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 %}
