【问题描述】：
我正在尝试在 Windows 7 64 位上运行的 CodeIgniter 上使用 DOMPDF 版本 0.8 将 HTML 页面呈现为 PDF。我的开发机器在 Windows 10 Pro 上的 XAMPP 上运行 PHP 7，但生产服务器在 Windows 7 Professional 64 位上运行 PHP 5.6。
我意识到，当我在本地计算机上运行应用程序时，一切正常，并且正确生成了 PDF，图像和样式正确显示在适当的位置。但是当我部署到生产机器时，样式和图像不能再次正确渲染。图像不显示，样式不渲染。
如果有任何解决此问题的建议，我将不胜感激
下面是我的部分代码：
//应用程序/库/pdf.php
<?php
defined('BASEPATH') OR exit('No direct script access allowed');
require_once("./vendor/dompdf/dompdf/src/autoloader.php");
use Dompdf\Dompdf;
class Pdf
{
public function generate($html, $filename='', $stream=TRUE, $paper = 'A4',
$orientation = "landscape")
{
$dompdf = new DOMPDF();
$dompdf->loadHtml($html);
$dompdf->setPaper($paper, $orientation);
$dompdf->render();
if ($stream)
{
$dompdf->stream($filename.".pdf", array("Attachment" => 1));
}
else
{
return $dompdf->output();
}
}
}
//Application/controllers/report.php
...some code removed for brevity
$this->load->library('pdf');
$html=$this->load->view('parts/pdf-head',NULL,true);
$html.=$this->load->view('admin/reports/periodic/pdf',['results'=>$_SESSION['students_result']],true);
$this->pdf->generate($html,'report');
//Application/views/admin/reports/periodic/pdf.php
<?php

【问题讨论】：
-
您在哪台服务器上托管您的网站（Apache 或 IIS）？
-
@Ganesh Aher 两台机器都在 Apache 上运行。我实际上在两台机器上都使用 XAMPP
-
检查你的配置文件中的 base_url 和 .htaccess 文件
-
@Ganesh Aher 请解释一下。哪个配置文件以及 base_url 和 .htaccess 应该是什么样的？
