python - 使用 Selenium 和 Python 在 Chrome 中同时登录多个帐户

Question

我管理着我公司大约 150 个电子邮件帐户，并且我为 Selenium WebDriver 编写了一个 Python 脚本，它可以自动执行操作（删除垃圾邮件、清空垃圾箱……）一个又一个帐户，一天几次，而且它也是如此很慢，而且总是崩溃。我读到在 Amazon AWS 上使用 Docker 的 Selenium Grid 可以完成这项工作，而且 Selenium WebDriver 的“并行”选项似乎也可以。

我需要同时做的事情：

1）登录（所有帐户）

2）执行操作（删除垃圾邮件，清空垃圾箱，...）

3) 关闭 Chrome 实例

我目前必须使用 for 循环来创建 150 倍于我存储在列表中的相同指令，而这根本没有优化，它会使我的计算机崩溃......简而言之，我知道这不是要走的路我期待着让它同时并行运行。

这是我正在使用的代码的缩短版本：

from selenium import webdriver
from selenium.webdriver.common.by import By
from selenium.webdriver.support.ui import WebDriverWait
from selenium.webdriver.support import expected_conditions as EC
from selenium.common.exceptions import TimeoutException


## GET THE USERS' EMAILS
emails = []
pwds = []
with open("users.txt", "r") as users_file: # Open the text file containing emails and pwds
  for line in users_file:
      email_and_pwd = line.split() # Extract the line of the .txt file as a list
      emails.append(email_and_pwd[0]) # Add the email in the emails list
      pwds.append(email_and_pwd[1]) # Add the pwd in the pwds list
nbr_users = len(emails) # number of users


## CREATE LISTS OF INSTRUCTIONS THAT WILL BE EXECUTED LATER AS CODE
create_new_driver = []
go_to_email_box = []
fill_username_box = []
fill_password_box = []
# Here I have the same type of lines to create lists that will contain the instructions to click on the Login button, then delete spams, then empty the trash, etc...


## FILL THE LISTS WITH INSTRUCTIONS AS STRINGS
for i in range(nbr_users):
  create_new_driver_element = 'driver' + str(i) + ' = webdriver.Chrome(options = chrome_options)'
  create_new_driver.append(create_new_driver_element)

  # Here I have the same type of lines to create the rest of the instructions to fill the lists


## EXECUTE THE INSTRUCTIONS SAVED IN THE LISTS
for user in range(nbr_users):
  exec(create_new_driver[user])
  # Here I have the same type of lines to execute the code contained in the previously created lists

在浏览互联网几天后没有结果，任何形式的帮助表示赞赏。非常感谢 ！

我试图对@Jetro Cao 的回答发表评论，但评论太多了。我将根据他的工作做出回应。

为什么你的程序很慢？

正如@Jetro Cao提到的，您正在按顺序而不是并行运行所有内容。

另一个工具会让这更容易吗？

是的。如果可能，您应该使用电子邮件管理工具（例如：G Suite for gmail），而不是通过 python 脚本单独登录这些帐户。

将我的 150 个帐户凭据存储在文本文件中是否安全？

不，除非这些是没有任何敏感电子邮件的毫无意义的机器人帐户。

代码建议：

总体而言，您的代码有了一个良好的开端。几点具体意见：

1. 避免使用 exec
2. 使用@Jetro Cao推荐的线程
3. 您没有向我们提供大部分代码。使用 selenium 时，可以使用一些技巧来帮助加快速度。一个例子是直接加载登录页面，而不是加载主页然后“单击”登录。
