如何获得源代码中的变量名(使用反射) [英] How to get the variable name as in the source code (using reflect)

问题描述

我正在尝试构建一个易于使用的模板系统.基本上，我只想创建一个具有不同变量(字符串)的切片，然后遍历该切片并将标记 {{}} 替换为实际值.因此，如果变量' name '是 onevar ，它将在模板中查找 {{onevar}} 并将其替换为的实际值变量.

I'm trying to build an easy to use templating system. Basically I just want to create a slice with different variables ( strings ) and then loop through the slice and replace the markup {{}} with the actual values. So if the variable 'name' is onevar it will look in the template for {{onevar}} and replace that with the actual value of the variable .

问题:如何获取变量名?基本上，源代码中包含什么.是否可以 ?我已经尝试过使用反射功能，但是似乎无法正确处理.见下文g

Question: how do I get the variable name? Basically what's in the source code. Is it possible ? I've tried something with reflect but seems I couldn't get it right. See belowg

onevar := "something"
other := "something else"

var msg string
    sa := []string{onevar, other}
    for _, v := range sa {
        vName := reflect.TypeOf(v).Name()
        vName = fmt.Sprintf("{{%s}}", vName)
        msg = strings.Replace(msg, vName, v, -1)
    }

推荐答案

您不能做这些事情.该分片不不包含变量，但包含它们的值，因此您无法获得它们的名称.只需使用地图即可.

You cannot do such stuff. The slice does not contain the variables but their values, so you cannot get their name. Just use a map.
