Question

我正在运行一个适用于套接字的脚本..它需要sudo才能运行.. 然而，在脚本内部，我调用另一个不需要以sudo身份运行的脚本

这是代码：

import subprocess
import socket
s=socket.socket(socket.AF_INET, socket.SOCK_STREAM)
#s.settimeout(5.0)
host='192.168.1.148'
port=1022
s.bind((host, port))
s.listen(5)
while True:
    c, addr = s.accept()
    subprocess.call("python bluetooth2.py",shell=True)
    print 'got connection from',addr
    c.send('Thank you for connecting')
    #c.settimeout(5.0)
    c.recv(1022)
    c.close()

bluetooth2.py运行pulseaudio，由于某种原因以root身份运行并且不起作用。任何帮助非常感谢！

以下是bluetooth2.py脚本的参考信息（调用pulseaudio的那个）

import time
import pexpect
from sh import bluetoothctl
import subprocess
mac = "C8:84:47:26:E6:3C"
print ("stuck here")
#bluetoothctl("connect", mac)

def connect():
    child = pexpect.spawn('bluetoothctl')
    child.sendline('power on')
    child.sendline('agent on')
    child.sendline('default-agent')
    child.sendline('pair C8:84:47:26:E6:3C')
    time.sleep(1)
    child.sendline('trust C8:84:47:26:E6:3C')
    time.sleep(1)
    child.sendline('connect C8:84:47:26:E6:3C')
    print("connecting...")
    time.sleep(5)
    subprocess.call("pulseaudio --start",shell=True)
    subprocess.call("pacmd set-default-sink
    bluez_sink.C8_84_47_26_E6_3C",shell=True)
    subprocess.call("aplay /home/pi/bleep_01.wav", shell=True)

解决方案为所有用户运行 PulseAudio

将波纹管添加到/etc/systemd/system/pulseaudio.service文件并保存

[Unit]
Description=PulseAudio system server

[Service]
Type=notify
ExecStart=pulseaudio --daemonize=no --system --realtime --log-target=journal

[Install]
WantedBy=multi-user.target
Enable service

sudo systemctl --system enable pulseaudio.service
sudo systemctl --system start pulseaudio.service
sudo systemctl --system status pulseaudio.service

Edit Client conf /etc/pulse/client.conf 并替换下面的屁股

default-server = /var/run/pulse/native
autospawn = no

将根添加到脉冲组

sudo adduser root pulse-access

最后重启系统

Pulseaudio和Python中的sudo
