HoyoDL 0.1.2

Download any game file at any version of Hoyo games

HoyoDL

Download any file at any version from Hoyo games, with additional utilities.

Setting up

First, create an instance of the class :

>>> import HoyoDL
>>> client = HoyoDL(game="hk4e", version="5.5")

You can also specify the game and version separately :

>>> client = HoyoDL()
>>> client.setGame("hk4e")
>>> client.setVersion("5.4")

The list of games is as follow :

Game	Game ID	Minimum supported version
Genshin Impact	hk4e	2.3
Honkai: Star Rail	hkrpg	1.5
Zenless Zone Zero	nap	1.1

Downloading a file

To download a file, call downloadFile() and specify its path, the game and version must be defined :

>>> dl = client.downloadFile("GenshinImpact.exe")
>>> dl = client.downloadFile("GenshinImpact_Data/app.info")

This functions returns a requests.Response object, you can then use it to save your file :

>>> file = "GenshinImpact.exe"
>>> dl = client.downloadFile(file)
>>>
>>> with open(file, "wb") as f:
>>>     f.write(dl.content)

Or if you want to have a progress along with it, save it in chunks :

>>> file = "GenshinImpact.exe"
>>> dl = client.downloadFile(file)
>>> 
>>> with open(file, "wb") as f:
>>> 	for chunk in dl.iter_content(chunk_size=8192): # use chunk size of your choice
>>> 		f.write(chunk)

The tool also provides a shortcut function to download a block file using downloadBlock(), this functions returns a requests.Response object too :

>>> client = HoyoDL(game="hkrpg", version="3.1")
>>> block = "000a8acede9ed8aea7a8c3281a2f7ebd" # file extension is automatically added upon request as it differs between games
>>> dl = client.downloadBlock(block) # will download 000a8acede9ed8aea7a8c3281a2f7ebd.block

⚠️ Genshin uses folders for blocks, so you must add the folder name in the block name to download correctly :

>>> client = HoyoDL(game="hk4e", version="5.5")
>>> block = "00/35323818"
>>> dl = client.downloadBlock(block) # will download 00/35323818.blk

If you don't want to have a requests.Response object but rather a URL directly, you can use getFileURL() instead :

>>> client = HoyoDL(game="hk4e", version="5.5")
>>> url = client.getFileURL("GenshinImpact.exe")
>>> print(url)
"https://autopatchhk.yuanshen.com/client_app/download/pc_zip/20250314110016_HcIQuDGRmsbByeAE/ScatteredFiles/GenshinImpact.exe"

Getting files names

If you don't know what files you can have, or want to get lists easily, you can call the following functions, each will return a list of files, each file being a dictionary in the following structure :

{
  "name": "path/to/file.ext",
  "md5": "md5 hash",
  "size": "size in bytes"
}

To get all blocks :

>>> files = client.getAllBlockFiles()
>>> dl = client.downloadFile(files[0]["name"])

To get all audio files :

>>> files = client.getAllAudioFiles()

To get all cutscenes files :

>>> files = client.getAllCutscenesFiles()

ℹ️ When running any of these functions for the first time, it may take a few additional seconds as the tool is fetching the files list, afterwards it will be cached for future calls until the game or version is changed.

Getting miscellaneous information

After selecting a game and version, you can get the date of when this version was released to the servers :

>>> client = HoyoDL(game="hk4e", version="2.7")
>>> date = client.getReleaseDate()
>>> print(date)
"April 29th, 2022 at 11:24:15"

You can also get the date as number directly if you don't want the formatted one, the output will be in the form YYYYmmddHHMMSS :

>>> date = client.getReleaseDate(raw=True)
>>> print(date)
20220429112415

You can also get the version hash if necessary :

>>> hash = client.getHash()
>>> print(hash)
"20220429112415_dDweiEHDnBI6cKmM"

Customizing the data

This tool works by using what is called a provider json file, this file contains all the games, versions and hashes for each version, the default file is hosted here, but you may want to also make your own to add custom games or add missing version. In theory this file is self updating everytime a game update but just in case this options is available.

To do so, create a json file in the same structure as the official one, host it wherever you want and pass the url to it when initializing the tool :

>>> client = HoyoDL(provider="https://example.com/path/file.json")
