carrierwave设置CONTENT_TYPE不正确 [英] carrierwave setting content_type incorrectly
本文介绍了carrierwave设置CONTENT_TYPE不正确的处理方法，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
我使用Carrierwave雾存储在我的Rails应用程序，而我使用的Carrierwave-Video和Carrierwave视频 - thumbnailer的宝石，使视频从上传视频上传和缩略图创造。
当我上传的MP4文件，我希望它到C是跨$ C $到MP4中，创建一个WEBM版本，并创建两个不同大小的缩略图文件（.png）。现在，所有的文件都成功上传到Amazon S3，但内容类型是越来越处理视频/ QuickTime的所有文件。这是对我造成一个问题，因为我想使用HTML 5视频标签播放WEBM文件在Firefox，它是不能够因为视频的内容类型，以发挥他们被设置为视频/ QuickTime的，而不是视频/ WEBM。
这是我上传的文件， video_path_uploader.rb

解决方案
我忘了更新我的答案，这一次我想出了一个办法手动设置内容类型。这是我落得这样做：
要求carrierwave /处理/ mime_types
类VideoPathUploader＆LT; CarrierWave ::上传::基地
包括CarrierWave :: MIMETYPES
过程：恩code
DEF EN code
视频= MiniExiftool.new（@ file.path）
方向= video.rotation
model.rotation =方向
Rails.logger.debug（方向：＃{}方向）
Rails.logger.debug（视频宽x高＃{video.imagewidth}＃{video.imageheight}）
如果方向== 90安培;＆安培; video.imagewidth.to_f＆GT; video.imageheight.to_f
Rails.logger.debug（旋转视频）
aspect_ratio = video.imageheight.to_f / video.imagewidth.to_f
EN code_video（：MP4，自定义：-vf转= 1，分辨率：同样的，纵横：aspect_ratio）
其他
aspect_ratio = video.imagewidth.to_f / video.imageheight.to_f
EN code_video（：MP4，分辨率：同样的，纵横：aspect_ratio）
结束
instance_variable_set（：@ CONTENT_TYPE，视频/ MP4）
：set_content_type_mp4
结束
版本：WEBM做
过程：恩code_video =＆GT; [：WEBM]
过程：set_content_type_webm
高清full_filename（for_file）
＃{File.basename（for_file，File.extname（for_file））}。WEBM
结束

高清set_content_type_mp4（*参数）

希望这可以帮助别人！
I am using Carrierwave with fog storage in my Rails app, and I'm using the Carrierwave-Video and Carrierwave-Video-Thumbnailer gems to enable video uploading and thumbnail creation from the uploaded video.
When I upload an mp4 file, I expect it to transcode it to mp4, create a webm version, and create two differently-sized thumbnail images (.png). Right now, all the files are successfully uploaded to Amazon S3, but the content-type is getting processed as video/quicktime for all files. This is causing an issue for me because I want to play webm files in Firefox using the HTML 5 Video tag, and it's not able to play them since the content type of the video is set to video/quicktime rather than video/webm.
This is my uploader file, video_path_uploader.rb
require 'carrierwave/processing/mime_types'
class VideoPathUploader < CarrierWave::Uploader::Base
include CarrierWave::Video
include CarrierWave::Video::Thumbnailer
include CarrierWave::MimeTypes
# Include RMagick or MiniMagick support:
# include CarrierWave::RMagick

# 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
"#{model.class.to_s.underscore}/#{mounted_as}/#{model.id}"
end
process encode_video: [:mp4]
process :set_content_type
def filename
result = [original_filename.gsub(/\.\w+$/, ""), 'mp4'].join('.') if original_filename
result
end
version :webm do
process :encode_video => [:webm]
process :set_content_type
def full_filename(for_file)
"#{File.basename(for_file, File.extname(for_file))}.webm"
end
end
version :thumb do
process thumbnail: [{format: 'png', quality: 10, size: 158, logger: Rails.logger}]
def full_filename for_file
png_name for_file, version_name
end
process :set_content_type
# process resize_to_limit: [105, 158]
end
version :square_thumb do
process thumbnail: [{format: 'png', quality: 10, size: 105, strip: false, logger: Rails.logger}]
def full_filename for_file
png_name for_file, version_name
end
process :set_content_type
# process resize_to_fill: [105, 105]
end
def png_name for_file, version_name
%Q{#{version_name}_#{for_file.chomp(File.extname(for_file))}.png}
end
end

Rendered images/create.js.erb (12.3ms)
Completed 200 OK in 13069.3ms (Views: 15.3ms | ActiveRecord: 64.6ms)
And this is what is rendered on my page:
<video controls>
<source src="https://...s3.amazonaws.com/video/video_path/158/Untitled.webm" class="348" id="video_348" type="video/webm">
<source src="https://...s3.amazonaws.com/video/video_path/158/Untitled.mp4" class="348" id="video_348" type="video/mp4">
</video>

I forgot to update my answer to this once I figured out a way to manually set the content type. This is what I ended up doing:
require 'carrierwave/processing/mime_types'
class VideoPathUploader < CarrierWave::Uploader::Base
include CarrierWave::MimeTypes
process :encode
def encode
video = MiniExiftool.new(@file.path)
orientation = video.rotation
model.rotation = orientation
Rails.logger.debug("orientation: #{orientation}")
Rails.logger.debug("video wxh #{video.imagewidth} #{video.imageheight}")
if orientation == 90 && video.imagewidth.to_f > video.imageheight.to_f
Rails.logger.debug("rotating video")
aspect_ratio = video.imageheight.to_f / video.imagewidth.to_f
encode_video(:mp4, custom: "-vf transpose=1", resolution: :same, aspect: aspect_ratio)
else
aspect_ratio = video.imagewidth.to_f / video.imageheight.to_f
encode_video(:mp4, resolution: :same, aspect: aspect_ratio)
end
instance_variable_set(:@content_type, "video/mp4")
:set_content_type_mp4
end
version :webm do
process :encode_video => [:webm]
process :set_content_type_webm
def full_filename(for_file)
"#{File.basename(for_file, File.extname(for_file))}.webm"
end
end
def set_content_type_mp4(*args)
Rails.logger.debug "#{file.content_type}"
self.file.instance_variable_set(:@content_type, "video/mp4")
end
def set_content_type_webm(*args)
Rails.logger.debug "#{file.content_type}"
self.file.instance_variable_set(:@content_type, "video/webm")
end
end
Hope this helps someone!
