它是 https://github.com/greenter/xmldsig 的分支，对UPC的签名请求做了少量修改。

XmlDSig - Greenter

此库用于根据UPC规则签名请求。

需要 .PEM 证书，您可以使用以下示例将 .PFX 证书转换为所需的格式。

安装

从 packagist 使用Composer进行安装。

composer require paycore/xmldsig

示例

use Greenter\XMLSecLibs\Sunat\SignedXml;

require 'vendor/autoload.php';

$xmlData = file_get_contents('path-dir/20600995805-01-F001-1.xml');
$certPath = 'path-dir/SFSCert.pem'; // Convertir pfx to pem 

$signer = new SignedXml();
$signer->setCertificateFromFile($certPath); // You can also use $signer->setCertificate ($certData);

$xmlSigned = $signer->signXml($xmlData);

header('Content-Type: text/xml');
echo $xmlSigned;
