I am writing a little web application based on Miguel Grinberg's Flasky. I use the exact same code for user send reset password mail using gmail.
The following as my email.py file here i can implement mail sending function
def send_password_reset_email(user):
token = user.get_reset_password_token()
send_email(_('[Microblog] Reset Your Password'),
sender=current_app.config['ADMINS'][0],
recipients=[user.email],
text_body=render_template('email/reset_password.txt',
user=user, token=token),
html_body=render_template('email/reset_password.html',
user=user, token=token))
def send_async_email(app, msg):
with app.app_context():
mail.send(msg)
def send_email(subject, sender, recipients, text_body, html_body):
msg = Message(subject, sender=sender, recipients=recipients)
msg.body = text_body
msg.html = html_body
Thread(target=send_async_email,
args=(current_app._get_current_object(), msg)).start()
In routes.py file im getting email from the user and if the user email match then i well send the token to the user via mail
@bp.route('/reset_password_request', methods=['GET', 'POST'])
def reset_password_request():
if current_user.is_authenticated:
return redirect(url_for('main.index'))
form = ResetPasswordRequestForm()
if form.validate_on_submit():
user = User.query.filter_by(email=form.email.data).first()
if user:
send_password_reset_email(user)
flash(
_('Check your email for the instructions to reset your password'))
return redirect(url_for('auth.login'))
return render_template('auth/reset_password_request.html',
title=_('Reset Password'), form=form)
@bp.route('/reset_password/<token>', methods=['GET', 'POST'])
def reset_password(token):
if current_user.is_authenticated:
return redirect(url_for('main.index'))
user = User.verify_reset_password_token(token)
if not user:
return redirect(url_for('main.index'))
form = ResetPasswordForm()
if form.validate_on_submit():
user.set_password(form.password.data)
db.session.commit()
flash(_('Your password has been reset.'))
return redirect(url_for('auth.login'))
return render_template('auth/reset_password.html', form=form)
In model.py file in the user model i generate a token for a user and also check the user token
def get_reset_password_token(self, expires_in=600):
return jwt.encode(
{'reset_password': self.id, 'exp': time() + expires_in},
current_app.config['SECRET_KEY'],
algorithm='HS256').decode('utf-8')
@staticmethod
def varify_reset_password_token(token):
try:
id = jwt.decode(token, current_app.config['SECRET_KEY'],
algorithms=['HS256'])['reset_password']
except:
return
return User.query.get(id)
my flask mail setup is as follows config.py file
MAIL_SERVER = os.environ.get('MAIL_SERVER')
MAIL_PORT = int(os.environ.get('MAIL_PORT') or 25)
MAIL_USE_TLS = os.environ.get('MAIL_USE_TLS') is not None
MAIL_USERNAME = os.environ.get('MAIL_USERNAME')
MAIL_PASSWORD = os.environ.get('MAIL_PASSWORD')
ADMINS =['socialtraffic@gmail.com']
The following Error i get in the terminal
