Listen on a port and serve QR codes encoding data from the path or the request body.
For example, if running on localhost and port 5000, then both of the following are supported ways to generate a QR code encoding the string "hello-there":
curl http://localhost:5000/hello-therecurl -d 'hello-there' http://localhost:5000If the path following the hostname is non-empty, that will be used as the data to encode, and the request body will be ignored.
By default, listens on port 5000. To listen on another port, use
sudo snap set qr-server port=<port>, with <port> being any available
port number.
Both GET and POST requests are accepted and may be used interchangeably.

Snaps are applications packaged with all their dependencies to run on all popular Linux distributions from a single build. They update automatically and roll back gracefully.
Snaps are discoverable and installable from the Snap Store, an app store with an audience of millions.
Snap is available for CentOS 7.6+, and Red Hat Enterprise Linux 7.6+, from the Extra Packages for Enterprise Linux (EPEL) repository. The EPEL repository can be added to your system with the following command:
sudo yum install epel-release
Snap can now be installed as follows:
sudo yum install snapd
Once installed, the systemd unit that manages the main snap communication socket needs to be enabled:
sudo systemctl enable --now snapd.socket
To enable classic snap support, enter the following to create a symbolic link between /var/lib/snapd/snap and /snap:
sudo ln -s /var/lib/snapd/snap /snap
Either log out and back in again, or restart your system, to ensure snap’s paths are updated correctly.
To install QR Server, simply use the following command:
sudo snap install qr-server
Browse and find snaps from the convenience of your desktop using the snap store snap.
