Question

我正在使用名为rubypress的gem来使用XMLRPC将ruby中的内容发布到wordpress。除图像上传部分外，一切正常。我将图像转换为base64编码格式，但在上传后，我得到的只是灰色图像，而不是我打算上传的图像（我使用大约100kb大小的较小图像上传进行测试）。我做错了什么？以下是来自rubypress github页面（https://github.com/zachfeldman/rubypress）的代码，用于上传：

FILENAME='myFile.png'
wp.uploadFile(:data => {
    :name => FILENAME,
    :type => MIME::Types.type_for(FILENAME).first.to_s,
    :bits => XMLRPC::Base64.new(IO.read(FILENAME))
    })

Answer 1

尝试：

wp.uploadFile(:data => {:name => File.basename(FILENAME),
                   :type => MIME::Types.type_for(FILENAME).first.to_s,
                   :bits => XMLRPC::Base64.new(File.open(FILENAME).read)
})

Answer 2

我终于能够通过更改Base64编码代码来解决它：

$wp.uploadFile(:data => {
    :name => File.basename(imgname),
    :type => MIME::Types.type_for(imgname).first.to_s,
    :bits => XMLRPC::Base64.new(File.open(FILENAME,"rb").read),
    :post_id =>postid

    })

该文件显然需要首先“打开”，而不是使用IO.read（FILENAME）读取。

这是我的做法，效果很好：

image = MiniMagick::Image.open(this_image.path)
image.format('jpg')
image.combine_options do |c|
  c.strip
end
image.write(this_image.path)

# most efficient resize as suggested by https://www.smashingmagazine.com/2015/06/efficient-image-resizing-with-imagemagick/
MiniMagick::Tool::Mogrify.new do |mogrify|
  mogrify.filter('Triangle')
  mogrify.define('filter:support=2')
  mogrify.thumbnail('960x')
  mogrify.unsharp('0.25x0.08+8.3+0.045')
  mogrify.dither('None')
  mogrify.posterize('136')
  mogrify.quality('82')
  mogrify.define('jpeg:fancy-upsampling=off')
  mogrify.interlace('none')
  mogrify.colorspace('sRGB')
  mogrify << this_image.path
end


type = image.mime_type
bits = XMLRPC::Base64.new(IO.read(this_image.path))

begin
  result = wp.uploadFile(
           data: {
               name: image_name,
               type: type,
               bits: bits,
               post_id: post_id,
               overwrite: true
           })
rescue StandardError => e 
  puts e
end

无法使用XMLRPC将图像从Ruby上传到Wordpress - 损坏的图像
