我正在使用
smtplibMIMEText请帮助我解决这个问题。
这是我用来获取自定义 html 格式的代码：
import pandas as pd
import re
from bs4 import BeautifulSoup
class GenerateHTMLReport:
def __init__(self, debug_logger):
self.debug_logger = debug_logger
def get_styled_html(self, origin_df, source_df, course_df, state_df, city_df):
origin_html = origin_df.to_html(index=False)
source_html = source_df.to_html(index=False)
course_html = course_df.to_html(index=False)
state_html = state_df.to_html(index=False)
city_html = city_df.to_html(index=False)
soup_origin = BeautifulSoup(origin_html, 'html.parser')
soup_source = BeautifulSoup(source_html, 'html.parser')
soup_course = BeautifulSoup(course_html, 'html.parser')
soup_state = BeautifulSoup(state_html, 'html.parser')
soup_city = BeautifulSoup(city_html, 'html.parser')
for table in soup_origin.find_all('table') + soup_source.find_all('table') + soup_course.find_all('table') + soup_state.find_all('table') + soup_city.find_all('table'):
table['style'] = "border:1px solid black;border-collapse:collapse"
for th in soup_origin.find_all('th') + soup_source.find_all('th') + soup_course.find_all('th') + soup_state.find_all('th') + soup_city.find_all('th'):
th['style'] = "border:1px solid black;border-collapse:collapse;padding:2px;background-color:yellow;text-align:center"
th['bgcolor'] = "yellow"
th['align'] = "center"
for table in soup_origin.find_all('table') + soup_source.find_all('table') + soup_course.find_all('table') + soup_state.find_all('table') + soup_city.find_all('table'):
rows = table.find_all('tr')
for row in rows:
cells = row.find_all('td')
if any(cell.text.strip() == 'Grand Total' for cell in cells):
for cell in cells:
cell['style'] = "border:1px solid black;border-collapse:collapse;padding:2px;background-color:#d7e4fb;text-align:center"
cell['bgcolor'] = "#d7e4fb"
cell['align'] = "center"
else:
for cell in cells:
cell['style'] = "border:1px solid black;border-collapse:collapse;padding:2px;background-color:white;text-align:center"
cell['bgcolor'] = "white"
cell['align'] = "center"
leave_line = """<div><br></div>"""
full_html = str(soup_origin) + leave_line + str(soup_source) + leave_line + str(soup_course) + leave_line + str(soup_state) + leave_line + str(soup_city)
return full_html
这是我用来发送电子邮件的：

except Exception as e:

在GenerateHTMLReport类中添加save_html_report方法：
def save_html_report（自身，origin_df，source_df，course_df，state_df，city_df，文件名）： html_content = self.get_styled_html(origin_df, source_df, course_df, state_df, city_df) 打开（文件名，'w'，编码='utf-8'）作为文件： 文件.write(html_content)
修改Emailer类中的emailer方法： 使用以下代码替换现有的电子邮件程序方法：
def emailer(self, sender_email,receiver_email,authentication_file):
with open(athentication_file, 'r') as file:
content = file.read()
creds = yaml.load(content, yaml.FullLoader)
user = creds['user']
password = creds['password']
smtp_server = 'smtp.gmail.com'
smtp_port = 587
smtp_username = user
smtp_password = password
# Create a multipart message object
msg = MIMEMultipart()
# Set email headers
msg['From'] = sender_email
msg['To'] = receiver_email
msg['Subject'] = self.subject
receiver_emails_li = [email.strip() for email in receiver_email.split(',')]
msg.attach(MIMEText(self.body, 'plain'))
# Generate and save the HTML report
html_report_file = 'report.html'
self.html_rep.save_html_report(self.originwise_report, self.sourcewise_report, self.coursewise_report, self.statewise_report, self.citywise_report, html_report_file)
# Attach the HTML file
with open(html_report_file, 'rb') as file:
attachment = MIMEApplication(file.read(), _subtype="html")
attachment.add_header('Content-Disposition', 'attachment', filename=html_report_file)
msg.attach(attachment)
try:
# Connect to the SMTP server
server = smtplib.SMTP(smtp_server, smtp_port)
server.starttls()
# Log in to your email account
server.login(smtp_username, smtp_password)
# Send the email
server.sendmail(sender_email, receiver_emails_li, msg.as_string())
# Close the SMTP server connection
server.quit()
print('Email sent successfully.')
except Exception as e:
print('Email Error: ', str(e))
您可以通过将报告作为附件发送来避免 gmail 对电子邮件正文内容的大小限制，收件人可以下载并查看完整的报告，而不会遇到剪切问题
