一百一十一：CMS系统之后端权限验证功能

实现方式

使用装饰器的形式，将权限判断加在视图上

声明接口需要什么权限，用户访问接口的时候，判断用户是否有此权限

权限判断，接收权限

def permission_required(permission):
    def outter(func):
        @wraps(func)
        def inner(*args, **kwargs):
            user = g.cms_user
            if user.has_permission(permission):
                return func(*args, **kwargs)
            else:
                return redirect(url_for('cms.index'))

        return inner

    return outter

声明接口需要的权限

@bp.route('/posts/')
@login_required
@permission_required(CMSPersmission.POSTER)
def posts():
    return render_template('cms/cms_posts.html')

@bp.route('/comments/')
@login_required
@permission_required(CMSPersmission.COMMENTER)
def comments():
    return render_template('cms/cms_comments.html')

@bp.route('/boards/')
@login_required
@permission_required(CMSPersmission.BOARDER)
def boards():
    return render_template('cms/cms_boards.html')

@bp.route('/fusers/')
@login_required
@permission_required(CMSPersmission.FRONTUSER)
def fusers():
    return render_template('cms/cms_fusers.html')

@bp.route('/cusers/')
@login_required
@permission_required(CMSPersmission.CMSUSER)
def cusers():
    return render_template('cms/cms_cusers.html')
