I have been trying to create a signedurl using gsutil of google cloud storage, I have been using python from my windows machine Till now what I have done is

  • Created a service account from google's developer console
  • Then from my python I have executed this command to configure service account "gsutil config -e"
  • Then given my credential information as asked by the console
  • Then I tried to create a signed url for one of my object using following command
  • python gsutil signurl -d 10m -p notasecret p12file.p12 gs://{my bucket}/{my object}
  • This gave me this output with error message

https://storage.googleapis.com/support-videos/[email protected]&Expires=1409209504&Signature=GI5Uo8XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX4hHzPqq1c%3D

[email protected] does not have permissions on gs://{my bucket}/{my object} using this link will likely result in a 403 error until at least READ permissions are granted

I have given read permission to all users on object

Please, Help me out of this, I have been stuck on this for 2 days...

Is your long-term plan to restrict access to the object without a signed URL? If anonymous user have read access to the object, there's no reason you need to use signed URLs at all. – Brandon Yarbrough
Also, followup question, does the generated URL work correctly? – Brandon Yarbrough
I am facing this problem with space in file name I am using this python command python gsutil signurl -d 10m -p notasecret key.p12 "gs://bucket/File name with space check.txt" and it is giving me "SignatureDoesNotMatch" error <StringToSign> /buckethha/File%20name%20with%20space%20check.txt </StringToSign> – Parag Bhayani
Interesting. I think you have discovered a gsutil bug. I will file it in the appropriate place. For now, can you try replacing the space with a %20 in the command line, as in the following and let me know if it works? gsutil signurl key.p12 gs://bucket/File%20name%20with%20spaces.txt – Brandon Yarbrough
@BrandonYarbrough Nope that doesn't work, and it even doesn't show any error message, it just shows empty white browser page ... No XML Error Response – – Parag Bhayani

The file I was trying to access has spaces in its name due to some bugs with urlencoding I wasn't able to create proper url for it ...

So for files without spaces works fine with me
