Multiple custom domains to specific version of Google App Engine app

问题

Let's say I have myapp.appspot.com and two custom domains respectively called foo.com and bar.com. How do I configure Google App Engine (GAE) such that:

(www.)foo.com -> foo.myapp.appspot.com

(www.)bar.com -> bar.myapp.appspot.com

(www.)foo.com -> myapp.appspot.com (default version)

I'm reading https://developers.google.com/appengine/docs/domain but I still don't understand how to configure it. I get the impression that GAE only supports wildcard for one custom domain e.g. **.foo.com.

回答1:

You can't really do that directly, as you associate your custom domain with an App ID rather than the App URL.

I guess you could map both foo.com and bar.com to your App ID, then in the default version of your App Engine parse the URL, and redirect accordingly, but it's not a great solution as you would be redirecting from your custom domain back to appspot.com domain.

You can route using the dispatch file (dispatch.yaml).

This blog post gave me the necessary info, and I imagine for the case of needing to map multiple domains to different modules would require a dispatch.yaml something like this:

# Dispatch
# ========
---
dispatch:
  - url: 'foo.com/*'
    module: foo
  - url: 'bar.com/*'
    module: bar

Don't forget to add the custom domains as well as SSL certs in the App Engine console.
