Download file from google cloud storage using ruby client gets HTTP redirect -

-

i trying download file gcs using ruby client , service account authorization; here code: 

def build_client   client = google::apiclient.new()   key = google::apiclient::pkcs12.load_key(service_account_pkcs12_file_path, 'notasecret')   service_account = google::apiclient::jwtasserter.new(       service_account_email,       'https://www.googleapis.com/auth/devstorage.full_control',   key)   client.authorization = service_account.authorize   client end  client = build_client storage = client.discovered_api('storage', 'v1beta2')  #get (download) specific object bucket bucket_get_result = client.execute(     api_method: storage.objects.get,     parameters: {bucket: bucket, object: params[:file_name], alt: 'media'} ) puts bucket_get_result.body

the result body redirect detail follows:

<html> <head> <title>temporary redirect</title> </head> <body bgcolor="#ffffff" text="#000000"> <h1>temporary redirect</h1> document has moved <a     href="https://storage.googleapis.com/my_bucket_name/my_file_name">here</a>. </body> </html>

...and if try go redirect 'location' unauthorized http. so, how can download file gcs using ruby client? https://developers.google.com/storage/docs/json_api/v1/objects/get says:

if provide url parameter alt=media, respond object data in response body

the google ruby api client not support downloading media.

however, rest of work yourself.

require 'httparty'  get_result = bucket_get_result = client.execute(     api_method: storage.objects.get,     parameters: {bucket: bucket, object: params[:file_name], :alt=>'media'}) url = get_result.response.env[:response_headers]['location'] token = "bearer #{bucket_get_result.request.authorization.access_token}" puts httparty.get(url, :headers => {"authorization" => token}).body
