在Go语言中查找结构体的匿名字段的底层类型。

Find underlying anonymous field type for struct in Go

问题

我有这两个结构体:

type CustomTime struct {
    time.Time
}

type Events struct {
    Timestamp CustomTime
}

当我使用 reflect 获取 Events.Timestamp 字段时,我得到的是 CustomTime,我该如何获取实际的底层类型 time.Time

英文:

I have these two structs:

type CustomTime struct {
	time.Time
}

type Events struct {
	Timestamp CustomTime
}

When I reflect the field for Events.Timestamp, I get CustomTime; how can I get the actual underlying type which is time.Time?

这是一个Go Playground的示例,展示了如何访问匿名字段。

https://play.golang.org/p/yQULMVaQK0

基本上,一旦你有了结构体的值,你就可以从第0个字段获取Time值。

英文:

Here is a go playground example showing how you can access the anonymous field.

https://play.golang.org/p/yQULMVaQK0

Basically, once you have the value of the struct you should be able to get the Time value from field 0
