用Django+Json对百度地图进行标点（项目）可将经纬度转化为地址_django 国内地址地图 免费地图插件

1、先绘制一张中国大地图：可展示中国大致的疫情情况

2、大地图可跳转至各个省份

3、当大地图跳转至重庆，进入百度地图

4、对【小镭】经过的点进行标记

点击省份【四川】，可进入四川省份地图，双击退回全国地图

 点击省份【重庆】，输入要查询的姓名 ，如【小镭】，提交后进入百度地图

可查看到【小镭】经过了两个地点（坐标），并在百度地图上显示

 划过跳动的标记点，可查看详细信息

 

思路：

用户在前端输入要查询的数据，表单提交到后台，后台进行判断，如果传过来的数据能匹配到后台列表里的【姓名】，则返回对应的姓名的【坐标列表】，若没有则返回【查询不到信息】。

（1）配置URL

from django.conf.urls import url
from demo import views
from django.urls import path
 
urlpatterns = [
    url(r'^T/$', views.home, name='demo'),
]

（2）定义视图函数

获取前端表单提交的数据，后台对传过来的姓名进行搜索，再将对应的坐标数据传给前端
