Laravel 身份验证与雄辩的角色驱动程序-php问题

laravel authentication with eloquent driver on roles(Laravel 身份验证与雄辩的角色驱动程序)

本文介绍了Laravel 身份验证与雄辩的角色驱动程序的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试对我的 Laravel 应用程序中的用户进行身份验证.

I am trying to authenticate users in my Laravel application.

我遇到了以下问题:

在 auth.php 中使用驱动程序数据库:我可以使用 auth::attempt() 登录，并且 auth::check 正在运行，但我无法验证登录用户是否具有特定角色.
在 auth.php 中使用驱动程序 eloquent:我可以使用 auth::attempt() 登录，但 auth::check 不起作用.但是，我可以检查登录用户的角色.

using driver database in auth.php: I can login using auth::attempt(), and auth::check is working, but I can't validate if the logged in user has a certain role.
using driver eloquent in auth.php: I can login using auth::attempt(), but auth::check is not working. I can however check the role of the logged in user.

编辑(问题):我该如何解决这个问题，以便仅使用一个驱动程序，我就可以进行完整的身份验证和角色检查?

edit (question): How can I fix this so that with only one of the drivers, i can do a complete authentication and role check?

迁移表:

Schema::create('users', function ($table) {
        $table->increments('id');
        $table->integer('group_id')->unsigned();
        $table->string('name', 64);
        $table->string('email', 64)->unique();
        $table->string('username', 64)->unique();
        $table->string('phone', 13);
        $table->string('address', 64);
        $table->boolean('isresponsible');
        $table->string('password', 64);
        $table->rememberToken()->nullable();
    });
Schema::create('roles', function ($table) {
        $table->increments('id');
        $table->string('name');
    });

Schema::create('users_roles', function ($table) {
            $table->integer('user_id')->unsigned();
            $table->integer('role_id')->unsigned();
        }
    );
Schema::table('users_roles', function($table){
        $table->foreign('user_id')->references('id')->on('users')->onDelete('cascade');
        $table->foreign('role_id')->references('id')->on('roles');
    });

模型类用户

<?php
use IlluminateAuthUserTrait;`
use IlluminateAuthUserInterface;`
use IlluminateAuthRemindersRemindableTrait;
use IlluminateAuthRemindersRemindableInterface;

class User extends Eloquent implements UserInterface, RemindableInterface {


use UserTrait, RemindableTrait;

/**
 * The database table used by the model.
 *
 * @var string
 */
protected $table = 'users';
public $timestamps = false;

public static $rules = ['name' => 'required', 'group_id' => 'required', 'email' => 'required', 'phone' => 'required'];
protected $fillable = ['name', 'group_id', 'email', 'phone', 'address', 'isresponsible', 'password'];

/**
 * The attributes excluded from the model's JSON form.
 *
 * @var array
 */
protected $hidden = array('password', 'remember_token');

public function group()
{
    return $this->belongsTo('Group');
}

public function userroles(){
    return $this->hasMany('Userrole');
}

public function roles()
{
    return $this->belongsToMany('Role', 'users_roles');
}

public function hasRole($check)
{
    dd($this->roles->toArray());
    return in_array($check, array_fetch($this->roles->toArray(), 'name'));
}

public function setBasicPassword($id){
    $user = User::find($id);
    $user->password = Hash::make('changeme');
    $user->save();
}

public function isValid()
{
    $validation = Validator::make($this->attributes, static::$rules);
    if ($validation->passes()) return true;
    $this->messages = $validation->messages();
    return false;
}


/**
 * Get the e-mail address where password reminders are sent.
 *
 * @return string
 */
public function getReminderEmail()
{
    // TODO: Implement getReminderEmail() method.
}

/**
 * Get the unique identifier for the user.
 *
 * @return mixed
 */
public function getAuthIdentifier()
{
    return $this->email;
}

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

/**
 * Get the token value for the "remember me" session.
 *
 * @return string
 */
public function getRememberToken()
{
    return $this->remember_token;
}

public function setRememberToken($value)
{
    $this->remember_token = $value;
}

public function getRememberTokenName()
{
    return 'remember_token';
}
}

模型类角色

class Role extends Eloquent
{

protected $table = 'roles';
public $timestamps = false;

public static $rules = ['role_id' => 'required', 'name' => 'required'];
protected $fillable = ['name'];

/**
 * Get users with a certain role
 */
public function userroles()
{
    return $this->belongsToMany('User', 'users_roles');
}
}

HomeController 认证功能

HomeController authentication function

 public function authenticate(){
    $rules = array(
        'email'    => 'required|email',
        'password' => 'required|alphaNum|min:3'
    );
    $validator = Validator::make(Input::all(), $rules);
    if ($validator->fails()) {
        return Redirect::to('login')
            ->withErrors($validator)
            ->withInput(Input::except('password'));
    } else {
        $userdata = array(
            'email' => Input::get('email'),
            'password' => Input::get('password')
        );
        if (Auth::attempt($userdata, true)) {
            return Redirect::action('HomeController@index');

        } else {
            return Redirect::action('HomeController@login')->withInput();
        }
    }
}

使用数据库驱动程序
- auth:attempt() 和 auth::check 正在工作

USING THE DATABASE DRIVER
- auth:attempt() and auth::check are working

$this->beforeFilter('admin', ['only' => ['index']]); //filter in controller
//filter in filters;php
Route::filter('admin', function()
{
if(!Auth::check()) return Redirect::action('HomeController@index');
if(!Auth::user()->hasRole('admin')) return View::make('errors.401');
});

这会因调用未定义的方法 IlluminateAuthGenericUser::hasRole()"而失败

This fails with 'Call to undefined method IlluminateAuthGenericUser::hasRole()'

EDIT 数据库 驱动程序返回一个 GenericUser 对象，我需要自己的 User 对象.不知道哪里可以改.

EDIT The database driver return a GenericUser Object, and I need my own User object. Don't know where I can change this.

解决方法:我不想使用这个，丑陋的代码和过滤器(或视图)不应该需要这样做

Workaround:I'd rather not use this, ugly code and filters (or views) should not need to do this

Route::filter('admin', function()
{
    if(!Auth::check()) return Redirect::action('HomeController@index');
    $user = User::find((Auth::user()->id));
    if(!$user->hasRole('admin')){ return View::make('errors.401');}
});

使用 ELOQUENT 驱动程序
