I have created a simple http server on mininet simple topology host h1 using the following command
h1 python3 -m SimpleHTTPSErver 80 &
and then tried to connect h2 to h1 by using
h2 wget -O - h1
but the connection is refused
Python3 does not have the SimpleHTTPServer module anymore. It has been deprecated and replaced by http.server. I assume you have not looked at the output of these commands.
I have successfully ran the example
python3 -m http.server 80
on h1. And was then able to connect h2 to it using h1's IP address as follows:
wget -O - 10.0.0.1
