How does Django send html mails: djangohtml mails

This article describes how Django sends html emails. Share it with you for your reference. The details are as follows:

In Django, sending emails is very convenient and there is no time. Let's make a summary today.

We usually use send_mail to send Emails:
Copy codeThe Code is as follows: send_mail (subject, message, from_email, recipient_list, fail_silently = False, auth_user = None, auth_password = None, connection = None)

The subject, message, from_email, and recipient_list parameters are required.

Subject: String, indicating the mail title.
Message: String, indicating the mail content.
From_email: String, indicating the sender's mailbox.
Recipient_list: String list. Each member in the list is an email address, and each recipient will see other recipients in the "recipient/To:" column in the recipient_list.
Fail_silently: (optional) Boolean value. If the value is False, send_mail throws an smtplib. SMTPException. The smtplib document lists all possible exceptions. These exceptions are subclasses of SMTPException.
Auth_user: (optional) authentication username of the SMTP server. If this parameter is not provided, Django uses the EMAIL_HOST_USER configuration item settings.
Auth_password: (optional) authentication password of the SMTP server. If this parameter is not provided, Django uses the EMAIL_HOST_PASSWORD configuration item.
Connection: (optional) the backend of the email. If this parameter is not provided, Django uses the default backend instance.

The following is a simple example:

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), from_email = EMAIL_HOST_USER, # sender email recipient_list = mail_list, sender = False, auth_user = EMAIL_HOST_USER, # SMTP Server Authentication username auth_password = EMAIL_HOST_PASSWORD, # SMTP server authentication user password connection = None)

Users can find that the tags in template.html are not displayed through browser parsing.

What should I do? We want to send an HTML email. Django certainly provides a good solution for you. Please refer to the following code:

from django.core.mail import EmailMultiAlternativesfrom django.template import Context, loadersubject, from_email, to = title, EMAIL_HOST_USER, mail_listhtml_content = t.render(Context(context))msg = EmailMultiAlternatives(subject, html_content, from_email, to)msg.attach_alternative(html_content, "text/html")msg.send()

Look, it's easy. Now I want to make a little change. I need to send the attachment to the recipient, just make a simple modification:

From django. core. mail import EmailMultiAlternativesfrom django. template import Context, loadersubject, from_email, to = title, EMAIL_HOST_USER, mail_listhtml_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 ') # Add an attachment to send msg. send ()

Now, the email has been sent. However, at this time, the demand has changed. I have configured multiple email sending usernames and passwords on my website. Now I need to use the user name and password I specified to send emails to users, what should I do? See the following code:

From django. core. mail import EmailMultiAlternatives, get_connectionfrom django. template import Context, loaderconn = get_connection () # Return the currently used mail backend instance conn. username = 'my _ email@qq.com '# change the user name conn. password = 'my _ email '# Change password conn. host = 'smtp .exmail.qq.com '# Set the mail server conn. open () # open the connection EMAIL_HOST_USER = 'my _ email@qq.com 'subject, from_email, to = title, EMAIL_HOST_USER, mail_listhtml_content = t. render (Context (context) msg = EmailMultiAlternatives (subject, html_content, from_email, to) msg. attach_alternative (html_content, "text/html") conn. send_messages ([msg,]) # Use send_messages to send the email conn. close () # close the connection after sending the message

It seems that it is not very difficult!

The get_connection () method of django. core. mail returns the backend instance of the email you are currently using.
Copy codeThe Code is as follows: get_connection (backend = None, fail_silently = False, * args, ** kwargs)
By default, the call to get_connection () will return a mail backend instance. The specific backend is determined by the EMAIL_BACKEND configuration item. If the ''backend'' parameter is specified, the backend is instantiated.

Tip: When an HTML email contains an image, you must specify an address that can be accessed through http. Such as: http://www.baidu.com/medias/xxx.png
