如何修复 Python Selenium 脚本中的“innerHTML”错误？

Question

我在使用 Selenium 库使用 Python 开发的 gmail 发送脚本中遇到错误，我需要帮助来修复此错误。错误详情如下：

Traceback (most recent call last):
  File "C:\Users\Administrator\Desktop\New folder\gmailsender.py", line 101, in <module>
    sb.driver.execute_script(f'document.querySelector(\'div[role="textbox"]\').innerHTML = `{body_content}`;')
  ...
selenium.common.exceptions.JavascriptException: Message: javascript error: Failed to set the 'innerHTML' property on 'Element': This document requires 'TrustedHTML' assignment.

我收到错误的代码行：

sb.driver.execute_script(f'document.querySelector(\'div[role="textbox"]\').innerHTML = 

{body_content}

;')

脚本工作原理：将template.html文件中的html代码粘贴到邮件发送部分。

我编写了一个从gmail发送邮件的脚本，之前运行得很顺利，但是由于gmail的新更新，我认为我的脚本不再工作。我该如何解决这个错误？错误的完整版本：

如果您正在创建 gmail 发送脚本，那么最好使用专门用于发送邮件的库。这里我使用

smtplib

（简单邮件传输协议）：

import smtplib

s = smtplib.SMTP('smtp.gmail.com', 587)
s.starttls()
s.login('[email protected]', 'mysecretpassword1234')
message = 'message'
s.sendmail('[email protected]', 'receiver email address', message)
s.quit()

当然，如果你想让电子邮件有更多的功能，有主题和正文，你可以试试这个：

import smtplib
from email.mime.text import MIMEText 
from email.mime.multipart import MIMEMultipart   

s = smtplib.SMTP('smtp.gmail.com', 587)
s.ehlo()
s.starttls()
s.login('[email protected]', 'mysecretpassword1234')
msg = MIMEMultipart()
body = 'your message body'
msg['Subject'] = 'your subject for the email'
msg.attach(MIMEText(body))
email = msg
s.sendmail('[email protected]', 'receiver email address', msg=email)
s.quit()
