I just wanted to ask what can I do to solve this issue I have.

Essentially I am making a stock checker for sneakers from Adidas, I know the endpoint to obtain the stock but the JSON data given back to me whilst readable and contains what I need also contains a bunch of other information that is unnecessary to what I am trying to do.

Example of a link to an endpoint:

http://production.store.adidasgroup.demandware.net/s/adidas-GB/dw/shop/v16_9/products/(BZ0221)?client_id=c1f3632f-6d3a-43f4-9987-9de920731dcb&expand=availability,variations,prices

This is a link to the JSON containing the stock of the shoe, price and availability. However, if you try to open it you'll see that it responds a bunch of useless info such as the description of the shoe and the price which I do not need.

A github repository that I was using to try and get to grips with the requests I am trying to make is:

https://github.com/yzyio/adidas-stock-checker/blob/master/assets/index.js

I can get it to give me the JSON response I am just trying to strip what I don't need and keep what I do need which I am finding very difficult especially in python.

Many Thanks!

  • just choose what fields of the json file are useful for you... – coder Aug 18 '17 at 14:22

Since you've said you can get a JSON response from the server than the first think you need to do is tell python to load it as JSON. 

import json
data = json.loads(response_from_server)

After doing this you can now access the values in your JSON object the way you would access them via a Python dict.

data["artist"]["id"]

  • Hi, I tried doing thsi with the objects "name" and "variants" as a test but I end up getting this `TypeError: the JSON object must be str, bytes or bytearray, not 'Response'` – Fader910 Aug 18 '17 at 14:33
  • That means response_from_server is not a string, try evaluating what type of object this is.... if it's a response object than you may need to say data = json.loads(response_from_server.text) – Chris Hawkes Aug 18 '17 at 14:37

    It's best to use `.content`, `.text` will try to decode the response. Or even better use `.json()` which returns a json object. – t.m.adam Aug 18 '17 at 14:42
