Django发送html邮件的方法
本文实例讲述了Django发送html邮件的方法。分享给大家供大家参考。具体如下：
在Django中，发送邮件非常的方便，一直没有时间，今天来做一个小小的总结吧。
我们常用的当然是通过send_mail发送邮件：
subject,message,from_email 和recipient_list 这四个参数是必须的。
subject: 字符串，表示邮件标题。
message: 字符串，表示邮件内容。
from_email: 字符串，表示发件邮箱。
recipient_list: 字符串列表，列表中每个成员都是一个邮箱地址，而且每个收件人都会在 “收件人/To:” 栏看到出现在recipient_list 中的其他收件人。
fail_silently: （可选）布尔值。为False 时，send_mail 会抛出smtplib.SMTPException 异常。smtplib 文档列出了所有可能的异常。这些异常都是SMTPException 的子类。
auth_user: （可选）SMTP服务器的认证用户名。没提供该参数的情况下，Django会使用EMAIL_HOST_USER 配置项的设置。
auth_password: （可选）SMTP服务器的认证密码，没提供该参数的情况下，Django会使用EMAIL_HOST_PASSWORD 配置项的设置。
connection: （可选）发送邮件的后端。没提供该参数的情况下，Django会使用默认后端的实例。
以下是一个简单的事例：
from django.core.mail import send_mail
from django.template import Context, loader
context = {
'nickname': user.nickname,
'verify_url': verify_url,
}
email_template_name = 'template.html'
t = loader.get_template(email_template_name)
mail_list = [user.email, ]
send_mail(
subject=title,
message=t.render(Context(context)),
from_email=EMAIL_HOST_USER,# 发件邮箱
recipient_list=mail_list,
fail_silently=False,
auth_user=EMAIL_HOST_USER, # SMTP服务器的认证用户名
auth_password=EMAIL_HOST_PASSWORD, # SMTP服务器的认证用户密码
connection=None
)
用过的人可能会发现，你在template.html中的标签，并没有通过浏览器的解析而显示出来了。
怎么办？我们要发送HTML邮件，Django当然是为你提供了好的解决方案的，请看下面一段代码：
from django.core.mail import EmailMultiAlternatives from django.template import Context, loader subject, from_email, to = title, EMAIL_HOST_USER, mail_list html_content = t.render(Context(context)) msg = EmailMultiAlternatives(subject, html_content, from_email, to) msg.attach_alternative(html_content, "text/html") msg.send()
看，很简单吧，那么现在我要稍稍的做一点点改动，我需要发送附件给收件人，只需要做一个简单的修改即可：
from django.core.mail import EmailMultiAlternatives from django.template import Context, loader subject, from_email, to = title, EMAIL_HOST_USER, mail_list html_content = t.render(Context(context)) msg = EmailMultiAlternatives(subject, html_content, from_email, to) msg.attach_alternative(html_content, "text/html") msg.attach_file(u'D:/My Documents/Python/doc/test.doc') # 添加附件发送 msg.send()
好了，到此为止，发送邮件已经结束了。不过，此时，需求变了，我在自己的网站上配置了多个发送邮件的用户名和密码，现在需要用我指定的用户名和密码给用户发送邮件，该怎么办呢？请看下面的一段代码：
from django.core.mail import EmailMultiAlternatives，get_connection from django.template import Context, loader conn = get_connection() # 返回当前使用的邮件后端的实例 conn.username = 'my_email@qq.com'# 更改用户名 conn.password = 'my_email' # 更改密码 conn.host = 'smtp.exmail.qq.com' # 设置邮件服务器 conn.open() # 打开连接 EMAIL_HOST_USER = 'my_email@qq.com' subject, from_email, to = title, EMAIL_HOST_USER, mail_list html_content = t.render(Context(context)) msg = EmailMultiAlternatives(subject, html_content, from_email, to) msg.attach_alternative(html_content, "text/html") conn.send_messages([msg,]) # 我们用send_messages发送邮件 conn.close()# 发送完毕记得关闭连接
看来，也不是很难吧！
django.core.mail 的 get_connection()方法返回你当前使用的邮件后端的实例。
默认情况下，对 get_connection() 的调用会返回一个邮件后端实例，具体是哪个后端由EMAIL_BACKEND 配置项决定。如果指定了``backend`` 参数，就会对该后端进行实例化。
友情提示:在发送的HTML邮件中包含图片时,应该制定可以通过http访问的地址。如:http://www.baidu.com/medias/xxx.png
希望本文所述对大家的Python程序设计有所帮助。
