Python:如何在请求中使用Chrome Cookie [英] Python: How to use Chrome cookies in requests

问题描述

我正在寻找一种方法，可以从chrome浏览器中获取Cookie(默认)，并通过请求使用它.

I am searching for a method to get my cookies from my chrome browser (default), and use it using requests.

我当然已经搜索了，例如发现了这个. 如何使用Python从网络浏览器中获取Cookie? 但这不再起作用，因为Chrome一直在更新.他们在答案中命名的模块上一次在2016年进行了测试.

I have ofcourse already searched around, and found for example this; How to get cookies from web-browser with Python? But that does not work anymore, because Chrome keeps on updating. And the modules they name in the answer were last tested in 2016.

所以，他们在答案中给出的代码是+我多余的东西，使饼干回来了

So, the code they gave at the answer was + my extra stuff to get the cookies back

import win32crypt
import browsercookie
import requests

session = requests.Session()
cj = browsercookie.chrome()
r = session.get("https://stackoverflow.com/", cookies=cj)
print session.cookies.get_dict()

但是当我运行它时(在我的浏览器中登录到stackoverflow时)，它返回{}.那不是很多(不是我想要的结果)

But when I run this (while being logged into stackoverflow on my browser), it return {}. And that's not alot (not the result I was loking for)

推荐答案

我有一个很好的脚本，可以直接在/Default/Cookies 上读取Chrome cookie.我想你会没事的.

I have a good script to read Chrome cookies directly on /Default/Cookies. I think you would work fine.

import sqlite3
import sys
from os import getenv, path
import os
from Crypto.Cipher import AES
from Crypto.Protocol.KDF import PBKDF2
import keyring

def get_cookies(url, cookiesfile):

    def chrome_decrypt(encrypted_value, key=None):
        dec = AES.new(key, AES.MODE_CBC, IV=iv).decrypt(encrypted_value[3:])
        decrypted = dec[:-dec[-1]].decode('utf8')
        return decrypted

    cookies = []
    if sys.platform == 'win32':
        import win32crypt
        conn = sqlite3.connect(cookiesfile)
        cursor = conn.cursor()
        cursor.execute(
            'SELECT name, value, encrypted_value FROM cookies WHERE host_key == "' + url + '"')
        for name, value, encrypted_value in cursor.fetchall():
            if value or (encrypted_value[:3] == b'v10'):
                cookies.append((name, value))
            else:
                decrypted_value = win32crypt.CryptUnprotectData(
                    encrypted_value, None, None, None, 0)[1].decode('utf-8') or 'ERROR'
                cookies.append((name, decrypted_value))

    elif sys.platform == 'linux':
        my_pass = 'peanuts'.encode('utf8')
        iterations = 1
        key = PBKDF2(my_pass, salt, length, iterations)
        conn = sqlite3.connect(cookiesfile)
        cursor = conn.cursor()
        cursor.execute(
            'SELECT name, value, encrypted_value FROM cookies WHERE host_key == "' + url + '"')
        for name, value, encrypted_value in cursor.fetchall():
            decrypted_tuple = (name, chrome_decrypt(encrypted_value, key=key))
            cookies.append(decrypted_tuple)
    else:
        print('This tool is only supported by linux and Mac')

    conn.close()
    return cookies


if __name__ == '__main__':
    pass
else:
    salt = b'saltysalt'
    iv = b' ' * 16
    length = 16

#get_cookies('YOUR URL FROM THE COOKIES', 'YOUR PATH TO THE "/Default/Cookies" DATA')
