pyngrok
pyngrok is a Python wrapper for ngrok that manages its own binary and puts it on your path, making ngrok readily available from anywhere on the command line and via a convenient Python API.
ngrok is a reverse proxy tool that opens secure tunnels from public URLs to localhost, perfect for exposing local web servers, building webhook integrations, enabling SSH access, testing chatbots, demoing from your own machine, and more, and its made even more powerful with native Python integration through pyngrok.
Installation
pyngrok
is available on PyPI and can be installed
using pip
:
pip install pyngrok
or conda
:
conda install -c conda-forge pyngrok
That's it! pyngrok
is now available as a package to our Python projects, and ngrok
is now available from
the command line.
Basic Usage
To open a tunnel, use the connect
method,
which returns a NgrokTunnel
, and this returned object has a reference to the public URL generated by ngrok
in its
public_url
attribute.
from pyngrok import ngrok
# Open a HTTP tunnel on the default port 80
# <NgrokTunnel: "http://<public_sub>.ngrok.io" -> "http://localhost:80">
http_tunnel = ngrok.connect()
# Open a SSH tunnel
# <NgrokTunnel: "tcp://0.tcp.ngrok.io:12345" -> "localhost:22">
ssh_tunnel = ngrok.connect(22, "tcp")
The connect
method takes kwargs
as
well, which allows us to pass additional properties that are supported by ngrok.
This package puts the default ngrok
binary on our path, so all features of ngrok
are
available on the command line.
ngrok http 80
For details on how to fully leverage ngrok
from the command line, see ngrok's official documentation.
Documentation
For more advanced usage, pyngrok
's official documentation is available at http://pyngrok.readthedocs.io.
Python 2.7
The last version of pyngrok
that supports Python 2.7 is 4.1.x, so we need to pin pyngrok>=4.1,<4.2
if we still want
to use pyngrok
with this version of Python. Its legacy documentation can be found here.
