如何通俗易懂的理解gRPC stub的概念，起什么样的作用，运行机理如何？

Answer 1

gRPC Concepts:

On the client side, the client has a local object known as stub(for some languages, the preferred term is client) that implements the same methods as the service. The client can then just call those methods on the local object, wrapping the parameters for the call in the appropriate protocol buffer message type - gRPC looks after sending the request(s) to the server and returning the server’s protocol buffer response(s).

就是一个客户端。
