在config/auth.php文件中，将驱动程序值设置为自定义.像这样.

in config/auth.php file, set driver value to custom. like this.

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

在app/Auth目录中创建文件'CustomUserProvider.php.

create a file 'CustomUserProvider.php in app/Auth directory.

<?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目录中创建一个文件'CustomAuthProvider.php'.

next, create a file 'CustomAuthProvider.php' in app/Providers directory.

<?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.
