bad authorization: 400 Bad Request: invalid_grant about go-mastodon

[RasmusLindroth]

That works @RasmusLindroth. However, the AuthenticateToken() works only once. Reuse of the same code seems to be forbidden. Do you have an idea on how to reuse the code? I obviously don't want to register a new app each time I restart my tool

You just run AuthenticateToken() once, then you use:

conf := &mastodon.Config{
	Server:       acc.Server,
	ClientID:     acc.ClientID,
	ClientSecret: acc.ClientSecret,
	AccessToken:  acc.AccessToken,
}
client := mastodon.NewClient(conf)

Now you can use the client for your requests

Wow, it's so easy. That works, thank you!

Probably, your mastodon server stop to support grant_type=password.

Ah, I've added some debug in go-mastodon and it yields: The provided authorization grant is invalid, expired, revoked, does not match the redirection URI used in the authorization request, or was issued to another client

Do you have a code example of using the mastodon.AuthenticateToken function?

Do you have a code example of using the mastodon.AuthenticateToken function?

I'm on my phone so I can't write a good example. But checkout how I do it in tut.

Here's how I register a new account in my program.

https://github.com/RasmusLindroth/tut/blob/2634818c0a1097da935d7137b3620249e679223b/auth/add.go

To use the access token once you have generated it you'll just have to include it in your config like this.

conf := &mastodon.Config{
	Server:       acc.Server,
	ClientID:     acc.ClientID,
	ClientSecret: acc.ClientSecret,
	AccessToken:  acc.AccessToken,
}

The example on the main page fails.

c := mastodon.NewClient(&mastodon.Config{
Server: "https://mstdn.jp",
ClientID: "client-id",
ClientSecret: "client-secret",
})
err := c.Authenticate(context.Background(), "your-email", "your-password")
if err != nil {
log.Fatal(err)
}

atleast when i tried. Need to add accesskey and remove the authenticate part.
