在Laravel中自定义身份验证

Question

我正在使用Laravel 5.1，并且需要使用具有自己的密码算法的现有用户表。 经过数小时和数小时的研究，我找到了解决方案，下面是步骤。 希望这可以帮助Laravelers。

Answer 1

在config/auth.php文件中， 将驱动程序值设置为自定义。喜欢这个。

... 
'driver' => 'custom', 
... 

在app/Auth目录下创建一个文件CustomUserProvider.php。

<?php 

namespace App\Auth; 

use App\Model\User; 
use Carbon\Carbon; 
use Illuminate\Auth\GenericUser; 
use Illuminate\Contracts\Auth\Authenticatable; 
use Illuminate\Contracts\Auth\UserProvider; 

class CustomUserProvider implements UserProvider{ 

    /** 
    * Retrieve a user by their unique identifier. 
    * 
    * @param mixed $identifier 
    * @return \Illuminate\Contracts\Auth\Authenticatable|null 
    */ 

    public function retrieveById($identifier){ 
     $qry = User::where('id', '=', $identifier); 
     if ($qry->count() > 0){ 
      $user = $qry->select('id', 'firstName', 'lastName', 'city', 'state', 'zipcode', 'email', 'dob' 
       , 'mobilePhone', 'password', 'question', 'answer', 'passwordSalt', 'promoCode', 'createdDate', 'isActivated', 'activationDate' 
       , 'isDeleted', 'firstTimeLogin', 'role', 'remember_token')->first(); 
      return $user; 
     } 
     return NULL; 
    } 


    /** 
    * Retrieve a user by by their unique identifier and "remember me" token. 
    * 
    * @param mixed $identifier 
    * @param string $token 
    * @return \Illuminate\Contracts\Auth\Authenticatable|null 
    */ 

    public function retrieveByToken($identifier, $token){ 
     $qry = User::where('id', '=', $identifier) 
      ->where('remember_token', '=', $token); 
     if ($qry->count() > 0){ 
      $user = $qry->select('id', 'firstName', 'lastName', 'city', 'state', 'zipcode', 'email', 'dob' 
       , 'mobilePhone', 'password', 'question', 'answer', 'passwordSalt', 'promoCode', 'createdDate', 'isActivated', 'activationDate' 
       , 'isDeleted', 'firstTimeLogin', 'role', 'remember_token')->first(); 
      return $user; 
     } 
     return NULL; 
    } 


    /** 
    * Update the "remember me" token for the given user in storage. 
    * 
    * @param \Illuminate\Contracts\Auth\Authenticatable $user 
    * @param string $token 
    * @return void 
    */ 

    public function updateRememberToken(Authenticatable $user, $token){ 
     $user->setRememberToken($token); 
     $user->save(); 
    } 


    /** 
    * Retrieve a user by the given credentials. 
    * 
    * @param array $credentials 
    * @return \Illuminate\Contracts\Auth\Authenticatable|null 
    */ 

    public function retrieveByCredentials(array $credentials){ 
     $qry = User::where('email', 'like', $credentials['email']); 

     if ($qry->count() > 0){ 
      $user = $qry->select('id', 'firstName', 'lastName', 'city', 'state', 'zipcode', 'email', 'dob' 
       , 'mobilePhone', 'password', 'question', 'answer', 'passwordSalt', 'promoCode', 'createdDate', 'isActivated', 'activationDate' 
       , 'isDeleted', 'firstTimeLogin', 'role', 'remember_token')->first(); 
      return $user; 
     } 
     return NULL; 
    } 


    /** 
    * Validate a user against the given credentials. 
    * 
    * @param \Illuminate\Contracts\Auth\Authenticatable $user 
    * @param array $credentials 
    * @return bool 
    */ 

    public function validateCredentials(Authenticatable $user, array $credentials){ 
     $salt = base64_decode($user->passwordSalt); 
     $password = $credentials['password']; 
     $utf16Password = mb_convert_encoding($password, 'UTF-16LE', 'UTF-8'); 
     $calculatedPassword = base64_encode(sha1($salt . $utf16Password, true)); 
     if ($user->email == $credentials['email'] && $user->getAuthPassword() == $calculatedPassword){ 
      return true; 
     } 
     return false; 
    } 
} 

?> 

接下来，在app/Providers目录下创建一个文件'CustomAuthProvider.php'。

<?php 

namespace App\Providers; 

use App\Auth\CustomUserProvider; 
use Illuminate\Support\ServiceProvider; 

class CustomAuthProvider extends ServiceProvider{ 

    /** 
    * Bootstrap the application services. 
    * 
    * @return void 
    */ 

    public function boot(){ 
     $this->app['auth']->extend('custom', function(){ 
      return new CustomUserProvider(); 
     }); 
    } 


    /** 
    * Register the application services. 
    * 
    * @return void 
    */ 

    public function register(){ 
     // 
    } 


} 

?> 

就是这样。
