wget --no-check-certificate

I got into some minor trouble when following the tutorial, but I can easily fix it with --no-check-certificate

# add another layer as POST data not working
if [ ! -f "ne_50m_populated_places.geojson" ]; then
  wget --no-verbose https://d2ad6b4ur7yvpq.cloudfront.net/naturalearth-3.3.0/ne_50m_populated_places.geojson
fi
curl --silent -d @ne_50m_populated_places.geojson http://localhost:8090/qgis/addVectorLayer?name=geojson-layer

# add another layer as POST data, fixed
if [ ! -f "ne_50m_populated_places.geojson" ]; then
  wget --no-verbose --no-check-certificate https://d2ad6b4ur7yvpq.cloudfront.net/naturalearth-3.3.0/ne_50m_populated_places.geojson
fi
curl --silent -d @ne_50m_populated_places.geojson http://localhost:8090/qgis/addVectorLayer?name=geojson-layer

By the way as you surely know, wget is not in MacOS by default. Everything goes fine after that, thanks.
