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（纬度/经度）。c的文档几乎与此处的 api 函数匹配，但我不确定我应该发送什么“桌面 ID”......任何有效.desktop的文件是应用程序请求的？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)

(process:7691): Geoclue-WARNING **: Error setting property 'RequestedAccuracyLevel' 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 object at 0x7f4fde2ad8b8 (GClueSimple at 0x1b89340)>
>>> Geoclue.Simple.new_sync('something',Geoclue.AccuracyLevel.NEIGHBORHOOD,None)

最后一个命令挂起，不返回任何内容。我是否错过了获取笔记本电脑/设备大致位置的步骤？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。此处提供了完整的解释。

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'))
