高德地圖api實現地址和經緯度的轉換(python)

利用高德地圖web服務api實現地理/逆地址編碼

api使用具體方法請查看官方文檔

1.利用python第三方庫requests實現

 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 + "的經緯度：", answer['geocodes'][0]['location'])
14 
15 if __name__=='__main__':
16         #address = input("請輸入地址:")
17         address = '北京市海淀區'
18         geocode(address)

 

2.基於http協議利用標準庫http.client實現

 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 + '的經緯度：',reply['geocodes'][0]['location'])
24 
25 if __name__=='__main__':
26         #address = input("請輸入你的地址：")
27         address = '北京市朝陽區'
28         geocode(address)

 

3.利用基於傳輸層上socket實現

 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\r\n\
 9 Host: restapi.amap.com:80\r\n\
10 User-Agent: search4.py\r\n\
11 Connection: close\r\n\
12 \r\n\
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("請輸入地址：")
30         address = '北京市朝陽區'
31         geocode(address)
