通过 python 发送带有 excel xlsx 附件的电子邮件 (gmail) 时出错

Question

我正在尝试通过 python 以 gmail 作为主机发送电子邮件，如下所示：

# Import smtplib for the actual sending function
import smtplib

# For guessing MIME type
import mimetypes

# Import the email modules we'll need
import email
import email.mime.application

# Create a text/plain message
msg = email.mime.Multipart.MIMEMultipart()
msg['Subject'] = 'Greetings'
msg['From'] = 'x@gmail.com'
msg['To'] = 'x@gmail.com'

# The main body is just another attachment
body = email.mime.Text.MIMEText("""Hello, how are you? I am fine.
This is a rather nice letter, don't you think?""")
msg.attach(body)

# PDF attachment
filename=r'C:\Users\cost9\OneDrive\Documents\PYTHON\TEST0530\testingemail.xlsx'
fp=open(filename,'rb')
att = email.mime.application.MIMEApplication(fp.read(),_subtype="xlsx")
fp.close()
att.add_header('Content-Disposition','attachment',filename=filename)
msg.attach(att)

# send via Gmail server
# NOTE: my ISP, Centurylink, seems to be automatically rewriting
# port 25 packets to be port 587 and it is trashing port 587 packets.
# So, I use the default port 25, but I authenticate. 
s = smtplib.SMTP("smtp.gmail.com")
s.starttls()
s.login('x@gmail.com','password')
s.sendmail('x@gmail.com',['x@gmail.com'], msg.as_string())
s.quit()

不幸的是，我在计算了大约 20 秒后得到了错误：

error: [Errno 10060] A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond

我认为我已经关闭了 gmail 的安全设置，这样它就会通过，但这也不起作用。我正在尝试将带有电子邮件的 excel (xlsx) 附件发送给自己。不知道怎么了。

编辑：以下建议后的新错误：

Answer 1

改后试试

s = smtplib.SMTP("smtp.gmail.com")

至

s = smtplib.SMTP("smtp.gmail.com", 587)

Answer 2

我修复了更正 MIME 类型的相同问题：

'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'

通过 python 发送带有 excel xlsx 附件的电子邮件 (gmail) 时出错
