generate(client, bucket, filename, opts \\ [])

View Source
This function is deprecated. Use GcsSignedUrl.generate_v4/4 instead. [V2 signing process is considered legacy](https://cloud.google.com/storage/docs/access-control/signed-urls-v2). 
@spec generate(GcsSignedUrl.Client.t(), String.t(), String.t(), sign_v2_opts()) ::
  String.t()
@spec generate(
  GcsSignedUrl.SignBlob.OAuthConfig.t(),
  String.t(),
  String.t(),
  sign_v2_opts()
) ::
  {:ok, String.t()} | {:error, String.t()}

If the first argument is a GcsSignedUrl.Client{}: Generate V2 signed url using its private key.

If the first argument is a %GcsSignedUrl.SignBlob.OAuthConfig{}: Generate V2 signed url using the Google IAM REST API with a OAuth2 token of a service account.
