Let's make a spot sale service 3

Now that the DB design for the item management function is complete, let's create an api. The required api is

  1. Create a circle
  2. Get circle information
  3. Update circle information
  4. Item registration
  5. Get item information
  6. Item information update
  7. List of registered items

What a place, such as. There are quite a few.

This time I made a circle around. You can create a circle and change the icon and circle name.

New things I learned

About webapp2

When handling the image received by multipart / form-data (key is'circlecut')

Can access

cloud storage

Use Google Cloud Storage Python Client Library to access Cloud Storage on GAE https://developers.google.com/appengine/docs/python/googlecloudstorageclient/?hl=ja

Writing files to GCS

controller/user/api/circle.py


circlecutBlob  = self.request.get('circlecut')
circlecutType  = self.request.params["circlecut"].type

circlecutHash = hashlib.md5(circlecutBlob).hexdigest()
circlecutpath = Common.createCirclecutPath(circlecutHash)

gcs_file = gcs.open(circlecutpath,
						'w',
						content_type=circlecutType,
						options={},
						retry_params=gcs.RetryParams(backoff_factor=1.1))
gcs_file.write(circlecutBlob)
gcs_file.close()

The image that was sent by the POST request multipart / form-data is saved in CloudStorage with the file path of'/ freemarket / circlecut / MD5'. Recent App Engine has CloudStorage for local environment, and if it is the file saved this time, you can check it from the browser in the form of http: // localhost: 8080 / _ah / gcs / freemarket / circlecut / xxxxxx after starting devserver.

Remaining tasks

  1. Item registration
  2. Get item information
  3. Item information update
  4. List of registered items

Future tasks
