python中通过mod_wsgi连接Dbus

发布于 2024-09-30 13:50:09 字数 1533 浏览 1 评论 0原文

我正在尝试编写一个小型应用程序，它允许通过网页发送 dbus 命令（到 Amarok）。
我使用 python + mod_wsgi，因为我需要使用与 Amarok 相同的用户运行脚本。

当我通过普通 shell 连接到 Amarok 时，它可以工作。但通过脚本连接后，出现以下错误：

DBusException: org.freedesktop.DBus.Error.Spawn.ExecFailed: /usr/bin/dbus-launch terminated abnormally with the following error: Autolaunch error: X11 initialization failed.

The code which isconnecting to the Amarok:

import dbus
conn = dbus.SessionBus().get_object('org.kde.amarok','/Player')

Do you Know how should I do to connect through dbus to Amarok?
非常感谢您的帮助！

更新：我将为您提供一些有关配置的附加信息：

httpd.conf：

LoadModule wsgi_module  modules/mod_wsgi.so
WSGIScriptAlias /amarok /var/www/amarok-python/config.wsgi
WSGIDaemonProcess l user=wojtas group=wojtas processes=1
WSGIProcessGroup l

config.WSGI：

import sys
path='/var/www/amarok-python'
if path not in sys.path:
    sys.path.append(path)
import index
application=index.application

应用程序代码（index.py）：

import dbus
from os import getuid
def connect():
        conn = dbus.SessionBus().get_object('org.kde.amarok','/Player')
        conn.Start()
        return conn
def application(environ,start_response):
    status= '200 OK'
    connection=connect()
    output=str(getuid())
    response_headers= [('Content-type','text/html'), ('Content-Length', str(len(output)))]
    start_response (status,response_headers)
    return [output]

原文

I'm trying to write small application which allows to send dbus commands (to Amarok) through web page.
I'm using python + mod_wsgi, because I need to run the script with the same user as Amarok.

When I connect to the Amarok through normal shell, it works. But after connecting through the script, I get the following error:

DBusException: org.freedesktop.DBus.Error.Spawn.ExecFailed: /usr/bin/dbus-launch terminated abnormally with the following error: Autolaunch error: X11 initialization failed.

The code which is connecting to the Amarok:

import dbus
conn = dbus.SessionBus().get_object('org.kde.amarok','/Player')

Do you know what should I do to connect through dbus to Amarok?
Thanks a lot for help!

Update:
I'll give you some additional information about configuration:

httpd.conf:

LoadModule wsgi_module  modules/mod_wsgi.so
WSGIScriptAlias /amarok /var/www/amarok-python/config.wsgi
WSGIDaemonProcess l user=wojtas group=wojtas processes=1
WSGIProcessGroup l

config.WSGI:

import sys
path='/var/www/amarok-python'
if path not in sys.path:
    sys.path.append(path)
import index
application=index.application

Code of the application (index.py):

import dbus
from os import getuid
def connect():
        conn = dbus.SessionBus().get_object('org.kde.amarok','/Player')
        conn.Start()
        return conn
def application(environ,start_response):
    status= '200 OK'
    connection=connect()
    output=str(getuid())
    response_headers= [('Content-type','text/html'), ('Content-Length', str(len(output)))]
    start_response (status,response_headers)
    return [output]
