Ich habe versucht, SMTP in Python zu verwenden gmail zu senden, aber es scheiterte

Question

hier ist mein Skript:

from email.mime.text import MIMEText 
import smtplib 
msg=MIMEText('hi, send by python.....','plain','utf-8') 
from_addr='user@gmail.com' 
passowrd='psw' 
to_addr='user@gmail.com' 
s=smtplib.SMTP('smtp.gmail.com',587) 
s.login(from_addr,password) 
s.sendmail(from_addr, [to_addr], msg.as_string()) 

, wenn es ausgeführt wird, Fehler auftritt:

Traceback (most recent call last): 
File "C:\Users\bicuilin\Desktop\begin.py", line 17, in <module> 
s.login(from_addr, password) 
File "C:\Users\bicuilin\AppData\Local\Programs\Python\Python35\lib\smtplib.py", line 696, in login 
"SMTP AUTH extension not supported by server.") 
smtplib.SMTPNotSupportedError: SMTP AUTH extension not supported by server. 

Ich versuche, es zu beheben. Ich füge folgenden Code:

... 
s.ehlo() 
s.starttls() 
s.login(from_addr, password) 
s.sendmail(from_addr, [to_addr], msg.as_string()) 
s.quit() 

hier kommt Fehler, den ich wirklich nicht verstehen:

Traceback (most recent call last): 
File "C:\Users\bicuilin\Desktop\begin.py", line 20, in <module> 
s.login(from_addr, password)

Answer 1

Sie haben SMTP_SSL Klasse verwenden und es funktioniert (getestet hier). keine Notwendigkeit, starttls (wird sowieso nicht funktionieren)

from email.mime.text import MIMEText 
import smtplib 
msg=MIMEText('hi, send by python.....','plain','utf-8') 
from_addr='user@gmail.com' 
password='psw' 
to_addr='user@gmail.com' 
s=smtplib.SMTP_SSL('smtp.gmail.com') 
s.login(from_addr,password) 
s.sendmail(from_addr, [to_addr], msg.as_string())
