Usage

The service is used to generate QR-codes for strings in a UNIX/Linux console using curl/httpie/wget or similar tools.

The service can be used in a browser also. Just add qrenco.de/ before the URL.

The service uses libqrencode to generate QR-codes.

Installation

You don't need to install the service for using it (just try curl qrenco.de), but if you want to install it locally, do the following steps:

macOS

$ brew install qrencode

or

$ sudo port install qrencode

Debian/Ubuntu

$ sudo apt-get install qrencode python-virtualenv

Fedora >= 22

$ sudo dnf install qrencode python2-virtualenv

Common Steps

$ git clone https://github.com/chubin/qrenco.de
$ cd qrenco.de
$ virtualenv ve
$ ve/bin/pip install -r requirements.txt
$ ve/bin/python bin/srv.py

If you want to use a HTTP-frontend for the service, configure it this way:

server {
    listen 80;
    listen [::]:80;
    server_name  qrenco.de *.qrenco.de;
    access_log  /var/log/nginx/qrenco.de-access.log;
    error_log  /var/log/nginx/qrenco.de-error.log;

    location / {
        proxy_pass         http://127.0.0.1:8003;

        proxy_set_header   Host             $host;
        proxy_set_header   X-Real-IP        $remote_addr;
        proxy_set_header   X-Forwarded-For  $remote_addr;

        client_max_body_size       10m;
        client_body_buffer_size    128k;

        proxy_connect_timeout      90;
        proxy_send_timeout         90;
        proxy_read_timeout         90;

        proxy_buffer_size          4k;
        proxy_buffers              4 32k;
        proxy_busy_buffers_size    64k;
        proxy_temp_file_write_size 64k;

        expires                    off;
    }

}
