This link is where you are sent to after entering in your hardware stats (hashrate, power, power cost, etc.). On the top bar (below the blue Twitter follow button) is a link to a JSON file created after the page loads with the hardware stats information entered; clicking on that JSON link redirects you to another URL (https://whattomine.com/asic.json).
My goal is to access that JSON file directly after manipulating the values in the URL string via the terminal. For example, if I would like to change hashrate from 100 to 150 in this portion of the URL:
[sha256_hr]=100& ---> [sha256_hr]=150&
After the URL manipulations (like above, but not limited to), I would like to receive the JSON output so that I can pick-out the desired data.
Advisory: I started Python programming ~June 2017, please forgive.
import json
import pandas as pd
import urllib2
import requests
hashrate_ghs = float(raw_input('Hash Rate (TH/s): '))
power_W = float(raw_input('Power of Miner (W): '))
electric_cost = float(raw_input('Cost of Power ($/kWh): '))
hashrate_ths = hashrate_ghs * 1000
initial_request = ('https://whattomine.com/asic?utf8=%E2%9C%93&sha256f=true&factor[sha256_hr]={0}&factor[sha256_p]={1}&factor[cost]={2}&sort=Profitability24&volume=0&revenue=24h&factor[exchanges][]=&factor[exchanges][]=bittrex&dataset=Main&commit=Calculate'.format(hashrate_ths, power_W, electric_cost))
data_stream_mine = urllib2.Request(initial_request)
json_data = requests.get('https://whattomine.com/asic.json')
print json_data
I am getting an HTTPS handshake error. This is where my Python freshness is second most blatantly visible:
Traceback (most recent call last):

Thank you for your help and time!

看起来其他一些人遇到了类似的问题。
虽然对于某些人来说它似乎像pyOpenSSL version issue，卸载并重新安装已经解决了问题。 SO中另一个较旧的答案是do the following。

这只是一个评论。以下方法就足够了（Python 3）。
import requests
initial_request = 'http://whattomine.com/asic.json?utf8=1&dataset=Main&commit=Calculate'
json_data = requests.get(initial_request)
print(json_data.json())
此部分的关键点 - 将.json放入initial_request，这就足够了。
