Javascript Passport js跨域登录？

用户如何从另一个域登录。主站点有登录表单，ajax发布到我的nodejs服务器上的路由

// submit form to node server(app) FROM WEBSITE
$('#submit-project-form').submit(function(e){
    e.preventDefault();

    var formData = $(this).serialize();

    $.ajax({
        url: "http://localhost:3100/login",
        data: formData,
        type: "POST",
        crossDomain: true,
        dataType: "json",
        success: function(response){
            console.log(response.responseText);
        },
        error: function(response) {
            var success =  $($.parseHTML(response.responseText)).filter("body"); 
            console.log(response.responseText);
        }
     }); 

});

// Passport POST auth methods. Listen to POST route from website
app.post('/login', passport.authenticate('local-login', {
    successRedirect : '/', // re-run user.index which should pass as a user and render profile
    failureRedirect : '/login', // redirect back to the signup page if there is an error
    failureFlash : true
}));

这将触发路由，我将获得登录passport策略所需的电子邮件和密码

passport.use('local-login', new LocalStrategy({
    usernameField : 'email',
    passwordField : 'password',
    passReqToCallback : true // allows us to pass back the entire request to the callback
},
function(req, email, password, done) { // callback with email and password from our form
    console.log(req.body.email); // returns email entered in cross-domain field
    console.log(email); // returns email entered in cross-domain field
    // find a user whose email is the same as the forms email
    // we are checking to see if the user trying to login already exists
    AppUser.findOne({ 'local.email' :  email }, function(err, user) {
        // if there are any errors, return the error before anything else
        if (err)
            return done(err);

        // if no user is found, return the message
        if (!user)
            return done(null, false, req.flash('loginMessage', 'No user found.')); // req.flash is the way to set flashdata using connect-flash

        // if the user is found but the password is wrong
        if (!user.validPassword(password))
            return done(null, false, req.flash('loginMessage', 'Oops! Wrong password.')); // create the loginMessage and save it to session as flashdata

        // all is well, return successful user
        return done(null, user); 

    });

}));

CORS是在nodejs服务器上启用的，因为我能够跨域提交支付，并且从服务器得到响应，所以它可以工作

我认为问题在于passport有

成功重定向

，问题就出在哪里，我可能需要一个自定义成功功能？有什么想法吗？

似乎是将

xhrFields

添加到ajax中使其工作。我将继续测试，但我能够用跨域帖子登录，非常酷

xhrFields: {
  withCredentials: true
},
