在 DOMpdf 目录之外使用 DOM PDF 创建 pdf

Question

您好，我的网站上安装了 mybb。我还安装了 dompdf 并且它在它自己的目录中工作，即我已经安装在 "DOM" 目录中。现在我可以用这个简单的代码轻松地通用 pdf，保存在 "DOM" 目录中。

<?php
require_once "dompdf_config.inc.php";
//$file = "www/test/css_at_font_face.html"; 
$file="msf.html";
$dompdf = new DOMPDF();
$dompdf->load_html_file($file);
$dompdf->render();
$dompdf->stream("sample.pdf");

?>

如果我尝试访问导演之外的其他文件 DOM 即

load_html_file($file); $dompdf->渲染（）； $dompdf->stream("sample.pdf");

?> 我收到错误Remote file requested, but DOMPDF_ENABLE_REMOTE is false

Answer 1

为了启用远程访问不要编辑“dompdf_config.inc.php”

改用：

$dompdf = new DOMPDF();
$dompdf->set_option('enable_remote', TRUE);

$dompdf->set_option('enable_css_float', TRUE);
$dompdf->set_option('enable_html5_parser', FALSE);

Answer 2

在不启用远程文件访问的情况下加载 html：

<?php
require_once "dompdf_config.inc.php";
$file = "www/test/css_at_font_face.html"; 
$html=file_get_contents($file);
$dompdf = new DOMPDF();
$dompdf->load_html($html);
$dompdf->render();
$dompdf->stream("sample.pdf");

?>

启用远程文件访问：

取自 dompdf_config.inc.php

/**
 * Enable remote file access
 *
 * If this setting is set to true, DOMPDF will access remote sites for
 * images and CSS files as required.
 * This is required for part of test case www/test/image_variants.html through www/examples.php
 *
 * Attention!
 * **This can be a security risk**, in particular in combination with DOMPDF_ENABLE_PHP and
 * allowing remote access to dompdf.php or on allowing remote html code to be passed to
 * $dompdf = new DOMPDF(); $dompdf->load_html(...);
 * This allows anonymous users to download legally doubtful internet content which on
 * tracing back appears to being downloaded by your server, or allows malicious php code
 * in remote html pages to be executed by your server with your account privileges.
 *
 * @var bool
