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.

This online resource will get you halfway there:

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"`
}
