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
