I am trying to make web request to my trading account . Python is unable to decode the web request. Web request is successful with code - 200.

Here is the code below

import requests

headers = {
    'accept-encoding': 'gzip, deflate, br',
    'accept-language': 'en-US,en;q=0.9',
    'user-agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/65.0.3325.181 Safari/537.36',
    'x-kite-version': '1.2.1',
    'accept': 'application/json, text/plain, */*',
    'referer': 'https://kite.zerodha.com/orders',
    'authority': 'kite.zerodha.com',
    'cookie': '__cfduid=db8fb54c76c53442fb672dee32ed58aeb1521962031; _ga=GA1.2.1516103745.1522000590; _gid=GA1.2.581693731.1522462921; kfsession=CfawFIZq2T6SghlCd8FZegqFjNIKCYuO; public_token=7FyfBbbxhiRRUso3425TViK2VmVszMCK; user_id=XE4670',
    'x-csrftoken': '7FyfBbbxhiRRUso3425TViK2VmVszMCK',
}

response = requests.get('https://kite.zerodha.com/api/orders', headers=headers)


x=str(response.content.decode("utf-8") )

Unable to decode this. Tried unicode- utf 8 and various codes available on the stakoverflow but its failed.

According to the response.headers (that you did not provide, but that are easily recoverable by running your code), the response is encoded using Brotli compression (Content-Encoding': 'br'). You can decompress it with brotlipy:

import brotli
brotli.decompress(response.content)
#b'{"status":"success","data":[{"placed_by":"XE4670","order_id":"180331000000385",  
#"exchange_order_id":null,"parent_order_id":null,"status":"REJECTED",
#"status_message":"ADAPTER is down","order_timestamp":"2018-03-31 07:59:42", 
#"exchange_update_timestamp":null,...}

Now, it's JSON, as promised ('Content-Type': 'application/json').

I fixed this issue by changing the request header,

headers = {
    'accept-encoding': 'gzip, deflate, br',
    ...}

to

headers = {
    'accept-encoding': 'gzip, deflate, utf-8',
    ...}
