尝试从python发送电子邮件

Question

我是python的新手，当尝试使用python发送邮件时，我的程序如下

import smtplib
from smtplib import SMTP

sender = 'raju.ab@gmail.com'
receivers = ['sudeer.p@eunoia.in']

message = """ this message sending from python
for testing purpose
"""

try:
smtpObj = smtplib.SMTP('smtp.gmail.com', 587)
smtpObj.ehlo()
smtpObj.starttls()
smtpObj.ehlo()
smtpObj.login(username,password)
smtpObj.sendmail(sender, receivers, message)
smtpObj.quit()
print "Successfully sent email"
except smtplib.SMTPException:

打印“错误：无法发送电子邮件”

当我执行它时显示错误：无法发送电子邮件，如何在python中发送电子邮件，请解释

Answer 1

如此处所述： 如何使用Python以提供者身份通过Gmail发送电子邮件？

此代码有效。 但是GMAIL会警告您是否要允许此脚本发送电子邮件。 登录您的帐户，然后访问以下URL： https : //www.google.com/settings/security/lesssecureapps

import smtplib
gmail_user = "yourmail@gmail.com"
gmail_pwd = "mypassword"
FROM = 'yourmail@gmail.com'
TO = ['receiber@email.com'] #must be a list
SUBJECT = "Testing sending using gmail"
TEXT = "Testing sending mail using gmail servers"
# Prepare actual message
message = """\From: %s\nTo: %s\nSubject: %s\n\n%s
""" % (FROM, ", ".join(TO), SUBJECT, TEXT)
try:
  #server = smtplib.SMTP(SERVER) 
  server = smtplib.SMTP("smtp.gmail.com", 587) #or port 465 doesn't seem to work!
  server.ehlo()
  server.starttls()
  server.login(gmail_user, gmail_pwd)
  server.sendmail(FROM, TO, message)
  #server.quit()
  server.close()
  print 'successfully sent the mail'
except:
  print "failed to send mail"

Answer 2

我在代码中做了什么：

1，添加了一个错误对象以获取错误信息

import smtplib
from smtplib import SMTP       

try:
    sender = 'xxx@gmail.com'
    receivers = ['xxx.com']

    message = """ this message sending from python
    for testing purpose
    """
    smtpObj = smtplib.SMTP(host='smtp.gmail.com', port=587)
    smtpObj.ehlo()
    smtpObj.starttls()
    smtpObj.ehlo()
    smtpObj.login('xxx','xxx')
    smtpObj.sendmail(sender, receivers, message)
    smtpObj.quit()
    print "Successfully sent email"
except smtplib.SMTPException,error:
    print str(error)
    print "Error: unable to send email"

如果您运行此代码，您会看到一条错误消息，指出Google不允许您通过代码登录

gmail发生的变化：

1.登录gmail

2.转到此链接https://www.google.com/settings/security/lesssecureapps

3.单击启用，然后重试代码

希望对您有所帮助:)

但是，如果您启用它，则会存在安全威胁
