Exposing HTTP entrypoints

We will now create a new microservice responsible for handling HTTP requests. First of all, let's amend our imports in the service.py file:

from nameko.rpc import rpc, RpcProxy 
from nameko.web.handlers import http 

Beneath the KonnichiwaService we made earlier, insert the following:

class WebServer: 
 
    name = 'web_server' 
    konnichiwa_service = RpcProxy('konnichiwa_service') 
 
    @http('GET', '/') 
    def home(self, request): 
        return self.konnichiwa_service.konnichiwa() 

Notice how the follows a similar pattern to the KonnichiwaService. It has a name attribute and a method decorated in order to expose it as an entrypoint. In this case, it is decorated with the http entrypoint. We specify inside the http decorator that it is a GET request and the location of that request - in this case, the root of our website.

There is also one more crucial difference: This service holds a reference to the Konnichiwa Service via an RpcProxy object. RpcProxy allows...
