python MangaseeDL.py MANGA_NAME [CHAPTER_START [CHAPTER_END]]

Examples:

If nothing other than MANGA_NAME is provided, the script tries to download all chapters.

python MangaseeDL.py "One Piece"
python MangaseeDL.py "one piece"
python MangaseeDL.py one-piece

Note that MANGA_NAME is case-insensitive, and spaces could be replaced with hyphens.

If only CHAPTER_START is provided, that chapter is downloaded. The following commands will all download chapter 10 of the manga One Piece:

python MangaseeDL.py "One Piece" 10
python MangaseeDL.py one-piece 10
python MangaseeDL.py One-Piece 10

If CHAPTER_START and CHAPTER_END are both provided, the script tries to download CHAPTER_START to CHAPTER_END. The following commands will all download chapters 10 through 20 of the manga Diamond is Unbreakable:

python MangaseeDL.py "Daomond is Unbreakable" 10 20
python MangaseeDL.py "diamond is unbreakable" 10 20
python MangaseeDL.py diamond-is-unbreakable 10 20

• You can find the manga name through searching on mangasee123.com and finding out the index name. For example, if you search for JoJo’s Bizarre Adventure - Part 4 - Diamond Is Unbreakable, you’ll end up here: https://mangasee123.com/manga/Diamond-Is-Unbreakable. So the name you should enter is Diamond-Is-Unbreakable (case-insensitive).

As of the time of writing this script, mangasee123 serves mangas in the following format:

https://mangasee123.com/read-online/MANGANAME-chapter-CHAPTERNO-page-PAGENO.html

For example, One Piece chapter 1 page 51 can be read on:

https://mangasee123.com/read-online/One-Piece-chapter-1-page-51.html

If we inspect this url’s source, there’s two important variables in the JS codes:

vm.CHAPTERS: An array holding the information for each chapter and the number of its pages.

Example:

vm.CHAPTERS = [
  {
    "Chapter":"100010",
    "Page":"57",
    ...
  },
  {
    "Chapter":"100020",
    "Page":"24",
    ...
  },
  ...;

Note how the chapter has a leading 1 and a tailing zero. We strip that off.

vm.CurPathName: A url in which the images for that chapter is hosted.

Example:

vm.CurPathName = "official-ongoing-2.gamindustri.us";

so images for pages of this chapter are hosted on scans-hot.leanbox.us!

By checking the url for each page image, we can see it’s in the following format:

https://HOST/manga/MANGANAME/CHAPTER-PAGE.png

With CHAPTER and PAGE being 4 3 characters long, respectively.

So the aforementioned One Piece is hosted on:

https://official-ongoing-2.gamindustri.us/manga/One-Piece/0574-021.png

That’s practically it. You can see how this script is able to download mangas.
