我想通过谷歌方向API动态查询谷歌地图。例如，这个请求计算了从伊利诺伊州芝加哥到加利福尼亚州洛杉矶的路线，途经密苏里州乔普林和俄克拉荷马城的两个路点，OK:
http://maps.googleapis.com/maps/api/directions/json?origin=Chicago,IL&destination=Los+Angeles,CA&waypoints=Joplin,MO|Oklahoma+City,OK&sensor=false
它返回JSON格式的结果。
如何在Python中做到这一点?我想发送这样一个请求，接收结果并解析它。

Requests有内置的.json()方法
import requests
requests.get(url).json()

Requests有内置的.json()方法
import requests
requests.get(url).json()
import urllib
import json
url = 'http://maps.googleapis.com/maps/api/directions/json?origin=Chicago,IL&destination=Los+Angeles,CA&waypoints=Joplin,MO|Oklahoma+City,OK&sensor=false'
result = json.load(urllib.urlopen(url))
试试这个:
import requests
import json
# Goole Maps API.
link = 'http://maps.googleapis.com/maps/api/directions/json?origin=Chicago,IL&destination=Los+Angeles,CA&waypoints=Joplin,MO|Oklahoma+City,OK&sensor=false'
# Request data from link as 'str'
data = requests.get(link).text
# convert 'str' to Json
data = json.loads(data)
# Now you can access Json
for i in data['routes'][0]['legs'][0]['steps']:
lattitude = i['start_location']['lat']
longitude = i['start_location']['lng']
print('{}, {}'.format(lattitude, longitude))
只需导入请求并使用json()方法:
source = requests.get("url").json()
print(source)
或者你可以用这个:
import json,urllib.request
data = urllib.request.urlopen("url").read()
output = json.loads(data)
print (output)
我推荐使用很棒的请求库:
import requests
url = 'http://maps.googleapis.com/maps/api/directions/json'
params = dict(
origin='Chicago,IL',
destination='Los+Angeles,CA',
waypoints='Joplin,MO|Oklahoma+City,OK',
sensor='false'
)
resp = requests.get(url=url, params=params)
data = resp.json() # Check the JSON Response Content documentation below
