The question is about Google App Engine Backend.
How do I find out the backend url on dev server in code ? We have simple url formating rule on production server http://backendName.appName.appspot.com
But url is random on development server, it’s related to some random port http://localhost:xxxx
So how do I find out this dev url in code ?
You can programmatically access backends via Backends API. This also works on dev server.
