熊猫read_html给我的权限被拒绝（403）

Question

I signed up to get currency price via a provider. When I use pd.read_html('URL') I get 403 error - permission denied. So I then tried to emulate a browser by doing this-

import pandas as pd
import matplotlib.pyplot as plt
import html5lib
import requests
%matplotlib inline

### Pretend to be a browser ###
url = 'URL_TO_PROVIDER_WITH_TOKEN'
header = {"User-Agent": "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.75 Safari/537.36","X-Requested-With": "XMLHttpRequest"}

r = requests.get(url, headers=header)

currency = pd.read_html('r')

However this gives me "no tables found". The source looks like this -

{"status":true,"currency":[{"currency":"GBP\/CAD","value":"1.7136","date":"2019-01-18 17:19:58","type":"original"}]}

What do I do wrong?

EDIT

If there are no tables in source file, how then can I get data into Pandas? As you can see the data I would like to "parse" looks like this (json)

{"status":true,"currency":[{"currency":"GBP\/CAD","value":"1.7136","date":"2019-01-18 17:19:58","type":"original"}]}

EDIT

Ok obvious the source was not html and had no tables in it. Therefor JSON was the way to go. I managed to save the JSON structure with

r = requests.get(url, headers=header).json()

But then I am stuck. Output of r looks like this -

{'status': True,
 'currency': [{'currency': 'GBP/CAD',
   'value': '1.7083',
   'date': '2019-01-18 22:59:58',
   'type': 'original'}]}

How do I get columns to dataframe? I want 'currency': 'GBP/CAD', 'value': '1.7083' and 'date': '2019-01-18 22:59:58'

EDIT - SOLUTION

url = 'URL_API_TOKEN'
header = {"User-Agent": "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/50.0.2661.75 Safari/537.36","X-Requested-With": "XMLHttpRequest"}

r = requests.get(url, headers=header).json()

data = json_normalize(r['currency'])

Answer 1

Try to use : currency = pd.read_html(r)

instead of : currency = pd.read_html('r')

because you call the method read_html with the string "r" as argument and not the variable r
