载波将文件编码为base64作为进程 [英] Carrierwave encode file to base64 as process
本文介绍了载波将文件编码为base64作为进程的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我正在尝试解决这个问题.我想将文件编码为base64作为该过程之一.
I am trying to solve this. I would like to encode file as base64 as one of the process.
到目前为止,我的代码看起来像
My code so far looks like
class ImageUploader < CarrierWave::Uploader::Base
include CarrierWave::MiniMagick
include CarrierWave::MimeTypes
storage :file
def extension_white_list
%w(jpg jpeg png)
end
def store_dir
"/tmp/images/#{model.class.to_s.underscore}/#{model.id}"
end
process :set_content_type
process :format_to_jpg
process :strip_metadata
process :encode_base64
def format_to_jpg
manipulate! do |img|
img.format 'jpg'
img
end
end
def strip_metadata
manipulate! do |img|
img.strip
img
end
end
def encode_base64
#What should be here?
end
end
我不确定应该在encode_base64方法中放置什么.编码方法是Base64.encode64(),因为应该将文件内容(可能是self.read)发送给参数.但是我不确定如何遵循Carrierwave的最佳做法.
I am not sure what I should place in the encode_base64 method. The method for encoding is Base64.encode64() as parameter should be sent the file content (self.read probably). but I am not sure how I should do this to follow Carrierwave best practices.
推荐答案
发现我在这里不需要做任何特别的事情.
Find out that I don't have to do anything special here.
def encode_base64
File.write(path,Base64.encode64(File.read(path)))
end
