I am trying to run the Google Cloud Storage + Google App Engine (Python) Hello World application.
I followed the instructions to activate Google Cloud Storage and created a bucket from the App Engine application console. I wrote a trivial program to write a test file, but when I run it, the cloud storage library throws 403, apparently because my App Engine application credentials are not presented, are invalid or do not have the right to this bucket.
Here is the code:
BUCKET = '/pcj-info-testing'
class TestGCS(webapp2.RequestHandler):
def create_file(self, filename):
self.response.write("Creating\n");
gcs_file = gcs.open(filename, 'w', content_type = 'text/plain');
gcs_file.write('Testing, 1, 2, 3\n')
gcs_file.write('At ' + datetime.now().isoformat())
gcs_file.close()
def get(self):
self.response.headers['Content-Type'] = 'text/plain'
filename = BUCKET + "/demo-file" + str(random.randrange(10**10, 10**11-1))
self.create_file(filename)
self.response.write('File stat:\n')
stat = gcs.stat(filename)
self.response.write(repr(stat))
and here is the relevant part of the stack trace and error:
