python中的地理编码器服务错误

Question

我在尝试从 geopy 运行地理编码器以在 python 中获取位置坐标时遇到服务错误。我已经设置了代理配置，给它一个 api_key。 我不确定为什么会收到此错误。从我对此进行的搜索来看，这似乎是一个代理问题，但我已经设置好了。 这可能是什么问题？

这是我的代码：

from geopy import geocoders

proxies={'http': 'http://location:port', 'https': 'http://localhost:port'}
api_key = '.......'

g = geocoders.GoogleV3(api_key=api_key,proxies=proxies, timeout=10)

location = 'Mountain View, CA'
try:
    place, (lat, lng) = g.geocode(location)
except ValueError as error_message:
    print("Error: geocode failed on input %s with message %s" % (location, error_message))

这是我的错误输出：

我修改了您的代码如下，因为我不使用代理并应用 API，它在我的机器上工作。

from geopy import geocoders

#proxies={'http': 'http://location:port', 'https': 'http://localhost:port'}
#api_key = '.......'

g = geocoders.GoogleV3()

location = 'Mountain View, CA'
try:
    place, (lat, lng) = g.geocode(location)
except ValueError as error_message:
    print("Error: geocode failed on input %s with message %s" % (location, error_message))

print (place, lat, lng)

这是结果。

从 trackback 看来，所有错误都与 SSL 有关。您可以尝试在开头添加以下代码以禁用 SSL 认证验证。

import ssl 

# Disable SSL certificate verification
try:
    _create_unverified_https_context = ssl._create_unverified_context
except AttributeError:
    # Legacy Python that doesn't verify HTTPS certificates by default
    pass
else:
    # Handle target environment that doesn't support HTTPS verification
    ssl._create_default_https_context = _create_unverified_https_context

我在运行 Python 3.6 的 env 中运行 Python 2.7 的 Anaconda 中遇到了类似的问题，而 root 运行 Python 3.6。在 Anaconda 中没有遇到此问题，root 和 env 在另一台机器上运行 Python 2.7。

另外，this SO post关于使用os模块为geopy设置代理服务器可能是很好的参考。

希望对您有所帮助。
