导入PDF并用Symfony签名 [英] Import a PDF and sign it with Symfony
问题描述
我需要签署一个现有的pdf文件.
I need to sign an existing pdf.
我正在使用Symfony 3.4.12和捆绑包 https://packagist.org/包/whiteoctober/tcpdf-bundle 来签名pdf.
I'm using Symfony 3.4.12 and the bundle https://packagist.org/packages/whiteoctober/tcpdf-bundle to sign pdf's.
在服务中,我添加了此部分:
Inside the services I added this part:
AppBundle\Controller\AController:
class: AppBundle\Controller\AController
arguments: ['@white_october.tcpdf']
在控制器内部,我正在使用它;
Inside the Controller I'm using this;
use WhiteOctober\TCPDFBundle\Controller\TCPDFController;
使用此代码,我可以下载正确签名的创建的pdf:
And with this code I can download a created pdf signed correctly:
private $tcpdf;
public function __construct(TCPDFController $tcpdf)
{
$this->tcpdf = $tcpdf;
}
public function aAction ()
{
$pdf = $this->tcpdf->create(
'LANDSCAPE',
PDF_UNIT,
PDF_PAGE_FORMAT,
true,
'UTF-8',
false
);
$pdf->SetAuthor('qweqwe');
$pdf->SetTitle('Prueba TCPDF');
$pdf->SetSubject('Your client');
$pdf->SetKeywords('TCPDF, PDF, example, test, guide');
$pdf->setFontSubsetting(true);
// set additional information
$info = array(
'Name' => 'xxx',
'Location' => 'xxx',
'Reason' => 'xxx xxxx',
'ContactInfo' => 'http://www.xxx.xx',
);
// set document signature
$pdf->setSignature('file:///var/www/html/publicCert.pem', 'file:///var/www/html/privateKey_cert.pem', 'xxxx', '', 2, $info, 'A');
$pdf->SetFont('helvetica', '', 11, '', true);
$pdf->AddPage();
$html = '<h1>Working on Symfony</h1>';
$pdf->writeHTMLCell(
$w = 0,
$h = 0,
$x = '',
$y = '',
$html,
$border = 0,
$ln = 1,
$fill = 0,
$reseth = true,
$align = '',
$autopadding = true
);
$pdf->Output("example.pdf", 'I');
}
我的目标是尝试对现有的pdf进行签名,所以我尝试使用FPDI导入它,但是我感到困惑,因为我知道我可以使用PDFI导入pdf,但是我无法对其进行签名,而使用TCPDF则相反,我无法导入pdf,但可以对已创建的pdf进行签名.而且显然我不能使用一个函数.
My objective is try to sign an existing pdf, so I tried to use FPDI to import it but I get confused because I know I can import a pdf with PDFI but I can't sign it and the opposite with the TCPDF, I can't import the pdf but I can sign a created one. And apparently I can't use functions from one to the other.
那么,我该如何解决此问题?任何的想法?你能给我举个例子吗?
So, how I should fix this problem? Any idea? Could you show me an example?
推荐答案
最后,我无法使用TCPDF捆绑包解决此问题,但我发现一个不太昂贵的解决方案抛出SetAsign,在此示例中您可以看到可以选择您要签名的pdf文件.我知道它要花钱,但是FPDI和这个库我可以看到pdfs的最新版本存在一些问题,而Setasign与FPDF插件相比是一个更稳定和维护的版本,将为您避免一些问题.
Finally I couldn't solve this problem with the TCPDF bundle but I found a not too much expensive solution throw SetAsign where in this example you can see that you can select the pdf you want to sign it. I know it cost a price but FPDI and this libraries I could see that got some problems with the newest versions from the pdfs and Setasign is a more stable and maintained version compared with FPDF pluggins and will avoid a few problems for you.
