如何使chrome使用会话总线代替系统总线
如何使chrome使用会话总线代替系统总线
提问于 2021-08-20 23:54:01
我试图让chrome在docker容器上使用会话dbus，而不是系统总线，但到目前为止失败了。我尝试过以下几种方法：
Xvfb $DISPLAY -screen 0 1920x1080x24 -pn -noreset >> /tmp/xvfb.log 2>&1 &
export $(dbus-launch)
google-chrome --no-sandbox --no-first-runXvfb $DISPLAY -screen 0 1920x1080x24 -pn -noreset >> /tmp/xvfb.log 2>&1 &
dbus-run-session -- google-chrome --no-sandbox --no-first-run在这两种情况下，都设置了DBUS_SESSION_BUS_ADDRESS，但看起来chrome忽略了它并尝试连接到/var/run/dbus/system_bus_socket

看起来/var/run/dbus/system_bus_socket是硬编码在chrome的源代码中的，所以我需要做以下事情：
#!/bin/sh
export DISPLAY=":1"
start_xvfb() {
[ -e "/tmp/.X1-lock" ] && rm -f /tmp/.X1-lock
nohup Xvfb :1 -screen 0 1920x1080x24 -pn -noreset >> /tmp/xvfb.log 2>&1 &
echo $!
}
XVFB_PID="$(start_xvfb)"
echo -e "[startup] xvfb started with PID $XVFB_PID"
sleep 1
# make dbus visible to other processes
mkdir -p /var/run/dbus/
export DBUS_STARTER_BUS_TYPE="session"
export DBUS_STARTER_ADDRESS="unix:path=/var/run/dbus/system_bus_socket"
export DBUS_SESSION_BUS_ADDRESS="unix:path=/var/run/dbus/system_bus_socket"
unset DBUS_SESSION_BUS_PID
unset DBUS_SESSION_BUS_WINDOWID
# open unix socket for dbus, on common setups it's done by systemd
python -c "import socket; s = socket.socket(socket.AF_UNIX); s.bind('/var/run/dbus/system_bus_socket')"
# start it
dbus-daemon --session --nofork --nosyslog --nopidfile --address=$DBUS_STARTER_ADDRESS >> /tmp/dbus.log 2>&1 &
returncode=$?
DBUS_PID=$!
[ $returncode -ne 0 ] && exit $returncode
echo -e "[startup] dbus started with PID $DBUS_PID"
sleep 1
google-chrome --no-sandbox --no-first-run
returncode=$?
kill $XVFB_PID
kill $DBUS_PID
sleep 1
exit $returncode在记录了那个chrome之后：
