I keep getting "Missing required parameter: client_id" on authentication example

[percit]

Hi, so I am trying to get authentication example to work, but I keep getting "Missing required parameter: client_id". After manualy pasting my client ID from Spotify I just get "This site can’t be reachedlocalhost refused to connect.". My spotify redirectUri is set correctly, so I am not sure what to do more. Can anybody help me?

[TimHi]

I'm assuming you are trying to run authenticate.go. Are you sure the redirect url is set up correctly?

You need to register http://localhost:8080/callback as mentioned here. Also the missing client id is probably due to you not having the enviroment variable set as mentioned in the comment aswell.

yeah, I do have redirect URI, and added client_id and client secret, like this: auth := spotifyauth.New( spotifyauth.WithClientID(SpotifyClientID), spotifyauth.WithClientSecret(SpotifyClientSecret), spotifyauth.WithRedirectURL(redirectURI), spotifyauth.WithScopes( spotifyauth.ScopePlaylistModifyPublic, spotifyauth.ScopePlaylistModifyPrivate, ), ) and it parses client_id correctly now, but in URI that I got from app, I cannot find client secret, and I get "404 page not found"

[TimHi]

It's normal that the client secret is not part of the URL. That exchange will happen when the tokes are requested, see docs.

The redirectURI from spotifyauth.WithRedirectURL(redirectURI) is registered in your spotify app? From the authcode example it should look like this:

If that is setup correctly the example should run just fine. Maybe you have external tools (firewall, proxy ..) that block the access of your localhost

yes, I have uri. And no, I don't have any problem with localhost, as I used it many times before in previous golang projects. Is there a chance that golang spotify api has a bug? Have you tried using this authenticate.go recently?

[TimHi]

Yes, running the authcode/authenticate.go example works without issues, I'm even using the scopes from your code:

...
// redirectURI is the OAuth redirect URI for the application.
// You must register an application at Spotify's developer portal
// and enter this value.
const redirectURI = "http://localhost:8080/callback"

var (
    auth = spotifyauth.New(spotifyauth.WithRedirectURL(redirectURI), spotifyauth.WithScopes(
        spotifyauth.ScopePlaylistModifyPublic,
        spotifyauth.ScopePlaylistModifyPrivate,
    ), spotifyauth.WithClientID("ClientID"), spotifyauth.WithClientSecret("ClientSecret"))
    ch    = make(chan *spotify.Client)
    state = "abc123"
)
...

PS go run .\authenticate.go
Please log in to Spotify by visiting the following page in your browser: https://accounts.spotify.com/authorize?client_id=ClientID&redirect_uri=http%3A%2F%2Flocalhost%3A8080%2Fcallback&response_type=code&scope=playlist-modify-public+playlist-modify-private&state=abc123
