Flask-mail发送邮件详细步骤及出现的错误

  这一周的时间，有点空余都在继续学习flask web，其中flask-mail这一节，算是最大的一个坑了吧！我将一步步把大家从坑里拉出来!

一、首先，将邮箱换成163的

app.config['MAIL_SERVER'] = 'smtp.163.com'
app.config['MAIL_PORT'] = 465
app.config['MAIL_USE_SSL'] = True

二、设置环境变量

set MAIL_USERNAME=[e-mail]
set MAIL_PASSWORD=xxxx

是的，我不知道在什么地方，足足坑了我两天！

一开始，我在PyCharm的Terminal中设置，不行！！

后来，我又在cmd命令下设置，但是每回重启又不行了，呵呵！

最后，在我的电脑-右键-属性-高级系统设置-环境变量，将MAIL_USERNAME等设置

 

三、设置163邮箱POP3/SMTP/IMAP,如果不设置，将有如下错误：

 

  File "D:\PycharmProjects\hello\venv\lib\site-packages\flask_mail.py", line 165, in configure_host
    host.login(self.mail.username, self.mail.password)
  File "E:\Python36\Lib\smtplib.py", line 730, in login
    raise last_exception
  File "E:\Python36\Lib\smtplib.py", line 721, in login
    initial_response_ok=initial_response_ok)
  File "E:\Python36\Lib\smtplib.py", line 642, in auth
    raise SMTPAuthenticationError(code, resp)
smtplib.SMTPAuthenticationError: (550, b'User has no permission')

 

四、在工程中templates文件夹下新建mail文件夹，新建new_user.html，内容为

User <b>{{ user.username }}</b> has joined.

五、最后，上部分hello.py的代码

 

app.config['MAIL_USERNAME'] = os.environ.get('MAIL_USERNAME')
app.config['MAIL_PASSWORD'] = os.environ.get('MAIL_PASSWORD')
app.config['FLASKY_MAIL_SUBJECT_PREFIX'] = '[Flasky]'
app.config['FLASKY_MAIL_SENDER'] ='Flasky Admin <[e-mail]>'
app.config['FLASKY_ADMIN'] = os.environ.get('FLASKY_ADMIN')

def send_email(to, subject, template, **kwargs):
    msg = Message(app.config['FLASKY_MAIL_SUBJECT_PREFIX']+subject,
sender=app.config['FLASKY_MAIL_SENDER'], recipients=[to])
    msg.body = render_template(template + '.txt', **kwargs)
    msg.html = render_template(template + '.html', **kwargs)
    mail.send(msg)

 

@app.route('/', methods=['GET', 'POST'])
def index():
    form = NameForm()
    if form.validate_on_submit():
        # old_name = session.get('name')
user = User.query.filter_by(username=form.name.data).first()
        if user is None:
            user = User(username=form.name.data)
            db.session.add(user)
            session['known'] = False
# if app.config['FLASKY_ADMIN']:
send_email(app.config['FLASKY_ADMIN'], 'New User', 'mail/new_user', user=user)
        else:
            session['known'] = True
session['name'] = form.name.data
        form.name.data = ''
# send_email(app.config['FLASKY_ADMIN'], 'New User')
        # send_email(app.config['FLASKY_ADMIN'], 'New User', 'mail/new_user', user=user)
return redirect(url_for('index'))
    return render_template('index.html', form=form, name=session.get('name'), known=session.get('known', False))

if __name__ == '__main__':
    app.run(debug=True)
    # manager.run()

运行，发送成功！
