lws minimal dbus server
build
Using libdbus requires additional non-default include paths setting, same as is necessary for lws build described in ./lib/roles/dbus/README.md
CMake can guess one path and the library name usually, see the README above for details of how to override for custom libdbus and cross build.
Fedora example:
$ cmake .. -DLWS_DBUS_INCLUDE2="/usr/lib64/dbus-1.0/include"
$ make
Ubuntu example:
$ cmake .. -DLWS_DBUS_INCLUDE2="/usr/lib/x86_64-linux-gnu/dbus-1.0/include"
$ make
usage
Commandline option | Meaning |
---|---|
-d | Debug verbosity in decimal, eg, -d15 |
--session | Bind to session bus instead of creating private abstract unix socket |
By default the minimal server listens using its own abstract unix socket
at unix:abstract=org.libwebsockets.test
.
You can also run it instead as a participant on the session bus, without its own
unix socket, by giving --session
.
Examples using the default private abstract unix socket
$ ./lws-minimal-dbus-server
[2018/10/03 07:08:02:6448] USER: LWS minimal dbus server
[2018/10/03 07:08:02:6693] NOTICE: Creating Vhost 'default' port 0, 1 protocols, IPv6 off
...
You can communicate with the dbus server over its private abstract socket using, eg
$ gdbus introspect --address unix:abstract=org.libwebsockets.test --dest org.libwebsockets.test --object-path /org/libwebsockets/test
node /org/example/TestObject {
interface org.freedesktop.DBus.Introspectable {
methods:
Introspect(out s data);
signals:
properties:
};
interface org.freedesktop.DBus.Properties {
methods:
Get(in s interface,
...
$ gdbus call --address unix:abstract=org.libwebsockets.test --dest org.libwebsockets.test --object-path /org/libwebsockets/test --method org.libwebsockets.test.Echo HELLO
('HELLO',)
Examples using the DBUS session bus
$ ./lws-minimal-dbus-server --session
[2018/10/03 07:08:02:6448] USER: LWS minimal dbus server
[2018/10/03 07:08:02:6693] NOTICE: Creating Vhost 'default' port 0, 1 protocols, IPv6 off
...
You can communicate with the dbus server over the session bus using, eg
$ gdbus introspect --session --dest org.libwebsockets.test --object-path /org/libwebsockets/test
node /org/example/TestObject {

methods:
Introspect(out s data);
signals:
properties:
};
interface org.freedesktop.DBus.Properties {
methods:

$ gdbus call --session --dest org.libwebsockets.test --object-path /org/libwebsockets/test --method org.libwebsockets.test.Echo HELLO
('HELLO',)
