firebase Facebook和Twitter重新认证： [英] firebase facebook and twitter Re-authenticating:

问题描述

我已经在Facebook和Twitter的应用程序中正确设置了Firebase身份验证，但是我遇到了问题。

一旦用户连接，如果他决定注销并进入用不同的凭据他不能这样做。事实上，如果他试图用Facebook注销系统不会询问他的用户名和密码，但使用之前插入的凭据。

我试着与rememberMe选项，但它没有解决这个问题。
有人可以帮我吗？

解决方案

我严格遵循可以在这里找到的例子： https://www.firebase.com/docs/security/simple-login-overview.html

无论如何，我修改了一下，做了一些检查。
这是我使用的代码
$ b

  firebaseRef = new Firebase（'https ：//cicero.firebaseio.com'）; 
 authClient = new FirebaseAuthClient（firebaseRef，function（error，user）{
 if（error）{
 / * login error * / 
 switch（error.code）{
 case'INVALID_EMAIL'：
 case'INVALID_PASSWORD'：
 EventDispatcher.trigger（login_error，invaild user or email）; 
 break; 
 case'INVALID_USER' ：
 EventDispatcher.trigger（login_error，user does not exist。）; 
 break; 
 case'UNKNOWN_ERROR'：
 EventDispatcher.trigger（login_error，未知错误，请联系事件管理员。）; 
} 
} else if（user）{
 / * user si logga * / 
 cicero_user = user; 
 var users = new Users（）; 
 users.firebase.on（'value'，function（）{
 if（cicero_user.provider =='password'）{
 var user = users.findWhere（{id：cicero_user.id，type： '密码'}）; 
 cicero_user.displayName = user.get（'name'）; 
 alert（cicero_user.displayName）; 
} else {
 var social_user = users.findWhere（{id：cicero_user.id，type：cicero_user.provider}）; 
 if（social_user == undefined）{
 var new_social_user = new User（{id：cicero_user.id，name：cicero_user.displayName，type：cicero_user.provider}）; 
 users.add（new_social_user）; 
} 
} 
 Ciceronotifier.on（）; 
 EventDispatcher.trigger（hide_spinner）; 
 Backbone.history.navigate（map，{trigger：true}）; 
}，this）; 
} else {
 / * user si slogga * / 
 cicero_user = undefined; 
 firebaseRef.unauth（）; <  - 我现在已经添加了这两行，但问题似乎未解决
 firebaseRef =新的Firebase（'https://cicero.firebaseio.com'）; 
 Backbone.history.navigate（login，{trigger：true}）; 
  

I have properly set firebase authentication in my app for Facebook and twitter but I have a problem.

Once an user is connected, if he decides to logout and enter with a different credentials he can't do it. Indeed if he tries to logout again with Facebook the system doesn't ask his username and password but uses credentials inserted before.

I tried with rememberMe option but it didn't solve the problem. Can someone help me?

解决方案

I strictly followed the example that can be found here: https://www.firebase.com/docs/security/simple-login-overview.html

Any way i modified it a little bit for doing some check. Here is the code I'm using

firebaseRef = new Firebase('https://cicero.firebaseio.com');
        authClient = new FirebaseAuthClient(firebaseRef, function(error, user) {
            if (error) {
                /*login error*/
                switch(error.code) {
                    case 'INVALID_EMAIL':
                    case 'INVALID_PASSWORD':
                        EventDispatcher.trigger("login_error","invaild user or email");
                        break;
                    case 'INVALID_USER':
                        EventDispatcher.trigger("login_error","user does not exist.");
                        break;
                    case 'UNKNOWN_ERROR':
                        EventDispatcher.trigger("login_error","unknown error, please contact event administrator.");
                }
            } else if (user) {
                    /*user si logga*/
                    cicero_user = user;
                    var users = new Users();
                    users.firebase.on('value',function(){
                        if(cicero_user.provider == 'password'){
                            var user = users.findWhere({id: cicero_user.id, type:'password'});
                            cicero_user.displayName = user.get('name');
                            alert(cicero_user.displayName);
                        } else {
                            var social_user = users.findWhere({id: cicero_user.id,type: cicero_user.provider});
                            if(social_user == undefined){
                                var new_social_user = new User({id: cicero_user.id, name: cicero_user.displayName, type: cicero_user.provider});
                                users.add(new_social_user);
                            }
                        }
                        Ciceronotifier.on();
                        EventDispatcher.trigger("hide_spinner");
                        Backbone.history.navigate("map", {trigger: true});
                    },this);
                    } else {
                            /*user si slogga*/
                            cicero_user = undefined;
                            firebaseRef.unauth(); <-- i have added these two lines right now but the problem seems unresolved
                            firebaseRef = new Firebase('https://cicero.firebaseio.com');
                            Backbone.history.navigate("login", {trigger: true});
