这就是我正在尝试做的事情。 我想从 Chrome 的 sqlite 文件中读取 cookie，在 python 上使用它们，然后再次将它们保存到 Chrome 的 sqlite 文件中，因为它们在与 python 一起使用时可能已被更新。
这或多或少是我必须测试的代码，我可以提取它们并正确使用它们，但我无法设法在 sqlite 上更新它们并继续在浏览器上使用它们。
我什至不确定我是否使用了正确的类型，或者是否将正确的类型传递给 UPDATE，在将 newEncrypted 传递给 sqlite 之前我是否应该对其执行任何操作？
- 加密值的 type() 是缓冲区
- 解密后的type()是unicode
newEncrypted 的 type() 是 str
import shutil, cookielib, sqlite3, win32crypt def decrypt(result): cookies = [] for host_key,name,value,expires_utc,encrypted_value in result: #print "Adding cookie" if value == '': print encrypted_value decrypted = win32crypt.CryptUnprotectData(encrypted_value, None, None, None, 0)[1].decode('utf-8') else: decrypted = value cookies.append(cookielib.Cookie(None, name, decrypted, '80', True, host_key, True, False, '/', True, False, (int(expires_utc)/1000000)-11644473600, False, None, None, None, False)) return cookies cookie_file = "C:/Users/Daviid/AppData/Local/Google/Chrome/User Data/Default/Cookies" conn = sqlite3.connect(cookie_file) cursor = conn.cursor() sql = 'select host_key,name,value,expires_utc,encrypted_value from cookies where host_key = ".google.com" or host_key = "www.google.com"' cursor.execute(sql) result = cursor.fetchall()[0] cookies = decrypt(result) ### # Use Cookies in urllib, Requests, whatever... # cookies get updated ### updatedCookie = cookies[0] updatedCookie.value = "NewValue" newEncrypted = win32crypt.CryptProtectData(updatedCookie.value, '', None, None, None, 0) cursor.execute("UPDATE cookies SET encrypted_value=? WHERE host_key = ? AND name = ?",(newEncrypted, updatedCookie.domain, updatedCookie.name)) cursor.close() conn.commit() conn.close()

sqlite 文档页面:[Python]: sqlite3 - DB-API 2.0 interface for SQLite databases .
code.py:
import sys

else:

cookies.append((host_key, name, expires_utc, decrypted, decrypted_descr, value))
# Idx: 0 1 2 3 4 5

for idx, cookie_tuple in enumerate(cookies):

updated_cookie = cookies[cookie_idx]
print_cookie(cookie_idx, updated_cookie, print_data=True)

注释:
- 我将代码拆分为函数，使其更加模块化(可重用和参数化)
- 我没有安装cookielib，所以我删除了引用它的所有部分，并使用元组来存储cookie数据(我知道
dict或collections.namedtuple会更好，但我不想添加更多代码，因为这部分无论如何都不会保留) - 没有错误处理
- 某些功能仅用于打印目的
- 作为测试，我选择了其中一个 Cookie，并且仅保留其(加密)数据的前一半。当然它会失效，但这只是为了演示目的
- key 是
buffer(encrypted)(在update_cookie中)，因为cookies.encrypted_value列是一个BLOB - 它仅兼容Python2(注意到问题中的
#print "Adding cookie")，因为在Python3中> 字符串是 unicode(并且buffer不存在)
