使用 dompdf 创建 pdf 文件时，不会将图像添加到 pdf 文件中

  • 772

这样的问题，你需要创建一个html页面，显示给用户，并以pdf的形式保存在服务器上。对于这个任务，我使用 dompdf。文字和表格显示正确，但是图片有问题： 在此处输入图像描述

页面代码：

     <meta charset="UTF-8">
<!DOCTYPE html>
<html lang="en">
<?php
    ob_start();
?>
<?php 
       $path = 'http://localhost/object_calculator/header.jpg';
$type = pathinfo($path, PATHINFO_EXTENSION);
$data = file_get_contents($path);
$base64 = 'data:image/' . $type . ';base64,' . base64_encode($data);
       ?>
<head>
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <script type="text/javascript" src="js/script.js"></script>
    <title>Document</title>


</head>
<body>
   <div class="list_1">
      <header>
        <img style="width:100%; height:387px"alt="" src=<?php echo $base64 ?>>
    </header>
    <div class="middle">
      <h1 style="margin-left:4.5%">Коммерческие условия поставки:</h1>
        <br>

  <footer>
    <img src="img/footer.jpg" style="width:90%; margin-left: 4.5%;" alt="">
  </footer>
</div> 
</body>
<?php
  require_once "dompdf/dompdf_config.inc.php";
  $dompdf = new DOMPDF();
  $my_html =  ob_get_clean();
  echo $my_html;
  $dompdf->load_html($my_html);
  $dompdf->render();
  $output = $dompdf->output();
  file_put_contents("file.pdf", $output);

?>
</html>

可能是什么问题以及如何解决？我尝试使用base64，并且规定了完整路径

    我必须下载 dompdf 0.8.0 的早期版本

    <?php
      $image = 'header.jpg';
      $imageData = base64_encode(file_get_contents($image));
      $src = 'data:'.mime_content_type($image).';base64,'.$imageData;
      $my_html =  '
