1.利用python第三方庫requests實現

Requests庫文檔地址：http://www.python-requests.org/en/master/

 1 #!/usr/bin/env python3 2 #-*- coding:utf-8 -*- 3 ‘‘‘ 4 利用高德地圖api實現地址和經緯度的轉換 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 = ‘北京市海澱區‘18         geocode(address)

 

2.基於http協議利用標準庫http.client實現

 1 #!/usr/bin/env python3 2 #-*- coding:utf-8 -*- 3 ‘‘‘ 4 利用高德地圖api實現地址和經緯度的轉換 5 ‘‘‘ 6  7  8 import http.client 9 import json10 from urllib.parse import quote_plus11 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\n10 User-Agent: search4.py\r\n11 Connection: close\r\n12 \r\n13 """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                         break25                 raw_reply += more26         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)
