phpwkhtmltopdf -无法创建PDF -失败，没有错误消息

Question

尝试使用PHP和phpwkhtmltopdf包创建PDF

require '../vendor/autoload.php';
use mikehaertl\wkhtmlto\Pdf;

// You can pass a filename, a HTML string or an URL to the constructor
$pdf = new Pdf('http://www.google.co.uk');

// On some systems you may have to set the binary path.
//$pdf->binary = 'C:\pdf';

$pdf->send('google.pdf');
if (!$pdf->send()) {
    throw new Exception('Could not create PDF: '.$pdf->getError());
}

然而，得到的错误

Fatal error: Uncaught exception 'Exception' with message 'Could not create PDF: Failed without error message: wkhtmltopdf "http://google.com" "C:\Windows\Temp\tmp4047.tmp.pdf"' in C:\wamp\www\site\ajax\createpdf.php on line 24

​

​

转到c:\windows\temp，可以看到文件tmp4047.tmp.pdf -但已损坏，无法加载

我已经从命令行运行wkhtmltopdf，没有问题- PDF是正确创建的

 wkhtmltopdf http://google.com google.pdf

编辑-取而代之使用snappy -运行良好，有人在亚马逊网络服务弹性豆茎上使用过吗？有什么教程吗？TQ

//snappy
use Knp\Snappy\Pdf;
$snappy = new Pdf('C://"Program Files"/wkhtmltopdf/bin/wkhtmltopdf.exe');
header('Content-Type: application/pdf');
header('Content-Disposition: attachment; filename="file.pdf"');
echo $snappy->getOutput('http://www.google.co.uk');

注意- windows用户将引号放在"Program Files“周围

我在Windows和Apache上遇到了同样的问题，出现了同样的错误信息，我刚才修复了这个问题，在commandOptions上使用了'bypass_shell' => 'true';，并指定了指向您安装的wkhtmltopdf文件夹的二进制路径，通常在Program Files中。

工作代码：

$pdf = new Pdf([
                  'commandOptions' => [
                  'useExec' => false,
                  'escapeArgs' => false,
                  'procOptions' => array(
                  // This will bypass the cmd.exe which seems to be recommended on Windows
                  'bypass_shell' => true,
                 // Also worth a try if you get unexplainable errors
                  'suppress_errors' => true,
               ),
               ],
               ]);
               $globalOptions = array(
               'no-outline', // Make Chrome not complain
              // Default page options
               'page-size' => 'Letter'
                );

               $pdf->setOptions($globalOptions);
               $pdf->addPage('http://www.google.com');
               $pdf->binary = 'C:\Program Files\wkhtmltopdf\bin\wkhtmltopdf.exe';
               if (!$pdf->send()) {
            throw new Exception('Could not create PDF: '.$pdf->getError());
          }

如果将useExec命令参数设置为true，则应在二进制路径中为"Program Files“添加双引号，否则将出现错误C:\Program is not recognized as a internal or external command、operable program or batch File.感谢Mikehaertl的有用文档和wkhtmltopdf的出色工作。干杯!
