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. Among the following codes provided as the guide, file upload part is a sample code and has insufficient security. As for the file upload, please use the code used within your project and refer the following code to handle the system link. |

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 |
