python - Python - Folium 的搜索插件给出错误

问题描述

我在python中使用folium.Search()。但是，当我运行我的代码时，代码返回一个错误。如何解决这个问题？

import folium
from folium import plugins    
import json


m = folium.Map(location=[39.92370048 , 32.85271525],zoom_start=12)    
with open('3596566.json') as f:    
    data = json.load(f)

plugins.Search(data,position='topright',                  
               search_zoom=20,
               search_label='ParselNo',
               geom_type="Polygon").add_to(m)

m.save('map.html')

错误是：

Traceback (most recent call last):
  File "C:/Users/HP/proje/ödev2.py", line 17, in <module>
    geom_type="Polygon").add_to(m)

  File "C:\Python36\lib\site-packages\folium\plugins\search.py", line 100, in __init__
    ), 'Search can only index FeatureGroup, ' \

AssertionError: Search can only index FeatureGroup, MarkerCluster, GeoJson, and TopoJson layers at this time.

解决方案

我按如下方式修复了这个错误。我将 GeoJson 文件转移到了一个变量中。

points ={
  "type": "FeatureCollection",
  "features": [
{
  "type": "Feature",
  "geometry": {
    "type": "Polygon",
    "coordinates": [

          32.73575,
          39.85949

          39.85928

        [
          32.73684,
          39.85925
        ]
      ]
    ]
  },

geojson_obj = folium.GeoJson(points).add_to(m)

plugins.Search(geojson_obj,position='topleft',
                           search_zoom=17,
                           search_label='ParselNo',
                           geom_type='Polygon').add_to(m)
