<"color: #ff0000">注册服务


创建文件 /app/Providers/MyCryptServiceProvider.php 代码如下:


其实也可以在AppServiceProvider中注册，就不用另外建个MyCryptServiceProvider.php文件了


而且在/config/app.php中一般也已经有了AppServiceProvider的声明


<"color: #ff0000">在配置中声明


文件地址 /config/app.php 在providershe和aliases中添加


'providers' => [
 \App\Providers\MyCryptServiceProvider::class,
],

'aliases' => [
 'MyCrypt' => \App\Facades\CryptFacades::class,
]


编写自定义加密解密服务的配置文件


/config/crypt.php 因为我写的CryptService有用到配置文件，所以需要再添加个配置文件。在实际项目中，可以根据需要自行设置配置文件和加密服务类。


<"digest_alg" => "sha512",
   "private_key_bits" => 1024,
   "private_key_type" => OPENSSL_KEYTYPE_RSA,
  ]
 ],
 'rsa_data'=>[
  'path'=>DIRECTORY_SEPARATOR.'storage'.DIRECTORY_SEPARATOR.'rsakey'.DIRECTORY_SEPARATOR,
  'private_key_file_name'=>'private.pem',
  'public_key_file_name' =>'public.pem',
  'openssl_config'=>[
   "digest_alg" => "sha512",
   "private_key_bits" => 1024,
   "private_key_type" => OPENSSL_KEYTYPE_RSA,
  ]
 ]
];


在Controller中使用的示例


1、artisan创建Controller文件




php artisan make:controller IndexController


2、编辑IndexController




<"abcd";
  $long = "
   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
   aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa";

  $req['short'] = $short;
  $req['short_private_encrypt'] = $crypt->encryptPrivate($short);
  $req['short_public_decrypt'] = $crypt->decryptPublic($req['short_private_encrypt']);

  $req['long'] = $long;
  $req['long_private_encrypt'] = $crypt->encryptPrivate($long);
  $req['long_public_decrypt'] = $crypt->decryptPublic($req['long_private_encrypt']);
  dump($req);
  //dd($req);
 }
}


3、在/routes/web.php添加路由




Route::get('/test', 'IndexController@test');


4、浏览器访问验证结果
