        laravel ramsey/uuid唯一識別碼應(yīng)用實戰(zhàn)

        時間:2024-10-01來源:風(fēng)信官網(wǎng) 點擊: 1946次
        在項目開發(fā)過程中經(jīng)常會遇到需要唯一標(biāo)識碼的功能,風(fēng)信建站laravel開發(fā)項目使用ramsey/uuid包進行唯一識別碼的應(yīng)用,分享經(jīng)驗如下:
         
        github項目地址:https://github.com/ramsey/uuid
         
        安裝軟件包:
         
        composer require ramsey/uuid
         
        安裝過程如下:
        Using version ^3.8 for ramsey/uuid
        ./composer.json has been updated
        Loading composer repositories with package information
        Updating dependencies (including require-dev)
        Nothing to install or update
        Writing lock file
        Generating optimized autoload files
        > Illuminate\Foundation\ComposerScripts::postAutoloadDump
        > @php artisan package:discover --ansi
        Discovered Package: [32mbeyondcode/laravel-dump-server[39m
        Discovered Package: [32mfideloper/proxy[39m
        Discovered Package: [32mintervention/image[39m
        Discovered Package: [32mjenssegers/agent[39m
        Discovered Package: [32mlaravel/tinker[39m
        Discovered Package: [32mmews/captcha[39m
        Discovered Package: [32mnesbot/carbon[39m
        Discovered Package: [32mnunomaduro/collision[39m
        [32mPackage manifest generated successfully.[39m
         
        完成之后,我們在項目的控制器中進行應(yīng)用
         
        use Ramsey\Uuid\Uuid;
         
        $data = Uuid::uuid4();
        $appid = $data->getHex();
        dd($appid);
         
        獲得結(jié)果如下:
         
        "81b6c500e42d43d0a77a99bb7d3ab8a5"
         
        官方示例代碼:
         
        
        require 'vendor/autoload.php';
        
        use Ramsey\Uuid\Uuid;
        use Ramsey\Uuid\Exception\UnsatisfiedDependencyException;
        
        try {
        
            // Generate a version 1 (time-based) UUID object
            $uuid1 = Uuid::uuid1();
            echo $uuid1--->toString() . "\n"; // i.e. e4eaaaf2-d142-11e1-b3e4-080027620cdd
        
            // Generate a version 3 (name-based and hashed with MD5) UUID object
            $uuid3 = Uuid::uuid3(Uuid::NAMESPACE_DNS, 'php.net');
            echo $uuid3->toString() . "\n"; // i.e. 11a38b9a-b3da-360f-9353-a5a725514269
        
            // Generate a version 4 (random) UUID object
            $uuid4 = Uuid::uuid4();
            echo $uuid4->toString() . "\n"; // i.e. 25769c6c-d34d-4bfe-ba98-e0ee856f3e7a
        
            // Generate a version 5 (name-based and hashed with SHA1) UUID object
            $uuid5 = Uuid::uuid5(Uuid::NAMESPACE_DNS, 'php.net');
            echo $uuid5->toString() . "\n"; // i.e. c4a760a8-dbcf-5254-a0d9-6a4474bd1b62
        
        } catch (UnsatisfiedDependencyException $e) {
        
            // Some dependency was not met. Either the method cannot be called on a
            // 32-bit system, or it can, but it relies on Moontoast\Math to be present.
            echo 'Caught exception: ' . $e->getMessage() . "\n";
        
        }
