raspotify-nginx-restart

This project addresses an issue from librespot that sometimes loses authentication and needs to be restarted in order to re-authenticate.

I am using raspotify on a dedicated raspberry pi and needed a way to easily restart raspotify when it loses connection, without ssh.

So I can now do a POST request to /restart-raspotify on my raspotify device and it will restart (and re-authenticate to spotify).

Components

• Daemon (as root) that actually restarts the raspotify service
• Nginx small lua script that writes 1 to a file (/etc/restart-raspotify)

Dependencies

• python3
• nginx
• nginx-extras (for the lua script)

Install

On the Raspberry Pi, get the files with either:

git clone https://github.com/cristi8/raspotify-nginx-restart.git
cd raspotify-nginx-restart

or

wget https://github.com/cristi8/raspotify-nginx-restart/archive/master.zip
unzip master.zip
cd raspotify-nginx-restart-master

To install the daemon:

cd daemon
make install

To install the nginx part, copy/edit this location block to the nginx site config that you want to use:

    location /restart-raspotify {
        ## Optional: Set up nginx access control like allow only some source ip addresses or set up basicauth

        ## Optional: Only allow POST requests
        # if ( $request_method != POST ) { return 405; }

        default_type application/json;
        content_by_lua '
            local file = assert(io.open("/etc/restart-raspotify", "w"), "Inaccessible file")
            file:write("1")
            file:close()
            ngx.say("{\\"success\\": 1}")
        ';
    }

Uninstall

To uninstall the daemon:

cd daemon
make uninstall

And then remove the /restart-raspotify location from nginx config.
