imagemagick - 在heroku上更改policy.xml [英] imagemagick - change policy.xml on heroku

问题描述

我试图通过https与heroma上的imagemagick访问图像。如何更改heroku上的策略（在policy.xml中）？

heroku在2016年5月发布了ImageMagick安全更新：

我可以在输入 heroku run bash 和 convert -list policy 后看到策略列表：

路径：[内置]
策略：未定义
权限：无


路径：/etc/ImageMagick/policy.xml
[...]
策略：编码器
权利：无
模式：HTTPS
[...]


我该如何更改政策？

更新1：这是日志文件中的错误：

命令失败：convert.im6：not authorized`//scontent-fra3-1.xx.fbcdn.net/v/t1.0-9/13962741_132344500547278_4974691444630710043_n.jpg?oh=c169b4ffce9e5ce330ee99214cc6b8d5&oe = 5880F245'

解决方案

我们需要在heroku上安装第三方软件ImageMagick。我使用了 https://github.com/ello/heroku-buildpack-imagemagick 用于安装ImageMagick的构建包。

因此，在bin / compile中，有一个策略文件限制图片通过Https读取，启用属性 rights 至读，允许读取Https

分叉回购并进行更改，提交并将该存储库url添加到您的heroku buildpack中。

I'm trying to access images via https on heroku with imagemagick. How can I change the policies (in policy.xml) on heroku?

heroku made an "ImageMagick security update" in May, 2016: https://devcenter.heroku.com/changelog-items/891

I can see the policy list, after typing heroku run bash and convert -list policy:

Path: [built-in] Policy: Undefined rights: None

Path: /etc/ImageMagick/policy.xml [...] Policy: Coder rights: None pattern: HTTPS [...]

How can I change the policy?

update 1: this is the error in the log file:

Command failed: convert.im6: not authorized `//scontent-fra3-1.xx.fbcdn.net/v/t1.0-9/13962741_132344500547278_4974691444630710043_n.jpg?oh=c169b4ffce9e5ce330ee99214cc6b8d5&oe=5880F245'

解决方案

We need to install the third party software ImageMagick on heroku. I used this https://github.com/ello/heroku-buildpack-imagemagick build pack for installing ImageMagick.

So, inside bin/compile, there is a policy file, which is restricting the images to read over Https, enable the attribute rights to read which allows to read over Https

Fork the repo and do your changes, commit and add that repository url to your heroku buildpacks
