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/
1 #!/usr/bin/env python3 2 #-*- coding:utf-8 -*- 3 ''' 4 利用高德地图api实现地址和经纬度的转换 5 ''' 6 import requests 7 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
1 #!/usr/bin/env python3 2 #-*- coding:utf-8 -*- 3 ''' 4 利用高德地图api实现地址和经纬度的转换 5 ''' 6 7 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\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("请输入地址：") 30 address = '北京市朝阳区' 31 geocode(address)
