How should I create a Google App Engine service visible only within my project? -


i'd create google app engine service use microservice. i'd api accessible callers within project's network (i.e., google compute engine , gae instances on project). what's easiest way restrict access this?

i see how run private modules on google app engine? check x-appengine-inbound-appid works requests gae, doesn't requests gce.

to restrict gce service use networking. don't think gae instances can assigned networks though.

check if x-appengine-inbound-appid matches app id.

https://cloud.google.com/appengine/docs/python/appidentity/

appengine identity api doc contains using x-appengine-inbound-appid asserting identity.

import webapp2   class mainpage(webapp2.requesthandler):      allowed_app_ids = [         'other-app-id',         'other-app-id-2'     ]      def get(self):         incoming_app_id = self.request.headers.get(             'x-appengine-inbound-appid', none)          if incoming_app_id not in self.allowed_app_ids:             self.abort(403)          self.response.write('this protected page.')  app = webapp2.wsgiapplication([     ('/', mainpage) ], debug=true)

serialization - Convert Any type in scala to Array[Byte] and back -

i have following question: i have variable value in program declared value. i want convert value byte array.. how can serialize byte array , back? found examples related other types such double or int, not any. this should need. it's pretty similar how 1 in java. import java.io.{bytearrayinputstream, bytearrayoutputstream, objectinputstream, objectoutputstream} object serialization extends app { def serialise(value: any): array[byte] = { val stream: bytearrayoutputstream = new bytearrayoutputstream() val oos = new objectoutputstream(stream) oos.writeobject(value) oos.close stream.tobytearray } def deserialise(bytes: array[byte]): = { val ois = new objectinputstream(new bytearrayinputstream(bytes)) val value = ois.readobject ois.close value } println(deserialise(serialise("my test"))) println(deserialise(serialise(list(1)))) println(deserialise(serialise(map(1 -> 2)))) println(deserialise(seri
