WkHTMLtoPDF不加载本地CSS和图像 [英] WkHTMLtoPDF not loading local CSS and images

问题描述

我看到过很多与这个问题非常相似的问题，所以我一开始就很犹豫。但没有任何建议解决了我的问题，我似乎无法弄清楚自己有什么问题。

对于我为一个客户制作的项目，他们希望能够将报价转换为他们的客户（使用在线表单生成）到PDF。够简单。由于整个项目都在PHP中，我使用了以下简单的过程：
$ b

1. 将报价保存为临时HTML文件


2. 使用WkHTMLtoPDF将HTML文件转换为PDF


3. 输出此PDF文件
   
4. 清理（删除临时文件） / li>
   

直到他们更换服务器为止。新服务器有一个防火墙。

起初PDF转换步骤是返回一个防火墙页面，表示服务器无法建立出站连接。为了解决这个问题，我直接提供了HTML文件，而不是链接到它（/var/www/mysite/temp/18382.html而不是www.example.com/temp/18382.html）。这转换了HTML，但防火墙阻止了CSS和图片的加载。

我可以通过直接将它嵌入到站点而不是链接到它来使用CSS < style> 标记），但这对图像无效

我首先尝试使用相对链接。我将< img src =http://www.example.com/temp/image.jpg/> 更改为< img src =./ image.jpg/> 。这是行不通的。

接下来我尝试了< img src =file：/// var / www / mysite / temp / image .jpg/> 但这不起作用，要么

我仔细阅读并查看了WkHTMLtoPDF手册，并尝试了几种不同的方法命令行参数，如 - enable-local-file-access ， - 启用/ var / www / mysite / temp / 和 - images 但是没有任何东西可以修复它

解决方案

如果你在Linux上检查你的图像的所有权。对于Windows，您可以在 http://code.google.com/p/wkhtmltopdf/wiki/Usage 。

我尝试了不同类型的图片路径：

1. < img src =file：///var/www/testpdf/flowers.jpg>< br>


2. < img src =./ flowers.jpg>< br>


3. < img src =flowers.jpg>< br>


4. < img src =/ var / www / testpdf / flowers .jpg>< br>

所有图片都显示正确。我没有使用任何命令行参数
（仅 wkhtmltopdf /var/www/testpdf/makepdf.html makepdf.pdf ）

I've seen multiple questions that are very similar to this one, so I was hesitant at first to post it. But nothing suggested resolved my issue and I can't seem to figure out what's wrong myself.

For a project I made for one client they wanted to ability to convert quotes for their customers (generated using an online form) to PDFs. Simple enough. As the entire project was in PHP, I used the following simple process:

1. Save the quote as a temporary HTML file
2. Use WkHTMLtoPDF to convert the HTML file to a PDF
3. Output this PDF file
4. Clean up (delete temporary files)

This worked until they changed servers. The new server has a firewall.

At first the PDF conversion step was returning a firewall page saying that the server couldn't make outbound connections. To resolve this I fed the HTML file directly instead of linking to it (/var/www/mysite/temp/18382.html instead of www.example.com/temp/18382.html). This converted the HTML, but the firewall prevented the loading of CSS and images

I can overcome the CSS by simply embedding it directly in the site instead of linking to it (using the <style> tags), but this doesn't work for images

I tried using relative links first. I changed <img src="http://www.example.com/temp/image.jpg" /> to <img src="./image.jpg" />. This didn't work.

Next I tried <img src="file:///var/www/mysite/temp/image.jpg" /> but this didn't work, either

I read around and look through the WkHTMLtoPDF manual and I tried several different command line arguments like --enable-local-file-access, --enable /var/www/mysite/temp/, and --images but nothing seems to fix it

解决方案

If your are on linux check the ownership of your images. For windows you will find some info on http://code.google.com/p/wkhtmltopdf/wiki/Usage.

I tried different kind of paths to the image:

1. <img src="file:///var/www/testpdf/flowers.jpg"><br>
2. <img src="./flowers.jpg"><br>
3. <img src="flowers.jpg"><br>
4. <img src="/var/www/testpdf/flowers.jpg"><br>

all images are showed correct. I didn't use any command line arguments (only wkhtmltopdf /var/www/testpdf/makepdf.html makepdf.pdf)
