我的层次结构与此Network -> Serie -> Season -> Episodes
相似。这是一个简化版本,我的真实层次结构有 7 个级别。
我需要使用以下 JSON 对这些对象进行解码/编码:
Network:
{
id: 1,
name: 'Fox'
}
Series:
{
id: 2,
name: 'The Simpsons',
network: {
id: 1,
name: 'Fox'
}
}
Season:
{
id: 3,
name: 'Season 3',
network: {
id: 1,
name: 'Fox'
},
series: {
id: 2,
name: 'The Simpsons'
}
}
Episode:
{
id: 4,
name: 'Pilot',
network: {
id: 1,
name: 'Fox'
},
series: {
id: 2,
name: 'The Simpsons'
},
season: {
id: 3,
name: 'Season 3'
}
}
我尝试像这样组合我的对象:
type Base struct {
ID string `json:"id"`
Name string `json:"name"`
}
type Network struct {
Base
}
type Series struct {
Network // Flatten out all Network properties (ID + Name)
Network Base `json:"network"`
}
type Season struct {
Series // Flatten out all Series properties (ID + Name + Network)
Series Base `json:"series"`
}
type Episode struct {
Season // Flatten out all Season properties (ID + Name + Network + Series)
Season Season `json:"season"`
}
当然,由于"duplicate field error"
,它不起作用.此外,JSON 结果将被深度嵌套。在经典的OOP中,使用普通继承相当容易,在原型语言中,这也是可行的(Object.create/Mixins(
有没有一种优雅的方式来用 golang 做到这一点?我宁愿保持代码干燥。
为什么不重命名礼仪?但是保留 json 标签,然后根据该标签进行封送/取消封送
type Base struct {
ID string `json:"id"`
Name string `json:"name"`
}
type Network struct {
Base
}
type Series struct {
Network // Flatten out all Network properties (ID + Name)
NetworkBase Base `json:"network"`
}
type Season struct {
Series // Flatten out all Series properties (ID + Name + Network)
SeriesBase Base `json:"series"`
}
type Episode struct {
Season // Flatten out all Season properties (ID + Name + Network + Series)
SeasonBase Base `json:"season"`
}
