我正在嘗試為 etcd v3+ 實(shí)現(xiàn) C# GRPC 客戶端。我能夠通過無身份驗證和通道 ssl 身份驗證進(jìn)行連接。但是，我也在嘗試找出基本的身份驗證機(jī)制。這是我的實(shí)現(xiàn)。using System;using System.Threading.Tasks;using System.Collections.Generic;using Grpc.Core;using Etcdserverpb;using Google.Protobuf;using System.Runtime.CompilerServices;using Grpc.Auth;using Grpc.Core.Interceptors;namespace myproj.etcd{    public class EtcdClient    {               Channel channel;        KV.KVClient kvClient;        string host;        string username;        string password;        string authToken;        Auth.AuthClient authClient;        public EtcdClient(string host, string username, string password)        {            this.username = username;            this.password = password;            this.host = host;                             Authenticate();            // Expirementing with the token, trying to achieve my goal.            channel = new Channel(host, ChannelCredentials.Create(ChannelCredentials.Insecure,                                                                GoogleGrpcCredentials.FromAccessToken(this.authToken)));            // This works.            //channel = new Channel(host, ChannelCredentials.Insecure);            kvClient = new KV.KVClient(channel);        }        void Authenticate()        {            authClient = new Auth.AuthClient(new Channel(host,ChannelCredentials.Insecure));            var authRes = authClient.Authenticate(new AuthenticateRequest            {                Name = username,                Password = password            });            this.authToken = authRes.Token;        }使用authenticate()方法，我能夠從 etcd 服務(wù)器獲取令牌，但無法找到在后續(xù)調(diào)用（Get、Put 等）中使用相同令牌的方法。
