C# - etcd GRPC 客户端基本认证

Question

我正在尝试为 etcd v3+ 实现一个 C# GRPC 客户端。我能够通过无身份验证和通道 ssl 进行连接 auth.However，我正在尝试找出基本的身份验证机制 well.Here到现在为止是我的实现。

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;

        }

        public string Get(string key)
        {
            try
            {
                var rangeRequest = new RangeRequest { Key = ByteString.CopyFromUtf8(key) };
                var rangeResponse = kvClient.Range(rangeRequest);
                if (rangeResponse.Count != 0)
                {
                    return rangeResponse.Kvs[0].Value.ToStringUtf8().Trim();
                }
            }
            catch (Exception ex)
            {

            }
            return String.Empty;
        }

    }
}

使用 authenticate() 方法，我能够从 etcd 服务器获取令牌，但无法找到在后续调用（Get、Put 等）中使用相同令牌的方法。 ).

可以找到用于生成客户端代码的Protobuf文档here

更新： 如果有人想查看完整的源代码，这里是 link to project.

Answer 1

我参考RESTapi文档解决了here.

添加私人属性.

Metadata headers;

已更新 Autheticate() 以添加身份验证 header。

headers = new Metadata();
headers.Add("Authorization", authToken);

已更新 Get() 以通过 header。

var rangeResponse = kvClient.Range(rangeRequest, headers);
