Shorter is a simple URL Shortener built with Flask and SQLAlchemy named after a famous jazz musician.
Shorter has only been tested with python 3.5.2, but it should work fine on recent python3 versions.
Install the requirements from the requirements.txt file:
$ pip install -r requirements.txt
To initialize the database, run the init_db.py script in the project's root directory (the database is configured in shorter/config.py)
The sql_connection configuration value in config.py should be a valid SQLAlchemy database url: http://docs.sqlalchemy.org/en/rel_0_9/core/engines.html#database-urls
In order to start the server, just run the run_server.py script in the project's root directory:
$ ./run_server.py
* Running on http://127.0.0.1:5000/- convert a URL to a short URL of up to 23 characters
a. given only the original URL, generate a random short URL
curl -H "Authorization: Basic amltbXk6c2VjcmV0" -H "Content-Type: application/json" \
--data '{"url": "http://example.com"}' -X POST http://localhost:5000/
{
"shorturl": "http://localhost:5000/1",
"url": "http://example.com"
}b. given both the original URL and the desired short URL, create the desired short URL or give the user an error if that is not possible (ie. it was already taken)
curl -H "Authorization: Basic amltbXk6c2VjcmV0" -H "Content-Type: application/json" \
--data '{"url": "http://example.com", "shorturl": "foobar"}' \
http://localhost:5000/
{
"shorturl": "http://localhost:5000/foobar",
"url": "http://example.com"
}
curl -H "Authorization: Basic amltbXk6c2VjcmV0" -H "Content-Type: application/json" \
--data '{"url": "http://example.com", "shorturl": "foobar"}' \
http://localhost:5000/
{
"error": "Could not create new link. One with the given `shorturl` already exists"
}
