github 里，配图看不了啊

请问为什么会这样呢？

.....\pkg\mod\github.com\micro\[email protected]\server\server.go:51:6: invalid receiver type Server (Server is an interface type)
如果是版本问题，请问需要做那些改变了？

您的博客不能留言，要不还是转战csdn或者简书吧

spell error

microservices-part-3-docker-compose-and-mongodb-with-orm.md 该文档中 **mgo 库的 Copy() 与 Clone()**章节中session.Clonse() 拼写错误。

完成一个运算数字push之后需要在push个空格，否则处理不了2位数的计算

golang-interviews.md 二叉树后序遍历结果错误

原: edgfbac
应为: edgfbca

pulsar-client-go为什么consumer的acktimeout和producer的sendtimeout会被取消呢。

如果pulsar server和consumer网络断链，那没有acktimeout回如何处理呢。

microservices-part-2-use-go-micro-and-dockerising.md syntax error

博客地址:microservices-part-2-use-go-micro-and-dockerising.md
服务端的CreateConsignment和GetConsignments函数里面有点问题
原代码：
func (s *service) CreateConsignment(ctx context.Context, req *pb.Consignment, resp *pb.Response) error {
// 接收承运的货物
consignment, err := s.repo.Create(req)
if err != nil {
return err
}
resp = &pb.Response{Created: true, Consignment: consignment}
return nil
}

// 获取目前所有托运的货物
// func (s *service) GetConsignments(ctx context.Context, req *pb.GetRequest) (*pb.Response, error) {
func (s *service) GetConsignments(ctx context.Context, req *pb.GetRequest, resp *pb.Response) error {
allConsignments := s.repo.GetAll()
resp = &pb.Response{Consignments: allConsignments}
return nil
}
其中resp = &pb.Response{Created: true, Consignment: consignment}
和resp = &pb.Response{Consignments: allConsignments}
对传入的req重新进行了赋值，地址发生了变化

应该用
resp.Created = true resp.Consignment = consignment
和
resp.Consignments = all来进行替换

服务器代码有误，会造成客户端接收不到返回值。

在我的机器上运行，我的客户端接收不到返回值。
经过排查后发现，是服务器该端代码导致的
resp = &pb.Response{Created: true, Consignment: consignment}
局部指针赋值给参数指针，在go函数返回的时候，参数指针所指向的地址会变为原地址（即传入时所指向的地址），由此引发局部指针的复制丢失。客户端收到的返回值永远都是一个内容为空的Response结构体指针。
所以只能改为
resp.Created = true
resp.Consignment = consignment
这样赋值，才会运行正常

在docker中运行服务报错

大侠指教一下，我在docker中运行服务报错，原因不明：
当使用MICRO_REGISTRY:mdns时，docker-compose run consignment-service 提示：2018/12/26 03:04:45 failed to serve: Failed to join multicast group on all interfaces!
当使用默认的consul时（consul已在docker中运行，通过http://localhost:8500都能访问到界面 ），提示：2018/12/26 03:09:56 failed to serve: Put http://127.0.0.1:8500/v1/agent/service/register: dial tcp 127.0.0.1:8500: connect: connection refused

运行是报错

这什么鬼问题啊。
