Godoc 无法在浏览器中"像浏览官方包一样" 浏览自定义包

Question

目的 & 重新步骤 & 错误内容

通过godoc命令来在浏览器中浏览自己编写的包,浏览效果和官方提供的包一样;通过查找资料得出以下操作步骤
1 cd /Users/xxx/Desktop/redis-go/src/hosts 切换到自定义包
2 godoc -goroot=. 开启godoc服务
2019/08/06 16:22:34 updateMetadata: open doc: no such file or directory

3 浏览器中输入 http://localhost:6060/pkg/hosts/ 显示的是:cannot find package "." in: /src/hosts
4 浏览器中输入 http://localhost:6060 显示的内容是: 自定包的目录

代码组织

---src
   ---hosts
      --- host.go
      --- doc.go
   ---main
      --- main.go
   --- go.mod
   --- go.sum
  

1. src目录,go.mod,go.sum 在同一级
2. hosts是自定义包

期待答案

• 给出思路与参考内容
• 自己的使用经验

各个文件代码

• host.go

package hosts

import (
    "fmt"
)

//SayHello printf Hell0
func SayHello(){
    fmt.Println("Hello!")
}

doc.go

/*
Package hosts implements custom printf method.
*/
package hosts // import "stephanie.io/hosts"

关于godoc使用的内容

Your own code can present good documentation just by having comments as described above. Any Go packages installed inside $GOROOT/src/pkg and any GOPATH work spaces will already be accessible via godoc's command-line and HTTP interfaces, and you can specify additional paths for indexing via the -path flag or just by running "godoc ." in the source directory. See the godoc documentation for more details.
