Lua:将使用xmldbus定义发出消息的Python代码翻译成Lua
我是在评论之前的一个问题时问这个问题的,但我认为最好把它作为一个新的独立问题转移到这里 我试图找出如何使用lgi dbus将此Python代码转换为Lua,以发出dbus信号:Lua:将使用xmldbus定义发出消息的Python代码翻译成Lua,lua,dbus,lgi,Lua,Dbus,Lgi,我是在评论之前的一个问题时问这个问题的,但我认为最好把它作为一个新的独立问题转移到这里 我试图找出如何使用lgi dbus将此Python代码转换为Lua,以发出dbus信号: class DBUSTestInterface(object): """ Server_XML definition.

但我不确定,我也不知道如何使用Python中的XML设置消息体
如果你能提供一些例子或指出我在哪里可以找到它,我将不胜感激
谢谢 嘿,谷歌带我来这里看看 不知何故,我觉得您的代码示例不能像一些自包含的python代码那样工作。因此,我将采用文本中的评论: 每秒发射/发布一个随机整数信号
LUA代码,除了“随机整数”之外,除非您考虑<代码> 42 /代码>是随机的:
local object = "/org/freedesktop/DBus"
local interface = "org.freedesktop.DBus.Introspectable"
local method = "Introspect"
local message = Gio.DBusMessage.new_method_call(name, object, interface, method)
message:set_body(GLib.Variant("(aoo)", {{location},session})) -- How do I set the same message as above?
local lgi = require("lgi")
local Gio, GLib, GObject = lgi.Gio, lgi.GLib, lgi.GObject
local conn
GLib.timeout_add_seconds(GLib.PRIORITY_DEFAULT, 1, function()
if conn then
conn:emit_signal(nil, "/your/example/has/no/path",
"com.test.device.aaa", "get",
GLib.Variant("(sssssssi)", { "what", "are", "all",
"these", "strings", "for", "?", 42 }))
end
return true
end)
local function on_bus_acquire(con)
conn = con
local function arg(name, signature)
return Gio.DBusArgInfo{ name = name, signature = signature }
end
local interface_info = Gio.DBusInterfaceInfo {
