I created two abjects that need to be treated separated in the backend, and sent it to backend with:
const order = {
order_id: 1,
customer: {
name: "Jonas Illver"
age: 18
}
}
const car = {
model: 'XHL'
brand: 'Toyota'
}
const postData = {
order: order,
car: car
}
const res = await axios.post("orders/shipping/create", JSON.stringify(postData));
console.log(res);
And here I return the response: views.py
#api_view(['POST'])
#permission_classes([IsAuthenticated])
def shipping_create_order(request):
if request.method == 'POST':
return JsonResponse(request.POST)
Here's what the console.log prints:
res.data // {"order:"{"order_id": 1, "customer": {"name": "Jonas Illver", "age": 18}}, "car": **car object content**}
The problem is that if I try to access those data in my django view, I always got a 500 error
I tried accessing it via:
order = request.POST['order']
# and also
data = json.loads(request.POST)
order = data['order']
# also
order = request.POST.get('order')
None os the above approaches worked, the only one that doesn't occurs an 500 error is the last one, using the POST.get, but as soon as I add the if not order: return HttpResponse("No order") line, it always return "No order"
How can I access specific info from the request.POST? Am I doing something wrong with the axios request?
Try using request.data to get the data passed in the body. Have a look at the rest-framework docs.
Or another way to get the data is using json.loads(request.body). But using request.data is a bit shorter as it does the json.loads job for you.
and greetings.
I am currently trying to integrate a USSD service. I however am stuck with a platform-specific tutorial. the service is written in python flask, while I a developing using asp.net core API. In the tutorial there are certain requirements, I do not understand.
The overview of the connectivity is: here
Below are the explanations of the tutorial.
We have initialized a brand new Flask app. We have made sure that it’s
the main app running. Just below that, we have defined a route that
allows us to actually access our application. We have defined the
methods that we need which is the GET and POST HTTP methods. We have
defined a method/function that will be executed when we are accessing
the route. In this case, we’ve called it ussd_callback. Within the
method we receive some special parameters that we are getting from the
Africa’s Talking API:
session_id gets a unique session ID service_code gets your USSD code
phone_number gets the phone number thats currently accessing the USSD
text carries the user response as they use the USSD application
with the code
from flask import Flask, request
app = Flask(__name__)
response = ""
#app.route('/', methods=['POST', 'GET'])
def ussd_callback():
global response
session_id = request.values.get("sessionId", None)
service_code = request.values.get("serviceCode", None)
phone_number = request.values.get("phoneNumber", None)
text = request.values.get("text", "default")
under the ussd_callback function, one can return a raw string, like bellow:
if text == '':
response = "CON What would you want to check \n"
response += "1. My Account \n"
response += "2. My phone number"
and continue with
elif text == '1':
response = "CON Choose account information you want to view \n"
response += "1. Account number \n"
response += "2. Account balance"
After which, one can return response.
I have created my own solution in ASP.net core 5 API, with the following.
[HttpPost]
[Route("api/[controller]/AddNew")]
public ActionResult<string> AddNew(string venueId)
{
var answer = "";
int number = 0;
if (venueId is null)
{
answer = answer + "CON Please select venue:\n 1.Abor \n 2.Owo \n 3.Ugwueme \n 4.Oweli \n 0.Page 2 ";
return answer;
}
bool isReal = Int32.TryParse(venueId, out number);
if (isReal)
{
if (number == 0)
{
answer = answer = "CON \n 5.Umuogbo Agu \n 6.Awha Imezi \n 7.Ovoko \n 8.Opatu \n 9.Akiyi Umulokpa";
return answer;
}
else if (number > 9)
{
answer = answer + "CON Invalid input, Please select venue:\n 1.Abor \n 2.Owo \n 3.Ugwueme \n 4.Oweli \n 0.Page 2 ";
return answer;
}
}
else
{
answer = answer + "CON Invalid input, Please select venue:\n 1.Abor \n 2.Owo \n 3.Ugwueme \n 4.Oweli \n 0.Page 2 ";
return answer;
}
var data_venue = _db.Venues.Where(m => m.Id == number).FirstOrDefault();
if (data_venue is null)
{
return NotFound();
}
ApiReport data = new ApiReport()
{
DateReported = DateTime.Now,
VenueId = number,
};
var data_report = ReportMapping.ApiReport_To_DataReport(data);
data_report.DateReported = DateTime.Now;
data_report.PhoneNumber = "000";
_db.Reports.Add(data_report);
_db.SaveChanges();
return $"END \n Thank you for informing us about the new case in {data_venue.Name}. \n ";
}
The USSD initially runs fine and shows the base menu, but it will not work if it tries to respond. it is like I am still sending null values into the code. I would love to debug and see the input data myself but this service works with hosted applications.
