So, I'm using python request to POST data to an API, this API allows me to check more users at the same time by using the same data param,
example: if I want to check j#mail.com & x#gmail.com, if I used GET, (but I wanna use POST because I wanna check a lot of mails with one request) I'd have to query this url: htttps://website.com/API?email=j#mail.com&email=x#mail.com.
How do I change my dict (v) in order to make this possible?
This is the code I've written:
def query(rurl, data):
r = requests.post(rurl, data = data).json()
print (r)
def main():
v = {
'apikey': apikey,
'email': username,
'password': password,
}
query('https://website.com/API', v)
if __name__ == "__main__":
main()
If you give a list object as your value in v for a certain key, it produces multiple parameters of the same name. For example:
v = { ...
"email": ["j#mail.com", "x#mail.com"],
... }
This should work with either GET or POST requests.
To incorporate this into your existing code:
def query(rurl, data):
r = requests.post(rurl, data = data).json()
print (r)
def main():
v = {
'apikey': apikey,
'email': [username1, username2],
'password': password,
}
query('https://website.com/API', v)
if __name__ == "__main__":
main()
According to Documentation
def query(rurl, data):
r = requests.post(rurl, params = data)
print (r)
v = { ...
"email": ["j#mail.com", "x#mail.com"],
... }

This is my code to extract player data from an endpoint containing basketball data for a Data Science project.NOTE: I changed the name of the actual API key I was given since it's subscription. And I change the username/password because for privacy purposes. Using the correct credentials, I wouldn't receive a syntax error but the status code always returns 401. Since it wasn't accepting the API key, I added my account username, password, and the HTTP authentication header as well, but the status code still returns 401.
In case this is relevant, this is the website's recommendation in the developer portal: **The API key can be passed either as a query parameter or using the following HTTP request header.
Please let me know what changes I can make to my code. Any help is appreciated.
Ocp-Apim-Subscription-Key: {key}**
PS: My code got fragmented while posting this, but it is all in one function.
def getData():
user_name = "name#gmail.com"
api_endpoint = "https://api.sportsdata.io/v3/nba/stats/json/PlayerGameStatsByDate/2020-FEB7"
api_key = "a45;lkf"
password = "ksaljd"
header = "Ocp-Apim-Subscription-Key"
PARAMS = {'user': user_name, 'pass': password, 'header': header, 'key': api_key}
response = requests.get(url = api_endpoint, data = PARAMS)
print(response.status_code)
file = open("Data.csv", "w")
file.write(response.text)
file.close()
def _get_auth_headers() -> dict:
return {
'Content-Type': 'application/json',
'Ocp-Apim-Subscription-Key': "`Insert key here`"
}
api_endpoint = "https://api.sportsdata.io/v3/nba/stats/json/PlayerGameStatsByDate/2020-FEB7"
PARAMS = {
# Your params here
}
response = requests.get(
api_endpoint,
headers=_get_auth_headers(),
params=PARAMS
)
Instead of just a string, you need to pass dict in the headers parameter and auth param exist so you can use it as follow:
def getData():
[...]
header = {
"Ocp-Apim-Subscription-Key": api_key
}
[...]
response = requests.get(url = api_endpoint, data = PARAMS, headers=header, auth = (user_name, password))
According to the API documentation you don't need to provide email and password. You're only need to add your API Key to header:
import requests
r = requests.get(url='https://api.sportsdata.io/v3/nba/stats/json/PlayerGameStatsByDate/2020-FEB7', headers={'Ocp-Apim-Subscription-Key': 'API_KEY'})
print(r.json())
Output:

I have a python script as below that gather some stores' informations using google API :
import json
import requests
import time
from config import API_KEY, PLACES_ENDPOINT
def getPlaces(lat, lng, radius, keyword, token=None, places=None):
# Building my API call
params = {
'location': str(lat) + ',' + str(lng),
'radius': radius,
'keyword': keyword,
'key': API_KEY
}
if token is not None:
params.update({'pagetoken': token})
r = requests.get(PLACES_ENDPOINT, params=params)
# If its the first time the function is called, then we create the list variable
if places is None:
places = []
for item in r.json()['results']:
# adding element to my list 'places'
places.append(item['name'])
# if there is more results to gather from the next page, call the func again
if 'next_page_token' in r.json():
token = r.json()['next_page_token']
time.sleep(2)
getPlaces(lat, lng, radius, keyword, token, places)
else:
print(json.dumps(places)) # print all the data collected
return json.dumps(places) # return None
Why the returned json places is None whereas the data appears as it should be in the final print ?
