如果我有一组坐标，如何仅使用请求库获取国家/地区?

Question

我需要获取一组坐标来自的国家/地区： 例：

coords=[41.902782, 12.496366.]

output:
Italy

我知道这可以通过使用其他库来实现，但我需要知道是否有办法只使用请求库来完成。(JSON也可用) 谢谢。

正如@Razdi所说，您将需要一个获取坐标并返回位置的 API。

这称为反向地理编码。

将请求库视为浏览器 URL 路径。它所能做的就是获取网站的地址。但是，如果地址正确，并且需要某些参数，则可以访问值：

>>> import requests
>>> url = 'https://maps.googleapis.com/maps/api/geocode/json'
>>> params = {'sensor': 'false', 'address': 'Mountain View, CA'}
>>> r = requests.get(url, params=params)
>>> results = r.json()['results']
>>> location = results[0]['geometry']['location']
>>> location['lat'], location['lng']

你想要的是这样的东西：

import geocoder
g = geocoder.google([45.15, -75.14], method='reverse')

但是您不能使用该软件包...所以你需要更详细：

导入请求

def example():
# grab some lat/long coords from wherever. For this example,
# I just opened a javascript console in the browser and ran:
#
# navigator.geolocation.getCurrentPosition(function(p) {
#   console.log(p);
# })
#
latitude = 35.1330343
longitude = -90.0625056
# Did the geocoding request comes from a device with a
# location sensor? Must be either true or false.
sensor = 'true'
# Hit Google's reverse geocoder directly
# NOTE: I *think* their terms state that you're supposed to
# use google maps if you use their api for anything.
base = "http://maps.googleapis.com/maps/api/geocode/json?"
params = "latlng={lat},{lon}&sensor={sen}".format(
lat=latitude,
lon=longitude,
sen=sensor
)
url = "{base}{params}".format(base=base, params=params)
response = requests.get(url)
return response.json()['results'][0]['formatted_address']
