Simple Python Flask API for the Raul Hackerspace presence awareness

Raul Hacker Space is a hackerspace in Salvador, Brazil.

http://raulhc.cc

This is a project I developed to practice Python. The challenge is to provide a way of informing the public whether there is someone in the space so that visitors can pop in.

Running locally

To run locally you will need python and the Flask module (pip install flask) Once you install the requirements, simply run python app.py

Running on Docker

After installing Docker, first build the image using the following command:

docker build -t raul-status:latest .

Then run the Docker container:

docker run -p 5000:5000 raul-status

To run in daemon mode instead, add -d:

docker run -d -p 5000:5000 raul-status

Accessing the API

Current status

The current status will be accessible in JSON format at endpoint /status with information of date-time of the last event, open status (true|false) and the user:

http://localhost:5000/status

Alternatively, using curl:

curl -L -XGET 'http://localhost:5000/status'

Check-in

The /checkin endpoint will change the current status to open and update the date-time stamp. Optionally a user can be provided. If not provided, "Raul Seixas" will be assumed instead. It will return HTTP status 200 and the updated space status.

$ curl -H "Content-Type: application/json" -XPOST 'http://localhost:5000/status/checkin' -d '{"user": "Igor Garcia"}'
{
  "date-time": "2017-02-21T23:25:09.590457", 
  "open": true, 
  "user": "Igor Garcia"
}

Check-out

The /checkout endpoint will change the current status to closed and update the date-time stamp. Optionally a user can be provided. If not provided, "Raul Seixas" will be assumed instead. It will return HTTP status 200 and the updated space status.

$ curl -H "Content-Type: application/json" -XPOST 'http://localhost:5000/status/checkout' -d '{"user": "Rafael Gomex"}'
{
  "date-time": "2017-02-21T23:25:36.583668", 
  "open": false, 
  "user": "Rafael Gomex"
}

Testing with a HTML widget

There's a sample html file widget.htm that will try and load the correct image depending on the current status. You must adjust the value on the source code to match your server and port parameters.

With the server running, simply open the html file in any browser. You can then post to /checkin and /checkout and refresh the page to observe the image changing.