To fix my issues I just had to get rid of the else statement.
As the function is recursive, it won't proceed to the return until it ends looping :
import json
import requests
import time
from config import API_KEY, PLACES_ENDPOINT
def getPlaces(lat, lng, radius, keyword, token=None, places=None):
params = {
'location': str(lat) + ',' + str(lng),
'radius': radius,
'keyword': keyword,
'key': API_KEY
}
if token is not None:
params.update({'pagetoken': token})
r = requests.get(PLACES_ENDPOINT, params=params)
# parsing json
if places is None:
places = []
for item in r.json()['results']:
places.append(item['name'])
if 'next_page_token' in r.json():
token = r.json()['next_page_token']
time.sleep(2)
getPlaces(lat, lng, radius, keyword, token, places)
return json.dumps(places)
Thanks Michael Butscher for the hint !
I am trying to get a python script to say whether a twitch channel is live but haven't been able to do it, any and all help would be appreciated.
here are the docs I've been able to find
https://dev.twitch.tv/docs/api/guide
This is what I have atm but I keep on getting "'set' object has no attribute 'items'". This is modified code from "Is There Any Way To Check if a Twitch Stream Is Live Using Python?" however it is now outdated because of the new API.
import requests
def checkUser():
API_HEADERS = {
'Client-ID : [client id here from dev portal]',
'Accept : application/vnd.twitchtv.v5+json',
}
url = "https://api.twitch.tv/helix/streams/[streamer here]"
req = requests.Session().get(url, headers=API_HEADERS)
jsondata = req.json()
print(jsondata)
checkUser()
The answer to your problem of "'set' object has no attribute 'items'" is just a simple typo. It should be
API_HEADERS = {
'Client-ID' : '[client id here from dev portal]',
'Accept' : 'application/vnd.twitchtv.v5+json'
}
Notice how the Colon's aren't part of the text now
And to answer your overarching question of how to tell if a channel is online you can look at this sample code I made.
import requests
URL = 'https://api.twitch.tv/helix/streams?user_login=[Channel_Name_Here]'
authURL = 'https://id.twitch.tv/oauth2/token'
Client_ID = [Your_client_ID]
Secret = [Your Client_Secret]
AutParams = {'client_id': Client_ID,
'client_secret': Secret,
'grant_type': 'client_credentials'
}
def Check():
AutCall = requests.post(url=authURL, params=AutParams)
access_token = AutCall.json()['access_token']
head = {
'Client-ID' : Client_ID,
'Authorization' : "Bearer " + access_token
}
r = requests.get(URL, headers = head).json()['data']
if r:
r = r[0]
if r['type'] == 'live':
return True
else:
return False
else:
return False
print(Check())
I have been struggling to send a signed request to binance future using signature.
I found that example code on StackOverflow ("Binance API call with SHA56 and Python requests") and an answer has been given to it mentioning to use hmac
as below: but unfortunately i still don't see how to write this example. Could anyone show how the code of this example should look like? i am really uncomfortable with signed request. Thanks a lot for your understanding and your help advice given:
params = urlencode({
"signature" : hashedsig,
"timestamp" : servertimeint,
})
hashedsig = hmac.new(secret.encode('utf-8'), params.encode('utf-8'), hashlib.sha256).hexdigest()
Original example:
import requests, json, time, hashlib
apikey = "myactualapikey"
secret = "myrealsecret"
test = requests.get("https://api.binance.com/api/v1/ping")
servertime = requests.get("https://api.binance.com/api/v1/time")
servertimeobject = json.loads(servertime.text)
servertimeint = servertimeobject['serverTime']
hashedsig = hashlib.sha256(secret)
userdata = requests.get("https://api.binance.com/api/v3/account",
params = {
"signature" : hashedsig,
"timestamp" : servertimeint,
},
headers = {
"X-MBX-APIKEY" : apikey,
}
)
print(userdata)
The proper way would be:
apikey = "myKey"
secret = "mySecret"
servertime = requests.get("https://api.binance.com/api/v1/time")
servertimeobject = json.loads(servertime.text)
servertimeint = servertimeobject['serverTime']
params = urlencode({
"timestamp" : servertimeint,
})
hashedsig = hmac.new(secret.encode('utf-8'), params.encode('utf-8'),
hashlib.sha256).hexdigest()
userdata = requests.get("https://api.binance.com/api/v3/account",
params = {
"timestamp" : servertimeint,
"signature" : hashedsig,
},
headers = {
"X-MBX-APIKEY" : apikey,
}
)
print(userdata)
print(userdata.text)
Make sure to put the signature as the last parameter or the request will return [400]...
