Grpc客户端添加请求头（Header）

　　　　　　　var metadata = new Metadata
            {
                { "x-trace-id", $"123456789" }
            };

            var channel = GrpcChannel.ForAddress($"http://172.17.12.175:20026");
            // 开发环境请求地址var client = new UserAudioServiceClient(channel);

            var res = client.AddOrUpdateUserAudio(new Beta.VideoSettings.GrpcServer.AddOrUpdateReuest()
            {
                AudioSynthesisId = "1",
                BetaUnionId = 72057594038339269,
                BusinessId = "180941",
                ModuleId = 57006
            }, metadata); // 添加请求头

        public override async Task<UserAudioReply> GetUserAudio(UserAudioRequest request, ServerCallContext context)
        {
            var replay = new UserAudioReply()
            {
                Status = StatusEnum.Success
            };

            try
            {
                _logger.LogError("dddd");
                var userAudio = await _userAudioQuery.GetUserAudioAsync(
                                                                request.BetaUnionId,
                                                                request.ModuleId,
                                                                request.BusinessId);

                replay.Data = _mapper.Map<UserAudioResult>(userAudio);

            }
            catch (System.Exception e)
            {
                replay.Status = StatusEnum.Fail;
                replay.Msg = "程序出错";
                _logger.LogError("早报内容转音频出错 - GetUserAudio", e);
            }

            return replay;
        }

ServerCallContext context中就可以看到添加的Header头


可在拦截器中添加请求头，interceptor
