get 请求，
1，获取文章标签 ，
2，拿到前台传来的值，
3，根据前台传来的值在数据库中查询
4.，返回数据到前台，渲染，
分页算法 ：
在 utils 下创建 paginator_script.py
def get_paginator_data(paginator, current_page, around_count=3):
"""
:param paginator: 分页对象
:param current_page: 当前页数据

左边页码范围、右边页码范围
"""

total_page_num = paginator.num_pages # 获取总页数
left_has_more_page = False # 默认左边没有更多页
right_has_more_page = False # 默认右边没有更多页
# 算出当前页面左边的页码