Incorrect:
params = {
"signature" : hashedsig,
"timestamp" : servertimeint,
}
Correct:
params = {
"timestamp" : servertimeint,
"signature" : hashedsig,
}
At the time of writing, Binance themselves are mainting a repo with some examples*, using the requests library. Here is a sample in case the link goes down or is moved:
import hmac
import time
import hashlib
import requests
from urllib.parse import urlencode
KEY = ''
SECRET = ''
# BASE_URL = 'https://fapi.binance.com' # production base url
BASE_URL = 'https://testnet.binancefuture.com' # testnet base url
''' ====== begin of functions, you don't need to touch ====== '''
def hashing(query_string):
return hmac.new(SECRET.encode('utf-8'), query_string.encode('utf-8'), hashlib.sha256).hexdigest()
def get_timestamp():
return int(time.time() * 1000)
def dispatch_request(http_method):
session = requests.Session()
session.headers.update({
'Content-Type': 'application/json;charset=utf-8',
'X-MBX-APIKEY': KEY
})
return {
'GET': session.get,
'DELETE': session.delete,
'PUT': session.put,
'POST': session.post,
}.get(http_method, 'GET')
# used for sending request requires the signature
def send_signed_request(http_method, url_path, payload={}):
query_string = urlencode(payload)
# replace single quote to double quote
query_string = query_string.replace('%27', '%22')
if query_string:
query_string = "{}×tamp={}".format(query_string, get_timestamp())
else:
query_string = 'timestamp={}'.format(get_timestamp())
url = BASE_URL + url_path + '?' + query_string + '&signature=' + hashing(query_string)
print("{} {}".format(http_method, url))
params = {'url': url, 'params': {}}
response = dispatch_request(http_method)(**params)
return response.json()
# used for sending public data request
def send_public_request(url_path, payload={}):
query_string = urlencode(payload, True)
url = BASE_URL + url_path
if query_string:
url = url + '?' + query_string
print("{}".format(url))
response = dispatch_request('GET')(url=url)
return response.json()
response = send_signed_request('POST', '/fapi/v1/order', params)
print(response)
Some additional thoughts from myself:
You can also use a new library also from Binance called Binance connector. It is a bit new, it has some issues, but it can do the basic operations without you worrying about signed requests.
I wouldn't use serverTime because that means you need to make an additional request and networks can be slow, I'd follow this example and use the int(time.time() * 1000) you may not even need the function.
I purposedly used the POST example, because this is more complicated as you need to also encode and hash your custom parameters
At the time of writing, v3 is the latest version
Hope it helps.

What is the proper way to handle response classes in Flask-RESTplus?
I am experimenting with a simple GET request seen below:
i_throughput = api.model('Throughput', {
'date': fields.String,
'value': fields.String
})
i_server = api.model('Server', {
'sessionId': fields.String,
'throughput': fields.Nested(i_throughput)
})
#api.route('/servers')
class Server(Resource):
#api.marshal_with(i_server)
def get(self):
servers = mongo.db.servers.find()
data = []
for x in servers:
data.append(x)
return data
I want to return my data in as part of a response object that looks like this:
{
status: // some boolean value
message: // some custom response message
error: // if there is an error store it here
trace: // if there is some stack trace dump throw it in here
data: // what was retrieved from DB
}
I am new to Python in general and new to Flask/Flask-RESTplus. There is a lot of tutorials out there and information. One of my biggest problems is that I'm not sure what to exactly search for to get the information I need. Also how does this work with marshalling? If anyone can post good documentation or examples of excellent API's, it would be greatly appreciated.
