This project may lack some general elegance which you could expect. Also, there are some missing features, like validating that input isn't empty and so on. I decided not to overcomplicate such a trivial task and stick to the most straightforward solution which came to my mind. No tests included because of the time pressure I'm currently in. During development Cabal was used as a build tool, so I recommend you to use it as well. To run the server just clone this repository and fire cabal new-run command in the project's root directory.
GET /covid19.html
If no query arguments provided, returns a following template:
<html>
<head><title>Shabak COVID-19 Registration</title></head>
<body><h1>Shabak COVID-19 Registration</h1>
<form>
<div>
<label for="name">Name: </label>
<input type="text" name="name" id="name">
</div>
<div>
<label for="tel">Tel: </label>
<input type="text" name="tel" id="tel">
</div>
<div>
<input type="checkbox" name="covid19" id="covid19">
<label for="covid19"> Tested positive for COVID-19</label>
</div>
<div>
<input type="submit">
</div>
</form>
</body>
</html>Otherwise, expects name, tel, and (optionally) covid19 arguments. name and tel can be any textual data, covid19 can only have on value. Presence of the last argument indicates positive result from Covid test, absence, respectively, indicates negative one. For example,
GET /covid19.html?name=Magnus&tel=527591745
would return following result:
<!DOCTYPE HTML>
<html>
<head>
