本文介绍了将结构传递给dbus方法的工具?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我创建了一个守护进程。守护程序提供了一个dbus接口,其方法之一具有诸如(uu)这样的签名-这是两个 uint32 字段。

I've created a daemon. The daemon provides a dbus interface, with one of its methods having a signature like this (uu) -- that is a struct of two uint32 fields.

有没有现成的工具可供我调用方法,传递结构? dbus发送 d-feet 似乎没有帮助。

Is there a ready-to-use tool for me to invoke the method, to pass the struct in? dbus-send and d-feet doesn't seem to help.

任何指针吗?

推荐答案

gdbus 应该招。尝试执行以下操作:

gdbus should do the trick. Try the equivalent of:

gdbus call --session --dest com.example.MyTest  --object-path /com/example/MyTest --method com.example.MyTest.Test "(1,2)"

。 ..具有适合您情况的正确参数。

... with the correct parameters for your situation of course.

我已经使用Python D-Bus服务测试了上面的调用,如下所示:

I've tested the call above using a Python D-Bus service like this:

import gobject
import dbus
import dbus.service

from dbus.mainloop.glib import DBusGMainLoop
DBusGMainLoop(set_as_default=True)


OPATH = "/com/example/MyTest"
IFACE = "com.example.MyTest"
BUS_NAME = "com.example.MyTest"


class Example(dbus.service.Object):
    def __init__(self):
        bus = dbus.SessionBus()
        bus.request_name(BUS_NAME)
        bus_name = dbus.service.BusName(BUS_NAME, bus=bus)
        dbus.service.Object.__init__(self, bus_name, OPATH)

    @dbus.service.method(dbus_interface=IFACE,
                         in_signature="(uu)", out_signature="")
    def Test(self, payload):
        print "Got this from client:", payload


if __name__ == "__main__":
    service = Example()
    loop = gobject.MainLoop()
    loop.run()

在Ubuntu 15.10计算机上,我在 gdbus 上由<$ c $提供c> libglib2.0-bin 软件包:

On the Ubuntu 15.10 machine I'm on gdbus is provided by the libglib2.0-bin package:

$ dpkg -L libglib2.0-bin | grep gdbus
/usr/bin/gdbus
/usr/share/bash-completion/completions/gdbus
/usr/share/man/man1/gdbus.1.gz

希望这会有所帮助。
