express-session  
                            //to ensure login session is restored in correct order

确保导入所有必需的 Node 模块。以下是这些所需的人员。添加 app.js

中还没有的内容

var cookieParser = require('cookie-parser');
var bodyParser = require('body-parser');
var expressSession = require('express-session');
var passport = require('passport');

请阅读passport configure documentation了解更多信息。
