告别身份验证难题：如何使用Smart-IDPHPClient实现安全便捷的身份验证

发布时间 - 2025-09-01 00:00:00 点击率：次

在构建需要安全身份验证的 Web 应用程序时，我遇到了一个常见的问题：如何集成一个既安全又用户友好的身份验证解决方案。传统的用户名/密码方式已经无法满足日益增长的安全需求，而复杂的双因素认证方案又可能降低用户体验。

这时，我发现了 smart-id，一种基于移动设备的数字身份验证解决方案。smart-id 允许用户使用他们的移动设备进行身份验证，无需记住复杂的密码或携带额外的硬件设备。然而，如何将 smart-id 集成到我的 php 应用程序中，成为了一个新的挑战。

经过一番研究，我找到了

sk-id-solutions/smart-id-php-client

这个 Composer 包，它提供了一个简洁的 PHP 接口，可以轻松地与 Smart-ID 服务进行交互。

安装

首先，你需要使用 Composer 安装该库：

composer require sk-id-solutions/smart-id-php-client "2.3.2"

配置客户端

安装完成后，你需要配置客户端的详细信息，包括 Relying Party UUID、Relying Party Name 和 Smart-ID 服务的 URL。更重要的是，为了防止中间人攻击，你需要设置 HTTPS pinning，通过指定信任的 SSL 证书的公钥哈希来确保与 Smart-ID 服务的安全连接。

use SK\SmartId\Client\Client;

$this->client = new Client();
$this->client
    ->setRelyingPartyUUID( '00000000-0000-0000-0000-000000000000' ) // In production replace with your UUID
    ->setRelyingPartyName( 'DEMO' ) // In production replace with your name
    ->setHostUrl( 'https://sid.demo.sk.ee/smart-id-rp/v2/' ) // In production replace with production service URL
        // in production replace with correct server SSL key
    ->setPublicSslKeys("sha256//Ps1Im3KeB0Q4AlR+/J9KFd/MOznaARdwo4gURPCLaVA=");

使用语义标识符进行身份验证

接下来，你可以使用语义标识符（例如个人身份号码）来启动身份验证流程。这个过程包括生成一个随机的身份验证哈希，并将其呈现给用户，以便他们在 Smart-ID 应用程序中进行验证。

use SK\SmartId\Client\Api\Authentication\AuthenticationRequestBuilder;
use SK\SmartId\Client\Api\Authentication\AuthenticationResponseValidator;
use SK\SmartId\Client\Api\Authentication\NationalIdentity;

$semanticsIdentifier = SemanticsIdentifier::builder()
    ->withSemanticsIdentifierType('PNO')
    ->withCountryCode('LT')
    ->withIdentifier('30303039914')
    ->build();

// For security reasons a new hash value must be created for each new authentication request
$authenticationHash = AuthenticationHash::generate();

$verificationCode = $authenticationHash->calculateVerificationCode();

// display verification code to the user
echo "Verification code: " . $verificationCode . "\n";

$authenticationResponse = null;
try
{
  $authenticationResponse = $this->client->authentication()
      ->createAuthentication()
      ->withSemanticsIdentifier( $semanticsIdentifier )
      ->withAuthenticationHash( $authenticationHash )
      ->withCertificateLevel( CertificateLevelCode::QUALIFIED ) // Certificate level can either be "QUALIFIED" or "ADVANCED"
      ->withAllowedInteractionsOrder((array(
          Interaction::ofTypeVerificationCodeChoice("Enter awesome portal?"),
          Interaction::ofTypeDisplayTextAndPIN("Enter awesome portal?"))))
      ->authenticate(); // this blocks until user has responded
}
catch (UserRefusedException $e) {
  throw new RuntimeException("You pressed cancel in Smart-ID app.");
}
catch (UserSelectedWrongVerificationCodeException $e) {
  throw new RuntimeException("You selected wrong verification code in Smart-ID app. Please try again. ");

}
catch (UserAccountException $e) {
  throw new RuntimeException("Unable to authenticate due to a problem with your Smart-ID account.");
}
catch (EnduringSmartIdException $e) {
  throw new RuntimeException("Problem with connecting to Smart-ID service. Please try again later.");
}
catch (SmartIdException $e) {
  throw new RuntimeException("Smart-ID authentication process failed for uncertain reason: ". $e);
}

// create a folder with name "trusted_certificates" and set path to that folder here:
$pathToFolderWithTrustedCertificates = __DIR__ . '/../../../resources';

$authenticationResponseValidator = new AuthenticationResponseValidator($pathToFolderWithTrustedCertificates);
$authenticationResult = $authenticationResponseValidator->validate( $authenticationResponse );


if ($authenticationResult->isValid()) {
  echo "Hooray! Authentication result is valid";
}
else {
   throw new RuntimeException("Error! Response is not valid! Error(s): ". implode(",", $authenticationResult->getErrors()));
}



$authenticationIdentity = $authenticationResult->getAuthenticationIdentity();

echo "hello name: " . $authenticationIdentity->getGivenName() . ' ' . $authenticationIdentity->getSurName() . "\n";
echo "from " . $authenticationIdentity->getCountry() . "\n";
echo "born " . $authenticationIdentity->getDateOfBirth()->format("D d F o") . "\n";

// you might need this if you want to start authentication with document number
echo "Authenticated user documentNumber is: ".$authenticationResponse->getDocumentNumber(). "\n";
