Go 如何以父子顺序构造yaml文件？

我想通过yaml文件使用golang来形成一个结构，但我发现很难做到这一点

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:

这是我的yaml文件中的格式

预期的代码是我想创建一个本地、开发和生产格式的动态api url，如api:local=host+port，与开发和生产相同，可以轻松地动态配置和设置它

非常感谢您在golang struct中的帮助以及您的帮助。

此在线资源将帮助您完成以下任务：

粘贴yaml会产生以下结果：

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"`
}

有明显的子类型重复。所以它可以被修剪

第一遍：

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"`
}

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"`
}

第二次（和最后一次）通过：

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"`
}

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"`
}
