尝试使用TimedJSONWebSignatureSerializer使令牌过期时出错，以重置密码

如何解决尝试使用TimedJSONWebSignatureSerializer使令牌过期时出错，以重置密码

我已经在线阅读了要过期的令牌，我必须使用expires_in。但是，我无法使其正常工作。

s = TimedJSONWebSignatureSerializer('secretkey',expires_in = 1)

@app.route('/reset',methods=['GET','POST'])
def reset():
    msg = ''
    if request.method == 'POST' and 'email' in request.form:
        global email
        email = request.form['email']
        cursor = MysqL.connection.cursor(MysqLdb.cursors.DictCursor)
        cursor.execute('SELECT * FROM accounts WHERE email = %s',(email,))
        account = cursor.fetchone()

        if account:
            print(account)
            token = (s.dumps([account]))
            sender_email = 'email'
            recipient = account['email']
            password = 'password'

            message = f"""
Your password reset link:
{url_for('reset_token',token=token,_external=True)}
"""
            server = smtplib.SMTP('smtp.gmail.com',587)
            server.starttls()
            server.login(sender_email,password)
            server.sendmail(sender_email,recipient,message)
        else:
            msg = 'Failed'
    return render_template('reset.html',msg=msg)


@app.route("/reset_password/<token>",'POST'])
def reset_token(token):
    if current_user.is_authenticated:
        return redirect(url_for('home'))

    form2 = ResetPasswordForm()
    if form2.validate_on_submit():
        form2password = form2.confirm_password.data
        cursor = MysqL.connection.cursor(MysqLdb.cursors.DictCursor)
        sqlupdate = ('UPDATE accounts SET password = %s WHERE email = %s')
        value = (form2password,email)
        cursor.execute(sqlupdate,value)
        MysqL.connection.commit()
        flash('Your password has been updated! You are Now able to log in','success')
        return redirect(url_for('login'))
    return render_template('reset_token.html',title='Reset Password',form=form2)

我已经确认可以发送电子邮件并且可以更改密码。我面临的问题是，发送的电子邮件重置链接没有过期并且仍然可以使用，我不知道该如何解决。我看过在线示例和文档，但是它们非常模糊。

我希望密码重置链接在5分钟/ 300秒后失效。
