Spotify Unity快速清单

如何为Spotify（从他们的网站安装）添加Unity“快速列表”，以便当我右键单击扩展坞上的图标时，我得到：“下一个，上一个，停止，播放”等等？

spotify（本地linux客户端）

由于Spotify包含用于控制其某些功能的指示器，因此这使我们可以使用它dbus来发送事件。

在ubuntuforums上有一个很棒的脚本可以解决这个问题。

首先安装先决条件：

sudo apt-get install libnet-dbus-perl

现在，将脚本复制并粘贴到一个名为的文本文件中spcmd，并将其保存到您的主文件夹中。

赋予它执行权：

chmod +x ~/spcmd

让我们将其移动到更有用的文件夹中：

mv ~/spcmd /usr/local/bin

现在，让我们创建一个快速列表。

首先将spotify桌面文件复制到您的主文件夹中：

mkdir -p ~/.local/share/applications
cp /usr/share/applications/spotify.desktop ~/.local/share/applications

打开文件，然后将快速列表复制并粘贴到文件末尾。保存。

gedit ~/.local/share/applications/spotify.desktop

最终结果

sub set_DBUS_SESSION_BUS_ADDRESS {
my $curruser = `whoami`; chomp $curruser;
my $procname = 'spotify';
my $pid = `pgrep -o -u $curruser $procname`; chomp $pid;
my $environ = '/proc/' . $pid . '/environ';
my $dbussession = `grep -z DBUS_SESSION_BUS_ADDRESS $environ`; $dbussession =~ s/^DBUS_SESSION_BUS_ADDRESS=//;

$ENV{'DBUS_SESSION_BUS_ADDRESS'} = $dbussession;
}

我认为到目前为止给出的答案有些复杂。不需要单独的脚本，可以通过直接发送相关的DBus命令dbus-send。只需确保dbus已安装该软件包，然后在命令行中发出以下命令：

mkdir -p ~/.local/share/applications
cp /usr/share/applications/spotify.desktop ~/.local/share/applications/

编辑文件~/.local/share/applications/spotify.desktop以读取：

[Desktop Entry]

Exec=spotify %U
TryExec=spotify

[Desktop Action PlayPause]
Name=Play/Pause
Exec=dbus-send --print-reply=literal --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.PlayPause
OnlyShowIn=Messaging Menu;Unity;

[Desktop Action Next]
Name=Next
Exec=dbus-send --print-reply=literal --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.Next
OnlyShowIn=Messaging Menu;Unity;

[Desktop Action Previous]
Name=Previous
Exec=dbus-send --print-reply=literal --dest=org.mpris.MediaPlayer2.spotify /org/mpris/MediaPlayer2 org.mpris.MediaPlayer2.Player.Previous

这样就完成了。

spotify_cmd是用于控制wine下正在运行的Spotify实例的工具 ，它也应在Windows上运行，但尚未经过测试。

下载spotifycmd。复制到桌面。然后

cd ~/Desktop/
tar -xvjf spotifycmd-0.5.tar.bz2 
sudo cp -r spotifycmd /usr/bin/

现在Exec=/usr/bin/spotifycmd/spotify_cmd.exe XXXX在创建快速列表时使用。

这里XXXX是playpause，next，prev，stop，voldown，volup，等。

Spotify将在面板上显示一个图标。只需单击该按钮，即可播放，停止，暂停，下一个等等（不记得全部）。不确定是否能回答您的问题。
