如何在Python中获取地理位置线索？什么是桌面id参数？

Question

我正在尝试使用GeoClueforLinux和Python接口（gir1.2-geoclue-2.0包）获取位置（lat/lon）。documentation for c几乎与这里的api函数匹配，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)

(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/设备的一般位置时，我是否遗漏了一个步骤？据我所知，这应该能够以类似whatsmyip.com的方式从网络上读取设备的位置

更新：通过与返回值交互，我可以获得大致位置

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

但是第一个参数应该是什么？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中使用了它。有完整的解释here

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'))
