Question

您好我有以下json文件，其中包含拉斯维加斯6000家餐厅的信息，例如：“名称”，“经度”，“纬度”。我想使用“经度”创建地图和地图标签标签，“ “每个点的纬度”并在地图中显示每个餐厅的“名称”。我使用pycharm和python 3.6.5（32位）。我尝试导入folium库，它可以工作，但它不显示名称地图中的每家餐馆。如何在地图中显示每家餐厅的名称？提前致谢！

json文件yelp_restaurant_Las_Vegas是：

{ 
"_id" : ObjectId("5a9eb7b2a2f96c346024f239"), 
"city" : "Las Vegas", 
"neighborhood" : "Southeast", 
"name" : "Flight Deck Bar & Grill", 
"business_id" : "Pd52CjgyEU3Rb8co6QfTPw", 
"longitude" : -115.1708484, 
"hours" : {
    "Monday" : "8:30-22:30", 
    "Tuesday" : "8:30-22:30", 
    "Friday" : "8:30-22:30", 
    "Wednesday" : "8:30-22:30", 
    "Thursday" : "8:30-22:30", 
    "Sunday" : "8:30-22:30", 
    "Saturday" : "8:30-22:30"
}, 
"state" : "NV", 
"postal_code" : "89119", 
"categories" : [
    "Nightlife", 
    "Bars", 
    "Barbeque", 
    "Sports Bars", 
    "American (New)", 
    "Restaurants"
], 
"stars" : 4.0, 
"address" : "6730 S Las Vegas Blvd", 
"latitude" : 36.0669136, 
"review_count" : NumberInt(13), 
"is_open" : NumberInt(1), 
  .
  .
  .

代码为：

from pymongo import MongoClient
import pandas as pd
import folium
from IPython.display import HTML
client = MongoClient("localhost",27017)

db = client.Desktop
collection1 =db.yelp_restaurant_Las_Vegas
reviews=pd.DataFrame(list(collection1.find()))


mapi_osm = folium.Map(location=())
reviews.apply(lambda row:folium.CircleMarker(location[row["latitude"],row["longitude"]]).add_to(mapi_osm),axis=1)

mapi_osm.save('spst.html')

将弹出窗口添加到标记中。

如果你想让它们自动打开，你需要来自github的最新的folium（因为pypi上的版本不够新）。几周前，通过show参数支持传单的openPopup调用。如果您不关心它们是否被自动打开则无关紧要（只需删除Popup构造函数的show参数）。

pip install git+https://github.com/python-visualization/folium.git

reviews.apply(lambda row:folium.CircleMarker(
          location=[row["latitude"],row["longitude"]],
          popup=Popup(row['name'],show=True)).add_to(mapi_osm),axis=1)

这是一个最小的例子：

import folium
from folium.map import Popup

m = folium.Map(location=())
folium.CircleMarker(location=(36.112625, -115.176704), popup=Popup('Picasso', show=True)).add_to(m)
m.save('map.html')
