3.1.cms用户名渲染和注销功能实现

显示登录的用户名

（1）app/cms/hooks.py

from .views import bp

import config

from flask import session,g

from .models import CMSUser

@bp.before_request

def before_request():

    if config.CMS_USER_ID in session:

        user_id = session.get(config.CMS_USER_ID)

        user = CMSUser.query.get(user_id)

        if user:

            g.cms_user = user

（2）app/cms/init.py

要导入一下才可以，否则不会执行hooks.py里面的代码

import apps.cms.hooks

（3）cms/cms_index.html

<li><a href="#">{{ g.cms_user.username }}<span>[超级管理员]</span></a></li>

注销功能

cms/views.py

@bp.route('/logout/')

@login_required

def logout():

    del session[config.CMS_USER_ID]

    return redirect(url_for('cms.login'))

cms/cms_index.html

 <li><a href="{{ url_for('cms.logout') }}">注销</a></li>

3.2.cms模板抽离和个人信息页面完成

（1）cms/cms_base.html

{% from "common/_macros.html" import static %}

<!DOCTYPE html>

    <meta charset="UTF-8">

    <title>{% block title %}{% endblock %}</title>
