title: How to upload a file to an storage bucket using an url in python?
body: <p>I want a file to be uploaded to GCP bucket.
  As per my requirement I need it to be uploaded only with Bucket URL and NOT using  blob1.upload</p>
  
  <p>I want to upload to the URL destination as :
  <code>https://storage.googleapis.com/BUCKET_NAME/IrisClassifier.sav</code></p>
  
  <p>when I tried using below I am getting r.status_code as 400:<code>f = open(filename_p)
  r = requests.post(url=bucket_url, files={'file': filename_p})
  print(r.status_code)</code></p>
  
  <p>I gave bucket_url as <a href="https://storage.googleapis.com/BUCKET_NAME" rel="nofollow noreferrer">https://storage.googleapis.com/BUCKET_NAME</a> and filename_p as IrisClassifier.sav as arguments</p>
