创建smtp()时出现Python smtplib错误：'utf-8‘编解码器无法解码字节

我不能用gmail.com和mail.ru(bk.ru)以任何方式解决发送电子邮件的问题:当创建SMTP时，即使是空的，也会出现这个错误。我使用PyCharm 2020.1
import requests
import smtplib # Импортируем библиотеку по работе с SMTP
from email.mime.multipart import MIMEMultipart # Многокомпонентный объект
from email.mime.text import MIMEText # Текст/HTML
from email.mime.image import MIMEImage # Изображения
addr_from = "zabrell@bk.ru" # Адресат
addr_to = "zabrell@bk.ru" # Получатель
password = "***" # Пароль
msg = MIMEMultipart() # Создаем сообщение
msg['From'] = addr_from # Адресат
msg['To'] = addr_to # Получатель
msg['Subject'] = '1' # Тема сообщения
body = '1'
msg.attach(MIMEText(body, 'plain')) # Добавляем в сообщение текст
server = smtplib.SMTP_SSL('smtp.mail.ru', 465) # Создаем объект SMTP
server.login(addr_from, password) # Получаем доступ
server.send_message(msg) # Отправляем сообщение
server.quit() # Выходим如果我替换掉
server = smtplib.SMTP_SSL('smtp.mail.ru', 465)使用
server = smtplib.SMTP_SSL()
server.connect('smtp.mail.ru', 465)即使没有_SSL(但它没有连接到服务器)，在smtplib.SMTP_SSL()阶段仍然会出现这个错误
Traceback (most recent call last):

hostname, aliases, ipaddrs = gethostbyaddr(name)
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xf7 in position 10: invalid start byte
Process finished with exit code 1我理解这个错误的含义，但看起来它就在smtplib本身的某个地方--这让我很困惑

该库尝试使用socket.getfqdn()找出要发送到远程服务器的本地主机名：
...
if local_hostname is not None:
self.local_hostname = local_hostname
else:
# RFC 2821 says we should use the fqdn in the EHLO/HELO verb, and
# if that can't be calculated, that we should use a domain literal
# instead (essentially an encoded IP address like [A.B.C.D]).
fqdn = socket.getfqdn()
if '.' in fqdn:
self.local_hostname = fqdn
...所以问题是:你的主机名是什么？问题可能是它包含非ascii字符，并且无法解码为UTF-8。
除了更改主机名之外，一种可能的解决方案是在构造函数中显式传递local_hostname：
server = smtplib.SMTP_SSL('smtp.mail.ru', 465, 'your.host.name')页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
