使用证书的服务端

package main

import (
    "google.golang.org/grpc"
    "google.golang.org/grpc/credentials"
    "grpcpro/services"
    "log"
    "net"
)

func main() {
    creds, err := credentials.NewServerTLSFromFile("keys/server.crt", "keys/server_no_passwd.key")
    if err != nil {
        log.Fatal(err)
    }
    rpcServer := grpc.NewServer(grpc.Creds(creds))
    services.RegisterProdServiceServer(rpcServer, new(services.ProdService))
    lis, _ := net.Listen("tcp", "8081")
    rpcServer.Serve(lis)
}
