前言
本文介紹的是laravel 5.3中自定義加密服務(wù)的方案，利用laravel的服務(wù)容器，實(shí)現(xiàn)自定義加密服務(wù)注冊(cè)(示例是支持長字符串的RSA加密)，下面來看看詳細(xì)的介紹：
創(chuàng)建加密解密服務(wù)類
文件地址 /app/Service/Common/CryptService.php 代碼如下
下面這個(gè)是個(gè)人寫的支持長字符串的RSA加密類作為示例，自定義加密的話只需更改這個(gè)文件的代碼就好，其它操作只是為了實(shí)現(xiàn)依賴注入。
<?phpnamespace App/Service/Common;class CryptService{ public $config,$keypath, $prikey_path, $pubkey_path, $prikey, $pubkey , $private_key_size; public function select($select = 'rsa_api') { $config = config('crypt'); if (array_key_exists($select, $config)) { $this->config = $config[$select]; $this->private_key_size = $this->config['openssl_config']['private_key_bits']; } else { return false; } $this->keypath = dirname(dirname(dirname(__DIR__))) . $this->config['path']; if(!file_exists($this->keypath)){ mkdir($this->keypath,"0777",true); } $this->prikey_path = $this->keypath . $this->config['private_key_file_name']; $this->pubkey_path = $this->keypath . $this->config['public_key_file_name']; if (file_exists($this->prikey_path)) $this->prikey = file_get_contents($this->prikey_path); if (file_exists($this->pubkey_path)) $this->pubkey = file_get_contents($this->pubkey_path); return $this; } public function makeKey() { $res = openssl_pkey_new($this->config['openssl_config']); openssl_pkey_export($res, $this->prikey); file_put_contents($this->prikey_path, $this->prikey); $pubkey = openssl_pkey_get_details($res); $this->pubkey = $pubkey['key']; file_put_contents($this->pubkey_path, $this->pubkey); return $test = ['prikey' => $this->prikey, 'pubkey' => $this->pubkey]; } public function encryptPrivate($data){ $crypt = $this->encrypt_split($data); $crypted = ''; foreach ($crypt as $k=>$c){ if($k!=0) $crypted.="@"; $crypted.=base64_encode($this->doEncryptPrivate($c)); } return $crypted; } public function encryptPublic($data){ $crypt = $this->encrypt_split($data); $crypted = ''; foreach ($crypt as $k=>$c){ if($k!=0) $crypted.="@"; $crypted.=base64_encode($this->doEncryptPublic($c)); } return $crypted; } public function decryptPublic($data){ $decrypt = explode('@',$data); $decrypted = ""; foreach ($decrypt as $k=>$d){ $decrypted .= $this->doDecryptPublic(base64_decode($d)); } return $decrypted; } public function decryptPrivate($data){ $decrypt = explode('@',$data); $decrypted = ""; foreach ($decrypt as $k=>$d){ $decrypted .= $this->doDecryptPrivate(base64_decode($d)); } return $decrypted; } private function encrypt_split($data){ $crypt=[];$index=0; for($i=0; $i<strlen($data); $i+=117){ $src = substr($data, $i, 117); $crypt[$index] = $src; $index++; } return $crypt; } private function doEncryptPrivate($data) { $rs = ''; if (@openssl_private_encrypt($data, $rs, $this->prikey) === FALSE) { return NULL; } return $rs; } private function doDecryptPrivate($data) { $rs = ''; if (@openssl_private_decrypt($data, $rs, $this->prikey) === FALSE) { return null; } return $rs; } private function doEncryptPublic($data){ $rs = ''; if (@openssl_public_encrypt($data, $rs, $this->pubkey) === FALSE) { return NULL; } return $rs; } private function doDecryptPublic($data) { $rs = ''; if (@openssl_public_decrypt($data, $rs, $this->pubkey) === FALSE) { return null; } return $rs; }}創(chuàng)建門面facades
文件地址 /app/Facades/CryptFacades.php 代碼如下：
<?phpnamespace App/Facades;use /Illuminate/Support/Facades/Facade;class CryptFacades extends Facade{ public static function getFacadeAccessor() { return 'MyCrypt'; }}注冊(cè)服務(wù)
創(chuàng)建文件 /app/Providers/MyCryptServiceProvider.php 代碼如下:
其實(shí)也可以在AppServiceProvider中注冊(cè)，就不用另外建個(gè)MyCryptServiceProvider.php文件了
而且在/config/app.php中一般也已經(jīng)有了AppServiceProvider的聲明
<?phpnamespace App/Providers;use App/Service/Common/CryptService;use Illuminate/Support/ServiceProvider;class MyCryptServiceProvider extends ServiceProvider{ /** * Bootstrap the application services. * * @return void */ public function boot() { // } /** * Register the application services. * * @return void */ public function register() { /App::bind('MyCrypt',CryptService::class); }}在配置中聲明
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,]
編寫自定義加密解密服務(wù)的配置文件
/config/crypt.php 因?yàn)槲覍懙腃ryptService有用到配置文件，所以需要再添加個(gè)配置文件。在實(shí)際項(xiàng)目中，可以根據(jù)需要自行設(shè)置配置文件和加密服務(wù)類。
<?php//基于laravel根目錄，分隔符最好是用 DIRECTORY_SEPARATOR 常量代替return [ 'rsa_api' => [ 'path'=>DIRECTORY_SEPARATOR.'storage'.DIRECTORY_SEPARATOR.'rsakey'.DIRECTORY_SEPARATOR, 'private_key_file_name'=>'private_key.pem', 'public_key_file_name' =>'public_key.pem', 'openssl_config'=>[ "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創(chuàng)建Controller文件
php artisan make:controller IndexController
2、編輯IndexController
<?phpnamespace App/Http/Controllers;use Illuminate/Http/Request;use MyCrypt;class IndexController extends Controller{ public function test(){ $crypt = MyCrypt::select('rsa_api'); $crypt->makeKey(); $short = "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、瀏覽器訪問驗(yàn)證結(jié)果
總結(jié)
