How to use go-vcr with githubv4 ? - getting httpClient Transport

Looking at the set up for go-vcr

// Start our recorder
	r, err := recorder.New("fixtures/etcd")
	if err != nil {
		log.Fatal(err)
	}
	defer r.Stop() // Make sure recorder is stopped once done with it

	// Create an etcd configuration using our transport
	cfg := client.Config{
		Endpoints:               []string{"http://127.0.0.1:2379"},
		HeaderTimeoutPerRequest: time.Second,
		Transport:               r, // Inject as transport!
	}

Attempting to use this library using the githubv4 library seems at though it needs a way to handle Oauth

import "golang.org/x/oauth2"

func main() {
	src := oauth2.StaticTokenSource(
		&oauth2.Token{AccessToken: os.Getenv("GITHUB_TOKEN")},
	)
	httpClient := oauth2.NewClient(context.Background(), src)

	client := githubv4.NewClient(httpClient)
	// Use client...
}

I'm not sure how to get the recorder 'r' into the oauth2 client. If at all possible.

Has anyone been successful with this? I've tried passing in a httpClient with the 'r' recorder but it ends up as a 401 - looks like this default client can't do the Oauth dance.

I'd like to use the GraphQL API but can fall back to the REST API if is is easier but I just want to make sure this isn't really possible. Has anyone else been successful with this?

This issue resolved this question for me.

)
func TestGithub(t *testing.T) {
//custom http.Transport, since github uses oauth2 authentication
ts := oauth2.StaticTokenSource(
&oauth2.Token{AccessToken: "YOUR_GITHUB_TOKEN"},
)
tr := &oauth2.Transport{
Base:  http.DefaultTransport,
Source: oauth2.ReuseTokenSource(nil, ts),
}
// Start our recorder
vcrRecorder, err := recorder.NewAsMode(path.Join("testdata", "fixtures", t.Name()), recorder.ModeRecording, tr)
require.NoError(t, err)
defer vcrRecorder.Stop() // NEWLY ADDED CODE HERE
// Filter out dynamic & sensitive data/headers
// Your test code will continue to see the real access token and
// it is redacted before the recorded interactions are saved
// =====> commenting out this section has no impact on missing recording
vcrRecorder.AddSaveFilter(func(i *cassette.Interaction) error {
delete(i.Request.Headers, "Authorization")
delete(i.Request.Headers, "User-Agent")
i.Request.Headers["Authorization"] = []string{"Basic UExBQ0VIT0xERVI6UExBQ0VIT0xERVI="} //PLACEHOLDER:PLACEHOLDER
return nil
})
// custom http.client
httpClient := &http.Client{
Transport: vcrRecorder,
}
ghClient := github.NewClient(httpClient)
// =====> actual test, should create cassettes, but does not.
_, _, err = ghClient.Users.Get(context.Background(), "")
require.NoError(t, err)
