Web scraper using dynamic proxy and user agent.

Web scraper using dynamic proxy and user agent.

Description

Scraperex is simple and easy to use web scraper for retreiving data from request and avoiding HTTP 503 error (usually emerges when server is watching for bots/crawlers/requests while regular scraping).

Pakage is generating random user-agent headers using fake-useragent, and a list of proxy servers that is used while maiking requests.

Installation

pip install scraperex

Dependencies

• requests
• fake-useragent

Usage

Basic usage requires definition a dictionary with one item that contains url to the web resource, and regex which will extract the data from the response.

from scraperex import Scraper

config = {
    'my_scraping': {
        'url': 'https://www.resource.for/scraping/1',
        'regex': r'my_regular_expression'
    }
}

scraper = Scraper()
result = scraper.get(config)

Config

Config config must be of type dictionary which contains items used for scraping (as you can guess the amount of the requests will equal at least to the items amount).

Note: In case when current proxy fails next proxy server from the list will be used which will make one another request.

config = {
    'item_A': {...},
    'item_B': {...}
}

Each config item must contain two predefined properties url and regex.

    'item_A': {
        'url': 'https://www.resource.for/scraping/1',
        'regex': r'my_regular_expression'
    }

You can rescrape response content as many times as you wish by passing to regex property dictionary instead of string (also it is useful if you want to structure your results, scraping will result in the same structure you defined).

    'item_B': {
        'url': 'https://www.resource.for/scraping/2',
        'regex': {
            'structure_item': {
               'child_structure_item_1': r'my_regular_expression'
            }
            'structure_item_1':  r'my_regular_expression_1'
        }
    }
