在App Engine中使用rpc / jsonrpc

I'm confused reading "rpc" and "rpc/jsonrpc" code and docs. We won't listen to a port to serve RPC requests on App Engine, I mean, we won't "start a server", so how it should work?

Basically, you can't. That's only the first problem you'll hit. The second major problem you'll find is that you can't get at the *http.Request to get an appengine.Context to do anything useful with App Engine in your RPC handler.
