python无法在imagemagick策略中通过https打开文件错误

我正在使用imagemagicpythonlib打开远程文件（pdf），但出现了错误

如果我使用带有http的链接，它工作正常，但是使用https我会得到如下错误

wand.exceptions.**PolicyError**: not authorized `HTTPS' @ error/delegate.c/InvokeDelegate/1717

我编辑了我的https无策略以阅读

下面是策略在Ubuntu中的图像魔术库

  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="read" 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/*" />

  Let's prevent possible exploits by removing the right to use indirect reads.

    <policy domain="path" rights="read" pattern="@*" />

  Any large image is cached to disk rather than memory:

    <policy domain="resource" name="area" value="1GB"/>

  Define arguments for the memory, map, area, width, height, 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).

此库是否只支持http文件而不支持https？

您有

，它应该允许您通过https进行读取。确保查看的是policy.xml文件的正确版本。有关可能的位置，请参阅。还要确保Wand可以访问正确的policy.xml文件。我不是Wand方面的专家，不知道它如何或是否使用policy.xml文件。您有
