使用分隔符打印struct中的字段列表

package main

import (
    "fmt"
    "reflect"
    "strings"
)

type Person struct {
    Name   string
    Age    int
    Gender string
}

func main() {
    p := Person{
        Name:   "Alice",
        Age:    25,
        Gender: "Female",
    }

    printFields(p, ", ")
}

func printFields(s interface{}, separator string) {
    t := reflect.TypeOf(s)
    v := reflect.ValueOf(s)

    for i := 0; i < t.NumField(); i++ {
        field := t.Field(i)
        value := v.Field(i)

        fmt.Printf("%s: %v%s", field.Name, value.Interface(), separator)
    }

    fmt.Println()
}

Name: Alice, Age: 25, Gender: Female,
