没有使用Amazon API获得Amazon SalesRank

Question

I was using ItemLookup to get SalesRank using Amazon Product API. I am using python amazon product api

import amazonproduct
from lxml import objectify 
config = {
    'access_key': 'access key',
    'secret_key': 'secret key',
    'associate_tag': 'associate tag',
    'locale': 'us'
}
amazon = amazonproduct.API(cfg=config) 

result = amazon.item_lookup('B01B83IWH0', ResponseGroup="SalesRank")

but when i print the results their is no SalesRank, has amazon stopped giving SalesRank?

AttributeError: no such child: {http://webservices.amazon.com/AWSECommerceService/2011-08-01}SalesRank

I tried using amazon scratchpad but it also didn't give SalesRank but they have mention in their documentation to get SalesRank. How do I get SalesRank or if their is any alternative(I tried web scraping but amazon blocks me frequently). Please help, I am a beginner in using API's.

Answer 1

Using this library: https://pypi.python.org/pypi/python-amazon-simple-product-api

from amazon.api import AmazonAPI

api = AmazonAPI(ACCESS_KEY, ACCESS_KEY_SECRET, amazon_tag)

item= api.item_lookup('B01B83IWH0')

# Get Sales Rank
rank = item.sales_rank

This gets rank, but doesn't seem to reflect the current rank listed on Amazon's website. I'm only just familiarizing myself with the Amazon API, will update with elaboration and details.
