passportjs facebook传递回叫请求

Question

我必须在这里忽略一些东西.我正在使用visajs的Facebook策略来验证用户.这是通过2个请求/ [路由处理程序]完成的:

//one to initiate the the auth:
init: function (req, res, next) {
    passport.authenticate('facebook', {
        callbackURL: URL + '/facebook/callback',
        state: req.body //attempting to put some state
    })(req, res, next)
}

//one callback
callback: function (req, res, next) {
    passport.authenticate('facebook', {
        callbackURL: URL + '/facebook/callback'
    },
    function (err, profile, accessToken, refreshToken) {
        if (err) return next(err)
        res.send(passedReqBody)
    })(req, res, next)
}

//the verify callback doesn't do much.
//Application logic is done in route callback handlers
passport.use(new FacebookStrategy({
    clientID: config.facebook.id,
    clientSecret: config.facebook.secret
},
//When setting passReqToCallback to true, it is set as the first argument
//to the verify callback. As in:
//function (req, accessToken, refreshToken, params, profile, done) {
//But this is the 'callback' request object. I want the 'init' request object.
function (accessToken, refreshToken, params, profile, done) {
    //params.state is undefined
    return done(null, profile, accessToken, refreshToken);
}));

我的问题是我希望第一个函数的POST请求体在回调路由处理程序中公开.

OAuth2Strategy构造函数'passReqToCallback'有一个选项可以将最新请求发送回验证回调,这对我没用(我想要第一个request.body)

下一个看似合理的道路是使用'state'选项,如https://github.com/jaredhanson/passport-oauth/blob/master/lib/passport-oauth/strategies/oauth2.js #L169

但是这些值在getOAuthAccessToken回调中不可用https://github.com/jaredhanson/passport-oauth/blob/master/lib/passport-oauth/strategies/oauth2.js#L124

我当前的选择是在OAuth2Strategy.prototype.authenticate()函数中添加一个额外的变量,它在第一个函数上设置,并且传回,不变,回调函数,但我无法想象这是通往走.

根据您的描述,最佳方法可能取决于您的应用程序,但这里是您init和callback中间件的快速修改:

init: function (req, res, next) {
    // SAVE BODY IN SESSION
    req.session.initBody = req.body;

    passport.authenticate('facebook', {
        callbackURL: URL + '/facebook/callback',
        state: req.body //attempting to put some state
    })(req, res, next)
}

//one callback
callback: function (req, res, next) {
    passport.authenticate('facebook', {
        callbackURL: URL + '/facebook/callback'
    },
    function (err, profile, accessToken, refreshToken) {
        if (err) return next(err)
        // RESTORE BODY FROM SESSION
        res.send(req.session.initBody);
        delete req.session.initBody;
    })(req, res, next)
}

请注意,原始请求正文将持久保存到会话中,然后在回调时恢复.如果您希望数据在请求/响应周期中存活,这是一种技术.但是,我要注意,GET回调中的变异状态可能并不可取,因此如果根据原始主体修改任何内容,请务必小心.
