如何将生成的javascript pdf文件保存到我服务器的文件系统中?

标签: javascript php pdfmake

我正在使用pdfmake创建我的pdf,虽然它允许用户直接打开pdf或将其下载到他们的计算机,但我不确定如何生成pdf并将其保存到我的服务器文件中系统

据我所知,有很多安全措施不允许javascript将数据保存到文件中,所以将它发送到我的php后端是唯一的选择吗?我将如何做到这一点?

谢谢!

PHP:

<?
// pull the raw binary data from the POST array
$data = substr($_POST['data'], strpos($_POST['data'], ",") + 1);
// decode it
$decodedData = base64_decode($data);
// print out the raw data, 
echo ($decodedData);
$filename = "test.pdf";
// write the data out to the file
$fp = fopen($filename, 'wb');
fwrite($fp, $decodedData);
fclose($fp);
?>

JS:

var docDefinition = {
  content: 'This is an sample PDF printed with pdfMake'
};

pdfMake.createPdf(docDefinition).getBuffer(function(buffer) {
  var blob = new Blob([buffer]);

  var reader = new FileReader();
  // this function is triggered once a call to readAsDataURL returns
  reader.onload = function(event) {
    var fd = new FormData();
    fd.append('fname', 'test.pdf');
    fd.append('data', event.target.result);
    $.ajax({
      type: 'POST',
      url: 'upload.php', // Change to PHP filename
      data: fd,
      processData: false,
      contentType: false
    }).done(function(data) {
      // print the output from the upload.php script
      console.log(data);
    });
  };
  // trigger the read from the reader...
  reader.readAsDataURL(blob);
});
