go模板中按字段名动态访问结构值

type Person struct {
    Name  string
    Age   int
    Email string
}

templateString := "Name: {{.Name}}, Age: {{.Age}}, Email: {{.Email}}"

tmpl, err := template.New("person").Parse(templateString)
if err != nil {
    // 错误处理
}

person := Person{
    Name:  "John",
    Age:   30,
    Email: "john@example.com",
}

err = tmpl.Execute(os.Stdout, person)
if err != nil {
    // 错误处理
}

Name: John, Age: 30, Email: john@example.com
