Spotify API, getting 404 as a response trying to find current song

Am trying to make a program that finds the current song playing and then to put it an one of my playlists. But am getting a 404 response when a trying to obtain the current playing song.

This is how I am getting my access token:

def get_token():
    auth_str = client_id + ":" + client_secret
    auth_bytes = auth_str.encode("utf-8")
    auth_base64 = str(base64.b64encode(auth_bytes), "utf-8")

    url = "https://accounts.spotify.com/api/token"
    headers = {
        "Authorization": "Basic " + auth_base64,
        "Content-Type": "application/x-www-form-urlencoded"
    }
    data = {"grant_type": "client_credentials"}
    result = post(url, headers=headers, data=data)
    json_result = json.loads(result.content)
    token = json_result["access_token"]
    return token

This is how I am creating the headers:

def get_headers(token):
    return {"Authorization": "Bearer " + token}

This is how I am trying to get the current playing song uri:

def get_current_track_and_post_in_playlist(token):
    headers = get_headers(token)
    result = get('https://api.spotify.com/v1/me/player/currently-playing', headers=headers)
    playlist_id = "0p4d0akcszc87kcf0pym6qws1"
    print(result)
    json_result = json.loads(result.content)["item"]["uri"]
    print(json_result)

    playlist_put = post(f'https://api.spotify.com/v1/playlists/{playlist_id}/tracks?uris={json_result}', headers=headers)

When am printing the result in get_current_track_and_post_in_playlist function i get a <Response [404]>. Can someone help me resolve this problem?

A reasons is required a user authentication for those two REST APIs.

Get Currently Playing Track

https://api.spotify.com/v1/me/player/currently-playing

Add Items to Playlist

https://api.spotify.com/v1/playlists/{playlist_id}/tracks

It needs to get token by Authorization Code Flow

So I will demo by local server with Flask

This overall steps enter image description here

# Step 1

I play a song by browser. it will add into my playlist

enter image description here

# Step 2

Running local redirect server with this code with add-song.py file name.

You needs to config the Redirect URIs of your application in your dashboard.

https://developer.spotify.com/dashboard/applications

enter image description here

from flask import Flask, request, redirect
from requests_oauthlib import OAuth2Session
from requests.auth import HTTPBasicAuth
import requests
import json

app = Flask(__name__)

AUTH_URL = 'https://accounts.spotify.com/authorize'
TOKEN_URL = 'https://accounts.spotify.com/api/token'
REDIRECT_URI = 'http://localhost:3000/callback' # your redirect URI
CLIENT_ID = "<your client ID>"
CLIENT_SECRET = "<your client Secret>"
SCOPE = [
    "user-read-playback-state",
    "app-remote-control",
    "user-modify-playback-state",
    "playlist-read-private",
    "playlist-read-collaborative",
    "user-read-currently-playing",
    "user-read-playback-position",
    "user-library-modify",
    "playlist-modify-private",
    "playlist-modify-public",
    "user-read-recently-played",
    "user-read-private",
    "user-library-read"   
]

def get_headers(token):
    return {"Authorization": "Bearer " + token}

@app.route("/login")
def login():
    spotify = OAuth2Session(CLIENT_ID, scope=SCOPE, redirect_uri=REDIRECT_URI)
    authorization_url, state = spotify.authorization_url(AUTH_URL)
    return redirect(authorization_url)

# your redirect URI's path
@app.route("/callback", methods=['GET'])
def callback():
    code = request.args.get('code')
    res = requests.post(TOKEN_URL,
        auth=HTTPBasicAuth(CLIENT_ID, CLIENT_SECRET),
        data={
            'grant_type': 'authorization_code',
            'code': code,
            'redirect_uri': REDIRECT_URI
        })
    access_token = res.json()['access_token']
    listObj = []
    listObj.append(res.json())

    # get current playing
    headers = get_headers(access_token)
    result1 = requests.get(url='https://api.spotify.com/v1/me/player/currently-playing', headers=headers)
    current_song = result1.json()
    listObj.append(current_song)

    # Add new song into playlist with current playing song
    playlist="<your playlist ID>"
    url = "https://api.spotify.com/v1/playlists/{0}/tracks".format(playlist)
    # current_song['item']['uri']  = 'spotify:track:xxxxxxxxxxxxxxxx'
    params = {'uris': current_song['item']['uri']}
    result2 = requests.post(url,
        params=params,
        headers={'Content-Type':'application/json',
            'Authorization': 'Bearer {0}'.format(access_token)})
    added_song = result2.json()    
    listObj.append(added_song)
    return listObj

if __name__ == '__main__':
    app.run(port=3000,debug=True) # your redirect URI's port

$ python add-song.py

#3 Login by Browser

http://localhost:3000/login

login your Spotify credential enter image description here

Before add Song enter image description here

After added Song enter image description here

In the browser, will display current play song information and added song's snapshot_id. enter image description here

The key is playing song's track URI needs to set a parameter of add playlist.

current_song['item']['uri']

#Step 4~6

It is running by inside code.

I hope to this demo your are looking for solution.
