Spotify refresh token in Python 3

I am attempting to get a refresh token and use it to request a new access token when the temporary access token expires.
Spotify's documentation states the response body should contain the following json data:
{
"access_token": "NgCXRK...MzYjw",
"token_type": "Bearer",
"scope": "user-read-private user-read-email",
"expires_in": 3600,
"refresh_token": "NgAagA...Um_SHo"
}
However, using my code below only provides the following:
{
"access_token": "xxxx....",
"token_type": "Bearer",
"expires_in": 3600
}
I am using the following function to request an access token:
def get_access_token(client_id, client_secret): # getting access token from spotify using client ID
# Encoding Client ID and Client Secret in Base64
token_url = "https://accounts.spotify.com/api/token"
client_creds = f"{client_id}:{client_secret}"
client_creds_b64 = base64.b64encode(client_creds.encode())
token_data = {
"grant_type": "client_credentials"
}
token_headers = {
'Authorization': f"Basic {client_creds_b64.decode()}"
}
r = requests.post(token_url, data=token_data, headers=token_headers)
valid_request = r.status_code in range(200, 299)
token_response_data = r.json()
# pretty print response body
print(json.dumps(token_response_data, indent=2)) # response 200 -> successful attempt
if valid_request:
access_token = token_response_data['access_token']
return access_token
I am unsure why the scope and refresh token are missing from the response body. How can I alter this function to include these?
Thanks in advance for your time!
Spotify documentation: https://developer.spotify.com/documentation/general/guides/authorization/code-flow/

Altering the token data fixes this:
token_data = {
"grant_type": "authorization_code",
"code": "xxxx....",
"redirect_uri": "your redirect uri from Spotify for devs"
}
You need to set up a redirect uri on Spotify for devs, then encode it to use it as a parameter.
To get the 'code' parameter fill-out this URL with your data and you will be redirected to your redirect uri.
https://accounts.spotify.com/authorize?client_id=YOUR CLIENT ID&response_type=code&redirect_uri=YOUR ENCODED REDIRECT URI&scope=playlist-modify-public%20playlist-modify-private
The code will then be in the search bar to copy/paste. It should look something like this:
https://your redirectURI?code=xxx.....

Trying to post data to firestore using requests

im trying to post JSON data to firestore using requests and it keeps returning this error.
{
"error": {
"code": 400,
"message": "Invalid JSON payload received. Unknown name \"{\"data\": \"message\"}\": Cannot bind query parameter. Field '{\"data\": \"message\"}' could not be found in request message.",
"status": "INVALID_ARGUMENT",
"details": [
{
"#type": "type.googleapis.com/google.rpc.BadRequest",
"fieldViolations": [
{
"description": "Invalid JSON payload received. Unknown name \"{\"data\": \"message\"}\": Cannot bind query parameter. Field '{\"data\": \"message\"}' could not be found in request message."
}
]
}
]
}
}
I've tried different method using different types of JSON Encoding and still returns the same error. i would appreciate if someone could look into this for me. Below is my code
def thestream(self, instance):
app = App.get_running_app()
s = requests.Session()
self.data = {u'data': u'message'}
self.headers = {"authorization": "bearer " + app.idToken}
r = s.post("https://firestore.googleapis.com/v1/projects/*******************************/databases/(default)/documents/messages/TemitayoAdefemi", params=json.dumps(self.data), headers=self.headers)
print(r.ok)
print(r.content.decode())

Try defining a Document resource in your payload:
self.data = {u'fields': {u'data': {u"stringValue": u'message'}}}
In your POST request, try passing the payload in data=self.data instead of param:
r = s.post("https://firestore.googleapis.com/v1/projects/***/databases/(default)/documents/messages/TemitayoAdefemi", data=self.data, headers=self.headers)

FCM api 'Bad request 400' error

I'm trying to implement sending notifications via new FCM api protocols. I went through authenticating requests, I enabled api in google console as well. Now when I send request I'm receiving Bad request 400 error. Response doesn't contain any other information than error code and error message. Even reason field says 'Bad Request'. I'm implementing it with FCM api docs.
def fcm_test():
FCM_URL = "https://fcm.googleapis.com/v1/projects/MY_PROJECT_NAME/messages:send"
my_token = "device-token"
payload = {
"massage": {
"token": my_token,
"notification": {
"body": "body",
"title": "title"
}
}
}
payload = json.dumps(payload)
headers = {
"Authorization": "Bearer {auth_token}".format(auth_token=_get_authentication_token()),
"Content-Type": "application/json; UTF-8",
}
try:
request = moves.urllib.request.Request(FCM_URL, payload.encode('utf-8'), headers)
response = moves.urllib.request.urlopen(request, timeout=10)
except Exception as e:
pass
return

There's a typo in your payload key, can you try it again with "message" instead of "massage"?

