Imagick - ImagickException未授权@ error /Constructe.c/ReadImage/412错误
提问于 2018-10-15 21:20:55
我正在尝试将一个pdf文件加载到imagick中，但是我得到了以下结果：
(1/1) ImagickException
not authorized `/var/sample.pdf' @ error/constitute.c/ReadImage/412我使用了以下代码：
$imagick = new Imagick( '/var/sample.pdf' );Imagick一直适用于我，但在更新它之后，在任何地方的任何文件上都会发生这种异常。该文件的权限为777。我使用的是Ubuntu Server 16.04 LTE。
有人知道怎么解决这个问题吗？

sudo -s (or su -)
apt install ghostscript -y
ln -s /usr/local/bin/gs /usr/bin/gs
cp /etc/ImageMagick-6/policy.xml /etc/ImageMagick-6/policy.xml.bak
sed -i "s/rights\=\"none\" pattern\=\"PS\"/rights\=\"read\|write\" pattern\=\"PS\"/" /etc/ImageMagick-6/policy.xml
sed -i "s/rights\=\"none\" pattern\=\"EPI\"/rights\=\"read\|write\" pattern\=\"EPI\"/" /etc/ImageMagick-6/policy.xml

sed -i "s/rights\=\"none\" pattern\=\"XPS\"/rights\=\"read\|write\" pattern\=\"XPS\"/" /etc/ImageMagick-6/policy.xml
service php7.2-fpm restart && service nginx restart我今晚就想明白了。由于我已经升级了我的Ubuntu，imagick安装了一个新的policy.xml文件，它不允许我打开那个.pdf文件。
您必须在policy.xml中设置正确的权限，才能正确打开文件。
policy.xml位置(Unix)
/etc/ImageMagick-6/policy.xml新的编码器(domain=“编码器”部分是我配置的)。
<?xml version="1.0" encoding="UTF-8"?>

<!--
Configure ImageMagick policies.
Domains include system, delegate, coder, filter, path, or resource.
Rights include none, read, write, and execute. Use | to combine them,
for example: "read | write" to permit read from, or write to, a path.
Use a glob expression as a pattern.
Suppose we do not want users to process MPEG video images:
<policy domain="delegate" rights="none" pattern="mpeg:decode" />
Here we do not want users reading images from HTTP:
<policy domain="coder" rights="none" pattern="HTTP" />
Lets prevent users from executing any image filters:
<policy domain="filter" rights="none" pattern="*" />
The /repository file system is restricted to read only. We use a glob
expression to match all paths that start with /repository:
<policy domain="path" rights="read" pattern="/repository/*" />
Any large image is cached to disk rather than memory:
<policy domain="resource" name="area" value="1GB"/>
Define arguments for the memory, map, area, and disk resources with
SI prefixes (.e.g 100MB). In addition, resource policies are maximums for
each instance of ImageMagick (e.g. policy memory limit 1GB, -limit 2GB
exceeds policy maximum so memory limit is 1GB).

在PHP中使用以下代码设置临时路径：
$i = new Imagick();
$i->setRegistry('temporary-path', '/efs');Stack Overflow用户

使用以下命令删除策略文件以修复该问题。
rm /etc/<ImageMagick_PATH>/policy.xml对于我来说，它是ImageMagick6，命令是：
