关于python：如何使用Google API从具有坐标的数据集中获取地址？

How to get addresses from dataset having coordinates using Google API?

数据集有9975个纬度和经度。我想提取地址。我写了以下代码：

import numpy as np
from bs4 import BeautifulSoup
import urllib.request
import json

coordinates=coordinates.as_matrix()
address=[]
for i in range(len(coordinates)):
qpage = 'https://maps.googleapis.com/maps/api/js/GeocodeService.Search?5m2&1d'+str(coordinates[i][0])+'&2d'+str(coordinates[i][1])+'&7sUS&9sen&callback=_xdc_._jhwtgt&key=MY_API_KEY&token=53066'
page = urllib.request.urlopen(qpage)
data = page.read().decode('utf-8').replace('(','[').replace(')',']')
data=data[34:]
js = json.loads(data)
address.append(js[0]['results'][1]['formatted_address'])

我得到的错误是：

HTTPError Traceback (most recent call
last) in ()
8 for i in range(len(coordinates)):
9 qpage = 'https://maps.googleapis.com/maps/api/js/GeocodeService.Search?5m2&1d'+str(coordinates[i][0])+'&2d'+str(coordinates[i][1])+'&7sUS&9sen&callback=xdc._jhwtgt&key=MY_API_KEY&token=53066'
---> 10 page = urllib.request.urlopen(qpage)
11 data = page.read().decode('utf-8').replace('(','[').replace(')',']')
12 data=data[34:]

任何帮助都将不胜感激。

您使用的URL

'https://maps.googleapis.com/maps/api/js/GeocodeService.Search?5m2&1d'+str(coordinates[i][0])+'&2d'+str(coordinates[i][1])+'&7sUS&9sen&callback=_xdc_._jhwtgt&key=YOUR_API_KEY&token=53066'

这是来自GoogleMapsJavaScriptAPI的地理编码服务的内部调用。您不应该使用内部URL，使用官方的Web服务调用。

查看geocoding api文档，并用文档化的反向geocoding url替换url：

'https://maps.googleapis.com/maps/api/geocode/json?latlng='+str(coordinates[i][0])+'%2C'+str(coordinates[i][1])+'&key=YOUR_API_KEY。

我相信您收到403错误，因为您请求中的令牌已过期。这个令牌是由maps javascript api生成的，所以您应该使用Web服务调用来解决这个问题。

请注意，Web服务限制为每秒50个查询。

另外，我建议您看看GoogleMaps服务的python客户端。使用这个库，您可以轻松地对坐标进行地理编码。

import googlemaps

coordinates=coordinates.as_matrix()
gmaps = googlemaps.Client(key='YOUR_API_KEY')

for i in range(len(coordinates)):
reverse_geocode_result = gmaps.reverse_geocode((coordinates[i][0], coordinates[i][1]))

希望这有帮助！
