我正在尝试使用适用于Linux的GeoClue和Python接口(gir1.2-geoclue-2.0包(获取位置(lat/lon(。c 的文档几乎与这里的 api 函数相匹配，但我不确定我应该发送什么"桌面 ID"......应用程序请求的任何有效.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)
(process:7691): Geoclue-WARNING **: Error setting property 'DesktopId' on interface org.freedesktop.GeoClue2.Client: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: No such interface 'org.freedesktop.DBus.Properties' on object at path /org/freedesktop/GeoClue2/Client/2 (g-dbus-error-quark, 19)

>>> Geoclue.Simple.new_sync('something',Geoclue.AccuracyLevel.NEIGHBORHOOD,None)
最后一个命令挂起，不返回任何内容。我是否缺少获取笔记本电脑/设备的大致位置的步骤？据我了解，这应该能够以类似于 whatsmyip.com 的方式从网络中读取设备的位置？
更新：我能够通过与返回值交互来获得粗略的位置，
c = Geoclue.Simple.new_sync('something',Geoclue.AccuracyLevel.NEIGHBORHOOD,None)
但是第一个参数应该是什么？什么是"桌面 ID"？？
虽然我不确定那个参数应该是什么，但我已经让它在 Python 中工作了。完整的解释可在此处获得。
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'))
