API Movie With Google Drive Link

With this article, I want to show you guy about the secret of google drive link video, It has been used by many website movies include phimmoi, moviehdkh, kisscartoon or xmovies8. They already use that technology to get link video from google drive by PHP, ASP.net. Now I will show you guy how to use Ruby on Rails to get that links.

We will start with a simple rails application as below.

Create the Rails App

Type the following at the command prompt:

$ rails new api-gdrive-video
$ cd api-gdrive-video
$ bundle

Create the Movies Controller

Create the movies controller using the Rails generator, add routes to config/routes.rb, and add methods for showing, creating, and listing movies.

$ rails g controller movies

Then open config/routes.rb and add this resource:

Rails.application.routes.draw do
  root "movies#index"
  resources :movies, only: [:index, :create]
end

To get links video from google drive video file we need to use one gem that it is called Mechanize. It allows us to get file from url of links video google drive. Let's add gem 'mechanize' into file GemFile and run bundle install.

Class logic

Now, we need to create a file name app/logic/google_drive.rb. After that we fill the codes into that file as below:

class GoogleDrive
  class << self
    REDIRECT_URL = "https://redirector.googlevideo.com/videoplayback?"
    VIDEO_PLAYBACK = "com/videoplayback?"
    FMT_STREAM_MAP = "fmt_stream_map="
    FMT_LIST = "&fmt_list"
    DOC_GOOGLE = "docs.google.com/file/d/"
    MAIL = "https://mail.google.com/e/get_video_info?docid="
    ITAGS = [{label: "360", itag: "itag=18"}, {label: "480", itag: "itag=59"},
      {label: "720", itag: "itag=22"}, {label: "1080", itag: "itag=37"}]
    DRIVEID = "&driveid"

    # format url:
    # https://docs.google.com/file/d/{file_id}/view
    # https://docs.google.com/file/d/{file_id}/preview
    # https://docs.google.com/file/d/{file_id}/edit
    def list_link_videos url
      file_id = get_file_id url
      spreadsheet_url = MAIL + file_id
      body = page_body spreadsheet_url
      body = decode_body body
      url_arr = split_body body
      find_link_mp4(url_arr).flatten
    rescue
      ""
    end

    private
    def get_file_id url
      url.split(DOC_GOOGLE)[1].remove("/view", "/preview", "/edit")
    end

    def page_body url
      agent = Mechanize.new
      page = agent.get url
      page.body
    end

    # We need to decode 2 times of body
    def decode_body body
      URI.unescape (URI.unescape body)
    end

    def split_body body
      result = []
      remove_fmt_stream = body.split(FMT_STREAM_MAP)[1]
      remove_fmt_list = remove_fmt_stream.split(FMT_LIST)[0]
      remove_fmt_list.split("|").each do |link|
        if link.include? "https"
          result << link
        end
      end
      result
    end

    # Our links that include mp4 and flv. But we only need to use mp4
    def find_link_mp4 links
      links.inject([]) do |result, link|
        if link.present?
          result << link.split(DRIVEID)[0]
        end
      end
    end

    def check_link_video link
      result = ""
      ITAGS.each do |itag|
        if link.include? itag[:itag]
          link = add_link_redirect_google link
          result = {file: link, type: "mp4", label: itag[:label]}
        end
      end
      result
    end

    def add_link_redirect_google url
      REDIRECT_URL + url.split(VIDEO_PLAYBACK)[1]
    end
  end
end

You test with your logic class above in rails console:

 url = "https://docs.google.com/file/d/0B6VYU2mjTdy0WVRjb1BJUU1hYXM/view"
 test = GoogleDrive.list_link_videos url
 => [{:file=>"https://redirector.googlevideo.com/videoplayback?id=19e3c7fd6fd45f15&itag=18&source=webdrive&requiressl=yes&ttl=transient&mm=30&mn=sn-i3b7kn7y&ms=nxu&mv=m&pl=24&mime=video/mp4&lmt=1480990883861520&mt=1486433662&ip=1.55.242.188&ipbits=24&expire=1486448107&sparams=ip,ipbits,expire,id,itag,source,requiressl,ttl,mm,mn,ms,mv,pl,mime,lmt&signature=85587FE51A03DB230F0C6AB405F13B740F6ACD2E.07DAFA05888E9B7E72166698A570440DD7F0048A&key=ck2&app=explorer", :type=>"mp4", :label=>"360"}, {:file=>"https://redirector.googlevideo.com/videoplayback?id=19e3c7fd6fd45f15&itag=22&source=webdrive&requiressl=yes&ttl=transient&mm=30&mn=sn-i3b7kn7y&ms=nxu&mv=m&pl=24&mime=video/mp4&lmt=1480991186991194&mt=1486433662&ip=1.55.242.188&ipbits=24&expire=1486448107&sparams=ip,ipbits,expire,id,itag,source,requiressl,ttl,mm,mn,ms,mv,pl,mime,lmt&signature=B03D9642C17081DD62C7044FF20FF820BD4AC034.9F3D2F3517C478C5A4C4C8BA2E0B25E9A2B89BB6&key=ck2&app=explorer", :type=>"mp4", :label=>"720"}, {:file=>"https://redirector.googlevideo.com/videoplayback?id=19e3c7fd6fd45f15&itag=59&source=webdrive&requiressl=yes&ttl=transient&mm=30&mn=sn-i3b7kn7y&ms=nxu&mv=m&pl=24&mime=video/mp4&lmt=1480991172772703&mt=1486433662&ip=1.55.242.188&ipbits=24&expire=1486448107&sparams=ip,ipbits,expire,id,itag,source,requiressl,ttl,mm,mn,ms,mv,pl,mime,lmt&signature=6A1F51D66474BDF6CDEE76F8E15A7821A811B935.19A71F08DE4DBCD7D4A4C1AA6E6C237E4F4DEC83&key=ck2&app=explorer", :type=>"mp4", :label=>"480"}] 

View For Input URl

Now let's start to create view to input url for our logic. Create a file app/views/movies/index.html.erb, open file that currently created and fill it as code below:

<div class="container">
  <div class="panel panel-info">
    <div class="panel-heading">
      <h1>API Video Google Drive</h1>
    </div>
    <div class="panel-body">
      <%= form_tag movies_path, method: :post do %>
        <div class="form-group">
          <%= url_field_tag "url", nil, class: "form-control", required: true,
            placeholder: "https://docs.google.com/file/d/xxxxxxxxxxxxxxxx/view" %>
        </div>
        <div class="form-group">
          <%= submit_tag "Get Video Links",  class: "btn btn-success" %>
        </div>
      <% end %>
    </div>
  </div>
  <%= @links.present? ? render("result") : Your url have a problem %>
</div>

And we create one more file app/views/movies/_result.html.erb to show about result with codes below.

<div class="panel panel-info">
  <div class="panel-body">
    <div class="result">
      <% @links.each do |link| %>
        <dl>
          <dt>File:</dt>
          <dd><%= link[:file] %></dd>
          <dt>Type:</dt>
          <dd><%= link[:type] %></dd>
          <dt>Label:</dt>
          <dd><%= link[:label] %></dd>
        </dl>
      <% end %>
    </div>
  </div>
</div>

Now we need to fill other code in our controller app/controllers/movies_controller.rb.

class MoviesController < ApplicationController
  def index
  end

  def create
    url = params[:url]
    @links = GoogleDrive.list_link_videos url
    render :index
  end
end

Now you can run our application:

Note: THAT URL JUST WORKS WITH SHARE ANYONE, IF YOU WANT TO WANT WORK WITH URL PUBLIC OR PRIVATE URL, PLEASE CONTACT TO ME
