print(k.get_access_token())
The code is originally not mine so I don't know exactly how it works. When I run this it says I need to add positional argument 'self'
You need to initialize the ExampleOAuth2Client object properly.
Instead of this:
k = ExampleOAuth2Client
It should look something like:
k = ExampleOAuth2Client('your-client-id', 'your-client-secret')
I'd like to get the balance of a TRC20 token (in this case the WIN token) for a Tron wallet address that owns WIN tokens.
I'm using the Python module tron-api-python and based on what i've read on GitHub and the docs the code for that should look something like this:
from tronapi import Tron

tron = Tron()

But the result i get is:

You can use this API:
import requests
import json
def get_balance(address, token_symbol):
url = "https://apilist.tronscan.org/api/account"
payload = {
"address": address,
}
res = requests.get(url, params=payload)
trc20token_balances = json.loads(res.text)["trc20token_balances"]
token_balance = next((item for item in trc20token_balances if item["symbol"] == token_symbol), None)
if token_balance == None:
return 0
else:
return int(token_balance["balance"])
The previous response broadcasts a transaction to read a constant function; you don't need to do that if you're only going to read the balance.
Found it myself. This is not the code to get the balance but to send the WIN token so for this to return the balance the function_selector and the parameters would need to change but the rest should be fine since both is based on triggering a smart contract.

raw_tx = tron.transaction_builder.trigger_smart_contract(**kwargs)
sign = tron.trx.sign(raw_tx["transaction"])
result = tron.trx.broadcast(sign)
I am trying to get the list of all calendars for a user. This user has delegate permissions to view the calendar of all the meeting rooms (resources). If I log into the user's account and I am able to see the meeting room calendars in the "Other Calendars" section. I also created my own calendar called "Test" in the "Other Calendars" section.
When I get all the calendar groups first and then iterate through the calendar group list and get the calendars, the list for "Other Calendars" only has "Test" calendar.
Not sure why this is the case. The user is a global administrator as well.

Step 1) Get the authorization URL:
authority = "https://login.microsoftonline.com/common"
authorize_url = '{0}{1}'.format(authority, '/oauth2/authorize?client_id={0}&redirect_uri={1}&response_type=code&state={2}&prompt=consent')
Step 2) Opening the URL takes us to https://login.microsoftonline.com/common where I login as the user:
Step 3) This redirects back to my localhost then the following:
discovery_result = exchoauth.get_access_info_from_authcode(auth_code, Office365.redirect_uri)
refresh_token = discovery_result['refresh_token']
client_id = client_registration.client_id()
client_secret = client_registration.client_secret()

