Question

我正在尝试使用 Google API 和 json 信息从查询中获取地址信息。但是我只得到最终商品的地址，而不是汇总的地址。如何在 python 中解决此问题？

我的代码由3部分组成： 1.从json文件（sample.json）中提取纬度和经度信息。 2.使用Google API查询地址 3.从查询结果中提取地址（json格式）并写入文件（test.csv）

首先，我的输入json文件（sample.json）如下：

{"last_updated":1554148141,
"ttl":10,
"data":{"stations":
[{"station_id":"1","external_id":"0b0fda98-08f3-11e7-a1cb-3863bb33a4e4","name":"Métro Champ-de-Mars (Viger / Sanguinet)","short_name":"6001","lat":45.51035067563653,"lon":-73.55650842189789,"rental_methods":["CREDITCARD","KEY"],"capacity":33,"electric_bike_surcharge_waiver":false,"eightd_has_key_dispenser":false,"has_kiosk":true},

{"station_id":"2","external_id":"0b0fdf05-08f3-11e7-a1cb-3863bb33a4e4","name":"Ste-Catherine / Dezery","short_name":"6002","lat":45.539385081961676,"lon":-73.54099988937377,"rental_methods":["CREDITCARD","KEY"],"capacity":19,"electric_bike_surcharge_waiver":false,"eightd_has_key_dispenser":false,"has_kiosk":true},

{"station_id":"3","external_id":"0b0fe114-08f3-11e7-a1cb-3863bb33a4e4","name":"Clark / Evans","short_name":"6003","lat":45.51100666600306,"lon":-73.56760203838348,"rental_methods":["CREDITCARD","KEY"],"capacity":19,"electric_bike_surcharge_waiver":false,"eightd_has_key_dispenser":false,"has_kiosk":true}
 ] } }

接下来是我在python中的代码：（API_KEY是我的个人密钥，因此标记为“ ****”。）

import json
import requests
import csv


input_json = json.load(open('sample.json'))
for i in input_json ['data']['stations']:
    lat = i['lat']
    lon = i['lon']

API_URL = "https://maps.googleapis.com/maps/api/geocode/json?latlng={},{}&formatted_address&result_type=street_address&key=".format(
    lat, lon)
API_KEY = '***********'

try:

     response = requests.get(API_URL+API_KEY, auth=('user','pass'))
     data = response.json()
     address = []
     for i in data['results']:
         a = i['formatted_address']
         address.append(a)
         f = csv.writer(open('test.csv', 'w'))
         f.writerow(address)

except Exception as e:
         print(e)
else:
         print(address)

运行此代码时，结果如下：

['2025 Rue Clark, Montréal, QC H2X 2R6, Canada', '2026 Rue Clark, Montréal, QC H2X 1Y8, Canada']

根据Google查询，结果应显示总共6个地址（每个项目2个地址）。我的结果仅显示最后一项的2个地址。

我不知道如何适当地编码循环部分。您能帮我解决这个问题吗？

如何使用Google API从查询中获取汇总结果？
