Laravel Token Builder

This package can generate random tokens which can expires.

Generated token can be used for creating one-time links, or authentication with sms pin and etc.

we have 2 things that can expire genereted tokens:

  • time limit : for example a token can be expired after 2022/05/12
  • usage limit : for example a token can be expired after using it more than 3 times.

Donate me if you like this package 😎 :bowtie:

List of contents

Install

Via Composer

$ composer require shetabit/token-builder

Configure

If you are using Laravel 5.5 or higher then you don't need to add the provider and alias.

In your config/app.php file add these two lines.

# In your providers array.
'providers' => [
    ...
    Shetabit\TokenBuilder\Provider\TokenBuilderServiceProvider::class,
],

# In your aliases array.
'aliases' => [
    ...
    'TokenBuilder' => Shetabit\TokenBuilder\Facade\TokenBuilder::class,
],

then, run the below commands to publish migrations and create tables

php artisan vendor:publish

php artisan migrate

How to use

you can use TokenBuilder facade or Builder class to build tokens.

Generating tokens

In your code, use facade like the below :

use Shetabit\TokenBuilder\Facade\TokenBuilder;

// ...

$tokenObject = $token = TokenBuilder::build();

you can also use Builder :

use Shetabit\TokenBuilder\Builder;

// ...

$builder = new Builder;

$tokenObject = $builder->build();

each tokenObject has a unique value that can be used to recognize it from others and we call it token. you can access to tokenObject unique token using token, see below example:

use Shetabit\TokenBuilder\Facade\TokenBuilder;

// ...

// generate and store token in database
$tokenObject = $token = TokenBuilder::build();

// show token unique value
echo $tokenObject->token;

you can retrieve token and send it to users via email or sms or using it in URLs. it can be used to sms verifications or one-time login pins , etc.

Adding expiration date

you can build a token with auto expiration date. this kind of token will be expired after the specified date.

    use Shetabit\TokenBuilder\Facade\TokenBuilder;

    // ...

    // will be expired after 5 minutes
    $date = Carbon::now()->addMinutes(5);
    $tokenObject = TokenBuilder::setExpireDate($date)->build();

    echo $tokenObject->token; // show unique token
    echo $tokenObject->expired_at; // show expiration datetime

    if ($tokenObject->hasExpired()) {
        echo 'token has expired';
    }

Adding usage limit

you can add usage limit into your tokens. a token will be invalid after the usage has exceeded the limit.

    use Shetabit\TokenBuilder\Facade\TokenBuilder;

    // ...

    // will be expired after 1 usage.
    $tokenObject = TokenBuilder::setUsageLimit(1)->build();

    // use token --> increment the usage counter
    $tokenObject->use();

    echo $tokenObject->token; // show unique token
    echo $tokenObject->usage_count; // show total usages count
    echo $tokenObject->max_usage_limit; // show max usage limit

    // determine if user has used
    if ($tokenObject->hasUsed()) {
        echo 'token has used';
    }

    // determin if token has exceed max usage
    if ($tokenObject->hasExceedMaxUsage()) {
        echo 'token used has exceeded the specified limit';
    }

Validation

you can validate a token using isValid method. a token is valid if has not exceeded the specified limit and has not expired yet.

use Shetabit\TokenBuilder\Facade\TokenBuilder;

// ...

$date = Carbon::now()->addMinutes(5); // will be expired after 5 minutes
$usageLimit = 1; // max usages
$token = TokenBuilder::setExpireDate($date)->setUsageLimit($usageLimit)->build();

if ($token->isValid()) {
    echo 'token is valid';

    $token->use(); // use token (increament usage counter)
} else {
    echo 'token is not valid any more!';
}

you can use a token by running use method. you can expire a token by running markAsExpired method. (this method will update expiration date to current date).

Add relations

you can add a relation to tokens. this can be done in 2 different ways:

use Shetabit\TokenBuilder\Facade\TokenBuilder;
use App\User;

$user = User::first();

/**
 * first example: using TokenBuilder
 **/

$tokenObject = TokenBuilder::setRelatedItem($user)->build();

/**
 * second example: using a main model
 **/

$tokenObject = $user->temporaryTokenBuilder()->build();

// you can access to token's relation using the tokenable
dd($tokenObject->tokenable);

if ($tokenObject->tokenable) {
    echo $tokenObject->tokenable->email;
}

Attach custom data

you can attach custom data into your token. this data will be stored in json format.

use Shetabit\TokenBuilder\Facade\TokenBuilder;

/**
 * first example: using TokenBuilder
 **/

$data = [
    'mobile' => '9373620353',
    'name' => 'John Doe',
];

$tokenObject = TokenBuilder::setData($data)->build();

echo $tokenObject->data['mobile'];

Retrieve tokens

you can retrieve tokenObject using token's unique string

$token = 22325651; // your unique token

// retrieve token object
$tokenObject = TokenBuilder::setUniqueId($token)->findToken();

// retrieve token object if it is valid
$tokenObject = TokenBuilder::setUniqueId($token)->findValidToken();

// retrieve token object using its relation
$tokenObject = $user->temporaryTokenBuilder()->setUniqueId($token)->findToken();

// retrieve token object if it is valid using its relation
$tokenObject = $user->temporaryTokenBuilder()->setUniqueId($token)->findValidToken();

TokenBuilder reference

This is a reference for TokenBuilder methods. TokenBuilder creates a tokenObject (instance of eloquent Token model) if you run build method and searches into data base using findToken and findValidToken.

  • setUniqueId
  • you can build tokens with your custom algoritm and use it as unique id.

      $token = 'jgaZ1z9';
      $tokenObject = TokenBuilder::setUniqueId($token)->build();
      echo $tokenObject->token; // jgaZ1z9
    
  • getUniqueId
  • returns your custom unique id (if not exists, returns null).

  • setData
  • you can attach some data into tokens and retrieve them later.

  • getData

    returns attached data.

  • setExpireDate

    sets an expiration date.

  • getExpireDate

    retrieves expiration date.

  • setUsageLimit

    sets usage limit.

  • getUsageLimit

    retrieves usage limit.

  • setType

    sets token type. you can set type for your tokens. its like a scope for your tokens.

  • getType

    retrieves token type.

  • setRelatedItem

    add a relation to token.

  • getRelatedItem

    retrieve current relation.

  • build

    generate a token.

  • findToken

    find token (being valid or not valid is not important) and return null if not exists.

  • findValidToken

    find token if it is valid and return null if not exists.

Token Reference

  • use

    add 1 to usage counter. (usageCounter = usageCounter + 1)

  • hasUsed

    determine is current token has used and returns a boolean result.

  • hasMaxUsageLimit

    determine if current token max usage is limited and returns a boolean result.

  • hasExpired

    determine if current token has expired or not.

  • markAsExpired

    mark current token as expired.

    notice: this method updates expired_at field to current time (now).

  • isValid

    determines if current token is valid (must not be expired and must not be exceeded max usage limit).

  • tokenable

    returns the token relation if there is any relation, and returns null if no relation exists.
