Upload files to Google cloud storage from appengine app

Question

I\'m sure the answer to this question is easy, but for me it\'s proven to be very frustrating since I can\'t put any solution I\'ve found into practical code for my own use.

Answer 1

I have created a gist showing how to upload and use GCS files: https://gist.github.com/voscausa/9541133

This is the code to handle the multipart form post:

class GcsUpload(webapp2.RequestHandler):

    def post(self):

        field_storage = self.request.POST.get("file", None)
        if isinstance(field_storage, cgi.FieldStorage):
            file_name = field_storage.filename

            dyn = gcs_data.Dynamics(id=file_name, filename=file_name)
            gcs_file_name = gcs_data.gcs_write_blob(dyn, field_storage.file.read())
            gcs_data.gcs_serving_url(dyn)
            dyn.put()
            logging.info('Uploaded and saved in default GCS bucket : ' + gcs_file_name)

            self.response.headers[b'Content-Type'] = gcs_data.gcs_content_type(dyn)
            self.response.write(gcs_data.gcs_read_blob(dyn))

        else:
            logging.error('GCS Upload failed')
