Amazon Scraper

A Hybrid Web scraper / API client. Supplements the standard Amazon API with web scraping functionality to get extra data. Specifically, product reviews.

Uses the Amazon Simple Product API <https://pypi.python.org/pypi/python-amazon-simple-product-api/>_ to provide API accessible data. API search functions are imported directly into the amazon_scraper module.

Parameters are in the same style as the Amazon Simple Product API, which in turn uses Bottlenose style parameters. Hence the non-Pythonic parameter names (ItemId).

The AmazonScraper constructor will pass 'args' and 'kwargs' to Bottlenose <https://github.com/lionheart/bottlenose>_ (via Amazon Simple Product API). Bottlenose supports AWS regions, queries per second limiting, query caching and other nice features. Please view Bottlenose' API for more information on this.

The latest version of python-amazon-simple-product-api (1.5.0 at time of writing), doesn't support these arguemnts, only Region. If you require these, please use the latest code from their repository with the following command::

pip install git+https://github.com/yoavaviram/python-amazon-simple-product-api.git#egg=python-amazon-simple-product-api

Caveat

Amazon continually try and keep scrapers from working, they do this by:

  • A/B testing (randomly receive different HTML).
  • Huge numbers of HTML layouts for the same product categories.
  • Changing HTML layouts.
  • Moving content inside iFrames.

Amazon have resorted to moving more and more content into iFrames which this scraper can't handle. I envisage a time where most data will be inaccessible without more complex logic.

I've spent a long time trying to get these scrapers working and it's a never ending battle. I don't have the time to continually keep up the pace with Amazon. If you are interested in improving Amazon Scraper, please let me know (creating an issue is fine). Any help is appreciated.

Review API
~~~~~~~~~~
View lists of reviews::

    >>> p = amzn.lookup(ItemId='B0051QVF7A')
    >>> rs = p.reviews()
    >>> rs.asin
    B0051QVF7A
    >>> # print the reviews on this first page
    >>> rs.ids
    ['R3MF0NIRI3BT1E', 'R3N2XPJT4I1XTI', 'RWG7OQ5NMGUMW', 'R1FKKJWTJC4EAP', 'RR8NWZ0IXWX7K', 'R32AU655LW6HPU', 'R33XK7OO7TO68E', 'R3NJRC6XH88RBR', 'R21JS32BNNQ82O', 'R2C9KPSEH78IF7']
    >>> rs.url
    http://www.amazon.com/product-reviews/B0051QVF7A/ref=cm_cr_pr_top_sort_recent?&sortBy=bySubmissionDateDescending
    >>> # iterate over reviews on this page only
    >>> for r in rs.brief_reviews:
    >>>     print(r.id)
    'R3MF0NIRI3BT1E'
    'R3N2XPJT4I1XTI'
    'RWG7OQ5NMGUMW'
    ...
    >>> # iterate over all brief reviews on all pages
    >>> for r in rs:
    >>>     print(r.id)
    'R3MF0NIRI3BT1E'
    'R3N2XPJT4I1XTI'
    'RWG7OQ5NMGUMW'
    ...

View detailed reviews::

    >>> rs = amzn.reviews(ItemId='B0051QVF7A')
    >>> # this will iterate over all reviews on all pages
    >>> # each review will require a download as it is on a seperate page
    >>> for r in rs.full_reviews():
    >>>     print(r.id)
    'R3MF0NIRI3BT1E'
    'R3N2XPJT4I1XTI'
    'RWG7OQ5NMGUMW'
    ...
    
Convert a brief review to a full review::

    >>> rs = amzn.reviews(ItemId='B0051QVF7A')
    >>> # this will iterate over all reviews on all pages
    >>> # each review will require a download as it is on a seperate page
    >>> for r in rs:
    >>>     print(r.id)
    >>>     fr = r.full_review()
    >>>     print(fr.id)

Quickly get a list of all reviews on a review page using the `all_reviews` property.
This uses the brief reviews provided on the review page to avoid downloading each review separately. As such, some information
may not be accessible::

    >>> p = amzn.lookup(ItemId='B0051QVF7A')
    >>> rs = p.reviews()
    >>> all_reviews_on_page = list(rs)
    >>> len(all_reviews_on_page)
    10
    >>> r = all_reviews_on_page[0]
    >>> r.title
    'Fantastic device - pick your Kindle!'
    >>> fr = r.full_review()
    >>> fr.title
    'Fantastic device - pick your Kindle!'

By ASIN/ItemId::

    >>> rs = amzn.reviews(ItemId='B0051QVF7A')
    >>> rs.asin
    B0051QVF7A
    >>> rs.ids
    ['R3MF0NIRI3BT1E', 'R3N2XPJT4I1XTI', 'RWG7OQ5NMGUMW', 'R1FKKJWTJC4EAP', 'RR8NWZ0IXWX7K', 'R32AU655LW6HPU', 'R33XK7OO7TO68E', 'R3NJRC6XH88RBR', 'R21JS32BNNQ82O', 'R2C9KPSEH78IF7']


For individual reviews use the `review` method::

    >>> review_id = 'R3MF0NIRI3BT1E'
    >>> r = amzn.review(Id=review_id)
    >>> r.id
    R3MF0NIRI3BT1E
    >>> r.asin
    B00492CIC8
    >>> r.url
    http://www.amazon.com/review/R3MF0NIRI3BT1E
    >>> r.date
    2011-09-29 18:27:14+00:00
    >>> r.author
    FreeSpirit
    >>> r.text
    Having been a little overwhelmed by the choices between all the new Kindles ... <snip>


By URL::

    >>> r = amzn.review(URL='http://www.amazon.com/review/R3MF0NIRI3BT1E')
    >>> r.id
    R3MF0NIRI3BT1E


User Reviews API
~~~~~~~~~~~~~~~~~~
This package also supports getting reviews written by a specific user.

Get reviews that a single author has created::

    >>> ur = amzn.user_reviews(Id="A2W0GY64CJSV5D")
    >>> ur.brief_reviews
    >>> ur.name
    >>> fr = list(ur.brief_reviews)[0].full_review()


Get reviews for a user, from a review object

    >>> r = amzn.review(Id="R3MF0NIRI3BT1E")
    >>> # we can get the reviews directly, or via the API with a URL or ID
    >>> ur = r.user_reviews()
    >>> ur = amzn.user_reviews(URL=r.author_reviews_url)
    >>> ur = amzn.user_reviews(Id=r.author_id)
    >>> ur.brief_reviews
    >>> ur.name


Iterate over the current page's reviews::

    >>> ur = amzn.user_reviews(Id="A2W0GY64CJSV5D")
    >>> for r in ur.brief_reviews:
    >>>     print(r.id)


Iterate over all author reviews::

    >>> ur = amzn.user_reviews(Id="A2W0GY64CJSV5D")
    >>> for r in ur:
    >>>     print(r.id)
