Program Requirements:After registering on the user registration page, the system will send an email to the user's email address, and the user will click on the link to activate the account, where the user information in the link needs to be encrypted.
One of the activation of their mailbox smtp service operation will not be explained, on a very clear explanation, you can also go online to search for detailed steps
First of all, configure the configuration related to sending emails in the settings file of the Django project as follows:
# Fixed writing EMAIL_BACKEND = '' # smtp server address EMAIL_HOST = '' # Fixed port number EMAIL_PORT = 25 # Mailboxes for sending emails EMAIL_HOST_USER = '2746565701@' # Client authorization password set in mailbox EMAIL_HOST_PASSWORD = 'ytnvwapcbxmcdfig' # The sender as seen by the recipient, in pointed brackets must match the user above EMAIL_FROM = 'Daily Fresh<2746565701@>'
The user module's file about itsdangerous and mail sending code is as follows, the rest of the project's operation code is deleted here, and a class-based view is used here:
Basic logic:
- Encrypt the user information in the link using itsdangerous module to generate an encrypted user information token;
- Call the methods related to Django Send Mail to send emails (the configuration of emails is already configured);
- The link sent in the email has a variable parameter that contains the user id encrypted;
- After receiving the email, the user clicks on the link and jumps to the corresponding view class for processing;
- The view class responsible for activation, decrypting the user's information, obtaining the user id, and querying to the corresponding user (the process determines whether the encrypted information has timed out);
- Change the value of the is_active field in the Users table in the database for the corresponding user to 1 to indicate that this user is active;
- Jump to the home page;
