• ทำการติดตั้ง Laravel Package ผ่าน Composer

# C:\Apache24\htdocs\laravel> composer require predis/predis

• ทำการแก้ไขไฟล์ config/app.php

'redis' => [

    'client' => 'predis',

    'default' => [
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'password' => env('REDIS_PASSWORD', null),
        'port' => env('REDIS_PORT', 6379),
        'database' => env('REDIS_DB', 0),
        'read_write_timeout' => 60,
    ],

    'cache' => [
        'host' => env('REDIS_HOST', '127.0.0.1'),
        'password' => env('REDIS_PASSWORD', null),
        'port' => env('REDIS_PORT', 6379),
        'database' => env('REDIS_CACHE_DB', 1),
    ],

• ทำการ Create Route ในไฟล์ routes/web.php

Route::post('otp/generate','OtpController@index');
Route::post('otp/verified','OtpController@verified');
Route::get('otp/session','OtpController@session');

• ทำการแก้ไขไฟล์ app/Http/Controller/OtpController.php
