Laravel 4验证与Facebook（无密码验证） [英] Laravel 4 Auth with Facebook (no password authentication)

问题描述

我试图建立与Laravel 4的认证系统与Facebook登录。我现在用的是madewithlove / laravel-的oauth2包Laravel 4。

I'm trying to set up an authentication system with Laravel 4 with a Facebook login. I am using the madewithlove/laravel-oauth2 package for Laravel 4.

当然，没有密码对用户洛与Facebook添加到我的数据库。我，然而，试图检查，看是否有用户ID已经在数据库中，以确定是否我应该创建一个新的实体，或只要登录当前之一。我想用验证命令来做到这一点。我有一个名为粉丝表。

Of course, there is no password to add to my database upon a user loggin in with Facebook. I am, however, trying to check to see if a user id is in the database already to determine if I should create a new entity, or just log in the current one. I would like to use the Auth commands to do this. I have a table called "fans".

这是我用什么样的工作：

This is what I'm working with:

 $fan = Fan::where('fbid', '=', $user['uid']);

                if(is_null($fan)) {

                  $fan = new Fan;

                  $fan->fbid = $user['uid'];
                  $fan->email = $user['email'];
                  $fan->first_name = $user['first_name'];
                  $fan->last_name = $user['last_name'];
                  $fan->gender = $user['gender'];
                  $fan->birthday = $user['birthday'];
                $fan->age = $age;
                $fan->city = $city;
                $fan->state = $state;
                  $fan->image = $user['image'];

                  $fan->save();

                  return Redirect::to('fans/home');

                }

                else {

                  Auth::login($fan);
                  return Redirect::to('fans/home');

               }

风扇型号：

<?php

class Fan extends Eloquent {
    protected $guarded = array();

    public static $rules = array();
}

当我运行它，我得到的错误：

When I run this, I get the error:

Argument 1 passed to Illuminate\Auth\Guard::login() must be an instance of Illuminate\Auth\UserInterface, instance of Illuminate\Database\Eloquent\Builder given

编辑：当我使用： $扇=风扇::在哪里（'fbid'，'='，$用户['UID']） - ＆gt;首先（）;

我得到的错误：

Argument 1 passed to Illuminate\Auth\Guard::login() must be an instance of Illuminate\Auth\UserInterface, null given, called in /Applications/MAMP/htdocs/crowdsets/laravel-master/vendor/laravel/framework/src/Illuminate/Auth/Guard.php on line 368 and defined

我不知道为什么它给我这个错误。你对我怎样才能使这项工作的建议吗？谢谢你的帮助。

I do not know why it is giving me this error. Do you have suggestions on how I can make this work? Thank you for your help.

推荐答案

您必须实现的UserInterface到模型的验证才能正常工作

You have to implement UserInterface to your model for Auth to work properly

use Illuminate\Auth\UserInterface;
class Fan extends Eloquent implements UserInterface{
...
public function getAuthIdentifier()
{
    return $this->getKey();
}

/**
 * Get the password for the user.
 *
 * @return string
 */
public function getAuthPassword()
{
    return $this->password;
}
}

getAuthIdentifier和getAuthPassword是抽象方法，必须在你的类实现的UserInterface实施

getAuthIdentifier and getAuthPassword are abstract method and must be implemented in you class implementing UserInterface
