我正在嘗試創(chuàng)建一個帶有建筑物的對開頁地圖。我想根據(jù)每個建筑物的相應屬性向其添加一個彈出窗口。但是，我編寫的代碼會向所有建筑物添加相同的彈出窗口。openbare_ruimte我已經咨詢了有關此問題的幾個線程（#1023，#1060，#popups，#popups2），但無法使其正常工作。有誰知道如何將每個建筑物的屬性添加到其彈出窗口中？openbare_ruimteimport jsonimport requestsimport foliumurl = "http://geodata.nationaalgeoregister.nl/bag/wfs?service=wfs&version=2.0.0&request=GetFeature&outputFormat=json&count=25&srsName=epsg:4326&typeName=bag:verblijfsobject&cql_filter=%28bag:woonplaats=%27Groningen%27%29"js_data = json.loads(requests.get(url).text)m = folium.Map(location=[53.2193835, 6.5665018], zoom_start=13)fg = folium.map.FeatureGroup(name='Buildings').add_to(m)#Add the polygons features to the FeatureGroup layerfor feature in js_data['features']: fg.add_child(folium.GeoJson(feature['properties']['pandgeometrie']))#Add popups to the FeatureGroup layerfor feature in js_data['features']: fg.add_child(folium.Popup(feature['properties']['openbare_ruimte']))folium.LayerControl().add_to(m)m

如果我理解正確，您希望每個建筑物都提供一個顯示其地址（我想是街道）的彈出窗口。
此代碼似乎可以執(zhí)行您想要的操作：
import json
import requests
import folium
url = "http://geodata.nationaalgeoregister.nl/bag/wfs?service=wfs&version=2.0.0&request=GetFeature&outputFormat=json&count=25&srsName=epsg:4326&typeName=bag:verblijfsobject&cql_filter=%28bag:woonplaats=%27Groningen%27%29"
js_data = json.loads(requests.get(url).text)
m = folium.Map(location=[53.2193835, 6.5665018], zoom_start=13)
fg = folium.map.FeatureGroup(name='Buildings').add_to(m)
for feature in js_data['features']:
b = folium.GeoJson(feature['properties']['pandgeometrie'])
b.add_child(folium.Popup(feature['properties']['openbare_ruimte']))
fg.add_child(b)
folium.LayerControl().add_to(m)
m