Can not parse JSON share document.\nRequest body:\n\nError:\nnull

I am trying to send a request to Linkedin's rest share api. I have been receiving this error message:
{
"errorCode": 0,
"message": "Can not parse JSON share document.\nRequest body:\n\nError:\nnull",
"requestId": "ETX9XFEI7N",
"status": 400,
"timestamp": 1437910620120
}
The request is send through the following python code:
import requests,json
auth_token = "some auth token"
url = "https://api.linkedin.com/v1/people/~/shares?format=json&oauth2_access_token="+auth_token
headers = {'content-type': 'application/x-www-form-urlencoded','x-li-format':'json'}
data = {
"comment":"Check out developer.linkedin.com!",
"content":{
"title": "LinkedIn Developers Resources",
"description": "Leverage LinkedIn's APIs to maximize engagement",
"submitted-url": "https://developer.linkedin.com",
"submitted-image-url": "https://example.com/logo.png"
},
"visibility":{
"code": "anyone"
}
}
response = requests.post( url , json= data , headers=headers )
return HttpResponse( response )
I made sure that I followed all the instructions in their documentation and can't find the mistake I am making.
Note: i have tried json=data and data=data both are not working

Remove content-type from the headers dictionary.
requests sets the correct Content-Type when using the json keyword argument.

You have three basic problems:
Please read the documentation on oauth2; because you are not passing in the token correctly.
The share URL does not take a oauth2_token argument.
You have the wrong content-type header.

QPX Express API from Python

I am trying to use Google's QPX Express API from python. I keep running into a pair of issues in sending the request. At first what I tried is this:
url = "https://www.googleapis.com/qpxExpress/v1/trips/search?key=MY_KEY_HERE"
values = {"request": {"passengers": {"kind": "qpxexpress#passengerCounts", "adultCount": 1}, "slice": [{"kind": "qpxexpress#sliceInput", "origin": "RDU", "destination": location, "date": dateGo}]}}
data = json.dumps(values)
req = urllib2.Request(url, data, {'Content-Type': 'application/json'})
f = urllib2.urlopen(req)
response = f.read()
f.close()
print(response)
based upon the code from: urllib2 and json
When I run the above code I get the following error message:
TypeError: POST data should be bytes or an iterable of bytes. It cannot be of type str.
I searched for a solution and adapted my code based upon the following question: TypeError: POST data should be bytes or an iterable of bytes. It cannot be str
I changed my code to this:
url = "https://www.googleapis.com/qpxExpress/v1/trips/search?key=AIzaSyCMp2ZnKI3J91sog7a7m7-Hzcn402FyUZo"
values = {"request": {"passengers": {"kind": "qpxexpress#passengerCounts", "adultCount": 1}, "slice": [{"kind": "qpxexpress#sliceInput", "origin": "RDU", "destination": location, "date": dateGo}]}}
data = json.dumps(values)
data = data.encode("utf-8")
req = urllib2.Request(url, data, {'Content-Type': 'application/json'})
f = urllib2.urlopen(req)
response = f.read()
f.close()
print(response)
However, when I run this code I get the following error message:
urllib.error.HTTPError: HTTP Error 400: Bad Request
I also tried changing utf-8 to ascii but I was unsuccessful. How can I get this working properly?

Here is a solution using the excelent requests library.
import json
import requests
api_key = "YOUR API KEY HERE"
url = "https://www.googleapis.com/qpxExpress/v1/trips/search?key=" + api_key
headers = {'content-type': 'application/json'}
params = {
"request": {
"slice": [
{
"origin": "TXL",
"destination": "LIM",
"date": "2015-01-19"
}
],
"passengers": {
"adultCount": 1
},
"solutions": 2,
"refundable": False
}
}
response = requests.post(url, data=json.dumps(params), headers=headers)
data = response.json()
print data
I am not sure why you request is not working. Maybe it is really the request parameters that were wrong. The date definitely needs to be in the future!

False needs to be in lowercase in JSON, so you need to quote it in Python, like this "refundable" : "false". Otherwise, your query looks good (obviously you'll need to update the date). By the way, it isn't good practice to include your API key in a public forum.
