Support subdomain isolation for GHES hosts #500
Description
Right now we take a GHES hostname and use same domain, but actually subdomain isolation can be optionally enabled, and then for example https://{domain}/raw becomes https://raw.{domain}
func newGHESHost(hostname string) (apiHost, error) {
u, err := url.Parse(hostname)
if err != nil {
return apiHost{}, fmt.Errorf("failed to parse GHES URL: %w", err)
}
restURL, err := url.Parse(fmt.Sprintf("%s://%s/api/v3/", u.Scheme, u.Hostname()))
if err != nil {
return apiHost{}, fmt.Errorf("failed to parse GHES REST URL: %w", err)
}
gqlURL, err := url.Parse(fmt.Sprintf("%s://%s/api/graphql", u.Scheme, u.Hostname()))
if err != nil {
return apiHost{}, fmt.Errorf("failed to parse GHES GraphQL URL: %w", err)
}
uploadURL, err := url.Parse(fmt.Sprintf("%s://%s/api/uploads/", u.Scheme, u.Hostname()))
if err != nil {
return apiHost{}, fmt.Errorf("failed to parse GHES Upload URL: %w", err)
}
rawURL, err := url.Parse(fmt.Sprintf("%s://%s/raw/", u.Scheme, u.Hostname()))

baseRESTURL: restURL,
graphqlURL: gqlURL,
uploadURL: uploadURL,
rawURL: rawURL,
}, nil
