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/

 6 import requests

 8 def geocode(address):
 9         parameters = {'address': address, 'key': 'cb649a25c1f81c1451adbeca73623251'}
10         base = 'http://restapi.amap.com/v3/geocode/geo'
11         response = requests.get(base, parameters)
12         answer = response.json()
13         print(address + "的经纬度：", answer['geocodes'][0]['location'])
14 
15 if __name__=='__main__':
16         #address = input("请输入地址:")
17         address = '北京市海淀区'
18         geocode(address)

2.基于http协议利用标准库http.client实现

 8 import http.client
 9 import json
10 from urllib.parse import quote_plus
11 
12 base = '/v3/geocode/geo'
13 key  = 'cb649a25c1f81c1451adbeca73623251'
14 
15 def geocode(address):
16         path = '{}?address={}&key={}'.format(base, quote_plus(address), key)
17         #print(path)
18         connection = http.client.HTTPConnection('restapi.amap.com',80)
19         connection.request('GET', path)
20         rawreply = connection.getresponse().read()
21         #print(rawreply)
22         reply = json.loads(rawreply.decode('utf-8'))
23         print(address + '的经纬度：',reply['geocodes'][0]['location'])
24 
25 if __name__=='__main__':
26         #address = input("请输入你的地址：")
27         address = '北京市朝阳区'
28         geocode(address)

3.利用基于传输层上socket实现

 1 #!/usr/bin/env python3
 2 #-*- coding:utf-8 -*-
 3 
 4 import socket
 5 from urllib.parse import quote_plus
 6 
 7 request_text = """
 8 GET /v3/geocode/geo?address={}&key=cb649a25c1f81c1451adbeca73623251 HTTP/1.1

 9 Host: restapi.amap.com:80

10 User-Agent: search4.py

11 Connection: close

12 

13 """
14 
15 def geocode(address):
16         sock = socket.socket()
17         sock.connect(('restapi.amap.com', 80))
18         request = request_text.format(quote_plus(address))
19         sock.sendall(request.encode('ascii'))
20         raw_reply = b''
21         while True:
22                 more = sock.recv(4096)
23                 if not more:
24                         break
25                 raw_reply += more
26         print(raw_reply.decode('utf-8'))
27 
28 if __name__=='__main__':
29         #address = input("请输入地址：")
30         address = '北京市朝阳区'
31         geocode(address)
