从PHP执行Puppeteer时出错 [英] Error executing Puppeteer from PHP

问题描述

我有一个节点脚本，可以将网页转换为PDF文档.用户输入一些内容，然后PHP构建一个HTML页面，然后将其用于节点脚本(运行Puppeteer，使用示例脚本)将其转换为PDF.

I have a node script which converts a webpage into a PDF document. The user enters some content and PHP builds a HTML page, which then is used in a node script (that runs Puppeteer, using a slightly modified version of an example script) to convert it to PDF.

但是当我在PHP中 exec 时，该命令将运行节点脚本，它失败并显示以下错误:

But when I exec in PHP the command to run the node script, it fails with the following error:

(node:14832) UnhandledPromiseRejectionWarning: Error: Failed to launch chrome!

PHP正在使用apache用户运行.但是，如果我与用户一起运行相同的脚本，则可以完美运行.当我在终端中使用su - apache -c 'node ...'执行时，它再次引发上述错误.

PHP is running with the apache user. However, if I run the same script with my user, it works perfectly. When I execute in a terminal using su - apache -c 'node ...' it again throws the error described above.

是什么原因导致错误?与apache用户的权限有关吗?我已经遵循了所有麻烦提示指南，但此刻我还没有运气.

What is causing the error? Something related to apache user's permissions? I've followed all troubleshotting guides but I had no luck at the moment.

推荐答案

该问题似乎来自于操纵up使用的默认铬的文件系统权限:

The problem seems to come from the file-system permissions on the default chromium used by puppeteer:

使用ACL(我的nginx组是www-data，请根据您的要求更改Apache):

using ACL( my nginx group is www-data, change with yours for apache):

sudo setfacl -R -m g:www-data:rX node_modules/puppeteer/.local-chromium/

和

sudo setfacl -dR -m g:www-data:rX node_modules/puppeteer/.local-chromium/

设置权限后，错误消失了.

after setting the permissions the error went away.
