Python 3 script to extract images from HTTP Archive (HAR) files

extract_har.py

import json
import base64
import os

# make sure the output directory exists before running!
folder = os.path.join(os.getcwd(), "imgs")

with open("scr.har", "r") as f:
    har = json.loads(f.read())

entries = har["log"]["entries"]

for entry in entries:
    mimetype = entry["response"]["content"]["mimeType"]
    filename = entry["request"]["url"].split("/")[-1]
    image64 = entry["response"]["content"]["text"]

    if mimetype == "image/webp":
        file = os.path.join(folder, "{}.webp".format(filename))
        print(file)
        with open(file, "wb") as f:
            f.write(base64.b64decode(image64))

Thank you guys. This code is so old I barely remember it =)
