Question

我想通过yaml文件使用golang来形成结构，但是我发现很难找出答案。

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

这是我想要的代码，我想以本地，开发和生产格式创建一个动态api url，例如api：local = host + port，要进行开发和生产，以轻松地对其进行动态配置和设置

非常感谢您在golang结构中的帮助，也为您提供帮助。

此在线资源将使您半途而废：

粘贴您的Yaml会得到以下结果：

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项。这样就可以修剪。

首次通过：

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"`
}

第二次（也是最后一次）通过：

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"`
}

如何以父子顺序构建yaml文件？
