高德地图api实现地址和经纬度的转换(python)

利用高德地图web服务api实现地理/逆地址编码

api使用具体方法请查看官方文档

1.利用python第三方库requests实现

Requests库文档地址：http://www.python-requests.org/en/master/

 #!/usr/bin/env python3
 #-*- coding:utf-8 -*-

 import requests

 def geocode(address):
         parameters = {'address': address, 'key': 'cb649a25c1f81c1451adbeca73623251'}
         base = 'http://restapi.amap.com/v3/geocode/geo'
         response = requests.get(base, parameters)
         answer = response.json()
         print(address + "的经纬度：", answer['geocodes'][0]['location'])

 if __name__=='__main__':
         #address = input("请输入地址:")
         address = '北京市海淀区'
         geocode(address)

2.基于http协议利用标准库http.client实现

 #!/usr/bin/env python3
 #-*- coding:utf-8 -*-

 import http.client
 import json
 from urllib.parse import quote_plus

 base = '/v3/geocode/geo'
 key  = 'cb649a25c1f81c1451adbeca73623251'

 def geocode(address):
         path = '{}?address={}&key={}'.format(base, quote_plus(address), key)
         #print(path)
         connection = http.client.HTTPConnection('restapi.amap.com',80)
         connection.request('GET', path)
         rawreply = connection.getresponse().read()
         #print(rawreply)
         reply = json.loads(rawreply.decode('utf-8'))
         print(address + '的经纬度：',reply['geocodes'][0]['location'])

 if __name__=='__main__':
         #address = input("请输入你的地址：")
         address = '北京市朝阳区'
         geocode(address)

3.利用基于传输层上socket实现

 #!/usr/bin/env python3
 #-*- coding:utf-8 -*-

 import socket
 from urllib.parse import quote_plus

 request_text = """\
 GET /v3/geocode/geo?address={}&key=cb649a25c1f81c1451adbeca73623251 HTTP/1.1\r\n\
 Host: restapi.amap.com:80\r\n\
 User-Agent: search4.py\r\n\
 Connection: close\r\n\
 \r\n\
 """

 def geocode(address):
         sock = socket.socket()
         sock.connect(('restapi.amap.com', 80))
         request = request_text.format(quote_plus(address))
         sock.sendall(request.encode('ascii'))
         raw_reply = b''
         while True:
                 more = sock.recv(4096)
                 if not more:
                         break
                 raw_reply += more
         print(raw_reply.decode('utf-8'))

 if __name__=='__main__':
         #address = input("请输入地址：")
         address = '北京市朝阳区'
         geocode(address)