I feel that I might have the input parameters wrong, or that I am not using proper headers.
Please fam, where have I gone wrong?
ive got an api that takes in an id
http://127.0.0.1:5000/api/v1/resources/books?id=u3qR4Ps4TbATrg97
looks like that
what im trying to do after that is add something to the end of the url, for example
http://127.0.0.1:5000/api/v1/resources/books?id=u3qR4Ps4TbATrg97uid=something
im not 100% sure if this is possible
# Create some test data for our catalog in the form of a list of dictionaries.
books = [
{'id': 'u3qR4Ps4TbATrg97',
'uid': 'what',
'title': 'A Fire Upon the Deep',
'author': 'Vernor Vinge',
'first_sentence': 'The coldsleep itself was dreamless.',
'year_published': '1992'}
]
#app.route('/api/v1/resources/books', methods=['GET'])
def api_id():
# Check if an ID was provided as part of the URL.
# If ID is provided, assign it to a variable.
# If no ID is provided, display an error in the browser.
if 'id' and 'uid' in request.args:
id = str(request.args['id'])
uid = str(request.args['uid'])
else:
return "Error: No id field provided. Please specify an id."
results = []
for book in books:
if book['id'] == id:
results.append(book)
if book['uid'] == uid:
results.append(book)
this is what i have so far, mostly copy pasted from here
thats no the whole file just the important bits i can think of
You can add two inputs inside the GET query like this
http://127.0.0.1:5000/api/v1/resources/books?id=u3qR4Ps4TbATrg97&uid=something
Just put an & in between!
Use request.args.get method to get parameters from your url. Also add & to your URL as a parameter separator.
from flask import Flask, request
app = Flask(__name__)
#app.route('/api/v1/resources/books')
def books():
id_ = request.args.get('id')
uid = request.args.get('uid')
return f'id: {id_}, uid: {uid}'
app.run()
Open http://127.0.0.1:5000/api/v1/resources/books?id=u3qR4Ps4TbATrg97&uid=something
in browser and you'll get:
id: u3qR4Ps4TbATrg97, uid: something
Multiple parameters|arguments are passed with & character. ?params1=5¶ms2=3. For your example: http://127.0.0.1:5000/api/v1/resources/books?id=u3qR4Ps4TbATrg97&uid=what. For the code, I would do:
from flask import Flask, request, jsonify, make_response
app = Flask(__name__)
# Create some test data for our catalog in the form of a list of dictionaries.
books = [
{
"id": "u3qR4Ps4TbATrg97",
"uid": "what",
"title": "A Fire Upon the Deep",
"author": "Vernor Vinge",
"first_sentence": "The coldsleep itself was dreamless.",
"year_published": "1992",
}
]
#app.route("/api/v1/resources/books", methods=["GET"])
def api_id():
# Check if an ID was provided as part of the URL.
# If ID is provided, assign it to a variable.
# If no ID is provided, display an error in the browser.
if set(["id","uid"]).intersection(set(request.args)):
id_ = str(request.args["id"])
uid = str(request.args["uid"])
else:
return make_response(
jsonify({"message": "Error: No id field provided. Please specify an id."}),
400,
)
results = []
for book in books:
if book["id"] == id_:
results.append(book)
if book["uid"] == uid:
results.append(book)
response = make_response(
jsonify({"message": results}),
200,
)
response.headers["Content-Type"] = "application/json"
return response
This would return status code 400 if no match and 200 when match
I'm working on a chat project on the platform Raspberry PI 3, Openelec OS.
Trying to write to the DB and getting unwanted anonymous keys.
Unwanted key marked with yellow. Movie2 and it's keys and values are the wanted result, but I made it manually.
I only ask how can I prevent this anonymous random key to be there and how can I replace it with other key? (string, a movie name for example)
This is my code:
url = 'https://chat-example-97c62.firebaseio.com/Movie1.json'
postdata = {
'date': str(time.asctime( time.localtime(time.time()) )),
'temp': str("Hello from Kodi")
}
req = urllib2.Request(url)
req.add_header('Content-Type','application/json')
data = json.dumps(postdata)
Thanks.
When you send a POST request to Firebase, it automatically generates a Key (Anonymous Key), if you want to use your own key you need to use a PATCH request, this is an example on Python 3:
def update_entry(user, message):
my_data = dict()
my_data["user"] = user
my_data["message"] = message
json_data = json.dumps(my_data).encode()
request = urllib.requests.Request("https://<YOUR-PROJECT-ID>.firebaseio.com/movies/<REPLACE_THIS_WITH_YOUR_DESIRED_KEY>.json", data=json_data, method="PATCH")
try:
loader = urllib.request.urlopen(request)
except urllib.error.URLError as e:
message = json.loads(e.read())
print(message["error"])
else:
print(loader.read())
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
import time
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.
