#通过地址获取经纬度的三种方法
#方法一  http://www.cnblogs.com/liangto/p/6287957.html中的方法二
import urllib2
import json

address =\'西安市高新区锦业路69号创业研发园\'
url = \'http://api.map.baidu.com/geocoder/v2/?address=%s\'% address + \'&output=json&ak=秘钥\'
html = urllib2.urlopen(url)
json1 = html.read() #转化为str类型
hjson1 =json.loads(json1) #转化为dict类型
lng1 = hjson1[\'result\'][\'location\'][\'lng\']  # 经度
lat1 = hjson1[\'result\'][\'location\'][\'lat\']  # 纬度
print \'方法一:\',lng1,lat1


#方法二   http://blog.csdn.net/mrlevo520/article/details/52556625
import requests

base =  \'http://api.map.baidu.com/geocoder/v2/?address=西安市高新区锦业路69号创业研发园&output=json&ak=秘钥\'
response = requests.get(base)
answer = response.json()
lng = answer[\'result\'][\'location\'][\'lng\']
lat = answer[\'result\'][\'location\'][\'lat\']
print \'方法二:\',lng,lat
#反查
baseop = \'http://api.map.baidu.com/geocoder/v2/?ak=秘钥&location=39.911013, 116.413554&output=json\'
responseop = requests.get(baseop)
answerop = responseop.json()
province = answerop[\'result\'][\'addressComponent\'][\'province\']
city = answerop[\'result\'][\'addressComponent\'][\'city\']
print \'方法二反查:\',province,city

#方法三   http://blog.csdn.net/spacecraft/article/details/43309447
from geopy.geocoders import baidu

apikey = \'秘钥\'  # 从网站申请 http://lbsyun.baidu.com/apiconsole/key?application=key
b = baidu.Baidu(apikey)
location = b.geocode("西安市高新区锦业路69号创业研发园")
print \'方法三:\',location.longitude,location.latitude
#反查
aa = b.reverse("22.546834, 113.946787")
ad = aa.address
p_start = ad.index(\'省\')
p_end = ad.index(\'市\')
print \'方法三反查:\',ad[:p_start+3],ad[p_start+3:p_end+3]
