TecoRoute Proxy is a reverse proxy server that allows easy authentication to the TecoRoute service web interface using a simple POST request. It also saves the credentials and automatically logs the user in when the TecoRoute session expires.

For more TecoRoute tools, see TecoRoute.

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).

The user logs in with the following data:

An 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>

The user logs out with the following data:

An 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.

The server starts with:

tecoroute-proxy

On an unprivileged port (e.g. 8080), the server starts with:

tecoroute-proxy --port 8080

For all options, run tecoroute-proxy --help.

It is possible to use the package as a Python library. An example of usage:

from asyncio import ensure_future, get_event_loop
from logging import INFO, basicConfig

from tecoroute_proxy import ProxyServer

async def main():
    server = ProxyServer(port=8080)
    await server.start()

basicConfig(level=INFO)
ensure_future(main())
get_event_loop().run_forever()
