在角色上使用雄辩的驱动程序进行laravel身份验证

标签: php authentication laravel eloquent

我正在尝试在Laravel应用程序中验证用户身份。

我遇到以下问题:

  • 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有某种角色。
  • 在auth.php中使用驱动程序 eloquent :我可以使用auth :: attempt()登录,但是auth :: check无效。但我可以检查登录用户的角色。

编辑(问题):我如何解决这个问题,以便只使用其中一个驱动程序,我可以进行完整的身份验证和角色检查?

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 Illuminate\Auth\UserTrait;`
use Illuminate\Auth\UserInterface;`
use Illuminate\Auth\Reminders\RemindableTrait;
use Illuminate\Auth\Reminders\RemindableInterface;

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

 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正在运行

$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');
});

这失败了'调用未定义的方法Illuminate \ Auth \ GenericUser :: hasRole()'

编辑 数据库驱动程序返回GenericUser对象,我需要自己的User对象。不知道我可以在哪里改变它。

解决方法:我宁愿不使用它,丑陋的代码和过滤器(或视图)不应该这样做

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');}
});

使用优秀的驾驶员

  • auth :: attempt()成功
  • auth :: check()失败
  • 过滤器没有错误

1 个答案:

答案 0 :(得分:2)

问题是您getAuthIdentifier()的实施。此方法实际上应该返回表的主键,而不是用于登录的用户名。

所以你的看起来应该是这样的:

public function getAuthIdentifier(){
    return $this->id;
}

或者实际上,我建议您更多地清理模型,因为所有getSomeAuthStuff方法都是在两个特征中实现的。

使用default model on github作为基础并添加所有自定义代码(角色方法,规则等)

背景信息

getAuthIdentifier()返回的值将存储在会话中 之后使用check()时,retrieveById会调用UserProviderEloquentUserProvider执行此操作:

public function retrieveById($identifier)
{
    return $this->createModel()->newQuery()->find($identifier);
}

它使用find()按主键搜索模型(通常是id
