調(diào)用百度地圖api呈現(xiàn)熱力圖
數(shù)據(jù)來源，wordpress博客的訪問，百度網(wǎng)盤https://pan.baidu.com/s/1slqbCZF 提取碼 dv6f
ip采集插件:SlimStat；
使用百度ip定位api將ip轉(zhuǎn)化為經(jīng)緯度坐標(biāo),也寫成json文件,
import urllib
import time
IpList = open("ip_add_all.json","r").read()
Ip = eval(IpList)
flag = 0
file = open('point.json’,’a’)
for i in range(len(Ip)):
ip = Ip[i]['ip']
res = urllib.request.urlopen("http://api.map.baidu.com/location/ip?ak=KrmZxHHwvLnl4Xfyt0FMMVzgGLaaxU2j&ip="+ip+"&coor=bd09ll")
a = res.read()
zidian = eval(a)
flag += 1
if(zidian['status'] == 0):
print(flag,ip)
lng = zidian['content']['point']['x']
lat = zidian['content']['point']['y']
str_temp = '{"lat": '+lat+', "lng":'+lng+'},\n'
file.write(str_temp)
file.close()
另外我也將得到的.json文件轉(zhuǎn)化為了.csv文件，都在百度云上
修改里面的point數(shù)組,則可以將之前采集的點(diǎn)呈現(xiàn)上去,

import pandas as pd
data = pd.read_csv('points.cv')
for i in range(len(data)):
print('{' + '\"lng\":' + str(data.iloc[i][2])[:-2] +',\"lat\":' + str(data.iloc[i][1])[:-2] + ',\"count\":' + str(int(data.iloc[i][3])) + '}') # 將數(shù)據(jù)轉(zhuǎn)化成需要的格式
