如何在Python中获取地理位置线索什么是桌面id参数？

我正在尝试使用GeoClueforLinux和Python接口（

gir1.2-GeoClue-2.0

package）获取位置（lat/lon）。这里的api函数几乎匹配，但我不确定应该发送什么“桌面id”。。。应用程序请求的任何有效的

.desktop

文件？？完整路径或唯一名称

>>> Geoclue.Simple.new.__doc__
'new(desktop_id:str, accuracy_level:Geoclue.AccuracyLevel, cancellable:Gio.Cancellable=None, callback:Gio.AsyncReadyCallback=None, user_data=None)'
>>> Geoclue.Simple.new_sync('hi',Geoclue.AccuracyLevel.NEIGHBORHOOD,None)

但是第一个参数应该是什么？什么是“桌面id”？

虽然我不确定这一参数应该是什么，但我已经在Python中使用了它。有完整的解释

谢谢你写这篇文章…非常方便！

c = Geoclue.Simple.new_sync('something',Geoclue.AccuracyLevel.NEIGHBORHOOD,None)

from gi.repository import Geoclue
clue = Geoclue.Simple.new_sync('something',Geoclue.AccuracyLevel.NEIGHBORHOOD,None)
location = clue.get_location()
print(location.get_property('latitude'), location.get_property('longitude'))
