TecoRoute Proxy
TecoRoute Proxy is a reverse proxy server that allows easy authentication to the
TecoRoute service using a simple POST request. It also saves the credentials
and automatically logs the user in when the TecoRoute session expires.
How it works
The server has one control endpoint (/TR_PROXY by default) that is used
to log in and log out of the user from the proxy. All other requests are proxied
to TecoRoute. The proxy session is stored only in the user's session cookies, so
the server is completely stateless and no database is required.
The control endpoint accepts POST requests with
application/x-www-form-urlencoded content type (HTML form).
Log the user in
The user logs in with the following data:

Name
Value

action
login

username
TecoRoute username

password
TecoRoute password

plc
TecoRoute PLC

Example of a HTML form that logs the user in:
<form method="post" action="https://tecoroute-proxy.cze.tech/TR_PROXY">
<button name="action" value="login">Open PLC</button>
<input type="hidden" name="username" value="BroukPytlik" />
<input type="hidden" name="password" value="ferda1" />
<input type="hidden" name="plc" value="AB_1234" />
</form>

Log the user out
The user logs out with the following data:

Name
Value

action
logout

Example of a HTML form that logs the user out:
<form method="post" action="https://tecoroute-proxy.cze.tech/TR_PROXY">
<button name="action" value="logout">Logout from TecoRoute</button>
</form>

Logging out will try to log the user out from TecoRoute and delete the login
data from the user's cookies.
Usage options
TecoRoute Proxy can be used as a service, standalone application or as a Python
library.
Use as a service
Server is deployed at https://tecoroute-proxy.cze.tech. The control URL is:
https://tecoroute-proxy.cze.tech/TR_PROXY

Feel free to use the service for testing or simple production purposes.
Install from PyPI
Requirements:

Python (version 3.8 or later)
pip or another package installer for Python

Installation using pip is done with:

For all options, run tecoroute-proxy --help.
It is possible to use the package as a Python library and run the server
synchronously or asynchronously in the event loop. Example of use:
from logging import INFO, basicConfig

from tecoroute_proxy import ProxyServer

basicConfig(level=INFO)
