为什么我的地理位置不起作用？

Question

我的职责是计算我的公司到任何地址的距离（最后（打印函数）我放了一个地址的例子））。我不知道为什么它不起作用，它说明了回溯错误。

我的函数的第一部分，从地址转换为坐标。 第二部分计算距离。

这是密码

import math
from geopy.geocoders import Nominatim

def Distancia(direccion_domicilio):
    geolocator = Nominatim(user_agent="specify_your_app_name_here")
    location = geolocator.geocode(direccion_domicilio)
    latylon=(location.latitude, location.longitude)


    rad=math.pi/180
    dif_lat = 20.6072848-(latylon[0])
    dif_long = -103.4160099-(latylon[1])
    radio=6372.795477598
    a=(math.sin(rad*dif_lat/2))**2 + math.cos(rad*location.latitud)*math.cos(rad*20.6072848)*(math.sin(rad*dif_long/2)**2)
    distancia=2*radio*math.asin(math.sqrt(a))
    return distancia

print(Distancia("Avenida Guadalupe, Real Guadalupe, Jardines de Chapalita, Zapopan, Jalisco, 45030, México"))

这是错误消息

您没有执行整个安装过程。 Traceback 告诉你发生了什么。它说 SSL 证书有问题。 geopy 库从网络检索数据（在您的情况下为 Nomitatiom）。 查看此文档：https://geopy.readthedocs.io/en/stable/#geopy.geocoders.options 和名为 default_ssl_context 的选项。 您应该在代码的开头使用此代码（来自上述文档）：

• 使用 SSL 使用：

导入 ssl 进口证明 导入 geopy.geocoders ctx = ssl.create_default_context(cafile=certifi.where()) geopy.geocoders.options.default_ssl_context = ctx

• 禁用 SSL（不推荐，甚至可能不适用于某些地理提供商）：

导入 ssl 导入 geopy.geocoders ctx = ssl.create_default_context() ctx.check_hostname = 假 ctx.verify_mode = ssl.CERT_NONE geopy.geocoders.options.default_ssl_context = ctx
