应用场景：老系统使用TP框架，采用的是MD5加密，现用Laravel框架重构

1. 新建MD5Hasher类文件，放在App/Helpers下

<?php

namespace App\Helpers\Hasher;

use Illuminate\Contracts\Hashing\Hasher;

class MD5Hasher implements Hasher
{
    public function check($value, $hashedValue, array $options = [])
    {

        return $this->make($value) === $hashedValue;
    }

    public function needsRehash($hashedValue, array $options = [])
    {
        return false;
    }

    public function make($value, array $options = [])
    {
        $value = env('SALT', '').$value;

        return md5($value);
    }

}

 

2.创建服务提供者

php artisan make:provider MD5HashServiceProvider
<?php

namespace App\Providers;

use App\Helpers\Hasher\MD5Hasher;
use Illuminate\Support\ServiceProvider;

class MD5HashServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap the application services.
     *
     * @return void
     */
    public function boot()
    {
        $this->app->singleton('hash', function () {
            return new MD5Hasher;
        });
    }

    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {
        //
    }

    public function provides()
    {
        return ['hash'];
    }
}

3.在app/config.php的prociders中将

Illuminate\Hashing\HashServiceProvider::class,

替换为下面的或者注释掉上面的

\App\Providers\MD5HashServiceProvider::class,

4.找到项目的composer.json文件下的autoload数组 中添加classmap

 "classmap": [
           "app/Helpers/MD5Hasher"
        ],

 

5.执行

composer dumpautoload

6.最后即可测试
