【问题描述】:
我正在使用 CarrierWave 在我的应用程序中上传文件。自 2018 年 10 月 6 日起,突然无法上传 pdf 文件,应用程序引发此错误:
Failed to manipulate with MiniMagick, maybe it is not an image? Original Error:
`identify /tmp/mini_magick20181010-10534-s5jchg.pdf` failed with error:
identify: not authorized `/tmp/mini_magick20181010-10534-s5jchg.pdf' @
error/constitute.c/ReadImage/412.
同样有很多问题,但没有一个答案能解决这个问题。我也尝试过使用 Rmagick,但没有运气。
下面是我的上传器设置
class AttachmentUploader < CarrierWave::Uploader::Base
# Include RMagick or MiniMagick support:
# include CarrierWave::RMagick
include CarrierWave::MiniMagick
# Choose what kind of storage to use for this uploader:
#storage :file
storage :fog
# Override the directory where uploaded files will be stored.
# This is a sensible default for uploaders that are meant to be mounted:
def store_dir
"uploads/#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
# Provide a default URL as a default if there hasn't been a file uploaded:
def default_url
"no-photo.png"
end
# Create different versions of your uploaded files:
version :thumb do
# crop to exactly 80px x 80px
process :resize_to_fill => [80, 80]
end
version :web do
# scale to be no larger than 800px x 500px
process :resize_to_limit => [800, 500]
end
# Add a white list of extensions which are allowed to be uploaded.
# For images you might use something like this:
# def extension_white_list
# %w(jpg jpeg gif png)
# end
# Override the filename of the uploaded files:
# Avoid using model.id or version_name here, see uploader/store.rb for details.
# def filename
# "something.jpg" if original_filename
# end
end
让我知道你的想法。
谢谢
【问题讨论】:
-
不适用于 pdf,因为您的上传器的操纵器是专门为图像设计的,它们不能用于 pdf?
-
在
version :thumb和version :web之后添加, :if => :image?? -
是的,我同意我已经进行了这些更改,但我想知道以前是如何工作的。
-
也许版本更新了,他们以前处理过这样的事情?不确定
-
希望您正在使用 git 版本控制并且可以看到您的代码中可能发生了什么变化?你找到解决办法了吗?你可能不需要
CarrierWave::MiniMagick是否尝试将其注释掉?