cal_groups = {}
if calendar_groups_json is not None:
for entry in calendar_groups_json['value']:
cal_group_id = entry['Id']
cal_group_name = entry['Name']
cal_groups[cal_group_id] = cal_group_name
calendars_json_list = exchoauth.get_calendars_from_calendar_groups(Office365.api_endpoint,
access_token, cal_groups)
for calendars_json in calendars_json_list:
if calendars_json is not None:
for ent in calendars_json['value']:
cal_id = ent['Id']
cal_name = ent['Name']
calendar_ids[cal_id] = cal_name
Let me know if you need any other information
The delegate-token which request with the Auth code grant flow only able to get the calendars of sign-in user.
If you want to the get the events from the specific room, you can use the app-only token request with client credential flow.
Here is an helpful link for your reference.
I'm just wondering if there is any way to write a python script to check to see if a twitch.tv stream is live?
I'm not sure why my app engine tag was removed, but this would be using app engine.
Since all answers are actually outdated as of 2020-05-02, i'll give it a shot. You now are required to register a developer application (I believe), and now you must use an endpoint that requires a user-id instead of a username (as they can change).
See https://dev.twitch.tv/docs/v5/reference/users
and https://dev.twitch.tv/docs/v5/reference/streams
First you'll need to Register an application
From that you'll need to get your Client-ID.
The one in this example is not a real
TWITCH_STREAM_API_ENDPOINT_V5 = "https://api.twitch.tv/kraken/streams/{}"
API_HEADERS = {
'Client-ID' : 'tqanfnani3tygk9a9esl8conhnaz6wj',
'Accept' : 'application/vnd.twitchtv.v5+json',
}
reqSession = requests.Session()
def checkUser(userID): #returns true if online, false if not
url = TWITCH_STREAM_API_ENDPOINT_V5.format(userID)
try:
req = reqSession.get(url, headers=API_HEADERS)
jsondata = req.json()
if 'stream' in jsondata:
if jsondata['stream'] is not None: #stream is online
return True
else:
return False
except Exception as e:
print("Error checking user: ", e)
return False
I hated having to go through the process of making an api key and all those things just to check if a channel was live, so i tried to find a workaround:
As of june 2021 if you send a http get request to a url like https://www.twitch.tv/CHANNEL_NAME, in the response there will be a "isLiveBroadcast": true if the stream is live, and if the stream is not live, there will be nothing like that.
So i wrote this code as an example in nodejs:
const fetch = require('node-fetch');
const channelName = '39daph';
async function main(){
let a = await fetch(`https://www.twitch.tv/${channelName}`);
if( (await a.text()).includes('isLiveBroadcast') )
console.log(`${channelName} is live`);
else
console.log(`${channelName} is not live`);
}
main();
here is also an example in python:
import requests
channelName = '39daph'
contents = requests.get('https://www.twitch.tv/' +channelName).content.decode('utf-8')
if 'isLiveBroadcast' in contents:
print(channelName + ' is live')
else:
print(channelName + ' is not live')
It looks like Twitch provides an API (documentation here) that provides a way to get that info. A very simple example of getting the feed would be:
import urllib2
url = 'http://api.justin.tv/api/stream/list.json?channel=FollowGrubby'
contents = urllib2.urlopen(url)
print contents.read()
This will dump all of the info, which you can then parse with a JSON library (XML looks to be available too). Looks like the value returns empty if the stream isn't live (haven't tested this much at all, nor have I read anything :) ). Hope this helps!
RocketDonkey's fine answer seems to be outdated by now, so I'm posting an updated answer for people like me who stumble across this SO-question with google.
You can check the status of the user EXAMPLEUSER by parsing
https://api.twitch.tv/kraken/streams/EXAMPLEUSER
The entry "stream":null will tell you that the user if offline, if that user exists.
Here is a small Python script which you can use on the commandline that will print 0 for user online, 1 for user offline and 2 for user not found.
#!/usr/bin/env python3
# checks whether a twitch.tv userstream is live
import argparse
from urllib.request import urlopen
from urllib.error import URLError
import json
def parse_args():
""" parses commandline, returns args namespace object """
desc = ('Check online status of twitch.tv user.\n'
'Exit prints are 0: online, 1: offline, 2: not found, 3: error.')
parser = argparse.ArgumentParser(description = desc,
formatter_class = argparse.RawTextHelpFormatter)
parser.add_argument('USER', nargs = 1, help = 'twitch.tv username')
args = parser.parse_args()
return args
def check_user(user):
""" returns 0: online, 1: offline, 2: not found, 3: error """
url = 'https://api.twitch.tv/kraken/streams/' + user
try:
info = json.loads(urlopen(url, timeout = 15).read().decode('utf-8'))
if info['stream'] == None:
status = 1
else:
status = 0
except URLError as e:
if e.reason == 'Not Found' or e.reason == 'Unprocessable Entity':
status = 2
else:
status = 3
return status
# main
try:
user = parse_args().USER[0]
print(check_user(user))
except KeyboardInterrupt:
pass
Here is a more up to date answer using the latest version of the Twitch API (helix). (kraken is deprecated and you shouldn't use GQL since it's not documented for third party use).
It works but you should store the token and reuse the token rather than generate a new token every time you run the script.
import requests
client_id = ''
client_secret = ''
streamer_name = ''
body = {
'client_id': client_id,
'client_secret': client_secret,
"grant_type": 'client_credentials'
}
r = requests.post('https://id.twitch.tv/oauth2/token', body)
#data output
keys = r.json();
print(keys)
headers = {
'Client-ID': client_id,
'Authorization': 'Bearer ' + keys['access_token']
}
print(headers)
stream = requests.get('https://api.twitch.tv/helix/streams?user_login=' + streamer_name, headers=headers)
stream_data = stream.json();
print(stream_data);
if len(stream_data['data']) == 1:
print(streamer_name + ' is live: ' + stream_data['data'][0]['title'] + ' playing ' + stream_data['data'][0]['game_name']);
else:
print(streamer_name + ' is not live');
📚 Explanation
Now, the Twitch API v5 is deprecated. The helix API is in place, where an OAuth Authorization Bearer AND client-id is needed. This is pretty annoying, so I went on a search for a viable workaround, and found one.
🌎 GraphQL
When inspecting Twitch's network requests, while not being logged in, I found out the anonymous API relies on GraphQL. GraphQL is a query language for APIs.
query {
user(login: "USERNAME") {
stream {
id
}
}
}
In the graphql query above, we are querying a user by their login name. If they are streaming, the stream's id will be given. If not, None will be returned.
🐍 The Final Code
The finished python code, in a function, is below. The client-id is taken from Twitch's website. Twitch uses the client-id to fetch information for anonymous users. It will always work, without the need of getting your own client-id.
import requests
# ...
def checkIfUserIsStreaming(username):
url = "https://gql.twitch.tv/gql"
query = "query {\n user(login: \""+username+"\") {\n stream {\n id\n }\n }\n}"
return True if requests.request("POST", url, json={"query": query, "variables": {}}, headers={"client-id": "kimne78kx3ncx6brgo4mv6wki5h1ko"}).json()["data"]["user"]["stream"] else False
I've created a website where you can play with Twitch's GraphQL API. Refer to the GraphQL Docs for help on GraphQL syntax! There's also Twitch GraphQL API documentation on my playground.
Use the twitch api with your client_id as a parameter, then parse the json:
https://api.twitch.tv/kraken/streams/massansc?client_id=XXXXXXX
Twitch Client Id is explained here: https://dev.twitch.tv/docs#client-id,
you need to register a developer application: https://www.twitch.tv/kraken/oauth2/clients/new
Example:
import requests
import json
def is_live_stream(streamer_name, client_id):
twitch_api_stream_url = "https://api.twitch.tv/kraken/streams/" \
+ streamer_name + "?client_id=" + client_id
streamer_html = requests.get(twitch_api_stream_url)
streamer = json.loads(streamer_html.content)
return streamer["stream"] is not None
I'll try to shoot my shot, just in case someone still needs an answer to this, so here it goes
import requests

