如何在Python中获取Geoclue地理位置？-什么是桌面id参数？

Question

我正在尝试使用GeoClue for Linux和Python接口(gir1.2-geoclue-2.0包)获取位置(经度/经度)。documentation for c几乎与这里的api函数匹配，但是我不确定我应该发送什么“桌面id”……应用程序所请求的任何有效.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)

(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)
__main__:1: Warning: g_object_unref: assertion 'object->ref_count > 0' failed
<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。在获取笔记本电脑/设备的大致位置时，我是否错过了一个步骤？据我所知，它应该能够以类似于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获得大致位置，

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

但是第一个参数应该是什么呢？什么是“桌面id"?？

Answer 1

虽然我不确定这个参数应该是什么，但我已经在Python中实现了它。完整的解释可以在here上找到。

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'))
