篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了在python中发送电子邮件（MIMEmultipart）相关的知识，希望对你有一定的参考价值。
我应该如何在同一个机构中发送包含文本格式和html格式的电子邮件？ MIMEmultipart有什么用？
MIMEMultipart([MIMEText(msg, 'text'),MIMEtext(html,'html')])
我能够收到一封电子邮件，但身体空白
PS：我正在尝试发送文本并在同一个正文中附上一张桌子。我不想把表作为附件发送。
html = """
<html>
<head>
<style>
table, th, td {{ border: 1px solid black; border-collapse: collapse; }} th, td {{ padding: 5px; }}
</style>
</head>
<body><p>Hello, Friend This data is from a data frame.</p>
<p>Here is your data:</p>
{table}
<p>Regards,</p>
<p>Me</p>
</body>
</html> """
text = """
Hello, Friend.
Here is your data:
{table}
Regards,
Me"""
text = text.format(table=tabulate(df, headers=list(df.columns), tablefmt="grid"))
html = html.format(table=tabulate(df, headers=list(df.columns), tablefmt="html"))
if(df['date'][0].year==1900 and df['date'][0].month==datetime.date.today().month and df['date'][0].day==datetime.date.today().day):
a2=smtplib.SMTP(host='smtp-mail.outlook.com', port=587)
a2.starttls()
myadd='abc@gmail.com'
passwd=getpass.getpass(prompt='Password: ')
try :
a2.login(myadd,passwd)
except Exception :
print("login unsuccessful")
def get_contacts(filename):
name=[]
email=[]
with open('email.txt','r') as fl:
l=fl.readlines()
print(l)
print(type(l))
for i in l:
try:
name.append(i.split('
')[0].split()[0])
email.append(i.split('
')[0].split()[1])
except Exception:
break
fl.close()
return (name,email)
def temp_message(filename):
with open(filename,'r') as fl1:
l2=fl1.read()
return(Template(l2))
name,email=get_contacts('email.txt')
tmp1=temp_message('temp1.txt')
for name,eml in zip(name,email):
msg=MIMEMultipart([MIMEText(msg, 'text'),MIMEtext(html,'html')])
message=tmp1.substitute(USER_NAME=name.title())
print(message)
msg['FROM']=myadd
msg['TO']=eml
msg['Subject']="This is TEST"
msg.attach(MIMEText(message, 'plain'))
# msg.set_payload([MIMEText(message, 'plain'),MIMEText(html, 'html')])
# send the message via the server set up earlier.
a2.send_message(msg)
del msg
a2.quit()
答案
您需要将消息创建为
MIMEMultiPart('alternative')
然后附上两个MIMEText部分。
>>> text = 'Hello World'
>>> html = '<p>Hello World</p>'
>>> msg = MIMEMultipart('alternative')
>>> msg['Subject'] = 'Hello'
>>> msg['To'] = 'a@example.com'
>>> msg['From'] = 'b@example.com'
>>> msg.attach(MIMEText(text, 'plain'))
>>> msg.attach(MIMEText(html, 'html'))
>>> s.sendmail('a@example.com', 'b@example.com', msg.as_string())
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
NameError: name 's' is not defined
>>> s = smtplib.SMTP('localhost:1025')
>>> s.sendmail('a@example.com', 'b@example.com', msg.as_string())

重新设计的电子邮件包（Python 3.6+）可用于发送相同的消息，如下所示：
>>> from email.message import EmailMessage
>>> msg = EmailMessage()
>>> msg['Subject'] = 'Hello'
>>> msg['To'] = 'a@example.com'
>>> msg['From'] = 'b@example.com'
>>> msg.set_content(text)
>>> msg.add_alternative(html, subtype='html')
>>> s.send_message(msg)
输出：
---------- MESSAGE FOLLOWS ----------
Subject: Hello
To: a@example.com
From: b@example.com
MIME-Version: 1.0
Content-Type: multipart/alternative;
boundary="===============1374158239299927384=="

另一答案
在'与'：
def temp_message(filename):
with open(filename,'r') as fl1:
l2=fl1.read()
将其更改为：
def temp_message(filename):
filename = temp_message('temp1.txt') #changed tmp1 to filename
with open(filename, 'w+', encoding='utf-8') as fl1:
fl1.write(text)
fl1.write(html)
fl1.write(regards)
您可以拆分文本变量的“问候”部分，以便您的html（表格）可以在两者之间。我很困惑你的问题是什么（很多编辑）但是如果我没弄错你的fl1（tempt1.txt）没有任何数据你只是'读'（r）文本文件但是没有什么都写不出来。我还建议您将'tmp1 = temp_message（'temp1.txt'）'放在'def temp_message（filename）'中以避免混淆。

有没有办法在没有 Windows 询问“你想如何打开这个文件”的情况下在 python 中发送电子邮件？
