A small script that takes the snapchat dump memories.json file and will download all the files from it concurrently

download_snapchat_memories.py

import concurrent.futures
import os
import re
import json
import mimetypes

# required libraries
import magic
import requests

print(f"base_dir is {base_dir}")
print(f"json_file is {json_file}")
print(f"output_dir is {output_dir}")

    try:
        pieces = file_info['Download Link'].split('?')

        setup = requests.post(pieces[0], data=pieces[1], headers = {'Content-Type': 'application/x-www-form-urlencoded'})

        if setup.status_code == 200:
            uid = re.findall(r"sid=(.*?)&", file_info['Download Link'])[0]

        # If you want to download every file one at a time
        # for file in data["Saved Media"]:
        #     download_file(file)

        with concurrent.futures.ThreadPoolExecutor(4) as executor:
            executor.map(download_file, data["Saved Media"])

You can get the memory_history.json by requesting all your Snapchat data here

You'll need to install these python libraries for this to work.

pip3 install requests
pip3 install python-magic
