가이드로 제공되는 아래 코드 중 파일 업로드 부분은 샘플 코드로서 보안 관련 처리가 미흡합니다. 파일 업로드 부분은 프로젝트 내부에서 사용하시는 부분을 그대로 사용하시고 아래 코드를 참고하셔서 연동 부분을 처리해주세요. |

아래 예제에서는 이미지, 동영상, 파일 업로드에는 '/upload' API를, 임포트에는 '/import' API를 사용하였습니다.
Code Block | ||||||
---|---|---|---|---|---|---|

{
'editor.import.api': '/import',
'editor.upload.image.api': '/upload',
'editor.upload.video.api': '/upload',
'editor.upload.file.api': '/upload',

1. 파일 업로더 생성

Class FileUploader < 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/"
end
# Provide a default URL as a default if there hasn't been a file uploaded:
# def default_url(*args)
# # For Rails 3.1+ asset pipeline compatibility:
# # ActionController::Base.helpers.asset_path("fallback/" + [version_name, "default.png"].compact.join('_'))
#
# "/images/fallback/" + [version_name, "default.png"].compact.join('_')
# end
# Process files as they are uploaded:
# process scale: [200, 300]
#
# def scale(width, height)
# # do something
# end
# Create different versions of your uploaded files:
# version :thumb do
# process resize_to_fit: [50, 50]
# end
# Add a white list of extensions which are allowed to be uploaded.
# For images you might use something like this:
# def extension_whitelist
# %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
"#{secure_token}.#{file.extension}" if original_filename.present?
end
protected
def secure_token
var = :"@#{mounted_as}_secure_token"
model.instance_variable_get(var) or model.instance_variable_set(var, SecureRandom.uuid)
end
end |
2. 모델 생성
Code Block | ||
---|---|---|
| ||
> rails generate model UploadFile |
Code Block | ||||
---|---|---|---|---|
| ||||
class UploadFile < ApplicationRecord
mount_uploader :file, FileUploader
end |
3. 컨트롤러 생성
Code Block | ||
---|---|---|
| ||
> rails generate controller UploadFile |
Code Block | ||||
---|---|---|---|---|
| ||||
class UploadFileController < ApplicationController
skip_before_action :verify_authenticity_token # csrf_token
def upload
uploaded = UploadFile.create(file: params[:file])
render json:{
"uploadPath": uploaded.file.url
}
end
def import
root_path = Rails.root
uploaded = UploadFile.create(file: params[:file])
# 1. 문서 변환
input_file_path = uploaded.file.path
input_file_name = File.basename(input_file_path)
output_dir_name = File.basename(input_file_name, File.extname(input_file_name))
converter_path = "%s/sedocConverter/sedocConverter_exe" % [root_path]
font_dir_path = "%s/fonts" % [root_path]
output_dir_path = "%s/public/output/%s" % [root_path, output_dir_name]
tmp_dir_path = "%s/tmp" % [root_path]
system("%s -pz -f %s %s %s %s" % [converter_path, font_dir_path, input_file_path, output_dir_path, tmp_dir_path])
# 2. PB 데이터 직렬화
pb_file_path = "%s/document.pb" % [output_dir_path]
aFile = File.open(pb_file_path, "r")
aSerialized = Array.new
if aFile
aFile.sysread(16)
aFile.each_byte do |byte|
aSerialized.push(byte & 0xFF)
end
end
# 3. 불필요한 파일 삭제
File.delete(input_file_path) if File.exist?(input_file_path)
File.delete(pb_file_path) if File.exist?(pb_file_path)
render json: {
"importPath": "/output/%s" % [File.basename(output_dir_path)],
"serializedData": aSerialized
}
end
end
|
4. 데이터베이스 마이그레이션
Code Block | ||
---|---|---|
| ||
# UploadFile에 파일을 담을 'file' 필드 추가
> rails generate migration AddFileToUploadFile file:string
> rake db:migrate |
5. 라우터 연결
Code Block | ||||
---|---|---|---|---|
| ||||
Rails.application.routes.draw do
post 'import' => 'upload_file#import'
post 'upload' => 'upload_file#upload'
end |
