英文:
Is there a way to construct a grpc server on a connected socket net.conn?
问题
在Go语言中的典型用法是：
server := grpc.NewServer()
pb.RegisterUserServer(server, &userSrvc.UserServer{})
addr := ":" + env.GetMyRpcPort()
lis, _ := net.Listen("tcp", addr)
server.Serve(lis)
我想知道是否可以在已连接的conn上运行服务器，像这样：
conn, _ := net.Dial("tcp", ":8080")
server.Serve(conn)
客户端首先连接到服务器，然后在已连接的net.conn上构建一个gRPC服务器，然后服务器可以通过RPC调用客户端，向客户端推送一些消息作为请求。

The typical usage in go is:
server := grpc.NewServer()
pb.RegisterUserServer(server, &userSrvc.UserServer{})
addr := ":" + env.GetMyRpcPort()
lis, _ := net.Listen("tcp", addr)
server.Serve(lis)
I wonder can I run a server on a connected conn like:
conn, _ := net.Dial("tcp",":8080")
server.Serve(conn)
The client connect to the server first, and then construct a grpc server on the connected net.conn, then the server can rpc call the client to push some message as a request to the client.

我认为你需要一个双向流式传输。
这里有一个使用Go语言实现双向GRPC的详细示例：https://github.com/pahanini/go-grpc-bidirectional-streaming-example。
conn, err := grpc.Dial(":50005", grpc.WithInsecure())
...
client := pb.NewMathClient(conn)
stream, err := client.Max(context.Background())
...
req := pb.Request{Num: rnd}
err := stream.Send(&req)
英文:
I think that you need a bidirectional streaming.
Here is one elaborated example of using bidirectional GRPC in Go: https://github.com/pahanini/go-grpc-bidirectional-streaming-example.
conn, err := grpc.Dial(":50005", grpc.WithInsecure())
...
client := pb.NewMathClient(conn)
stream, err := client.Max(context.Background())
...
req := pb.Request{Num: rnd}
err := stream.Send(&req)
