When developing Laravel projects, it is often necessary to use a unique identifier (UUID) to ensure the uniqueness of the data. However, generating and validating UUIDs can encounter some challenges, such as version selection and compatibility issues. This article will introduce how to use the webpatser/laravel-uuid library to solve these problems and improve development efficiency.

Install

Using the webpatser/laravel-uuid library is very simple, just install it through Composer:

 <code>composer require "webpatser/laravel-uuid:^3.0"</code>

After installation, Laravel's automatic package discovery function automatically recognizes and configures the library to make it available immediately.

Basic use

Generating a UUID is very simple, just call Uuid::generate() method:

 <code class="language-php">Uuid::generate()</code>

This will generate a version 1 UUID object with a randomly generated MAC address. If you need to convert the UUID to a string, you can use:

 <code class="language-php">(string) Uuid::generate()</code>

or

 <code class="language-php">Uuid::generate()->string</code>

Advanced use

The webpatser/laravel-uuid library supports the generation and verification of multiple UUID versions:

• Version 1 (based on time): Uuid::generate(1, '00:11:22:33:44:55')
• Version 3 (based on name, using MD5 hash): Uuid::generate(3, 'test', Uuid::NS_DNS)
• Version 4 (completely random): Uuid::generate(4)
• Version 5 (based on name, using SHA-1 hash): Uuid::generate(5, 'test', Uuid::NS_DNS)

In addition, the library also provides functions such as importing UUIDs, extraction time and version:

 <code class="language-php">$uuid = Uuid::import('d3d29d70-1d25-11e3-8591-034165a3a613'); dd($uuid->time); // 提取时间dd($uuid->version); // 提取版本</code>

UUID generation in Eloquent model

If you want to automatically generate UUIDs in the Laravel model, you can add the following code to the boot method of the model:

 <code class="language-php">public static function boot() { parent::boot(); self::creating(function ($model) { $model->uuid = (string) Uuid::generate(4); }); }</code>

This way, whenever a new record is created, a version 4 UUID will be automatically generated.

Model binding to UUID instead of primary key

If you want to use a UUID instead of a primary key in the URL, you can override getRouteKeyName method in the model:

 <code class="language-php">public function getRouteKeyName() { return 'uuid'; }</code>

In this way, when injecting the model into the resource controller method, the correct record will be obtained based on the UUID.

verify

Verifying the UUID is also simple, just use the uuid rules in the Laravel validator:

 <code class="language-php">'uuid-field' => 'uuid'</code>

Or create a validator from scratch:

 <code class="language-php">$uuid = Uuid::generate(); $validator = Validator::make(['uuid' => $uuid], ['uuid' => 'uuid']); dd($validator->passes());</code>

Summarize

The webpatser/laravel-uuid library not only simplifies the generation and verification process of UUIDs, but also provides support and advanced features of multiple versions, making it more efficient and flexible to handle UUIDs in Laravel projects. Whether newbies or experienced developers, they can benefit from it and improve development efficiency and code quality.
