screenshot-service

A Python based scalable back-end service using RabbitMQ's pika library.

How to:

• Start the reader component:
  python reader.py

• Start a couple of independent receiver components by assigning them an id:
  python receiver.py 1 , python receiver.py 2 etc.

• Start the sender component:
  python sender.py
  or
  python sender.py <urls>
  with <urls> being a file with urls, one per line.

• receiver.py receives the requests for downloading the screenshots and downloads them.

• Request a screenshot by querying it to sender.py as get <url> (<url> should be exactly the same as requested previously, or as in the <urls> file, otherwise it will not be found in the existing screenshots, and a new request for downloading will be issued.

Requirements:

• Linux
• RabbitMQ
• RabbitMQ (pika) for python
• gnome-web-photo should be already built-in in Linux.
