I have an implementation question...
#!/usr/bin/python
#This is the API for BTC price request.
# Average all the amounts, and push that to the program
import json
import urllib.request
from jsonpath_rw import parse as parse_jsonpath
class BtcAPI:
def __init__(self, url, api_id, json_key):
self.url = url
self.api_id = api_id
self.json_key = json_key
def btc_api_call(self):
hdr = { 'User-Agent' : 'Mozilla/5.0 (Windows NT 6.1; Win64; x64)' }
req = urllib.request.Request(self.url, headers=hdr)
readdata = urllib.request.urlopen(req)
json_data = readdata.read()
json_dict = json.loads(json_data)
results = parse_jsonpath(self.json_key).find(json_dict)
print(results)
class Price:
def __init__(self, api_id, url, json_key):
self.api_id = api_id
self.url = url
self.json_key = json_key
def pass_for_request(self):
get_price = BtcAPI(self.url, self.api_id, self.json_key)
get_price.btc_api_call()
def Coindesk():
coindesk = Price("coindesk","https://api.coindesk.com/v1/bpi/currentprice.json","time.updated")
coindesk.pass_for_request()
The value that gets passed for the "json_key" is "bpi.USD.rate_float"... inside this url. It gets passed to a class called "Price", which creates variables that pass to the class that the code above is contained in.
coindesk = Price("coindesk","api.coindesk.com/v1/bpi/currentprice.json", "bpi.USD.rate_float")
And here is the json I am targeting... trying to get to the rate_float key:
{
"time": {
"updated": "Feb 5, 2018 18:34:00 UTC",
"updatedISO": "2018-02-05T18:34:00+00:00",
"updateduk": "Feb 5, 2018 at 18:34 GMT"
},
"disclaimer": "This data was produced from the CoinDesk Bitcoin Price Index (USD). Non-USD currency data converted using hourly conversion rate from openexchangerates.org",
"chartName": "Bitcoin",
"bpi": {
"USD": {
"code": "USD",
"symbol": "$",
"rate": "7,004.9588",
"description": "United States Dollar",
"rate_float": 7004.9588
}
}
When I run the program, it sends me the output of the entire json file, rather than the specific key I am trying to target via jsonpath, using "bpi.USD.rate_float" I'm using jsonpath_rw.
How do I target the rate_float key effectively using jsonpath?
