如何以父子顺序构造yaml文件？

I want to form a struct using golang via yaml file but I find it difficult to figure out to do it.

api:
  local:
    host: localhost
    port: 8085
  develop:
    host:
    port:
  production:
    host:
    port:
rest-api:
  local:
    host: localhost
    port: 8085
  develop:
    host:
    port:
  production:
    host:
    port:

this is the format in my yaml file

the expected code of this is i want to create a dynamic api url in local, develop and production format like api : local = host+port, same to develop and production to dynamically configure it easily and set up

Would appreciate your help in golang struct and also for your help.

我想通过yaml文件使用golang形成一个结构，但我发现很难弄清楚。< / p> 

  api：
本地：
主机：localhost 
端口：8085 
开发：
主机：
端口：
生产：
主机：\  n端口：
rest-api：
本地：
主机：localhost 
端口：8085 
开发：
主机：
端口：
生产：
主机：
端口：
   
 
 
这是我的Yaml文件中的格式 
 
 
这是我希望在本地创建动态api网址的代码， 和生产格式（如api：local = host + port）一样，可以进行开发和生产以轻松地对其进行动态配置和设置 
 
 
，感谢您在golang结构中的帮助，并为您提供帮助。<  / p>

    This online resource will get you halfway there:

    https://mengzhuo.github.io/yaml-to-go/

    Pasting your yaml yields this:

    type AutoGenerated struct {
    API struct {
        Local struct {
            Host string `yaml:"host"`
            Port int    `yaml:"port"`
        } `yaml:"local"`
        Develop struct {
            Host interface{} `yaml:"host"`
            Port interface{} `yaml:"port"`
        } `yaml:"develop"`
        Production struct {
            Host interface{} `yaml:"host"`
            Port interface{} `yaml:"port"`
        } `yaml:"production"`
    } `yaml:"api"`
    RestAPI struct {
        Local struct {
            Host string `yaml:"host"`
            Port int    `yaml:"port"`
        } `yaml:"local"`
        Develop struct {
            Host interface{} `yaml:"host"`
            Port interface{} `yaml:"port"`
        } `yaml:"develop"`
        Production struct {
            Host interface{} `yaml:"host"`
            Port interface{} `yaml:"port"`
        } `yaml:"production"`
    } `yaml:"rest-api"`
}

    There's obvious sub-type duplicates. So it can be trimmed.

    First pass:

    type Address struct {
    Host string `yaml:"host"`
    Port int    `yaml:"port"`
}

type MyConfig struct {
    API struct {
        Local      Address `yaml:"local"`
        Develop    Address `yaml:"develop"`
        Production Address `yaml:"production"`
    } `yaml:"api"`
    RestAPI struct {
        Local      Address `yaml:"local"`
        Develop    Address `yaml:"develop"`
        Production Address `yaml:"production"`
    } `yaml:"rest-api"`
}

    Second (and final) pass:

    type Address struct {
    Host string `yaml:"host"`
    Port int    `yaml:"port"`
}

type Deployment struct {
    Local      Address `yaml:"local"`
    Develop    Address `yaml:"develop"`
    Production Address `yaml:"production"`
}

type MyConfig struct {
    API     Deployment `yaml:"api"`
    RestAPI Deployment `yaml:"rest-api"`
}
