amazon-python-scrapy-scraper

Python Scrapy spiders that scrape product data and reviews from Amazon.com.

This Scrapy project contains 3 seperate spiders:

Spider	Description
amazon_search	Scrapes all product data from the Amazon product search page for a given list of keywords.
amazon_search_product	Crawls Amazon product search pages for a given list of keywords, then scrapes each individual product page.
amazon_reviews	Scrapes all Amazon product reviews from a list of product ASINs.

The following articles go through in detail how these Amazon spiders were developed, which you can use to understand the spiders and edit them for your own use case.

ScrapeOps Proxy

This Amazon spider uses ScrapeOps Proxy as the proxy solution. ScrapeOps has a free plan that allows you to make up to 1,000 requests per month which makes it ideal for the development phase, but can be easily scaled up to millions of pages per month if needs be.

You can sign up for a free API key here.

To use the ScrapeOps Proxy you need to first install the proxy middleware:

pip install scrapeops-scrapy-proxy-sdk

Then activate the ScrapeOps Proxy by adding your API key to the SCRAPEOPS_API_KEY in the settings.py file.

SCRAPEOPS_API_KEY = 'YOUR_API_KEY'

SCRAPEOPS_PROXY_ENABLED = True

DOWNLOADER_MIDDLEWARES = {
    'scrapeops_scrapy_proxy_sdk.scrapeops_scrapy_proxy_sdk.ScrapeOpsScrapyProxySdk': 725,
}

ScrapeOps Monitoring

To monitor our scraper, this spider uses the ScrapeOps Monitor, a free monitoring tool specifically designed for web scraping.

Live demo here: ScrapeOps Demo

To use the ScrapeOps Proxy you need to first install the monitoring SDK:

pip install scrapeops-scrapy

Then activate the ScrapeOps Proxy by adding your API key to the SCRAPEOPS_API_KEY in the settings.py file.

SCRAPEOPS_API_KEY = 'YOUR_API_KEY'

# Add In The ScrapeOps Monitoring Extension
EXTENSIONS = {
'scrapeops_scrapy.extension.ScrapeOpsMonitor': 500, 
}


DOWNLOADER_MIDDLEWARES = {

    ## ScrapeOps Monitor
    'scrapeops_scrapy.middleware.retry.RetryMiddleware': 550,
    'scrapy.downloadermiddlewares.retry.RetryMiddleware': None,
    
    ## Proxy Middleware
    'scrapeops_scrapy_proxy_sdk.scrapeops_scrapy_proxy_sdk.ScrapeOpsScrapyProxySdk': 725,
}

If you are using both the ScrapeOps Proxy & Monitoring then you just need to enter the API key once.

Running The Scrapers

Make sure Scrapy and the ScrapeOps Monitor is installed:

pip install scrapy scrapeops-scrapy

To run the Amazon spiders you should first set the search query parameters you want to search by updating the keyword_list list in the spiders:

def start_requests(self):
    keyword_list = ['ipad']
    for keyword in keyword_list:
        amazon_search_url = f'https://www.amazon.com/s?k={keyword}&page=1'
        yield scrapy.Request(url=amazon_search_url, callback=self.parse_search_results, meta={'keyword': keyword, 'page': 1})

Then to run the spider, enter one of the following command:

scrapy crawl amazon_search_product

Customizing The Amazon Product Scraper

The following are instructions on how to modify the Amazon Product scraper for your particular use case.

Check out this guide to building a Amazon.com Scrapy product spider if you need any more information.

Configuring Amazon Product Search

To change the query parameters for the product search just change the keywords and locations in the keyword_list lists in the spider.

For example:

def start_requests(self):
    keyword_list = ['ipad', 'laptops']
    for keyword in keyword_list:
        amazon_search_url = f'https://www.amazon.com/s?k={keyword}&page=1'
        yield scrapy.Request(url=amazon_search_url, callback=self.parse_search_results, meta={'keyword': keyword, 'page': 1})

Extract More/Different Data

Amazon product pages contain a lot of useful data, however, in this spider is configured to only parse some of the data.

You can expand or change the data that gets extract by changing the yield statements:

def parse_product_data(self, response):
    image_data = json.loads(re.findall(r"colorImages':.*'initial':\s*(\[.+?\])},\n", response.text)[0])
    variant_data = re.findall(r'dimensionValuesDisplayData"\s*:\s* ({.+?}),\n', response.text)
    feature_bullets = [bullet.strip() for bullet in response.css("#feature-bullets li ::text").getall()]
    price = response.css('.a-price span[aria-hidden="true"] ::text').get("")
    if not price:
        price = response.css('.a-price .a-offscreen ::text').get("")
    yield {
        "name": response.css("#productTitle::text").get("").strip(),
        "price": price,
        "stars": response.css("i[data-hook=average-star-rating] ::text").get("").strip(),
        "rating_count": response.css("div[data-hook=total-review-count] ::text").get("").strip(),
        "feature_bullets": feature_bullets,
        "images": image_data,
        "variant_data": variant_data,
    }

Speeding Up The Crawl

The spiders are set to only use 1 concurrent thread in the settings.py file as the ScrapeOps Free Proxy Plan only gives you 1 concurrent thread.

However, if you upgrade to a paid ScrapeOps Proxy plan you will have more concurrent threads. Then you can increase the concurrency limit in your scraper by updating the CONCURRENT_REQUESTS value in your settings.py file.

# settings.py

CONCURRENT_REQUESTS = 10

Storing Data

The spiders are set to save the scraped data into a CSV file and store it in a data folder using Scrapy's Feed Export functionality.

custom_settings = {
        'FEEDS': { 'data/%(name)s_%(time)s.csv': { 'format': 'csv',}}
        }

If you would like to save your CSV files to a AWS S3 bucket then check out our Saving CSV/JSON Files to Amazon AWS S3 Bucket guide here

Or if you would like to save your data to another type of database then be sure to check out these guides:

• Saving Data to JSON
• Saving Data to SQLite Database
• Saving Data to MySQL Database
• Saving Data to Postgres Database

Deactivating ScrapeOps Proxy & Monitor

To deactivate the ScrapeOps Proxy & Monitor simply comment out the follow code in your settings.py file:

# settings.py

# SCRAPEOPS_API_KEY = 'YOUR_API_KEY'

# SCRAPEOPS_PROXY_ENABLED = True

# EXTENSIONS = {
# 'scrapeops_scrapy.extension.ScrapeOpsMonitor': 500, 
# }

# DOWNLOADER_MIDDLEWARES = {

#     ## ScrapeOps Monitor
#     'scrapeops_scrapy.middleware.retry.RetryMiddleware': 550,
#     'scrapy.downloadermiddlewares.retry.RetryMiddleware': None,
    
#     ## Proxy Middleware
#     'scrapeops_scrapy_proxy_sdk.scrapeops_scrapy_proxy_sdk.ScrapeOpsScrapyProxySdk': 725,
# }
