如何使用 Google API 从具有坐标的数据集中获取地址？

Question

数据集有9975个经纬度。我想提取地址。我写了下面的代码：

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'])

我遇到的错误：

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:]

你用的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 Google 地图 JavaScript API 的地理编码服务的内部调用。你不应该使用内部 URLs，使用官方网络服务调用。

查看 Geocoding API 文档并将 URL 替换为记录的反向地理编码 URL:

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

我认为您遇到了 403 错误，因为您请求中的令牌已过期。此令牌由 Maps JavaScript API 生成，因此您应该使用网络服务调用来解决问题。

请注意，Web 服务限制为每秒 50 次查询。

此外，我建议您看看 Python Client for Google Maps Services。使用此库，您可以轻松地对坐标进行反向地理编码

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]))

希望对您有所帮助！
