Use SSL with Dart and Managed VM's

Question

I wish to know how I can use a secure connection (https) with Dart and Managed VM's on localhost and when it's deployed.

Thank you.

Answer 1

When an application is deployed using gcloud preview app deploy the default is that the App Engine application will be served on both HTTP and HTTPS. If you have an application on

http://project.appspot.com

you can access it using HTTPS on

https://project.appspot.com

If not accessing the default version the URL are:

http://version.project.appspot.com

and HTTPS on

https://version-dot-project.appspot.com

Note the first . changing to -dot-.

You can specify the following int the app.yaml to only serve the application over HTTPS:

- url: /.*
  script: dummy
  secure: always

This will also redirect from HTTP to HTTPS, but unfortunately not do the rewrite from . to -dot- if not using the default version.

For local development using gcloud preview app run it is not possible to use HTTPS. The following quote is from the App Engine documentation:

The development web server does not support HTTPS connections. It ignores the secure parameter, so paths intended for use with HTTPS can be tested using regular HTTP connections to the development web server.

See https://github.com/dart-lang/appengine/issues/16 and https://cloud.google.com/appengine/docs/python/config/appconfig#Python_app_yaml_Secure_URLs.
