如果我有一组坐标，我怎样才能得到国家，只有请求库？

Question

我需要获取一组坐标来自的国家/地区：示例：

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 requests 库。(json 也可用）谢谢

正如@Razdi 所说，您将需要一个 API 获取您的坐标和 returns 一个位置。

这叫做reverse geocoding。

将 Requests 库想象成浏览器 URL 路径。它所能做的就是获取网站地址。但是，如果地址是正确的，并且需要某些参数，那么您可以访问值：

>>> 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：

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

但是你不能使用这个包...所以你需要更详细一点：

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']

If I have a set of coordinates, how can I get the country, only with the Requests library?

python

request

geolocation

python-3.x

python-requests
