ChromeSessionParser 语法问题

Question

我的部分代码遇到问题，我在底部添加了错误。问题是围绕 sqllite3.operationError 部分出现的。我试图删除它，但是当我对第 68 行“def getpath（）：”执行另一个错误时，我不明白为什么会出现错误，并且一如既往地感谢所有帮助。我的代码通常用于将登录数据从我的数据库中取出并显示在 csv 文件中

import os
import sys
import sqlite3
try:
    import win32crypt
except:
    pass
import argparse



def args_parser():
    parser = argparse.ArgumentParser(description="Retrieve Google Chrome Passwords")
    parser.add_argument("--output", help="Output to csv file", action="store_true")
    args = parser.parse_args()
    if args.output:
        csv(main())
    else:
            for data in main():
                print (data)



def main():
    info_list = []
    path = getpath()
    try:
        connection = sqlite3.connect(path + "Login Data")
        with connection:
            cursor = connection.cursor()
            v = cursor.execute('SELECT action_url, username_value, password_value FROM logins')
            value = v.fetchall


        for information in value:
            if os.name == 'nt':
                password = win32crypt.CryptUnprotectData(information[2], None, None, None, 0)[1]
                if password:
                    info_list.append({
                        'origin_url': information[0],
                        'username': information[1],
                        'password': str(password)
                    })



    except sqlite3.OperationalError as e:
        e = str(e)
        if (e == 'database is locked'):
            print('[!] Make sure Google Chrome is not running in the background')

        elif (e == 'no such table: logins'):
            print('[!] Something wrong with the database name')
            sys.exit(0)
        elif (e == 'unable to open database file'):

        else:
            print (e)
            sys.exit(0)



    return info_list



def getpath():
        if os.name == "nt":
            # This is the Windows Path
            PathName = os.getenv('localappdata') + '\\Google\\Chrome\\User Data\\Default\\'
            if (os.path.isdir(PathName) == False):
                print('[!] Chrome Doesn\'t exists')
                sys.exit(0)

            return PathName



def csv (info):

            csv_file.write(('%s, %s, %s \n' % (data['origin_url'], data['username'], data['password'])).encode('utf-8'))
    print ("Data written to Chromepass.csv")




if __name__ == '__main__':
    args_parser()

错误

正确的方法是：

except sqlite3.OperationalError as e:

而你main() 应该是这样的：

def main():
    info_list = []
    path = getpath()
    try:
        connection = sqlite3.connect(path + "Login Data")
        with connection:
            cursor = connection.cursor()
            v = cursor.execute('SELECT action_url, username_value, password_value FROM logins')
            value = v.fetchall


        for information in value:
            if os.name == 'nt':
                password = win32crypt.CryptUnprotectData(information[2], None, None, None, 0)[1]
                if password:
                    info_list.append({
                        'origin_url': information[0],
                        'username': information[1],
                        'password': str(password)
                    })



    except sqlite3.OperationalError as e:
        e = str(e)
        if (e == 'database is locked'):
            print '[!] Make sure Google Chrome is not running in the background'
            sys.exit(0)
        elif (e == 'no such table: logins'):
            print '[!] Something wrong with the database name'
            sys.exit(0)
        elif (e == 'unable to open database file'):
            print '[!] Something wrong with the database path'
            sys.exit(0)
        else:
            print e
            sys.exit(0)



    return info_list
