kitex服务端设置了GRPC协议，客户端调用报错Not Found: HTTP status code 404

[zhouguanglong1]

前提：使用kitex框架，客户端和服务端通信，使用grpc协议

1. kitex服务端如果是本地启动，在客户端设置client.WithHostPorts(addrs...)，可以正常GRPC请求
2. kitex服务端通过容器化部署，通过域名+端口暴露出来一个入口（入口大概是这样：a.b.c:8088），单独在postman打过去调用是没问题的，此时在客户端通过client.WithHostPorts(addrs...）初始化的，发起GRPC调用就会报以下的错误

Not Found: HTTP status code 404; transport: missing content-type field

请问初始化客户端时，需要调整什么参数，才能顺利打到服务端，目前是这些参数

client.WithTransportProtocol(transport.GRPC),
		client.WithRPCTimeout(time.Second * 3),
		client.WithConnectTimeout(time.Millisecond * 500),
		client.WithFailureRetry(retry.NewFailurePolicy()),
		client.WithErrorHandler(ClientErrorHandler),
		client.WithGRPCKeepaliveParams(grpc.ClientKeepalive{ // 只有GRPC才可以使用
			Time:                ktime,
			Timeout:             ktimeout,
			PermitWithoutStream: permitWithoutStream,
		}),
                 client.WithHostPorts(addrs...),

这个就是完整的报错信息么？在 NewStream 时报的错？
Not Found: HTTP status code 404; transport: missing content-type field

在客户端调用相关的RPC接口的时候的报错

@zhouguanglong1 Is this the complete error message? May I see how you print the error message?

[zhouguanglong1]

@Marina-Sakai
this is RPC request：

func (p *kFeeServiceClient) UserTradeInfo(ctx context.Context, Req *fee.Request, callOptions ...callopt.Option) (r *fee.Response, err error) {
	ctx = client.NewCtxWithCallOptions(ctx, callOptions)
	return p.kClient.UserTradeInfo(ctx, Req)
}

and it returns error
Not Found: HTTP status code 404; transport: missing content-type field

@zhouguanglong1 So sorry for the late reply. This error happens when the header data information is not appropriate. Please check if the containerized deployment could change header data or not.