from twitchAPI.twitch import Twitch
client_id = ""
client_secret = ""
twitch = Twitch(client_id, client_secret)

}
def checkUser(user): #returns true if online, false if not
userid = twitch.get_users(logins=[user])['data'][0]['id']
url = TWITCH_STREAM_API_ENDPOINT_V5.format(userid)
try:
req = requests.Session().get(url, headers=API_HEADERS)

if 'stream' in jsondata:

return True
else:

You can use Twitch API call https://api.twitch.tv/kraken/streams/YOUR_CHANNEL_NAME and parse result to check if it's live.
The below function returns a streamID if the channel is live, else returns -1.
import urllib2, json, sys
TwitchChannel = 'A_Channel_Name'
def IsTwitchLive(): # return the stream Id is streaming else returns -1
url = str('https://api.twitch.tv/kraken/streams/'+TwitchChannel)
streamID = -1
respose = urllib2.urlopen(url)
html = respose.read()
data = json.loads(html)
try:
streamID = data['stream']['_id']
except:
streamID = -1
return int(streamID)
I am trying to use the instapaper API, but I keep getting a 403 error for my requests. Here's the code:
consumer_key='...'
consumer_secret='...'
access_token_url = 'https://www.instapaper.com/api/1/oauth/access_token'
consumer = oauth.Consumer(consumer_key, consumer_secret)
client = oauth.Client(consumer)
client.add_credentials('...','...')
params = {}
params["x_auth_username"] = '..'
params["x_auth_password"] = '...'
params["x_auth_mode"] = 'client_auth'
client.set_signature_method = oauth.SignatureMethod_HMAC_SHA1()
resp, token = client.request(access_token_url, method="POST",body=urllib.urlencode(params))
result = simplejson.load(urllib.urlopen('https://www.instapaper.com/api/1/bookmarks/list?' + token))
Any ideas?
You're right about the signature method.
But my main problem was that I wasn't handling the token appropriately. Here's the working code:
consumer = oauth.Consumer('key', 'secret')
client = oauth.Client(consumer)
# Get access token
resp, content = client.request('https://www.instapaper.com/api/1/oauth/access_token', "POST", urllib.urlencode({
'x_auth_mode': 'client_auth',
'x_auth_username': 'uname',
'x_auth_password': 'pass'
}))
token = dict(urlparse.parse_qsl(content))
token = oauth.Token(token['oauth_token'], token['oauth_token_secret'])
http = oauth.Client(consumer, token)
# Get starred items
response, data = http.request('https://www.instapaper.com/api/1/bookmarks/list', method='POST', body=urllib.urlencode({
'folder_id': 'starred',
'limit': '100'
}))
res = simplejson.loads(data)
First, make sure oauth2 is the library you're using. It's the most well-maintained python oauth module.
Second, this looks suspect:
client.set_signature_method = oauth.SignatureMethod_HMAC_SHA1()
You're replacing the set_signature_method function. It should be:
client.set_signature_method(oauth.SignatureMethod_HMAC_SHA1())
You should follow the example here: https://github.com/simplegeo/python-oauth2/blob/master/example/client.py
