UnicodeEncodeError：'ascii‘编解码器不能在5-6位置编码字符:序数不在范围内(128个)

Question

我尝试通过SMTP简单地使用python。然而，不管我尝试了什么，它仍然显示了UnicodeEncodeError

import smtplib
import sys
print(sys.getdefaultencoding())
host = "smtp.gmail.com"
port = 587
username = "ppapa@gmail.com"
password = "ppapapxasfsdfsdfsdfsd"

email_conn = smtplib.SMTP(host,port) #call smtp method 
email_conn.ehlo()

错误提示：

utf-8
Traceback (most recent call last):
  File "Useemail.py", line 10, in <module>
    email_conn.ehlo()
  File "C:\Users\Lance\Anaconda3\lib\smtplib.py", line 439, in ehlo
    self.putcmd(self.ehlo_msg, name or self.local_hostname)
  File "C:\Users\Lance\Anaconda3\lib\smtplib.py", line 366, in putcmd
    self.send(str)
  File "C:\Users\Lance\Anaconda3\lib\smtplib.py", line 351, in send
    s = s.encode(self.command_encoding)
UnicodeEncodeError: 'ascii' codec can't encode characters in position 5-6: ordinal not in range(128)

我今天也有类似的问题。

我发现的问题是因为我的from_addr有UTF-8字符。您可以尝试设置email_conn.command_encoding = 'utf-8'。
