python-3.x - 统一码编码错误 : 'ascii' codec can't encode characters in position 5-6: ordinal not in range(128)

Question

我尝试通过 SMTP 简单地使用 python 调用 gmail。 然而，无论我怎样尝试，它仍然显示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)

Answer 1

我今天遇到了类似的问题。

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' 。
