Question

我正在使用Flask开发此电子邮件确认应用程序。为此，我正在使用flask_mail（显然），但出现此错误：

TypeError：“邮件”类型的参数不可迭代

@app.route('/email', methods=['GET', 'POST'])
def send_mail():
    getting = request.form.get('mail')
    token = s.dumps(getting, salt='email-confirm')

    msg = Message('Confirm Email', sender='vatsalayvk1434@gmail.com', recipients=[mail])

    link = url_for('confirm_mail', token=token, _externel=True)
    msg.body = f'Your Link is {link}'

    mail.send(msg)
    return render_template('confirm.html', getting=getting, token=token)

这是模板代码

                    <input type="submit" class="btn btn-outline-primary mt-4 ml-3">
                </form>
            </div>
            <h2>The Mail is  : {{getting}}</h2>
            <h2>The token is : {{token}}</h2>
    </div>

</body>
</html>

Answer 1

您将错误的值传递给了收件人。

这里：

@app.route('/email', methods=['GET', 'POST'])
def send_mail():
    getting = request.form.get('mail')
    token = s.dumps(getting, salt='email-confirm')

    msg = Message('Confirm Email', sender='vatsalayvk1434@gmail.com', recipients=[mail])

    link = url_for('confirm_mail', token=token, _externel=True)
    msg.body = f'Your Link is {link}'

    mail.send(msg)
    return render_template('confirm.html', getting=getting, token=token)

您传递到了收件人参数中，该参数中包含一个带有 mail 变量的列表，而不是要将邮件发送到的电子邮件地址的列表。我假设您正在将Mail对象传递给收件人。

我假设您要发送电子邮件的地址位于获取变量中。

解决方案：

@app.route('/email', methods=['GET', 'POST'])
def send_mail():
    getting = request.form.get('mail')
    token = s.dumps(getting, salt='email-confirm')

    # msg = Message('Confirm Email', sender='vatsalayvk1434@gmail.com', recipients=[getting])
    # To send the mail to yourself
    msg = Message('Confirm Email', sender='vatsalayvk1434@gmail.com', recipients=['vatsalayvk1434@gmail.com'])

    link = url_for('confirm_mail', token=token, _externel=True)
    msg.body = f'Your Link is {link}'

    mail.send(msg)
    return render_template('confirm.html', getting=getting, token=token)
