Python Rest API by Bill Bitner

Hi!

Thank you for providing a wonder environment to investigate the wonderful world of market data.

I run on Linux and would like to use the REST external API so I can edit in emacs, and such. My first test has been unsuccessful and I'm betting someone else spot the problem. I looked at jorgemanbia ruby implemention and tried to do the same thing.. It didn't work.. lol

import reqests, hashlib, time

authTok = "string from my accounts page"

user = 12345 # number from by accounts page

hasher = hashlib.sha256()
hasher.update(authTok)

ts = int(time.time())

authStr = hasher.hexdigest()

payload = {"Timestamp" : ts}

resp = requests.get("https://www.quantconnect.com/api/v2/projects/read", auth = (user, authTok), params = payload)

print resp.status_code
print resp.text

#################

when run, the printing the resp.text gives the following string

{"errors":["Hash doesn't match. UID: 123455 Hash: the string from hexdigest Timestamp: ''"],"success":false}

Any clues, pointers, help?

Thanks, Bill Bitner

Bill Bitner, we have a C# API that can be used with pythonnet to create a Python REST API.

Thanks Alexandre Catarino for your time and reply. By looking at the C# API, I was able to spot the errors in my code. Here is the code snippet to read projects list via the rest API

#!/usr/bin/env python



import hashlib

import time

import requests

from requests_toolbelt.utils import dump



authTok = "The hex digit string from the accounts page"

user = 12345 # my userId from the accounts page



hasher = hashlib.sha256()

ts = int(time.time())

authStr = "%s:%d"%(authTok, ts)  # this is in the API

hasher.update(authStr)

authHexDigest = hasher.hexdigest()

print authHexDigest

head = {"Content-type": "application/json", "Timestamp" : "%d"%(ts)} # Timestamp must be in the header too!

resp = requests.get("https://www.quantconnect.com/api/v2/projects/read", auth = (user, authHexDigest), headers = head, params = {})



data = dump.dump_all(resp)

print(data.decode('utf-8'))

Thanks again!!
