ValueError at /success在django EmailMultiAlternatives中无效的地址.&

Question

我想发送到多个电子邮件，但我得到了这个raise ValueError('无效地址"%s"' % addr)值:无效地址"['[e-mail]'， '[e-mail]'， '[e-mail]']">

email_id = ["[e-mail]","[e-mail]","[e-mail]"]
username = name
email = email_id
######################### mail system ####################################
htmly = get_template('email/Email.html')
d = { 
's_id' : s_id,
'username': username, 
'tran_id' : tran_id,
'amount'  : amount
}
subject, from_email, to = 'welcome', '[e-mail]', email
html_content = htmly.render(d)
msg = EmailMultiAlternatives(subject, html_content, from_email, [to])
msg.attach_alternative(html_content, "text/html")
msg.send()

Answer 1

您将数组类型发送给另一个数组，因此更改了数组尺寸。请这样核对。

email_id = ["[e-mail]","[e-mail]","[e-mail]"]
username = name
email = email_id
######################### mail system ####################################
htmly = get_template('email/Email.html')
d = { 
's_id' : s_id,
'username': username, 
'tran_id' : tran_id,
'amount'  : amount
}
subject, from_email, to = 'welcome', '[e-mail]', email
html_content = htmly.render(d)
msg = EmailMultiAlternatives(subject, html_content, from_email, to)
msg.attach_alternative(html_content, "text/html")
msg.send()

Answer 2

正如其他人指出的那样，您不应该将to括在方括号中，因为它已经是一个字符串列表，这正是参数所期望的。请看下面的例子:

msg = EmailMultiAlternatives("subject", html_content, "from@@gmail.com", ["to@@gmail.com", "to2@@gmail.com", "to3@@gmail.com"])
