REST API based on aiohttp and MongoDB for check images sizes.

If it need (By default conf file have settings for docker) - setup MongoDB and max urls count per request in config/conf.yaml.
Then run docker-compose build

1. with pipenv:
   pipenv shell
pipenv install
2. with virtualenv:
   python3 -m venv myenv
source myenv/bin/activate
pip3 install -r requirements.txt
   Create dir for images! mkdir src/images

If you use pipenv: pipenv install --dev

Run ./run_tests

docker-compose up

If it need - setup MongoDB and max urls count per request in config/conf.yaml.
Run MongoDB (locally for example setup host in conf.yaml and run mongo from docker file: docker-compose up mongo)
Run server python3 src/main.py

For get images info : POST request to http://localhost:8080/api/v1/images.
Data should be an array and have by default maximum 5 urls. Like this:

[
  {"url": "https://example.com/1.jpg"},
  {"url": "https://example.com/2.jpg"},
  {"url": "https://example.com/3.jpg"},
]

By default, if request contains >5 elements or have recurring urls - the array will be truncated to 5 elems. You can change it in config/conf.yaml.

Response example:

{"id": "5b8ce03685022d486fd0b316", "result": [
{"url": "https://example.com/1.jpg", "width": 2560, "height": 1707, "created": "2018.09.03 10:18"},
{"url": "https://example.com/2.jpg", "width": 2560, "height": 1707, "created": "2018.09.03 10:18"},
{"url": "https://example.com/3.jpg", "width": 2560, "height": 1707, "created": "2018.09.03 10:18"},
]}

In future you can GET info by id: http://localhost:8080/api/v1/images/5b8ce03685022d486fd0b316
