PHP 使用 wkhtmltopdf 的问题

[kkshell]

问题麻烦跳转看下 https://segmentfault.com/q/1010000020318067

搞了一早上没得头绪，求支招

wkhtmltopdf 0.12.1

问题已经解决，这个文档里面有提到一个问题，我尝试升级一下 wkhtmltopdf，然后就可以咯- -

https://github.com/KnpLabs/snappy/blob/master/doc/faq.md

Q: It says wkhtmltopdf: cannot connect to X server or xvfb-run: error: Xvfb failed to start.
A: Please, check your wkhtmltopdf version. It is recommended to use at least 0.12.2.1 and what is important - starting from wkhtmltopdf >= 0.12.2 it doesn't require X server or emulation anymore. You can download new version from http://wkhtmltopdf.org/downloads.html or install via composer for Linux servers as stated in README. If there is no possibility to update wkhtmltopdf, please check http://stackoverflow.com/questions/9604625/wkhtmltopdf-cannot-connect-to-x-server

youyou 会的大佬不

和 php 无关，wkhtmltopdf 需要启动图形界面，你可以借助 xvfb 封装一个无界面的命令行

具体可以参考我以前写过的一个 wkhtmltopdf 微服务 dockerfile

[kkshell]

@AlloVince 好的谢谢，我参考一下

[manhere]

可以 composer require "knplabs/knp-snappy"

[kkshell]

@manhere 有什么作用

[manhere]

@kkshell https://github.com/KnpLabs/snappy 一直使用，没有问题

[gamesme]

虽然我是个小白 但是有看过一个 laravel 项目使用 wkhtmltopdf 项目叫 Bookstackapp 里面也是用楼上提到的 knpsnappy 包来调用 wkhtmltopdf
具体代码我就看不懂了 不知道能不能帮到你

[gamesme]

好像不是用 exec 是用 proc_open 执行

[kkshell]

@manhere
$snappy = new Pdf('/usr/bin/wkhtmltopdf');
$snappy->generateFromHtml($content, '/tmp/bill-123.pdf');

问题依旧如下：The exit status code '1' says something went wrong:
stderr: "wkhtmltopdf: cannot connect to X server
"
stdout: ""
command: /usr/bin/wkhtmltopdf --lowquality '/tmp/knp_snappy5d735f969db923.75691036.html' '/tmp/bill-123.pdf'.

[kkshell]

@gamesme 嗯，但是还是有这个问题 wkhtmltopdf: cannot connect to X server

[kkshell]

@AlloVince 网站无法访问

[sleepm]

你把它整复杂了
exec 直接调用 wkhtmltopdf 完了，要啥 xserver

[kkshell]

@sleepm 直接调用就是报这个错 string(41) "wkhtmltopdf: cannot connect to X server"

[gamesme]

目前为止我觉得二楼的回答是最靠谱的
For CentOS PHP environment the WkHTMLtoPDF tool not need xvfb-run to exec the command, But for Ubuntu PHP environment need xvfb-run to exec the command! I had revised my code as below and the issues was resolved

这是楼主您在 segmentfault 贴的解决办法链接，错误出现的原因应该是 Ubuntu 需要图形界面来运行 wkhtmltopdf

[wangyongbo]

你可以尝试升级到这个版本。wkhtmltopdf 0.12.4 (with patched qt)

我在 python 里面用的这个版本。 运行正常。

[zjsxwc]

基于 Qt Webkit 的工具你想不依赖 x server 就能运行？

借帖子问一下，我用 python 写了一个 markdown 转 pdf，表格渲染不出来怎么解决呢

[linxiaojialin]

Laravel:

# config/snappy.php
return [
'pdf' => array(
'enabled' => true,
'binary' => '/usr/local/bin/wkhtmltopdf',
'timeout' => false,
'options' => [],
'env' => [],
),
'image' => array(
'enabled' => true,
'binary' => '/usr/local/bin/wkhtmltoimage',
'timeout' => false,
'options' => [],
'env' => [],
),
];

# Controller@method:
$snappy = resolve('snappy.image.wrapper');
return $snappy->getOutput($url);

这个玩意需要 x 桌面环境，也就是图形化处理；这个没办法，我记得蚂蚁笔记服务器部署也有这个，一安装这个划拉一堆 X 桌面环境
