Wishlist Scrape

This project aims to generate simple log files containing current prices on items from your wishlist (and their sum).

Dependencies

This project makes use of the following python3 libs:

• urllib
• re
• json
• datetime
• threadings
• sys
• os
• bs4

Execution

Just follow the steps:

1. make
2. ./wcalc -l path/to/file/with/links -o output/file/directory

usage: wcalc.py [-h] -l list.txt [-o output_file.txt] [-T]

optional arguments:
  -h, --help            show this help message and exit
  -l list.txt           List of products (one link per line)
  -o output_file.json   Output fetched prices
  -T, --no-threading    Disable parallel fetches

Use examples

Let's say that i have a file on lists/test.txt with this inside:

https://produto.mercadolivre.com.br/MLB-1146730903-amd-ryzen-2700x-am4-43ghz-octa-core-16theads-rgb-lacrado-_JM
https://produto.mercadolivre.com.br/MLB-1024669523-adaptador-ativo-displayport-p-hdmi-20-4k-60hz-club3d-uhd-_JM
https://produto.mercadolivre.com.br/MLB-960954066-memoria-kingston-hyperx-fury-8gb-2400mhz-ddr4-gamer-cl15-_JM

I could run the program by typing the following commands:

./wcalc lists/test.txt logs

And then, the program will automatically see the domain on the links and select the right API for that site.

Supported Websites

At the moment, the API only extends to the following websites:

• mercadolivre
• kabum
• terabyteshop
• amazon (Outdated)

Creating your custom API

I've designed this script to be as modular as you want. So with that in mind, just need some little coding to make this script adapt to your desired website.

You'll need basic knowledge in re and python3 in order to create your own API.

With that in mind, follow these steps:

• Navigate to src/sites and create your own website API (ex: google.py)

• On the source file, follow the guide below:

  class Google:
      def fetch(self, link):
          # Here you fetch on the link given the information you want
          # then, after fetched, return a dictionary with the following
          # keys:
          # dict['title'] -> product title, need to be a String
          # dict['price'] -> product price, need to be a Float

• Then, go to src/sites/api.py and include on the header an import to your API, like this:

  from sites.google import Google
  #          ^your file    ^your class

• And then, add support to your API down there:

  # Possible domains and it's correspondent API's
      domains = {
          'kabum.com.br': Kabum,
          'terabyteshop.com.br': Terabyte,
          'mercadolivre.com.br': ML,
          'google.com.br': Google,            # ADD THIS LINE
  }

• Test your API and feel free to make a Pull Request!
