如何通过名称获取struct的属性？

Question

I have this struct definition :

// Two columns, both strings.
type ExampleStructItem struct {
    Firstname string
    Surname string
}

and I have this slice of column names :

columns := []string{"Firstname", "Surname"}

and I am essentially trying to loop through my slice of column names, and then perform reflection on the corresponding struct to get information about the properties, such as their "Kind" etc.

Answer 1

Just use Type.FieldByName()

var ex ExampleStructItem
t := reflect.TypeOf(ex)

for _, name := range columns {

    field, ok := t.FieldByName(name)
    if ok {
        k := field.Type.Kind()
    } else {
        // error handling
    }

}
